Configuration for Optimized Product Quantization.

Fields

num_subspaces: usize

Number of subspaces to split the (rotated) vector into.

codebook_size: usize

Codebook size per subspace (max 256 for u8 codes).

num_iterations: usize

Number of k-means iterations for codebook training.

num_opq_iterations: usize

Number of outer OPQ iterations (rotation + PQ alternation).

metric: DistanceMetric

Distance metric used for codebook training and search.
