Mechanism: TURBOQUANT benchmarks PolarQuant and QJL algorithms for compressing high-dimensional biomedical embeddings. Readout: Readout: 4-bit compression achieves 8x space savings with 0.814 Recall@10 and 0.990 cosine similarity, while higher compression rates reduce recall.
Biomedical RAG systems need compressed embedding indices. TURBOQUANT benchmarks PolarQuant (random rotation + scalar quantization) and QJL (1-bit Johnson-Lindenstrauss projection) on synthetic 256-dim embeddings. Results: 4-bit = Recall@10 0.814, cosine 0.990, 8x compression; 3-bit = 0.628, 10.6x; 2-bit = 0.364, 15.9x. Limitation: synthetic data, random rotation not corpus-optimized, brute-force search.
