Build a specification for the "ivfpq" KNN query algorithm.

Build a specification of the inverted-file-product-quantization KNN query algorithm, with all required parameters specified explicitly.

Usage

cuda_ml_knn_algo_ivfpq(nlist, nprobe, m, n_bits)

Arguments

nlist

Number of cells to partition dataset into.

nprobe

At query time, the number of cells used for approximate nearest neighbor search.

m

Number of subquantizers.

n_bits

Bits allocated per subquantizer, from 4 to 8. The product of m and n_bits must be divisible by 8.

Value

An object encapsulating all required parameters of the "ivfpq" KNN query algorithm.
