And I've found a great solution: a great technique called Layer-wise Relevance Propagation (LRP), showcased in a paper at ICML `24 by Reduan Achtibat et al allows, allows to precisely score how important each input token was in generating your output! They've made it into a library called LXT. πŸ“Š For each generated output token, LXT gives you attribution scores for each input token. βš™οΈ So I've worked a bit more on aggregating these scores into meaningful spans between successive input and output tokens, and I finally obtained my desired result: RAG with source highlighting! Try the demo here πŸ‘‰ https://huggingface.co/spaces/m-ric/rag_highlights Caveats: - It slows down generation (for now quite a lot, could hopefully be reduced a lot) - For now it supports only specific models: Llama models and Mixtral If there's enough interest in this solution, I can improve it further and spin it off into a specific library for RAG! πŸš€
