Corrective RAG (CRAG)

Why it matters

CRAG shapes robust RAG. Understanding shapes design.

The architecture

Retrieve.

Evaluator scores docs.

Correct: web search + rewrite + strip irrelevant.

Generate with clean context.

How it works end to end

Yan et al. 2024.

Evaluator: small classifier.

Correction: web + rewrite.

Better than blind trust in retrieval.
