cuda_ml_knn_algo_ivfpq {cuda.ml}

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

Description

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,
  use_precomputed_tables = FALSE
)

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.

use_precomputed_tables

Whether to use precomputed tables.

Value

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