Stop Losing Context! How Late Chunking Can Enhance Your Retrieval Systems


Summary

The video discusses a context enhancement technique called late chunking for improving RAG systems. It focuses on parameters like max tokens and embedding dimension to enhance the contextual information within tokens. By utilizing late chunking, the approach retains richer contextual information in embeddings compared to naive chunking, especially beneficial for processing large documents. The technique offers insights into better context models by decomposing embeddings and retaining long context information for a more effective retrieval process. It also addresses the validation requirements and benchmarks necessary for implementing late chunking in embedding models.
