Оценка LLM с большим окном контекста

Всем привет!

Мы в команде фундаментальных исследований MTS AI занимаемся исследованиями в области обработки естественного языка и компьютерного зрения, а также строим свои фундаментальные языковые модели. Недавно у нас получилось достичь уровня gpt-4 на собственном ограниченном датасете большого контекста. Расскажем, как нам это удалось.

С быстрым развитием в области обработки естественного языка, спектр решаемых большими языковыми моделями задач стал очень широк. Пользуясь моделью вроде gpt-4o, можно перевести текст с одного языка на другой, сочинить смешной стишок, решить задачку по физике или математике. На большинство таких запросов модели научились неплохо отвечать, при этом качество генераций растет с каждым днем. Однако какими бы качественными современные модели бы ни были, у каждой из них есть свои ограничения и проблемы, которые исследователи пытаются решать.

Галлюцинации в генерациях, этические нарушения, орфографические ошибки или ошибки в арифметике – немаловажные проблемы, с которыми сталкиваются при разработке больших языковых моделей. Помимо непосредственного улучшения качества генераций моделей, очень важно уметь их правильно оценивать, при этом способ оценки зависит от типа задачи.

Одна из задач связана со способностью модели запоминать контекст и не терять важную информацию, необходимую для формирования корректного ответа. В данной статье мы поговорим про особенности обучения и оценки моделей с большим окном контекста. Такие модели полезны как для ведения консистентного диалога с пользователем, так и для задач анализа документов, извлечения информации и т.д.

Помимо стандартных инструкционных моделей, наша команда в MTS AI разрабатывает LLM с длинным окном контекста – наши последние такие модели мы назвали Cotype Plus 16k и Cotype Plus 32k. Для обучения мы собрали датасет, состоящий из длинных документов и инструкций к ним, на которых впоследствии обучили наши базовые модели. Основная трудность в обучении таких моделей заключается в вычислительных затратах - механизм внимания (self-attention) имеет квадратичную сложность, и, например, обучение модели на контексте 8192 требует в 16 раз больше ресурсов чем для контекста 2048.

Существует ряд способов адаптации моделей для работы с длинным контекстом. Как правило это:

  1. модификации в архитектуре трансформера;

  2. различные способы построения и интерполяции позиционных эмбеддингов;

  3. модификации окна контекста;

  4. изменения в пайплайне обучения, специальные функции потерь.

Для обучения и оценки наших моделей мы используем методы из первых двух направлений, поэтому в данной статье мы затронем только их.

Эффективные механизмы внимания

Разберем, как решить основную проблему механизма внимания при работе с большим контекстом – квадратичную сложность при его вычислении. Больших затрат на вычисления можно избежать, используя модификации механизма внимания – это могут быть его локальные или разреженные вариации. Например, COLT5 [1] имеет в архитектуре две ветви: с обычным механизмом внимания и его легковесными вариациями, LongNet [2] использует dilated attention, а LongT5 [3] предлагает временное глобальное внимание (TGlobal), применяя механизм внимания к локальным и глобальным токенам (усреднение токенов в окне).

Такие методы, как правило, требуют дополнительного обучения модели.

LongLoRA [4]. Схематичное представление механизма Shifted sparse attention; при обучении помимо LoRA размораживаются слои эмбеддингов и нормализации.
LongLoRA [4]. Схематичное представление механизма Shifted sparse attention; при обучении помимо LoRA размораживаются слои эмбеддингов и нормализации.

Для обучения наших моделей мы использовали LongLoRA. Данный фреймворк представлен в статье “Efficient fine-tuning of long-context large language models” [4], где авторы предлагают использовать shifted sparse attention - модификацию стандартного self-attention. Этот метод предполагает что контекст делится на несколько групп, для каждой из которых внимание считается отдельно. Каждый attention head распадается на две части, и в одной из них токены смещаются, что позволяет информации передаваться из одной группы в другую, при этом значительно сократить количество вычислений. При этом во время инференса используется dense attention, что позволяет модели достигать такого же качества генераций, как и после full-attention файнтюнинга.

Позиционная интерполяция

Другой ряд методов – адаптирующих позиционные эмбеддинги – позволяет запускать на длинных задачах модели, обученные на коротких инструкциях.Такие RoPE Scaling подходы можно применить для увеличения длины контекста модели либо во время инференса без необходимости дополнительного дообучения (либо с коротким SFT этапом).

Сам RoPE (Rotary Position Embedding), впервые описанный в “Enhanced transformer with rotary position embedding” [5], очень прост: attention score между двумя токенами, показывающий насколько много “внимания” передается от одного токена к другому, должен зависеть только от относительного расстояния между ними. Таким образом, функция скора зависит только от векторных представлений двух токенов и относительного расстояния между ними.

f_q (x_m,m)^Tf_k(x_n,n) = g(x_m,x_n, m-n)

Благодаря относительной природе таких позиционных эмбеддингов, их можно скалировать, выходя за пределы изначального максимального контекста. В [6] предлагают модифицировать функцию, линейно «втиснув» новую последовательность в исходное контекстное окно.

В NTK-aware интерполяции предлагают вместо того чтобы масштабировать частоты каждого измерения RoPE на коэффициент 1/s, распределять их интерполяцию по нескольким измерениям, масштабируя высокие частоты меньше, а низкие частоты больше. Есть и другие, более сложные, способы скейлинга – YaRN [7], динамический скейлинг; однако для наших моделей мы решили использовать простой линейный скейлинг.

Наша модель Cotype Pro 16k изначально была обучена на контекст 8k, однако поскольку она имеет в архитектуре RoPE, мы смогли из коробки увеличить контекст в два раза.

Оценка long-context моделей

Для оценки наших моделей мы составили два бенчмарка (на контексты 16к и 32к) по 50 вопросов, в которых собрали инструкции с длинным контекстом, из которого модель впоследствии должна достать необходимую информацию. Пример вопроса с ответами нашей модели и бейзлайнов приведен ниже.

Алисийские поля, Елисейские поля

В греческой мифологии праведные души после смерти отправляются на Елисейские поля. Это место представлялось древними греками как идиллический и блаженный рай, где души находят счастье и покой. Елисейские поля были местом для тех, кто прожил жизнь по высшим моральным стандартам или совершил выдающиеся дела.

В греческой мифологии праведные души после смерти попадали на Елисейские поля.

Первая запись Питера Андре в десятке лучших была "Mysterious Girl" в 1996 году.

Праведные души в греческой мифологии отправляются на Елисейские поля.

Под какую бы задачу ни обучалась модель, часто встает вопрос - как именно ее оценивать? В зависимости от типа задачи могут использоваться или автоматические метрики, или мануальная оценка экспертами. В бенчмарке LongBench, например, для оценки качества англоязычных моделей на длинном контексте используют статистические метрики ROUGE-L и F1. Однако использование таких метрик подходит только для определенного класса вопросов, поскольку они не учитывают синонимичность ответов и их смысловую подоплёку в целом. Чтобы с этим бороться, для оценки больших языковых моделей прибегают к помощи человека – например, при сравнении нескольких языковых моделей часто используют side-by-side метод, когда эксперт сравнивает два ответа и говорит, чей лучше. Такой метод оценки считается очень качественным, но дорогим и долгим.

Схематичное представление работы модели для получения оценки e5m-score.Для оценки наших моделей мы решили использовать эмбеддинг-модель e5-mistral. Для получения численного значения, показывающего соответствие сгенерированного ответа “ground-truth” ответу, мы прогоняем их через e5-mistral и получаем два эмбеддинга. При перемножении двух векторных представлений мы получаем оценку их “похожести” - значения от 0 до 1, которые затем можно усреднить, пройдясь по всем вопросам из бенчмарка. Такую метрику будем называть e5m-score.

Для выбора метода оценки моделей с большим окном контекста мы провели небольшой эксперимент. Мы сравнили метрики для вычисления “похожести” пар предложений, посчитав корреляцию с распределением оценок от команды экспертов.

Команда экспертов давала каждому ответу модели тернарную оценку - 0, если ответ плохой и не похож на ground truth; 0.5 - ответ неплохой, но в чем то не соответствует ground truth; 1 - ответ хороший и соответствует ground truth. Затем оценки для каждого вопроса усреднялись по всем экспертам.

Среди представленных методов есть:

  1. описанный ранее e5m-score

  2. sbert

  3. bertscore

  4. метрика gpt4 - просим численно (от 0 до 1) оценить насколько похож ответ модели на ground-truth

  5. MIS - mutual implication score

Метод оценки моделью e5 выигрывает остальные методы, показывая корреляцию 0.8952 по Пирсону с экспертной оценкой (EV).

Используя описанный ранее подход, мы сперва обучили модели Cotype Plus 16k и Cotype Plus 32k с помощью LongLoRA. Данные модели показали себя хорошо на наших бенчмарках, держась на уровне с gpt-3.5-turbo, однако не догоняя gpt-4 (у модели заявлен контекст 64k токенов). Однако применив RoPE Scaling на одной из наших последних наработок – Cotype Pro 8k – нам удалось достичь уровня gpt-4, и даже обогнать ее.

Мы пока не можем выложить приведенные в статье данные и бенчмарки в открытый доступ, однако наши коллеги делятся новым качественным датасетом MTS-AI-SearchSkill/MTSBerquad для задачи генеративного QA!

    "In the crypto world, this is great news I want to share. Last year, I fell victim to a scam disguised as a safe investment option. I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet. What once felt impossible became a reality thanks to their support. If you have lost Bitcoin through scams, hacking, failed withdrawals, or similar challenges, don’t lose hope.

    Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

    God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

    Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

    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.
