Retrieval augmented technology (RAG) is a strong approach that makes use of massive language fashions (LLMs) and vector databases to create extra correct responses to consumer queries. RAG permits LLMs to make the most of massive information bases when responding to consumer queries, enhancing the standard of the responses. Nevertheless, RAG additionally has some downsides. One draw back is that RAG makes use of vector similarity when retrieving context to reply to a consumer question. Vector similarity will not be at all times constant and might, for instance, wrestle with distinctive consumer key phrases. Moreover, RAG additionally struggles as a result of the textual content is split into smaller chunks, which prohibits the LLM from using the complete contexts of paperwork when responding to queries. Anthropic’s article on contextual retrieval makes an attempt to unravel each issues by utilizing BM25 indexing and including contexts to chunks.
My motivation for this text is twofold. First, I want to check out the most recent fashions and strategies inside machine studying. Holding updated with the newest developments inside machine studying is important for any ML engineer and knowledge scientist to most…
