RAFT: Adapting Language Model to Domain Specific RAG

6 snips
Jun 28, 2024
Sai Kolasani, a researcher at UC Berkeley’s RISE Lab and Arize AI Intern, discusses RAFT, a method to adapt language models for domain-specific question-answering. RAFT improves models' reasoning by training them to ignore distractor documents, enhancing performance in specialized domains like PubMed and HotpotQA. The podcast explores RAFT's chain-of-thought-style response, data curation, and optimizing performance in domain-specific tasks.

ANECDOTE

RAFT Analogy: Textbook and Exam

  • Traditional fine-tuning is like a closed-book exam; RAG is like an open-book assessment.
  • RAFT teaches the model how to use the "textbook" effectively during the "study phase."
ADVICE

Effective Context Utilization in RAG

  • Focus on teaching LLMs to use context effectively in retrieval-augmented generation (RAG).
  • This is the core of RAFT's effectiveness.
ADVICE

Robust RAG Systems

  • Include distractor documents in your RAG system for improved robustness.
  • This helps the model learn to discern relevant information.
