Можно ли научить чат-бота всегда говорить правду

Привет, Хабр, меня зовут Ксения Плесовских и я развиваю генеративный ИИ в компании lad, разрабатывая чат-боты для бизнеса на основе LLM. В процессе работы над точностью ответов чат-бота, проверкой фактов и устранением галлюцинаций от LLM, мне довелось проанализировать и опробовать разные подходы к этой проблеме, чем сегодня и хочу с вами поделиться. Поскольку объем материала получился достаточно большой, на несколько публикаций, в этой части расскажу лишь о подходе самокритики.

О том, что такое RAG (Retrieval Augmented Generation) и как он работает написано уже немало статей, поэтому лишь кратко напомню, что это - механизм, который позволяет языковой модели получать информацию о тех знаниях, которые не были вложены в нее на этапе обучения и благодаря ему мы имеем возможность без дообучения модели использовать ее в сочетании с собственной базой знаний.

Хотя RAG-боты интуитивно понятны, они сталкиваются с определенными практическими проблемами. Например, мы просим модель сообщить о том, кто в нашей компании отвечает за выдачу справок в бухгалтерии, в базе знаний этой информации нет, но модель поиска все равно пытается нам ее предоставить, называя имя и контактные данные несуществующего сотрудника. Сгенерированный ответ будет ошибочным и неинформативным, особенно для неанглоязычных запросов, в которые гораздо чаще попадает контент, изначально не участвовавший в их обучении. Кроме того, при большом объеме запросов для платных LLM, например, ChatGPT, стоимость использования может привести к значительным затратам .

Для обеспечения длительного диалога с RAG необходимо сохранять историю общения и передавать ее в LLM при каждом запросе, но это может привести к падению точности или галлюцинациям поскольку у LLM возникает дополнительная задача по выбору актуальной информации из большого контекста.

Для борьбы с этими проблемами уже придумано несколько методов, об одном из которых пойдет речь ниже.

SELF-RAG - гибкое обращение к базе знаний

В качестве одного из решений обозначенных проблем исследователи из Вашингтонского университета, Института искусственного интеллекта Аллена и IBM Research AI представили структуру под названием Self-Reflective Retrival-Augmented Generation (SELF-RAG) [1]. Эта структура направлена на улучшение LLM за счет динамического получения соответствующей информации и анализа ее поколений, что приводит к повышению качества, фактологии и производительности.

В отличие от традиционных подходов, Self-RAG гарантирует, что информация, включенная в промпт модели, необходима и актуальна, тем самым улучшая качество генерируемых ответов. С помощью токенов саморефлексии, модель может контролировать и оценивать свои собственные результаты, что приводит к более точным и качественным ответам. В основе SELF-RAG лежит идея, что модели могут проверить свои собственные результаты повторным запросом с другим промптом.

Процесс саморефлексии отвечает на 2 вопроса: 1. необходимо ли в данной ситуации применение ретривера, если нет, то последующего обращения к RAG не произойдет. 2. действительно ли полученная ретривером информация релевантна промпту. В результате внешние знания добавляются к промпту только тогда, когда модель определяет, что это действительно необходимо. Для этого она возвращает специальный токен ретривера.

В дополнение к токену ретривера есть три токена критики.

Токены SELF-RAG
Токены SELF-RAG

  1. IsRel показывает, соответствует ли ответ данному вопросу и контексту.

  2. IsSup - обоснован ли ответ информацией в контексте.

  3. IsUse - насколько полезен ответ, оценивается от 1 до 5.

IsRel генерируется во всех случаях, когда пришел токен ретривера. Если модель посчитала информацию релевантной, то проверяется isSup, и если ответ снова да, то isUse присвоит ему высокую оценку.

В случаях, когда ретривер не требуется, модель генерирует только isUse.

Дополнительным положительным эффектом метода является возможность проверки фактов, т.к мы располагаем сведениями о том, обращалась ли модель к базе знаний и какой именно фрагмент данных был взят в основу ее ответа.

Почему и этого может быть недостаточно

Подход с SELF-RAG выглядит достаточно разумным, но вызывает вопрос. а не станут ли сами токены еще одной галлюцинацией модели? Можем ли мы быть уверены в том, что модель способна раскритиковать собственное решение?

В поисках ответа на вопрос, способна ли LLM к самокритике группа исследователей [2] решила проверить это на задаче раскраски графа. Результаты критики от LLM сравнивались с результатами внешнего верификатора.

В эксперименте генератор получал экземпляр данных DIMACS (графовый формат данных) и создавал промпт на естественном языке, переводя каждое ребро графа в предложение, а затем включая все это в общий набор инструкций. Исследователи намеренно свели к минимуму различия между промптами, чтобы уменьшить потерю информации в LLM.

Схема эксперимента показана рисунке ниже. Красные ромбы указывают на последовательность действий: планарный граф сначала передается в GPT-4, действующий как генератор (1), который возвращает предложенную раскраску (2). GPT-4 используется в качестве средства проверки правильности раскраски. Если это не так, GPT-4 предоставляет обратную связь вместе с предыдущей историей через обратный промпт (т.е. промпт с обратной связью (3), которая будет использоваться в запросе следующего шага (4)). Каждая новая окраска будет оцениваться GPT-4, выступающим в качестве проверяющего. Если GPT-4 определяет, что раскраска правильная или прошло 15 итераций, он утверждает окончательный ответ, где он затем сравнивается с надежным верификатором.

В режиме проверки LLM получала промпт другого типа. Помимо стандартных инструкций, он содержал только описание графа и предлагаемую раскраску. Его задача была — проверить правильность, оптимальность и то, что каждой вершине присвоено значение. Если раскраска неправильная, она должна быть проявиться набором противоречивых ребер.

Для валидации результата был создан гарантированно правильный программный верификатор. В проверке участвовали три различных типа обратного промпта. В первом случае верификатор просто просил LLM повторить попытку, если раскраска неверна. Во втором случае верификатор выдавал обратный промпт, показывающий первое нарушенное ограничение в текущей раскраске-кандидате, а в третьем - показывал все нарушенные ограничения раскраски.

Эксперимент показал, что предложенные стратегии действительно приводят к небольшому улучшению точности – с 16% до почти 40%, причем стратегия «попробуй еще раз» оказалась почти так же эффективна, как и содержательный обратный промпт. Но в момент, когда критика шла непосредственно от LLM, только 4 из 100 экспериментов были оценены негативно, и ни один из них не был оценен правильно.

К похожему выводу пришли и авторы [3], исследуя задачи планирования на языке PDDL.

Система планирования LLM+LLM состояла из генератора LLM и верификатора LLM. Генератор LLM создавал план-кандидат, а верификатор LLM определял его правильность. Если план оказывался неправильным, верификатор предоставлял обратную связь с подробным описанием причин его неудачи. Эта обратная связь приводила к созданию нового плана-кандидата. Система прекращала генерацию либо тогда, когда верификатор LLM утверждал план-кандидат как действительный, либо когда количество попыток превышало установленный порог в 15 итераций.

Основное различие между первым и вторым подходом к проверке заключалось в типе используемого верификатора.

Архитектура второго эксперимента

Из 100 PDDL планов верификатор LLM выдал 54 истинных положительных результата и 38 ложных, т.е посчитал планы фактически недействительными.

Так стоит применять SELF-RAG или нет?

Проведенные эксперименты в итоге показали, что по сравнению с заменой проверки на основе LLM внешним верификатором, подход на основе LLM страдает от ложных срабатываний и полученные решения становятся менее надежными

Кроме того, после тестирования нескольких различных уровней детализации обратного промпта, предоставляемого LLM при пересмотре его решения, выяснилось что нет почти никакой корреляции между объемом информации, предоставленной LLM, и точностью конечного результата

Общий вывод, который можно сделать из анализа, такой, что метод способен найти себя лишь в ограниченном круге задач. Поскольку для самокритики используется LLM, то очевидно, что хорошо справляться с критикой она сможет только на тех задачах, которые и без критики выполняет весьма уверенно, т.е. в случае, когда запрос и критика выполняются одной LLM, эта критика будет способна скорректировать случайные ошибки.

Более интересным выглядит сценарий, когда действия производит слабая модель, оптимизированная по ресурсам и обладающая худшим качеством, а критику осуществляет более сильная LLM. Этот подход дает возможность сэкономить на ресурсах там, где задача может быть выполнена с меньшими требованиями, когда основной объем токенов приходится на более дешевую LLM, а более сильная и дорогая в использовании модель получает лишь ответ первой модели для его оценки.

В случаях же, когда от модели требуется искать сложные причинно-следственные связи, или генерировать код без возможности его запуска, высока вероятность, что, и действие, и критика одинаково приведут к галлюцинациям и тут на помощь приходит другой подход, о котором мы поговорим далее во второй части публикации.

    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.

    "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.
