Mitigating Hallucinations and Bias

Implement strategies to reduce LLM hallucinations and address potential biases in both retrieved documents and generated responses.

Taming RAG's Wild Side

Welcome! In this lesson, we'll tackle two big challenges in RAG systems: hallucinations and bias. Understanding and mitigating these is key to building trustworthy AI applications.

Hallucinations are when an LLM generates information that isn't factual or supported by its given context. Bias refers to outputs that unfairly favor or disfavor certain groups or ideas.

Why RAG Still Hallucinates

You might think RAG prevents hallucinations by providing facts. While it helps, they can still occur if:

  • Poor Retrieval: The system fails to find truly relevant documents.
  • Insufficient Context: Retrieved information is too sparse or contradictory.
  • LLM Misinterpretation: The LLM misunderstands the provided context.
  • Context Window Limits: The LLM prioritizes its internal knowledge when context is truncated.
