Unverified倒排乘积量化（IVFPQ）在PQ基础上引入倒排索引结构，通过聚类将向量库分区，将检索复杂度从线性降低至亚线性72% similarUnverifiedVLCQ represents quantized values through variable length coding, so that regions with dense value distributions can use finer codes and sparse regions can use shorter codes.70% similarUnverifiedVector quantization (VQ) maps a group of weights as a whole to the nearest codeword in a pre-learned codebook, storing only the codeword index.67% similarUnverifiedNeither PWLQ nor DFQ breaks out of the premise of fixed code length, whereas VLCQ changes the encoding mechanism itself.64% similarUnverifiedDedicated vector databases have built-in production-oriented features, including distributed sharding and horizontal scaling, quantization compression (PQ, SQ), joint execution of metadata filtering and vector retrieval, multi-tenant isolation, batch writes and consistency control.64% similar
