This article details the practical implementation of three foundational retrieval architectures—BM25, dense vector search, and SPLADE—specifically optimized for resource-constrained environments like a 16GB laptop. It provides critical insights into memory management strategies and crash recovery techniques essential for developers building Retrieval-Augmented Generation (RAG) systems without relying on massive cloud infrastructure.
How I Reproduced BM25, Dense Retrieval, and SPLADE on a 16GB MacBook

A practical reproduction of three retrieval baselines, including the crashes, fixes, and score checks that matter for RAG systems. The post How I Reproduced BM25, Dense Retrieval, and SPLADE on a 16GB MacBook appeared first on Towards Data Science.
