Configuration for Product Quantization

Fields

num_subspaces: usize

Number of subspaces (M). Vector is divided into M segments. Typical values: 4, 8, 16, 32

num_centroids: usize

Number of centroids per subspace (K). Typically 256 (fits in u8).

kmeans_iterations: usize

Number of k-means iterations for training

training_sample_size: usize

Sample size for training (if 0, use all vectors)
