Language Models
LLM 은 어떻게 동작하는가?
먼저, 이건 지도학습 기반으로 학습된다
.
Input 과 Output 인 데이터를 기반으로 학습되서 다음에 올 단어를 예측하는 시스템임.
Q) 이때 Input 과 Output 은 어떻게 되는거?
완전한 문장인 "My favorite food is a bagel with cream cheese and lox." 가 있다고 한다면, 이렇게 트레이닝 셋이 구성됨.
- 1) Training set
- Input: My favorite food is a
- Output: bagel
- 2) Training set
- Input: My favorite food is a bagel
- Output: with
- 3) Training set
- Input: My favorite food is a bagel with
- Output: cream
이런식으로 문장을 엄청 많이 만들어서 다음 단어, 문장이 뭐가 올 지 학습하는거임.
LLM 은 크게 두 종류가 있음
Base LLM:
- Base LLM은 대량의 텍스트 데이터로 훈련된 모델임.
- 기본 LLM은 특정 작업이나 지시어에 대해 최적화되지 않은 상태로 배포됨. 즉, 일반적인 지식과 언어 처리 능력을 바탕으로 다양한 요청에 대응할 수 있지만, 특정 지시어에 따른 성능 최적화는 이루어지지 않음.
- 그래서 what is capital of france? 라고 물으면 Paris 라고 대답하는게 아니라 what is popularity of france? 라고도 대답하기도 함.
Instruction Tuned LLM:
- 기본 LLM에 비해 한 단계 더 발전된 형태로, 특정 지시어(instruction)에 따른 성능을 향상시키기 위해 추가적인 튜닝 과정을 거친 모델임. 이 과정에서 모델은 특정 지시어나 요구 사항을 더 잘 이해하고 처리할 수 있도록 최적화됨. 그래서 사용자의 명령이나 요청을 더 정확히 파악하고, 그에 맞는 출력을 제공하는 데 특화되어 있.
- Instruction Tuned LLM 은 BaseLLM 에다가 RLHF 방법같은 걸 써서 파인튜닝 한거임.
Q) RLHF (Reinforcement Learning from Human Feedback) 이 뭔데?
인간의 피드백을 기반으로 하는 강화 학습 접근 방식으로, 모델이 특정 작업을 수행한 후 받는 피드백(보상 또는 벌점)을 통해 성능을 개선하는 방식임.
LLM Details: ChatGPT 는 "Lollipop" 이라는 문자열을 뒤집으라는 명령을 제대로 처리할 수 없는가?
LLM 은 Word 단위로 예측하는게 아니라 Token 단위로 예측하기 때문이다.
그러니까 “Prompting” 이라는 문자열은 "prom", "pt", "ing" 라는 토큰으로 분리된다. 이렇게 분리하는게 더 효율적이기 떄문이라고 함.
여기서 "토큰"이란 모델이 처리하는 정보의 기본 단위로, 단어, 구두점, 공백, 또는 서브워드(subword) 등이 될 수 있음.
이렇게 토큰 단위로 예측하니까 제대로 문자열을 뒤집지 못함.
영어 입력의 경우에는 기본적으로 하나의 토큰은 4개의 알파벳 조합으로 이뤄지거나, 3/4 word 로 구성됨.
Q) 토큰화가 왜 더 효율적인데?
- 모든 가능한 단어를 포함하는 어휘를 만들려면 엄청난 크기가 필요하기 때문. 특히 오타, 전문 용어, 신조어 등을 고려하면 어휘의 크기는 기하급수적으로 증가할 수 있다.
Q) 토큰화는 어떻게 동작하는데?
토큰화는 크게 두 가지가 있음:
- 단어 기반 토큰화(Word-based Tokenization): 가장 기본적인 형태로, 텍스트를 공백이나 구두점 등을 기준으로 단어 단위로 분리함. 이 방식은 간단하고 직관적이지만, 어휘의 크기가 매우 커질 수 있고, 희귀 단어나 신조어 처리에 어려움이 있음.
- 서브워드 토큰화(Subword Tokenization): 더 고급 방식으로, 단어를 더 작은 의미 단위로 분리함. 이는 희귀 단어 처리와 어휘 크기를 줄이는 데 도움이 됨. BPE(Byte Pair Encoding), WordPiece, SentencePiece 등이 이에 해당함.
Q) 그러면 문자열을 뒤집으려면 어떻게 해야하는데?
lollipop 이라는 단어를 l-o-l-l-i-p-o-p 처럼 표현하면 됨. 이러면 문자열을 완전히 뒤집을 수 있음. 각 알파벳마다 토큰화가 되기 때문.
이렇게 되는 이유는 구분점을 제시해주면 모델이 이를 구분해준다. 일반적인 문자 표현이 아니니까. 독립적으로 분리해서 보는거지.
GPT3.5 모델에서 4000 토큰으로 제한되어 있음.
이는 모델이 한 번에 처리할 수 있는 입력과 출력의 총 합이 4000 토큰을 넘지 않도록 제한된다는 의미임.
그러니까 모델이 한 번의 처리(인퍼런스)에서 다룰 수 있는 최대 길이를 의미함. 예를 들어, 사용자의 질문이 500 토큰이고, 모델이 생성할 수 있는 응답의 최대 길이도 이론적으로 3500 토큰이 될 수 있음.
이렇기 때문에 긴 문서의 경우에는 한번에 처리하기가 어려울 수 있음.

Moderation
두 가지 내용을 다룸:
- OpenAI Moderation API 를 사용하는 법
- Prompt Injection 을 막는 방법
- OpenAI의 Moderation API는 텍스트 또는 이미지 콘텐츠를 검토하여 부적절한 내용을 식별하고 필터링하는 도구임
- 이 API는 다양한 유형의 부적절한 내용을 감지할 수 있으며, 특히 커뮤니티 가이드라인이나 콘텐츠 정책을 위반하는 내용을 식별하는 데 유용함.

Prompt Injection 을 막는 방법은 2가지가 있음:
- delimiter 를 사용해서 User 의 Input 을 명확하게 구별하는 것. 그래서 악의적인 사용자가 Prompt Injection 을 한다고 하더라도 이것또한 메시지로 구분될거임.
- 추가적인 Prompt 를 사용해서 유저가 프롬포트 인젝션을 하고 있는지 검출하는 것

Chain of Through Reasoning
프롬포트를 작성할 떄 명시적인 Step 을 표기하고 이 순서대로 처리해달라고 요청하는 방법을 말한다.
이 방식으로 프롬포트를 작성하면 모델이 복잡한 문제를 더 효과적으로 해결한다고 함.
모델이 문제 해결 과정에서 중간 단계를 자세히 설명하도록 하여, 최종 결정에 이르는 논리적 경로를 명확히 밝히는데 도움을 줌.

Step 3:{delimiter} If the message contains products \
in the list above, list any assumptions that the \
user is making in their \
message e.g. that Laptop X is bigger than \
Laptop Y, or that Laptop Z has a 2 year warranty.
Step 4:{delimiter}: If the user made any assumptions, \
figure out whether the assumption is true based on your \
product information.
Step 5:{delimiter}: First, politely correct the \
customer's incorrect assumptions if applicable. \
Only mention or reference products in the list of \
5 available products, as these are the only 5 \
products that the store sells. \
Answer the customer in a friendly tone.
Use the following format:
Step 1:{delimiter} <step 1 reasoning>
Step 2:{delimiter} <step 2 reasoning>
Step 3:{delimiter} <step 3 reasoning>
Step 4:{delimiter} <step 4 reasoning>
Response to user:{delimiter} <response to customer>

Chaining Prompts
하나의 작업을 완료하기 위해서 여러번의 Prompt 를 입력해서 답변을 얻는 것.
Q) Chain of Through Reasoning 방식으로 하면 되는거 아니야?
이 방식은 Chain of Through Reasoning 보다 복잡한 작업을 처리할 때 유용함.
비유하자면 동시에 모든 요리를 하는 것 VS 단계별로 나눠서 하나씩 요리를 해서 완성하는 것 이 차이임.

Q) 유스케이스?

Output 을 평가하는 방법
크게 두 가지 방법이 있음:
- Rubric (평가 척도) 을 작성해서 LLM 에게 평가를 요청하는 방법
- LLM 이 생성한 Output 을 전문가가 작성한 응답과 비교하는 것.
이 두 가지 방법 모두 LLM 에게 비교하도록 요청해서 Ouput 을 평가할 수 있다.
그리고 이 방법들은 여러개의 LLM 을 쓰는 앙상블을 이용하도록 하면 더 정확하게 평가할 수 있을거임.
