Reflection-Tuning: Data Recycling Improves LLM Instruction-Tuning

The Podcast is generated with Google's Illuminate, the tool trained on AI & science-related Arxiv papers.

Reflection-Tuning Paper from 2023: An Approach for Data Recycling, where LLMs can fix their own mistakes by reflecting on the previous mistakes.

- Improves the quality of instruction-tuning data.

- Models trained on recycled data show significant improvements in performance across multiple benchmarks.

🧠 The method operates on two main phases:

1. Instruction Reflection

2. Response Reflection

Both phases use an oracle model (e.g. GPT4) to analyze and improve the existing data.

🛠️ The process step-by-step:

1️⃣ Data Preparation

- The process starts with an existing instruction-tuning dataset (e.g., Alpaca or WizardLM).

- Each data point consists of an instruction-response pair.

2️⃣ Instruction Reflection

- For each instruction-response pair:

a. The pair is fed into the oracle model (e.g. GPT4) along with specific criteria for reflection.

b. Criteria include:

- Complexity of the Topic

- Level of Detail Required

- Knowledge Required

- Ambiguity of the Instruction

- Logical Reasoning or Problem-Solving Involved

c. The oracle model analyzes the instruction based on these criteria.

d. It then generates a new, improved instruction.

3️⃣ Response Reflection

- For each newly generated instruction:

a. The instruction is fed into the oracle model along with new criteria.

b. Criteria for response reflection include:

- Helpfulness

- Relevance

- Accuracy

- Level of Details

c. The oracle model generates an improved response based on these criteria.

4️⃣ Data Recycling

- The new instruction-response pair replaces the original in the dataset.

- This process is repeated for all pairs in the dataset.

5️⃣ Model Training

- The recycled dataset is used to fine-tune a base LLM (e.g., Llama3.1-8B).

📊 Evaluation

The recycled dataset is evaluated using various metrics:

- Instruction and response lengths

- Perplexity scores

- Coherence between instructions and responses

- IFD scores
