Sebastian Riedel
Google DeepMindResearch Scientist
Riedel co-authored the 2020 paper on retrieval-augmented generation (RAG), a method that lets language models look up relevant documents before writing an answer.[1] His earlier work tested which facts models could recall from training alone[2]; he later helped develop a method for finding evidence spread across multiple documents[3].
