Givens Coordinate Descent Methods for Rotation Matrix Learning in Trainable Embedding Indexes

Yunjiang Jiang, Han Zhang, Yiming Qiu +3

Product quantization (PQ) coupled with a space rotation, is widely used in modern approximate nearest neighbor (ANN) search systems to significantly compress the disk storage for e…
