[Перевод] С новым годом: GPT в 500 строках на SQL

В минувшем году все только и говорили об ИИ и о том, как он может всё за вас сделать.

Мне нравится, когда кто-то или что-то работает за меня. Поэтому решил: попрошу-ка ChatGPT написать за меня новогодний пост:

"Эй, ChatGPT. А ты можешь реализовать большую языковую модель на SQL?"
"Нет, SQL не подходит для реализации больших языковых моделей. Язык SQL предназначен для выполнения запросов к данным, хранящимся в РСУБД и для управления этими запросами. Для реализации большой языковой модели требуются сложные алгоритмы, обширные датасеты, а зачастую – и фреймворки для глубокого обучения. SQL всеми этими возможностями не обладает."

Что ж, лишний раз убеждаешься, что, если хочешь что-то сделать хорошо – сделай это сам.

Давайте же воодушевимся этим оптимистическим планом и реализуем большую языковую модель на языке SQL.

Теория

Готовя этот пост, я вдохновлялся чудесной статьёй GPT in 60 Lines of NumPy, которую написал Джей Моди. В этой статье объяснено внутреннее устройство модели GPT, причём, это сделано гораздо лучше, чем могло бы получиться у меня. Поэтому для порядка вкратце напомню контекст.

Что представляет собой генеративная большая языковая модель с технической точки зрения?

Генеративная LLM – это функция. Она принимает на ввод текстовую последовательность символов (в терминологии ИИ она называется «промпт») и возвращает массив строк и чисел. Вот какова сигнатура этой функции:

llm(prompt: str) -> list[tuple[str, float]]

Это детерминированная функция. У неё под капотом выполняется серьёзная математика, но вся эта математика жёстко вшита в систему. Если вы будете многократно сообщать этой функции один и тот же ввод, то всякий раз будете получать от неё один и тот же вывод.

Тем, кому доводилось пользоваться ChatGPT и подобными продуктами, это может показаться удивительным, ведь система может давать разные ответы на один и тот же вопрос. Да, всё верно. Чуть ниже объясню, как это устроено.

Что за значения возвращает эта функция?

Нечто подобное:

	llm("I wish you a happy New")
 
0       (' Year', 0.967553)
1       (' Years', 0.018199688)
2       (' year', 0.003573329)
3       (' York', 0.003114716)
4       (' New', 0.0009022804)
…
50252   (' carbohyd', 2.3950911e-15)
50253   (' volunte', 2.2590102e-15)
50254   ('pmwiki', 1.369229e-15)
50255   (' proport', 1.1198108e-15)
50256   (' cumbers', 7.568147e-17)

Она возвращает массив кортежей. Каждый кортеж состоит из слова (скорее, строки) и числа. Число — это вероятность, с которой данное слово может оказаться промпте на следующей позиции. Модель «думает», что за фразой «I wish you a happy New…» («Поздравляю тебя с Новым…») с вероятностью 96,7% последует строка «Year» (…годом) – и так далее.

Слово «думает» выше поставлено в кавычках, так как, естественно, модель ни о чём не думает. Она механически возвращает массивы слов и чисел в соответствии с некоторой жёстко прописанной внутренней логикой.

Если эта система такая топорная и детерминированная, как же ей удаётся генерировать разные тексты?

Большие языковые модели используются в текстовых приложениях (чатботы, генераторы контента, кодинг-ассистенты, т.д.). Эти приложения раз за разом вызывают модель и выбирают подсказанное ею слово (с некоторой степенью произвольности). Последнее предложенное слово добавляется к промпту, и модель вызывается снова. Этот цикл продолжается до тех пор, пока не будет сгенерировано достаточное количество слов.

Накопленная таким образом последовательность слов выглядит как текст на естественном языке, с полноценной грамматикой, синтаксисом и даже мнимыми признаками интеллекта и логики. В данном отношении языковые модели подобны марковским цепям, работающим по такому же принципу.

На внутреннем уровне большая языковая модель устроена так, что каждое последующее предлагаемое слово естественным образом продолжало промпт, с учётом имеющейся грамматики, семантики и тональности. Оснастить функцию такой логикой стало возможно благодаря целой серии научных прорывов (и каторжной работе программистов). Удалось разработать целое семейство алгоритмов под названием GPT или «генеративные предобученные трансформеры».

Что такое "генеративный предобученный трансформер"

«Генеративный» означает, что алгоритм генерирует текст (рекурсивно достраивая продолжения к промпту как было показано выше).

«Трансформер» означает, что алгоритм использует конкретный тип нейронной сети. Сеть-трансформер была разработана компанией Google и описана в этой статье.

Термин «предобученный» требует небольшого исторического экскурса. Изначально считалось, что способность модели достраивать текст – это всего лишь предпосылка для получения более глубоких логических выводов в рамках специализированных задач (нужно улавливать логическую связь между фразами), классификации (например, угадать, сколько звёзд у отеля, проанализировав отзывы постояльцев), машинного перевода и т.д. Считалось, что две эти части алгоритма требуется обучать отдельно, и языковая часть позиционировалась как предобучение, подготовка к последующему обучению решать реальную задачу.

Как сформулировано в исходной статье по GPT:

Продемонстрировано, что возможно добиться больших успехов при решении таких задач путём генеративного предобучения языковой модели на разнородном корпусе неразмеченного текста с последующей тонкой настройкой различных параметров для различных слоёв сети (discriminative fine-tuning) в контексте каждой конкретной задачи.

Такие представления сохранялись до тех пор, пока не стало понятно, что для достаточно большой модели второй шаг зачастую излишен. Модель-трансформер, обученная исключительно генерации текстов, оказалась в состоянии без дополнительного обучения следовать человеческим инструкциям, содержащимся в этих текстах. Таким образом, не требовалось никакой дополнительной тонкой настройки.

Итак, с этими вопросами мы разобрались. Теперь давайте сосредоточимся на реализации.

Генерация

Вот что происходит, если мы пытаемся сгенерировать текст на основе промпта при помощи GPT2:

def generate(prompt: str) -> str:
  # Преобразует строку в список токенов.
  tokens = tokenize(prompt) # tokenize(prompt: str) -> list[int]
 
  while True:
 
    # Выполняет алгоритм.
    # Возвращает вероятностные значения для токенов: список из 50257 чисел с плавающей точкой, в сумме дающих 1.
    candidates = gpt2(tokens) # gpt2(tokens: list[int]) -> list[float]
 
    # Выбирает следующий токен из списка предложенных 
    next_token = select_next_token(candidates)
    # select_next_token(candidates: list[float]) -> int
 
    # Прикрепляет его к списку токенов
    tokens.append(next_token)
 
    # Решаем, хотим ли мы прекратить генерацию.
    # Здесь может быть счётчик токенов, задержка, стоп-слово или что-то ещё.
    if should_stop_generating():
      break
 
  # Преобразует список токенов в строку
  completion = detokenize(tokens) # detokenize(tokens: list[int]) -> str
  return completion

Давайте реализуем все эти элементы один за другим на языке SQL.

Токенизатор

Прежде, чем текст можно будет скормить нейронке, его требуется преобразовать в список чисел. Конечно, нас это не удивляет: именно такие задачи решаются при помощи текстовых кодировок вроде Unicode. Но обычный Unicode не слишком хорошо работает с нейронными сетями.

В сущности, нейронные сети построены на обширном перемножении матриц, и вся прогностическая сила нейронных сетей заключена в коэффициентах этих матриц. Некоторые из таких матриц содержат по строке на каждое из возможных значений в «алфавите», в других предусмотрено по строке на «символ».

В этом контексте смысл терминов «алфавит» и «символ» требуется пояснить. В Unicode длина «алфавита» составляет 149186 символов (именно столько отдельных точек Unicode существует на момент подготовки этой статьи), а в качестве «символа» может выступать, например: ﷽ (да, это одиночная точка Unicode, номер 65021, она соответствует целой фразе на арабском языке, особенно важной для мусульман). Отмечу, что эту фразу можно было бы записать и обычной арабской вязью. Таким образом, одному тексту может соответствовать несколько вариантов кодировки.

Давайте разберём эту ситуацию на примере слова "PostgreSQL". Если бы мы попытались закодировать её (преобразовать в массив чисел) при помощи Unicode, то у нас получилось бы 10 чисел, которые могли бы находиться в диапазоне от 1 до 149186. Таким образом, в нашей нейронной сети требовалось бы хранить матрицу из 149186 строк и совершить ряд вычислений над 10 строками из этой матрицы. Некоторые из этих строк (соответствующие буквам латиницы) использовались бы особенно часто, и в них было бы заключено много информации. Другие символы, например, смайлик какашки и таинственные символы из мёртвых языков едва ли вообще хоть раз использовались, но и на их хранение требуется место.

Естественно, мы хотим, чтобы оба эти числа, и длина «алфавита», и количество «символов» оставались как можно меньше. В идеале «символы» нашего алфавита должны быть распределены равномерно, а ещё мы по-прежнему хотим, чтобы наша кодировка не уступала по мощности Unicode.

Интуитивно понятно, что это можно сделать, присвоив уникальные номера тем последовательностям слов, которые часто встречаются в обрабатываемых нами текстах. В Unicode вышеупомянутая религиозная арабская фраза может быть закодирована либо как один кодовый символ, либо буква за буквой. Поскольку мы выкатываем нашу собственную кодировку, точно так же мы можем поступать с теми словами и фразами, которые важны в рамках нашей модели (например, они часто встречаются в текстах).

Например, можно было бы выделить конкретные числа для строк "Post", "greSQL" и "ing". Таким образом, оба слова "PostgreSQL" и "Posting" в нашем представлении будут иметь длину по 2. Конечно же, мы стремимся закреплять отдельные кодовые символы для более конкретных последовательностей и отдельных байт. Даже натыкаясь на тарабарщину или на иноязычный текст, такую информацию всё равно удастся закодировать, хотя, на это и потребуется больше времени.

В GPT2 используется вариант алгоритма под названием кодирование диадами (Byte Pair Encoding), предназначенный специально для этой цели. Токенизатор GPT2 использует словарь из 50257 кодовых точек (в терминологии ИИ — «токенов»), которые соответствуют различным последовательностям байт в UTF-8 (плюс отдельный токен, означающий «конец текста»).

Этот словарь мы собрали путём статистического анализа, выполненного таким образом:

1. Начинаем с простой кодировки из 256 токенов: по токену за байт.

2. Берём большой корпус текстов (предпочтительно именно тот, на котором будет обучаться модель).

3. Кодируем его.

4. Вычисляем, какая пара токенов встречается чаще всего. Пусть это будет 0x20 0x74 (пробел, за которым следует строчная "t").

5. Присваиваем следующее доступное значение (257) этой паре байт.

6. Повторяем шаги 3-5, теперь обращая внимание на последовательности байт. Если последовательность байт можно закодировать сложным токеном, то используем сложный токен. При явных неоднозначностях (например, "abc" может в одном случае быть закодировано как "a" + "bc" или как "ab" + "c"), то пользуйтесь той, номер которой меньше (это означает, что она была добавлена раньше и, следовательно, встречается чаще). Это нужно делать рекурсивно, пока все последовательности, которые можно сложить в один токен, будут сложены в один токен.

7. Выполним такое «складывание» 50000 раз подряд.

Число 50000 выбрано разработчиками более или менее произвольно. В других моделях количество токенов также держится в подобном диапазоне (от 30k до 100k).

На каждой итерации данного алгоритма в словарь будет добавляться новый токен, получаемый конкатенацией двух предыдущих. В конечном итоге получим 50256 токенов. Добавляем токен с фиксированным номером, означающий «конец текста» - и всё готово.

В версии алгоритма BTE для GPT2 есть ещё один уровень кодировки: в словаре токенов эти токены отображаются на строки, а не на массивы байт. Отображение с байт на строковые символы определяется в этой функции. Тот словарь, который она производит, находится в таблице encoder.

Рассмотрим, как реализовать токенизатор на SQL.

Данный токенизатор – неотъемлемая часть GPT2, и словарь токенов можно скачать с сайта OpenAI, равно как и оставшуюся часть модели. Нам понадобится импортировать её в таблицу tokenizer. В самом конце этого поста вы найдёте ссылку на репозиторий с кодом. Этот код автоматизирует заполнение таблиц базы данных, необходимых для работы с моделью.

В рамках рекурсивного подхода CTE разбиваем слово на токены (начиная с единичных байт) и объединяем наилучшие смежные пары, пока больше материала для объединения не останется. Само объединение происходит по принципу вложенного рекурсивного CTE.

Для примера я выбрал слово «Mississippilessly». Каждая запись в наборе результатов соответствует наилучшей найденной к данному моменту паре, которую можно «сложить», а также прогресс в обработке запроса.

На каждом шаге алгоритм BPE находит пару токенов, наиболее подходящую для слияния, и объединяет их (здесь в выводе вы видите такую слитую пару и ее ранг). При помощи такой процедуры размер пространства токенов можно сократить с 150k, присущих Unicode, до 50k, а количество токенов в данном конкретном слове с 17 до 5. В обоих случаях это отличное улучшение.

Когда приходится работать с множеством слов, токенизатор сначала разбивает текст на отдельные слова при помощи этого регулярного выражения и объединяет токены в каждом слове отдельно. К сожалению, при работе с PostgreSQL свойства символов Unicode не поддерживаются на уровне регулярных выражений, поэтому мне пришлось немного отладить систему (возможно, в процессе я угробил нормальную поддержку Unicode). Вот как результат выглядит в SQL:

Странный символ Ġ соответствует пробелу.

Этот запрос токенизирует промпт и преобразует его в массив чисел. Вот промпт и готов к долгому пути сквозь слои модели.

Векторные представления

Токены - это представления единиц естественного языка (в целом, примерно 0,75 слова на токен), поэтому любая модель, претендующая на успешное автозавершение текстов, должна каким-то образом кодировать отношения между этими единицами. Даже в изоляции части речи обладают наборами ортогональных свойств.

Возьмём, к примеру, слово «subpoena» (повестка) – оказывается, в токенизаторе GPT2 на него отведён целый токен. С точки зрения английского языка – это существительное? Да, бесспорно. А глагол? Да, и глаголом может быть. А прилагательным? Уже не очень, но, в принципе, контекст придумать можно. Это канцелярит? Чёрт возьми, ещё какой. И так далее.

Все эти свойства ортогональны, то есть, не зависят друг от друга. Слово может быть официозным существительным, но не глаголом и не прилагательным. В английском возможны любые сочетания этих признаков.

Сущности с ортогональными свойствами лучше всего кодируются в виде векторных представлений. Пусть у нас будет не единственное свойство (например, номер), а много. При желании мы можем крутить ими как захотим. Например, фраза «В судебном решении, которое процитировал адвокат, фигурирует…» с высокой вероятностью продолжается каким-то существительным, которое, не менее вероятно, стилистически относится к канцеляриту. Нас совершенно не интересует, есть ли у этого слова маргинальная семантика «глагол», либо «прилагательное», либо «цветок».

В математике отображение сравнительно узких значений на более широкие пространства (например, ID токенов на векторы) называется векторным представлением. Именно этим мы здесь и занимаемся.

Как решить, какие именно свойства окажутся представлены в этих векторах? А мы не будем. Мы просто предоставим достаточно векторного пространства для каждого токена и понадеемся, что модель на этапе обучения получит достаточно информации, чтобы заполнить все эти измерения осмысленным содержимым. В GPT2 под векторы отводится 768 измерений. Заранее (и, на самом деле, даже в ретроспективе) не известно, какое свойство слова будет закодировано, например, в измерении 247. Определённо, что-то закодировано там будет, но что именно – сказать сложно.

Какие свойства каждого из токенов мы внедрим в векторное пространство? Любые, которые помогут нам спрогнозировать, каков будет следующий токен.

ID токена? Естественно. Разные токены означают разные вещи.

Позиция токена в тексте? Да, пожалуйста. «Сине-фиолетовый» и «фиолетово-синий» — не одно и то же.

Взаимные отношения токенов? Естественно! Это, пожалуй, наиважнейшая часть задачи, и блок внимания (Attention) в архитектуре трансформера как раз впервые позволил решить эту часть задачи правильно.

Токены и позиции легко поддаются векторному представлению. Допустим, есть фраза «PostgreSQL is great», о которой заранее известно, что она отображается на четыре токена: [6307, 47701, 318, 1049].

Среди прочих параметров GPT2 есть две матрицы, называющиеся WTE (векторное представление лексических токенов) и WPE (векторное представление позиций слов). Как понятно из названия, в первом хранятся векторные представления токенов, а во втором – векторные представления их позиций. Конкретные значения, которыми окажутся заполнены эти представления, набираются в результате обучения модели, в данном случае GPT2. Насколько известно, в таблицах баз данных wte и wpe есть константы. Размер

WTE равен 50257×768, а размер WPE равен 1024×768. Второе означает, что в GPT2 можно использовать промпт, состоящий не более чем из 1024 токенов. Если записать в промпт больше токенов, мы просто не сможем вытянуть для токенов сверх 1024 их позиционные представления. Это архитектурный аспект (в терминологии ИИ – «гиперпараметр») модели, устанавливаемый на этапе её проектирования, и обучением его изменить невозможно. Когда говорят о «контекстном окне» большой языковой модели, имеют в виду именно это число.

Токен 6307 стоит у нас на месте 0, токен 47701 на месте 1, токен 318 на месте 2, а токен 1049 на месте 3. Для каждого из этих токенов и их позиций у нас по два вектора: один из WTE и один из WPE. Их требуется сложить. В результате получатся четыре вектора, которые послужат вводом для следующей части алгоритма: так работает нейронная сеть прямого распространения, в которой действует механизм внимания.

Для работы с SQL мы воспользуемся pgvector, это расширение PostgreSQL.

Небольшая оговорка: код для этого поста я пишу на обычном SQL, иногда вставляю чистые SQL-функции в качестве вспомогательных элементов. В рамках этого поста осуществить такое не составит труда, равно как определить векторные операции над массивами. Это делается за счёт небольшого снижения производительности (и уже было реализовано в версии 1 и работало, пусть и медленно). С распространением ИИ и ростом влияния векторных баз данных pgvector или эквивалентный механизм определённо укоренится в ядре PostgreSQL в течение двух-трёх релизов. Я просто решил оседлать волну, которая принесёт меня в будущее.

Вот как это делается в SQL:

WITH    embeddings AS
        (
        SELECT  place, values
        FROM    UNNEST(ARRAY[6307, 47701, 318, 1049]) WITH ORDINALITY AS tokens (token, ordinality)
        CROSS JOIN LATERAL
                (
                SELECT  ordinality - 1 AS place
                ) o
        CROSS JOIN LATERAL
                (
                SELECT  wte.values + wpe.values AS values
                FROM    wte
                CROSS JOIN
                        wpe
                WHERE   wte.token = tokens.token
                        AND wpe.place = o.place
                ) embedding
        )
SELECT  place, (values::REAL[])[0:5]
FROM    embeddings

(Чтобы вывод был короче, в этом запросе показаны только первые 5 измерений для каждого вектора).

Внимание

Та часть трансформерной архитектуры, благодаря которой она действительно феерит, называется «механизм внутреннего внимания» (self-attention). Он был впервые описан в 2017 году в статье «Attention is all you need» под авторством Васмани и др. Пожалуй, это наиизвестнейшая статья об искусственном интеллекте, и с тех пор её название превратилось в болванку (клише для именования других статей).

Итак, вероятно, к настоящему моменту у нас уже есть несколько векторов, в которых закодированы определённые синтаксические и семантические свойства слов, содержащихся в нашем промпте. Нам каким-то образом нужно донести эти свойства до последнего вектора. Сейчас будет небольшой спойлер: именно в последнем векторе будет храниться представление того слова, которым продолжится фраза.

Во фразе вида a «I looked at the violet and saw that it was not the usual …» (я взглянул на лиловое пятно и заметил, что это не обычный…), на месте многоточия должно быть что-то, увиденное вами (об этом свидетельствует слово «saw»), обладающее свойством «лиловости» и при этом «необычное» (сочетаем токены «не» и «обычный», тем самым меняя знак измерения «обычность» на противоположный). Можно привести такую реалистичную аналогию: человек читает книгу на иностранном языке, о котором имеет некоторое представление, но свободно им не владеет. В таком случае человеку придётся аккуратно сплетать каждое слово со следующим, и, если он не обратит внимания на ключевую часть фразы, то всю фразу поймёт неправильно.

Чтобы обеспечить такой перенос значения от одного токена к другому, требуется разрешить векторам всех токенов влиять друг на друга. Так, возвращаясь к английскому: если мы хотим наполнить слово «it» конкретной семантикой, то какая часть семантики должна поступить от предыдущих векторов в промпте, а какая – остаться от самого слова «it»?

В данной модели эта задача решается при помощи 12 наборов матриц, именуемых Q (запрос), K (ключ) и V (значение). В каждой из них по 64 столбца. Их мы получаем из векторных представлений через 768×2304-мерное линейное преобразование c_attn, веса и смещения которого хранятся в таблицах c_attn_w и c_attn_b.

Результатом c_attn является матрица со n_token строк и 2304 столбцами (3×12×64). Она состоит из 12 Q-матриц, 12 K-матриц и 12 V-матриц, упорядоченных горизонтально именно в таком порядке.

Каждый набор, состоящий из Q, K и V, называется «головой». С их помощью выполняется шаг под названием «многоголовое условное внутреннее внимание», на котором вычисляется функция внимания.

Она вычисляется по этой формуле:

b7a3f0ee8816d3c95951491a32765034.png

где softmax – это функция нормализации весов. Она определяется так:

f63cb8d1f794504cc4a9512b4ba3ef4b.png

M - это матрица-константа, именуемая «условной маской». Она определяется так:

6663f6f6cf9689a78b9b50a827fe4b53.png

Функция Softmax обнуляет все отрицательные бесконечности.

Почему необходимо использовать маски?

В промпте из предыдущего примера было 4 токена, и модель первым делом вычисляла 4 векторных представления для 4 этих токенов. По мере дальнейшей работы модели над этими векторами будет выполнено много вычислений, но в основном они пойдут независимо и параллельно. Изменения в одном векторе не затронут другие векторы, как если бы иных векторов не существовало. Векторы влияют друг на друга только в пределах блока внутреннего внимания.

Как только модель справится с математикой, претенденты на роль следующего токена будут выбираться исключительно исходя из последнего векторного представления. Вся информация должна направляться именно к этому последнему вектору, а не прочь от него. Временные значения последнего вектора не должны влиять на временные значения предыдущих векторов, использовавшихся в ходе прямого распространения по данной модели.

Именно поэтому мы «маскируем» позднейшие векторы, чтобы они не влияли на более ранние через этот конкретный канал. В этом и заключается условность «многоголового условного внутреннего внимания».

Почему матрицы называются "запрос", "ключ" и "значение"?

Честно говоря, даже не уверен, что это хорошая аналогия. Но, тем не менее, попытаюсь объяснить, какова логика таких названий.

Как правило, в машинном обучении при вычислениях не должны использоваться циклы переменной длины или ветвление инструкций. Все задачи должны решаться компоновкой простых аналитических функций (сложение, умножение, возведение в степень, логарифмы и тригонометрия). Так обеспечивается обратное распространение для эффективной реализации которого требуются такие технологии, как автоматическое дифференцирование.

Математическая модель хранилища ключей и значений заключена в таком выражении:

de4db9304ce9fe7850fa07f4aa82a4db.png

Но это не гладкая дифференцируемая функция, и с обратным распространением она работать не будет. Чтобы формула работала, необходимо получить гладкую функцию, которая была бы близка к v, когда k близка к q, и близка к 0 в иных случаях.

Для этой цели отлично подходит Гауссово распределение («колоколообразная кривая») "bell curve"), отмасштабированная к v с ожиданием k и достаточно небольшим стандартным отклонением:

cb7ce72dab8bcafebcd14cf861b908a2.png

где σ - произвольный параметр, определяющий, насколько «остра» колоколообразная кривая.

Если взять в векторном пространстве с достаточно большим количеством измерений фиксированный вектор K и несколько векторов Q, которые случайным и равномерным образом отклоняются от K в каждом из измерений, то их скалярные произведения сложатся именно в колоколообразную кривую. Соответственно, в векторном пространстве «дифференцируемое хранилище ключей и значений» можно смоделировать при помощи выражения

673f867f6aacaf8ba018b96d5399f9e2.png

того самого, которым мы пользовались в нашей функции внимания.

Опять же, эта аналогия немного натянута. Лучше не слишком зацикливаться на концептуальной составляющей внимания, то есть, на потоке операций, хеш-таблицах и пр. Можете считать, что они просто вдохновили меня на описанный математический фокус, который я догадался протестировать – и на практике он оказался весьма хорош.

Вот что мы сделали:

1. Прежде, чем вычислять функцию внимания, мы нормализовали векторы при помощи линейного преобразования R’ = RГ1 + B1. Матрица Г1 и вектор B1называются, соответственно, «масштабирование» и «сдвиг». Это параметры, изученные моделью, которые хранятся в таблицах ln_1_g и ln_1_b

2. Мы показываем только первую голову первого слоя, используемого в этом алгоритме. После того, как умножим векторы на изученные коэффициенты из c_attn_w и c_attn_b («вес» и «смещение»), порежем полученные в результате 2304-мерные векторы. Возьмём 64-мерные векторы, начинающиеся в позициях 0, 768 и 1536. Они соответствуют векторам Q, K и V первой головы.

3. EXP в PostgreSQL плохо работает с очень малыми числами, и именно поэтому мы прибегаем к нулю, если EXP получает аргумент менее -745,13.

4. Для каждого вектора мы показываем только первые три элемента. Марицу внимания показываем полностью.

Итак, значение первого вектора копируется в вывод как есть (так мы поступаем с первым значением на каждом слое алгоритма). Это означает, что, когда модель уже обучена, результирующее векторное представление первого токена будет определяться только значением первого токена. В принципе, на этапе рекурсивного вывода, пока токены только добавляются в промпт, по сравнению с предыдущей итерацией изменится лишь самое последнее векторное представление в выводе. Именно поэтому применяется условная маска.

Заглянем немного вперёд: блок внимания – это единственное место во всём алгоритме, где токены могут влиять друг на друга на этапе прямого прохода. Поскольку на данном этапе мы не позволяем позднейшим токенам влиять на более раннее (и отключили такую возможность), все вычисления, проделанные над более ранними токенами, можно повторно использовать на разных итерациях прямого прохода по модели.

Напомню, модель при работе добавляет токены в промпт. Если исходный (токенизированный) промпт – это «Post greSQL Ġis Ġgreat», а следующий, например, будет «Post greSQL Ġis Ġgreat Ġfor», то все результаты вычислений, проделанных над первыми четырьмя токенами, можно будет повторно использовать и в новом промпте. Они никогда не изменятся, независимо от того, что ещё будет прикреплено к этому промпту.

В статье Джея Муди, которую я привёл для примера, этот аспект не задействуется (равно как и в моей статье – для простоты), но в оригинальной реализации GPT2 он задействован.

Закончив работу со всеми головами, получаем 12 матриц. Каждая из них будет по 64 столбца в ширину и по n_tokens строк в высоту. Чтобы вновь отобразить её на размерность векторных представлений (768), нам просто нужно составить эти матрицы горизонтально.

Последний этап обработки многоголового внимания связан с проецированием значений путём линейного преобразования в том же самом измерении. Соответствующие веса и смещения хранятся в таблицах c_proj_w и c_proj_b.

Ниже приведён полный код, описывающий реализацию многоголового внимания в первом слое:

Прежде чем результаты многоголового внимания будут переданы на следующий шаг, к ним нужно добавить оригинальные входные данные. Этот фокус был описан ещё в исходной статье по трансформерам. Предполагается, что он должен помочь с затухающими и взрывными градиентами.

Это распространённая проблема при обучении: иногда градиенты параметров оказываются слишком малы или слишком велики. Если менять их при очередной итерации обучения, это также очень слабо влияет на функцию потерь (поэтому модель сходится очень медленно). Бывает и обратный эффект: даже минимальное изменение отбрасывает функцию потерь слишком далеко от локального минимума, тем самым обесценивая всю работу по обучению.

Прямое распространение

Именно в этом и заключается работа глубоких нейронных сетей. Большая часть параметров модели на самом деле используется именно на этом этапе.

Здесь мы имеем дело с многослойным перцептроном, у которого три слоя (768, 3072, 768), а в качестве функции активации используем линейную единицу гауссовской ошибки (GELU):

1582eb4081148863170cf26deff796b0.png

Как показывает практика, эта функция даёт очень хорошие результаты при работе с глубокими нейронными сетями. Её можно аналитически аппроксимировать вот так:

4e7d6916854cc78e19fab9621165d0de.png

Изученные параметры линейного преобразования для связей в слое называются c_fc (768 → 3072) и c_proj (3072 → 768). Значения с первого слоя сначала нормализуются при помощи коэффициентов, содержащихся в изученном параметре ln_2. По завершении этапа прямого распространения его ввод вновь добавляется к выводу. Этот элемент также входит в самый первый вариант дизайна трансформеров. Весь этап прямого распространения выглядит так:

А вот как это делается на SQL:

Именно этот вывод получаем из первого блока GPT2.

Блоки

Операции, рассмотренные на предыдущих этапах, повторяются в каждом из слоёв (именуемых «блоками»). Блоки выстраиваются в виде конвейера, так, что вывод из предыдущего блока сразу подаётся на ввод следующему. У каждого из блоков – свой набор изученных параметров.

В SQL потребуется соединить блоки при помощи рекурсивного CTE.

Как только финальный блок выдаст значения, результат потребуется нормализовать при помощи изученного параметра ln_f.

Вот как в итоге будет выглядеть модель:

Это вывод модели.

Четвёртый вектор – это и есть фактическое представление следующего токена, предсказанного моделью. Нам просто нужно отобразить его обратно на токены.

Токены

У нас уже есть векторное представление (768-мерное), в котором, согласно модели, заключены семантика и грамматика наиболее вероятного продолжения промпта. Теперь нам нужно отобразить его обратно на токен.

Одна из первых операций, совершаемых моделью – это отображение токенов на их векторные представления. Эта операция делается при помощи матрицы wpe размером 50257×768. Той же самой матрицей нам потребуется воспользоваться, чтобы отобразить векторное представление обратно на токен.

Проблема в том, что строго обратное отображение выполнить невозможно: (вероятно) векторное представление не будет совпадать ни с одной из строк в матрице. Поэтому нам придётся найти токен, который «ближе всего» к векторному представлению.

Поскольку (как мы надеемся), в измерениях векторных представлений заключены некоторые семантические и грамматические аспекты токена, необходимо сопоставить их как можно точнее. Один из способов консолидировать «степень близости» каждого из измерений – вычислить скалярное произведение двух векторных представлений. Чем выше будет это значение, тем ближе токен к прогнозу.

Для этого умножим векторное представление на матрицу wte. В результате получим матрицу из одного столбца и 50257 строк. Каждое значение в этом результате будет произведением спрогнозированного вектора и векторного представления токена. Чем выше это число, тем вероятнее, что токен станет продолжением промпта.

Чтобы выбрать следующий токен, нужно просто преобразовать значения сходства в значения вероятности. Для этого нам пригодится старая добрая функция softmax (та самая, при помощи которой мы уже нормализовали веса внимания).

Почему стоит использовать softmax для работы с вероятностями?

Softmax – это удобное свойство аксиомы выбора Льюса. Оно таково: относительная вероятность двух вариантов не зависит от наличия прочих вероятностных вариантов. Если вариант A влвое вероятнее варианта B, то это соотношение не зависит от наличия или отсутствия других вариантов (хотя, конечно, абсолютные значения при этом могут измениться).

Вектор скалярных произведений («логит» в терминологии ИИ) содержит произвольные значения, которые могут не укладываться в какую-либо шкалу. Если балл A выше, чем балл B, то известно, что A вероятнее – а больше ничего не известно. Можно подкорректировать входные значения softmax так, как нам угодно, главное, соблюдать их порядок (более крупные значения остаются более крупными).

Распространённый подход, позволяющий этого добиться – нормализация значений путём вычитания наибольшего значения из каждого значения в множестве (так что наибольшее значение становится равным 0, а все остальные – отрицательным числам). Затем берём фиксированное количество наивысших значений (скажем, топ-5 или топ-10). Наконец, перед передачей всех значений softmax умножаем их на константу.

Количество наивысших значений, с которым мы работаем, обычно называется top_n, а множитель-константа (вернее, обратное ему число) называется «температурой» (Т). Чем выше температура, тем более гладкое распределение вероятностей у нас получится, и тем выше вероятность, что на место продолжения будет выбран не первый попавшийся токен.

Формула для расчёта вероятностей токенов

где scores — это множество из наивысших top_n баллов.

Почему этот показатель называется "температурой"

Функция softmax также называется распределение Больцмана. Она широко используется в физике. Среди прочего, на ней основана барометрическая формула, по которой рассчитывается изменение плотности воздуха в зависимости от высоты.

Как известно, тёплый воздух поднимается вверх и распределяется на сравнительно большой высоте. В горячем воздухе сравнительно высока вероятность, что молекула ль частых столкновений с другими молекулами заберётся на такую высоту, куда в ином случае бы не попала. В отличие от ситуации с более холодными температурами, плотность воздуха увеличивается на больших высотах и падает на уровне моря.

Сравните, как воздух движется при разных температурах:

Аналогично, в рассматриваемом нами примере, чем больше «температура», тем выше вероятность, что будет выбран не самый очевидный токен (разумеется, за счёт наиболее очевидных). Логический вывод становится менее предсказуемым и более «творческим».

Давайте выразим всё это на SQL. У нас был промпт «PostgreSQL is great». Вот первые 5 токенов, которые, в соответствии с этой моделью, являются наиболее вероятными продолжениями этой фразы. Показаны их вероятности при разной температуре:

Логический вывод

Вот мы и готовы перейти к реальному логическому выводу: запустить модель, выбрать токен в соответствии с полученной вероятностью, добавить токен к промпту и повторять этот процесс до тех пор, пока не будет сгенерировано достаточное количество токенов.

Как было показано выше, сама большая языковая модель является детерминированной. Это просто последовательные перемножения матриц и другие математические операции, производимые над заранее определёнными константами. Пока промпт и такие гиперпараметры как температура и топ-N остаются неизменными, вывод также остаётся неизменным.

Единственный недетерминированный процесс в данном случае – это выбор токена. В нём заложена (переменная) степень случайности. Вот почему чатботы, основанные на GPT, могут давать разные ответы на один и тот же промпт.

Воспользуемся в качестве промпта фразой «Happy New Year! I wish» и прикажем модели сгенерировать 10 новых токенов для этого промпта. Температуру установим в 2, а top_n в 5.

У меня на компьютере на этот запрос уходит 2 минуты и 44 секунды. Вот такой вывод получается:

    HOW I RECOVER MY LOST FUNDS AFTER INVESTING Exercise extreme caution when dealing with this company. They scammed me out of my money and even gained unauthorized access to my banking information, which severely impacted my financial well-being. I had initially approached them with the hope of improving my life through investment, but instead, I was deceived. This company should be thoroughly investigated and shut down to prevent further harm. Fortunately, I was able to recover my funds thanks to Mrs. Rose. Although I was initially hesitant and unsure about contacting her, I decided to take the risk and I’m so glad I did. You can reach her via telegram user name (@RoseCyberHives) and email rosecryptoinvestment11@gmail. com With the help of her skilled team of cybersecurity professionals and cryptocurrency experts, I was able to recover my lost funds quickly and with minimal stress, a sharp contrast to my previous experience. If you’ve been scammed or are in a similar situation, I highly recommend reaching out to her for assistance. via telegram user name (@RoseCyberHives) rosecryptoinvestment11@ gmail. com

    My name is Martha, and I never thought I’d be the victim of a crypto scam, but life has a way of humbling you. A few months ago, I invested a huge chunk of my savings, decades of hard-earned money into what seemed like a promising crypto platform. The slick website, glowing testimonials, and a charming advisor convinced me to transfer 15 Bitcoin, into their wallet. Days later, the platform vanished, my funds were gone, and I was left with nothing but regret. Desperate, I turned to the internet, scouring forums and posts on X for help. That’s when I stumbled across Alpha Spy Nest, a shadowy group of cyber-recovery experts specializing in crypto fraud. Their reputation was murky but promising whispers of successful recoveries and a no-nonsense approach. I reached out through their encrypted portal, half-expecting a scam. Within hours, they responded, asking for details: transaction IDs, wallet addresses, and screenshots of my interactions with the scammers. Alpha Spy Nest operated in the dark corners of the web, using a mix of blockchain forensics, social engineering, and unconventional methods to track lost crypto. They traced my Bitcoin to a series of obfuscated wallets, likely controlled by an offshore syndicate. The team deployed advanced chain-analysis tools to follow the funds, pinpointing a weak link in the scammers’ network, a poorly secured exchange account in Eastern Europe.Over weeks, Alpha Spy Nest worked tirelessly, infiltrating the scammers’ digital trails. And then i received a message, we’ve got a lead. They’d recovered 12 of my 15 Bitcoin, transferred to a secure wallet they set up for me. The rest, they said, was likely gone forever, but I was overjoyed. My savings were partially restored, and I felt a weight lift. I never met them, but they gave me back hope and a lesson, the crypto world is a jungle, but sometimes, even in the dark, there are allies.

    Hi everyone, I'm an entrepreneur, and when I learned about cryptocurrencies and how they potentially triple my income, I was excited to invest. I hope this message finds the correct audience. On the internet, I came across someone who assured me of exceptionally significant returns on my investment. I was readily persuaded by this man's seeming wisdom. I quickly discovered that this cryptocurrency was a hoax and that I was unable to withdraw my money after making a substantial investment. My business was in tatters, and I owed money.Fortunately for me, a pop-up regarding cryptocurrency recovery and cybersecurity specialists that could help me get all of my money back appeared when seeking for help on the internet. This organization, WIZARD JAMES RECOVERY, is a cyber security and cryptocurrency recovery firm that helped me get my investment money back.

    RECLAIM CRYPTO LOSS: HIRE META TECH RECOVERY PRO TO RECOVER LOST ASSET BACK. The adage "all that glitters is not gold" proved a harsh reality I recently encountered. The digital realm of cryptocurrency investments and exchange platforms is not immune to deception. My pursuit of cryptocurrency investments led me to a seemingly legitimate site, complete with convincing investor testimonials touting successful withdrawals. Unbeknownst to me, it was an elaborate scheme. I invested $210,000.00 worth of cryptocurrency across multiple wallets, as directed by the scammers. Initially, the process mirrored typical modern investments, but my withdrawal requests were met with evasiveness and silence. This represented my entire life savings, accumulated through years of dedicated work, now vanished in an instant. Refusing to accept defeat, I sought assistance from METATECH-RECOVERYPRO, which facilitated a successful recovery. Their process was remarkably efficient. They meticulously traced my lost funds back to the perpetrators, and within a short timeframe, the recovered assets were returned to my bank account. Without this exceptional recovery team, which offered support when all hope seemed lost, my situation would have been dire. To initiate your recovery, I strongly advise sending a detailed email ([email protected]) of your task, outlining your specific circumstances.

    CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.

    CRYPTO TRACING AND RECOVERY: HIRE A LEGITIMATE RECOVERY EXPERT" CONTACT RAPID DIGITAL RECOVERY

  • 12.08.25 18:44 edinavida027

    A recruiter named Emma Zhang reached out to me on LinkedIn regarding an intriguing job opportunity that piqued my interest. She presented a position for a Crypto Security Specialist with a Coinbase-certified firm. Her profile appeared legitimate, boasting over 1200 connections and numerous endorsements from industry professionals that seemed authentic. The offer was enticing: a salary of $180,000 plus bonuses, all disbursed in Bitcoin. The recruiter promptly sent me an email from a seemingly official domain , which closely resembled Coinbase's actual email addresses. It felt like an incredible opportunity. However, there was a stipulation: to qualify for the position, I needed to confirm that I possessed at least 4 BTC. This requirement struck me as peculiar but not entirely implausible, given the nature of the role. At that moment, I had sufficient BTC to meet the demand, so I decided to proceed. The HR representative directed me to a portal that closely mimicked Coinbase's official interface. It was convincing enough that I didn’t hesitate to log in and complete the necessary steps. Unfortunately, that was where everything began to unravel. I was instructed to send a verification deposit of 1 BTC to confirm my ownership. Since everything appeared legitimate, I complied without hesitation. However, the moment I transferred the BTC, an unsettling feeling washed over me. The following day, I noticed that the remaining 3 BTC in my wallet began to vanish. My heart sank as I realized something was terribly amiss. I immediately attempted to reach out to both the HR representative and the company, but my efforts were met with silence. Upon checking the LinkedIn profiles of Emma Zhang and her team, I discovered they had mysteriously vanished. I was left with nothing no job offer, no recruiter, and no Bitcoin. I turned to the internet in search of solutions. That’s when I stumbled upon RAPID DIGITAL RECOVERY, a company specializing in Bitcoin recovery. I contacted them, and they assured me they could assist in recovering my lost funds. After a tense and arduous process, they successfully retrieved my stolen BTC. The relief I felt was indescribable, and I am profoundly grateful to RAPID DIGITAL RECOVERY for their expertise and unwavering support.

    HOW I RECOVER MY LOST FUNDS AFTER INVESTING Exercise extreme caution when dealing with this company. They scammed me $800,000 out of my money and even gained unauthorized access to my banking information, which severely impacted my financial well-being. I had initially approached them with the hope of improving my life through investment, but instead, I was deceived. This company should be thoroughly investigated and shut down to prevent further harm. Fortunately, I was able to recover my funds thanks to Mrs. Rose. Although I was initially hesitant and unsure about contacting her, I decided to take the risk and I’m so glad I did. You can reach her via telegram (@RoseCyberHives) and email rosecryptorecovery@gmail. com With the help of her skilled team of cybersecurity professionals and cryptocurrency experts, I was able to recover my lost funds quickly and with minimal stress, a sharp contrast to my previous experience. If you’ve been scammed or are in a similar situation, I highly recommend reaching out to her for assistance. via telegram (@RoseCyberHives) rosecryptorecovery@gmail. com

    After my wife passed, I found myself lonely and searching for connection. I joined a senior living forum just to talk with others my age to share stories, maybe feel a little less isolated. That’s where I met a man who claimed to be helping retirees like me manage their savings with cryptocurrency. He spoke warmly and convincingly about a retirement care fund that guaranteed lifetime monthly payouts. He said it was specifically designed for people in my stage of life safe secure and backed by health organizations. He gained my trust over weeks of conversation. We spoke daily. He called me by name asked about my late wife, and remembered little details about my life. I believed he genuinely cared. Eventually, I transferred $200000 in USDT the majority of my retirement savings, into the wallet address he provided. That was the last time I heard from him. The forum profile vanished. His phone number stopped working. No response to emails. I was stunned. I couldn’t believe I had been tricked. I didn’t know who to turn to. I felt ashamed and foolish. At my age recovering from a financial loss like this is nearly impossible.My relative stepped in. They searched online for solutions and found TRUST GEEKS HACK EXPERT. I was skeptical at first but they insisted we give them a chance. From the moment we contacted them they treated me with respect patience and genuine concern. Their team didn’t speak in technical riddles. They explained every step. They used blockchain analysis tools to trace the movement of my funds through several addresses.It turned out the wallet was linked to a scam platform. TRUST GEEKS HACK EXPERT worked directly with the USDT issuer and coordinated with relevant platforms to freeze the funds before they were fully laundered.In just two weeks they managed to recover $155000 in USDT.The money helped yes but it was more than that. I no longer felt powerless. I had been taken advantage of but I wasn’t alone in the fight. Thanks to TRUST GEEKS HACK EXPERT I got back not only a large part of my savings but also peace of mind a sense of dignity and hope for the future.

    My Wild Ride: How a Wizard Hilton Cyber Tech Helped Me Recover Lost Bitcoin of 103,000 It all started when I had the misfortune of misplacing the digital wallet containing my substantial cryptocurrency holdings - a staggering 103,000 bitcoins. I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future. This harrowing experience taught me the invaluable lesson of never taking the security of my cryptocurrency holdings for granted, and the importance of always maintaining the utmost diligence when it comes to protecting one's digital wealth.

    Losing nearly 500,000 USDT to hackers was one of the most devastating experience of my life. I felt powerless as my hard-earned assets vanished into anonymous blockchain transactions until I found Agent Jasmine Lopez. Her deep expertise, tireless effort, and unwavering focus gave me hope and delivered results. She traced complex transactions, pursued every lead, and recovered a large portion of my stolen funds something I never thought possible. If you’ve lost digital assets, don’t give up. Contact Recoveryfundprovider@gmail. com WhatsApp at +{44 736-644-5035}. She turned my nightmare into a recovery story, and she could do the same for you.

    I’m a California resident who was contacted by someone named “Lin” on WhatsApp. Our conversation eventually turned to cryptocurrency investments. Lin introduced me to a trading platform called CBOTBIT (https://cbotbit.com), walked me through setting up an account, and guided me on transferring funds. Under Lin’s direction, I began trading and was led to believe that my account was growing significantly. However, when I attempted to withdraw my funds, I was unable to do so — and shortly after, the website went offline entirely. I had invested over $340,000 in Bitcoin, planning to use it for my retirement. The experience was devastating, and I was at a loss for what to do next. Eventually, I came across [email protected] and decided to reach out. I followed their instructions, and within a few days, I was able to recover my original investment. I'm incredibly relieved and grateful for their assistance, and I recommend contacting them if you’re in a similar situation and need help recovering lost funds.

    I can honestly say losing my bitcoin savings was one of the darkest moments of my life. I had put everything I could into that investment, believing it would secure my future, only to wake up one day and realize the platform had vanished with all my funds. The feeling was indescribable, fear, shame, and helplessness all at once. I thought I’d never see that money again. Then I came across Alpha Spy Nest. At first, I was hesitant, I had already been deceived once, and the thought of trusting anyone else terrified me. But something about their professionalism and the way they patiently explained things gave me a little hope. For the first time in weeks, I felt like I wasn’t completely alone in the fight. They listened to my story without judgment, broke down the technical side in a way I could understand, and reassured me that there was still a chance. Watching them work was incredible. They traced every transaction, uncovered where my bitcoin had been moved, and kept me updated through every stage. It felt like they cared as much about my recovery as I did. The day they told me they had successfully recovered my lost savings, I actually cried. Seeing those funds back in my wallet felt unreal, it was like a huge weight had been lifted off my shoulders. Beyond just recovering my bitcoin, Alpha Spy Nest gave me back my peace of mind and restored a trust I thought I had lost forever. I’m forever grateful to them. If I hadn’t found Alpha Spy Nest, I’d still be stuck in regret and despair. Instead, I now share my story as proof that recovery is possible.

    You are not alone if you have had your bitcoins taken from your wallet or if you invested in an initial coin offering (ICO) that was a scam. I experienced the same thing. I first lost $173,000 to a fraudulent investment scam company in less than five months. I was able to get all of my money in five days thanks to a hacker my friend recommended. In order to raise awareness about these cryptocurrency criminals and do my part to minimize the number of victims, I'm speaking out. To report a victim, simply send an email to [email protected].

I had amassed this sizable fortune over the years through strategic investments and careful trading, but in a moment of carelessness, the private keys to my digital wallet had vanished. Panic set in as I grappled with the gravity of my situation - those bitcoins, worth millions at the time, were effectively lost to the ether, inaccessible and seemingly unrecoverable. Just when I had resigned myself to the devastating financial blow, a chance encounter with a self-proclaimed "digital wizard" Wizard Hilton Cyber Tech presented a glimmer of hope. This enigmatic individual, who operated in the shadowy corners of the crypto underworld, claimed to possess the arcane knowledge and skills necessary to retrieve my lost digital wealth. Intrigued and desperate, I put my skepticism aside and entrusted this mysterious wizard with the task. What followed was a wild, suspenseful journey into the depths of blockchain technology and cryptography, as the wizard navigated complex algorithms, exploited vulnerabilities, and pieced together the puzzle of my missing private keys. After days of intense effort, Wizard Hilton Cyber Tech emerged triumphant, having successfully recovered the entirety of my 103,000 bitcoin stash. The sheer relief and elation I felt in that moment was indescribable, as I regained access to my small digital fortune and was able to secure my financial future.

    E.M.A.I.L. [email protected] W.h.a.t.s.A.p.p. +1(561)(726)(3697) It all began with an Instagram advertisement. A man presented himself as a cryptocurrency investment coach, showcasing a luxurious lifestyle and screenshots of substantial profits. He claimed his trading algorithm could double any investment in a week. Curious, I decided to reach out to him. He said the minimum investment was $50,000 and sent me a link to a platform that looked legitimate. At first, everything seemed promising. My balance increased steadily, charts showed growth, and I felt excited. When I tried to withdraw the money, the system blocked the transaction and demanded a release fee of $15,000. I paid it, but my account was soon marked under review, and the coach stopped responding. I realised I had been scammed. Desperate, I turned to Techy Force Cyber Retrieval. From the first consultation, they carefully reviewed my case and assured me the funds could be traced. They explained how they would track the wallet addresses and follow the path of the stolen money. Their clear guidance made me feel confident. Over the next few weeks, Techy Force Cyber Retrieval kept me updated on every step. They traced the transactions. Their persistence and expertise were obvious, and I could see real progress. Even when the process felt slow, Techy Force Cyber Retrieval maintained clear communication. They explained each action and why it mattered. Their careful attention made the ordeal manageable and reassuring. A month later, thanks to Techy Force Cyber Retrieval, I was able to recover 80% of my money and have it safely returned to my bank account. Relief and gratitude overwhelmed me. What started as a tempting opportunity had turned into a stressful ordeal, but Techy Force Cyber Retrieval transformed it into a successful resolution.

    A hacker skillfully impersonated one of our clients’ trusted suppliers and manipulated their finance department into transferring $180,000 worth of Bitcoin. The request appeared authentic, reinforced by falsified documents and meticulously crafted communication that mirrored the supplier’s established style. By the time the company uncovered the deception, the funds had already been funneled through numerous digital wallets. When they appealed to their bank for assistance, they were told recovery was impossible since cryptocurrency transactions are irreversible. The company suddenly faced the prospect of financial ruin. Confronted with this devastating loss, the client sought a specialized solution and turned to Techy Force Cyber Retrieval. From the initial consultation, our team demonstrated that hope remained.
