Dr. Patrick Lewis, who coined the term RAG (Retrieval Augmented Generation) and now works at Cohere, discusses the evolution of language models, RAG systems, and challenges in AI evaluation.

MLST is sponsored by Brave:

The Brave Search API covers over 20 billion webpages, built from scratch without Big Tech biases or the recent extortionate price hikes on search API access. Perfect for AI model training and retrieval augmented generation. Try it now - get 2,000 free queries monthly at http://brave.com/api.

Key topics covered:

- Origins and evolution of Retrieval Augmented Generation (RAG)

- Challenges in evaluating RAG systems and language models

- Human-AI collaboration in research and knowledge work

- Word embeddings and the progression to modern language models

- Dense vs sparse retrieval methods in information retrieval

The discussion also explored broader implications and applications:

- Balancing faithfulness and fluency in RAG systems

- User interface design for AI-augmented research tools

- The journey from chemistry to AI research

- Challenges in enterprise search compared to web search

- The importance of data quality in training AI models
