DeltaPQ: Lossless Product Quantization Code Compression for High Dimensional Similarity Search
Summary: Compresses high-dimensional vectors by first quantizing into codes and then applying a tree-based delta encoding (DeltaPQ) to those codes. A linear-time algorithm selects the optimal tree, yielding up to 5× compression and enabling approximate nearest neighbor search directly on the compressed data across inner product, cosine, Euclidean, and Lp norms.
