RAG

檢索增強生成 - Retrieval Augmented Generation

RAG 主要用來解決大型語言模型（LLM）實際應用時的兩大侷限：幻覺/錯覺（hallucination）與資料時限。RAG 結合「資訊檢索（retrieval）」和「生成（generation）」：在文字生成之前，先從資料庫中檢索相關的資料放入上下文，以確保 LLM 可依照正確的最新資訊生成結果。

Fine-Tune

模型微調工作流程

  1. 準備資料集(訓練資料)
  2. 準備基礎模型
  3. 匯入資料集
  4. 開始微調作業 (Fine-Tune)
  5. 評估新模型損失曲線
  6. 以新模型做實際推論

準備資料集

開始微調模型之前，您必須先建立用來微調模型的資料集。為獲得最佳效能，資料集內的範例必須具有高品質、多元且代表真實輸入和輸出的要素。

格式

資料集中包含的範例應符合您預期的實際工作環境流量。如果您的資料集含有特定格式、關鍵字、操作說明或資訊，則實際工作環境資料的格式應相同，並含有相同的指示。 例如，如果資料集中的範例包含 "question:" 和 "context:"，則實際工作環境流量也應一併設定包含 "question:" 和 "context:" 的格式，且順序應與資料集範例中的順序相同。如果您排除結構定義，即使資料集的範例包含確切的問題，模型將無法辨識模式。

在資料集中的每個範例中加入提示或前置碼，也有助於改善調整後模型的效能。請注意，如果資料集中包含提示或前置碼，那麼在推論時向已調整的模型發出提示時，也應包含該提示或前置碼。

Gen AI (生成式 AI)

人工智慧 (AI) 藉由使用機器學習與環境互動並執行工作來模擬人類行為，而不需明確指示輸出的內容。

生成式 AI 是人工智慧的分支，可根據自然語言輸入來建立新內容。 生成式 AI 通常內建於軟體應用程式中，並使用經過大量文字資料定型的語言模型，以產生人類般的自然語言回應，甚至是原始影像。 這類應用程式的其中一個熱門範例是 ChatGPT，這是 OpenAI 所建立的聊天機器人，這是一家與 Microsoft 緊密合作的 AI 研究公司。

生成式 AI 是由遠超過人類一輩子閱讀量的文字、影像、聲音所訓練而成，但卻缺乏普通人類的價值觀及基本判斷能力。「他」就像是個博學多聞、過目不忘的孩子，卻缺乏生活常識；偶爾胡說八道，又時常過度坦誠，因而需要隨時照料。因此，無論單純利用 AI 產生內容，或是將 AI 包裝為自家服務的公司，都應該特別小心謹慎。

InstructLab

What are the components of the InstructLab project?

How is InstructLab different from retrieval-augmented generation (RAG)?

RAG is a cost-efficient method for supplementing an LLM with domain-specific knowledge that wasn’t part of its pretraining. RAG makes it possible for a chatbot to accurately answer questions related to a specific field or business without retraining the model. Knowledge documents are stored in a vector database, then retrieved in chunks and sent to the model as part of user queries. This is helpful for anyone who wants to add proprietary data to an LLM without giving up control of their information, or who needs an LLM to access timely information.

This is in contrast to the InstructLab method, which sources end-user contributions to support regular builds of an enhanced version of an LLM. InstructLab helps add knowledge and unlock new skills of an LLM.

It’s possible to "supercharge" a RAG process by using the RAG technique on an InstructLab-tuned model.

Prompt Engineering

Prompt Engineering - 提示工程

生成式 AI 應用程式傳回的回應品質不僅取決於模型本身，也取決於其所提供的提示類型。 「提示工程」一詞描述提示改善的流程。 設計應用程式的開發人員和使用這些應用程式的取用者，都可以考慮使用提示工程來改善生成式 AI 的回應品質。

提示是我們告知應用程式預期執行操作的方式。 工程師可以利用提示來新增程式的指示。 例如，開發人員可以為教師建置生成式 AI 應用程式，以建立與學生閱讀文字相關的複選問題。 在應用程式開發期間，開發人員可以新增其他規則，定義程式應該根據收到的提示執行哪些操作。

為什麼要使用英文 prompt 而不使用中文提問?

  1. 英文的訓練語料庫占比超過93%，中文約0.04%，使用英文提問時，它能返回更準確的解答。
  2. ChatGPT在一次輸入中，最多處理4096 token——超過上限的任何字符都將被忽略而不會顯示訊息。相較之下，英文的token使用量少，使用英文提問時，它能給予更多篇幅的答案(中文消耗的token約是英文兩倍)。詳細的可參考OpenAI token解答，以及使用官方的token計算器
  3. 返回英文答案後，再使用ChatGPT翻譯成中文就行了。例如：Please write in Traditional Chinese language.

Instruct

# Prompt
You are an expert programmer that writes simple, concise code and explanations. Write a python function to generate the nth fibonacci number.

Response:

Here is a Python function that generates the nth Fibonacci number:

def fib(n):
    if n <= 1:
        return n
    else:
        return fib(n-1) + fib(n-2)

This function uses the recursive formula for the Fibonacci sequence, which is:

fib(n) = fib(n-1) + fib(n-2)

Code Review

# Prompt
Where is the bug in this code?

def fib(n):
    if n <= 0:
        return n
    else:
        return fib(n-1) + fib(n-2)

Response:

The bug in this code is that it does not handle the case where `n` is equal to 1.

Unit Tests

# Prompt
write a unit test for this function: $(cat fib.py)

Response:

Here's an example of how you could write a unit test for the `fib` function:

```
import unittest

class TestFib(unittest.TestCase):
    def test_fib(self):
        self.assertEqual(fib(0), 0)
        self.assertEqual(fib(1), 1)
        self.assertEqual(fib(2), 1)
        self.assertEqual(fib(3), 2)
        self.assertEqual(fib(4), 3)
        self.assertEqual(fib(5), 5)
        self.assertEqual(fib(6), 8)
        self.assertEqual(fib(7), 13)
        self.assertEqual(fib(8), 21)
        self.assertEqual(fib(9), 34)
if __name__ == '__main__':
    unittest.main()
```

This test case covers all the cases where the input is an integer between 0 and 9, inclusive.

Code Completion

# Prompt
# A simple python function to remove whitespace from a string:

Response:

def remove_whitespace(s):
    return ''.join(s.split())

Infill: <PRE> {prefix} <SUF>{suffix} <MID>

# Prompt
<PRE> def compute_gcd(x, y): <SUF>return result <MID>

Response:

  if x == y:
        return x

    if x > y:
        x = x - y
    else:
        y = y - x

    result = compute_gcd(x, y)

CURSOR Prompt

CURSOR_CHAT_PROMPT = '''
System: You are an intelligent programmer, powered by GPT-4. You are happy to help answer any questions that the user has (usually they will be about coding).

1. Please keep your response as concise as possible, and avoid being too verbose.

2. When the user is asking for edits to their code, please output a simplified version of the code block that highlights the changes necessary and adds comments to indicate where unchanged code has been skipped. For example:
```file_path
// ... existing code ...
{{ edit_1 }}
// ... existing code ...
{{ edit_2 }}
// ... existing code ...
```
The user can see the entire file, so they prefer to only read the updates to the code. Often this will mean that the start/end of the file will be skipped, but that's okay! Rewrite the entire file only if specifically requested. Always provide a brief explanation of the updates, unless the user specifically requests only the code.

3. Do not lie or make up facts.

4. If a user messages you in a foreign language, please respond in that language.

5. Format your response in markdown.

6. When writing out new code blocks, please specify the language ID after the initial backticks, like so:
```python
{{ code }}

Function Calling

LLM（Large Language Model）的一個新功能是 Function Calling（函數呼叫）。這項功能允許LLM直接呼叫外部函數，並將其結果整合到模型的輸出中。下面是它的工作原理和應用： 
工作原理
 Function Calling 的工作原理是，LLM 在生成輸出時，可以 reconocize 具體的函數名稱和參數，並將其傳遞給外部函數執行。外部函數執行後，將結果返回給LLM，LLM 則將其整合到輸出中。這個過程可以重複多次，實現多個函數的呼叫和整合。

範例
例如，假設有一個LLM需要生成一個天氣報告，LLM 可以呼叫一個外部函數，該函數可以從天氣API中獲取当前的天氣資訊。 LLＭ將函數的結果整合到輸出中，生成一個完整的天氣報告。

應用
Function Calling 的應用非常廣泛，以下是一些例子：
總之，Function Calling 是 LLM 的一個強大功能，可以擴展模型的能力，實現更加 Complex 和多樣化的任務。

LLM Engine

OpenLLM

OpenLLM helps developers run any open-source LLMs, such as Llama 2 and Mistral, as OpenAI-compatible API endpoints, locally and in the cloud, optimized for serving throughput and production deployment.

Install

Recommend using a Python Virtual Environment

pip install openllm
Start a LLM Server
openllm start microsoft/Phi-3-mini-4k-instruct --trust-remote-code

To interact with the server, you can visit the web UI at http://localhost:3000/ or send a request using curl. You can also use OpenLLM’s built-in Python client to interact with the server:

import openllm

client = openllm.HTTPClient('http://localhost:3000')
client.generate('Explain to me the difference between "further" and "farther"')
OpenAI Compatible Endpoints
import openai

client = openai.OpenAI(base_url='http://localhost:3000/v1', api_key='na')  # Here the server is running on 0.0.0.0:3000

completions = client.chat.completions.create(
  prompt='Write me a tag line for an ice cream shop.', model=model, max_tokens=64, stream=stream
)
LangChain
from langchain.llms import OpenLLMAPI

llm = OpenLLMAPI(server_url='http://44.23.123.1:3000')
llm.invoke('What is the difference between a duck and a goose? And why there are so many Goose in Canada?')

# streaming
for it in llm.stream('What is the difference between a duck and a goose? And why there are so many Goose in Canada?'):
  print(it, flush=True, end='')

# async context
await llm.ainvoke('What is the difference between a duck and a goose? And why there are so many Goose in Canada?')

# async streaming
async for it in llm.astream('What is the difference between a duck and a goose? And why there are so many Goose in Canada?'):
  print(it, flush=True, end='')
