DTWDistance

class DTWDistance(points_distance: typing.Callable[[float, float], float] = CPUDispatcher(<function simple_dist>), trim_series: bool = False)[source]

Bases: etna.clustering.distances.base.Distance

DTW distance handler.

Init DTWDistance.

Parameters

  • points_distance (Callable[[float, float], float]) – function to be used for computation of distance between two series’ points

  • trim_series (bool) – True if it is necessary to trim series, default False.

Notes

Specifying manual points_distance might slow down the clustering algorithm.
