gtda.point_clouds: Point clouds

The module gtda.homology implements transformers to process point clouds and modify metric spaces.

point_clouds.ConsistentRescaling([metric, …])

Rescaling of distances between pairs of points by the geometric mean of the distances to the respective \(k\)-th nearest neighbours.

point_clouds.ConsecutiveRescaling([metric, …])

Rescaling of distances between consecutive pairs of points by a fixed factor.
