1
Beyond Naive Chunking: Implementing a Parent-Document Retriever
Analyze the failure modes of naive chunking and implement a Parent-Document Retriever in LangChain for improved contextual accuracy.
Multi-Vector Retriever: Summaries for Indexing
Implement a Multi-Vector Retriever in LangChain, using LLM-generated summaries as an alternative representation for indexing.
Hybrid Search with LangChain: Sparse and Dense Retrieval
Construct a hybrid search pipeline in LangChain that combines sparse (e.g., BM25) and dense retrievers to leverage both keyword and semantic matching.
