Trustworthiness

stats::trustworthiness_score

Compute the trustworthiness score

1 double trustworthiness_score(
2 raft::resources const& handle,
3 raft::device_matrix_view<const float, int64_t, raft::row_major> X,
4 raft::device_matrix_view<const float, int64_t, raft::row_major> X_embedded,
5 int n_neighbors,
6 cuvs::distance::DistanceType metric = cuvs::distance::DistanceType::L2SqrtUnexpanded,
7 int batch_size                      = 512);

Note: The constness of the data in X_embedded is currently casted away and the data is slightly
modified.

Parameters

Name	Direction	Type	Description
`handle`	in	`raft::resources const&`	the raft handle
`X`	in	`raft::device_matrix_view<const float, int64_t, raft::row_major>`	Data in original dimension
`X_embedded`	in	`raft::device_matrix_view<const float, int64_t, raft::row_major>`	Data in target dimension (embedding)
`n_neighbors`	in	`int`	Number of neighbors considered by trustworthiness score
`metric`	in	`cuvs::distance::DistanceType`	Distance metric to use. Euclidean (L2) is used by default Default: `cuvs::distance::DistanceType::L2SqrtUnexpanded`.
`batch_size`	in	`int`	Batch size Default: `512`.

Returns

double

Trustworthiness score
