Episode notes
Contextual Meaning Transforms NLP
- Traditional NLP represented text by word frequency and co-occurrence, grounded in the distributional hypothesis.
- Attention mechanisms enable contextual meaning, distinguishing identical words based on sentence context, revolutionizing semantic search.
Tokens as Knowledge Building Blocks
- Tokens serve as fundamental building blocks encoding abstract information, combined to produce meaningful language understanding.
- Large language models act as probabilistic indexes over vast training data, generating responses based on token probabilities.
Master Prompt Engineering for RAG
- Build RAG systems by skillfully assembling correct context to reduce hallucinations in LLM responses.
- Understand how models train and follow instructions to optimize context for new tasks and improve retrieval accuracy.
