Study Notes

Marina Danilevsky is a Senior Research Scientist at IBM Research.
She discussed the challenges of large language models (LLMs) in generating accurate and up-to-date responses.
LLMs can provide incorrect answers due to lack of sources and being outdated.
Danilevsky used an anecdote about giving her kids an incorrect answer about the solar system's planet with the most moons to illustrate this issue.
She introduced Retrieval-Augmented Generation (RAG) as a solution, focusing on the "Generation" part.
RAG enables LLMs to access external sources of information before generating a response to a user query.
RAG improves accuracy and up-to-dateness by allowing LLMs to retrieve and consider the most recent and reliable information from a content store.
RAG also ensures that LLMs give proper credit to their sources and do not hallucinate or leak data.
Danilevsky emphasized the importance of improving both the retrieval system and the LLM to ensure the best possible responses for users.
