namespace clue¶

Functions¶

template<std::size_t Ndim, std::floating_point TData = float>
auto silhouette(const clue::PointsHost<Ndim, TData> &points, std::size_t point)¶

Compute the silhouette score for a specific point in the dataset.

Note

This function currently only works for points with non-periodic coordinates.

Template Parameters:¶

std::size_t Ndim¶

The number of dimensions of the points

std::floating_point TData = float¶

The data type for the point coordinates and weights, which must be a floating-point type. By default, it is set to float.

Parameters:¶

const clue::PointsHost<Ndim, TData> &points¶

The dataset containing the points

std::size_t point¶

The index of the point for which to compute the silhouette score

Returns:¶

The silhouette score of the specified point

template<std::size_t Ndim, std::floating_point TData = float>
auto silhouette(const clue::PointsHost<Ndim, TData> &points)¶

Compute the average silhouette score for the entire dataset.

Note

This function currently only works for points with non-periodic coordinates.

Template Parameters:¶

std::size_t Ndim¶

The number of dimensions of the points

std::floating_point TData = float¶

The data type for the point coordinates and weights, which must be a floating-point type. By default, it is set to float.

Parameters:¶

const clue::PointsHost<Ndim, TData> &points¶

The dataset containing the points

Returns:¶

The average silhouette score of the dataset
