Struct PQConfig 

pub struct PQConfig {
    pub num_subvectors: usize,
    pub num_centroids: usize,
    pub training_iterations: usize,
}

Product Quantizer configuration

Fields

num_subvectors: usize

Number of subvectors (M) Common values: 8, 16, 32 Higher = better accuracy, more memory

num_centroids: usize

Number of centroids per subspace (K) Common values: 256 (1 byte), 65536 (2 bytes) Must be power of 2 for optimal packing

training_iterations: usize

Number of training iterations for k-means
