IVF-GPU-accelerated kNN graph (deprecated)

The three GPU kNN searches went behind one wrapper, see rs_gpu_knn(). Note that Euclidean distances now come back as true L2 rather than squared.

Usage

rs_ivf_gpu_knn(embd, ivf_params, seed, verbose)

Arguments

embd

Numeric matrix of embeddings, cells x features.

ivf_params

Named list, see params_nn_gpu().

seed

Integer. Random seed for reproducibility.

verbose

Integer. 0L quiet, 1L normal, 2L detailed.

Value

A named list with indices, dist and dist_metric.
