LuckyDtwDist

class LuckyDtwDist(window=None)[source]

Lucky dynamic time warping distance.

Implements lucky dynamic time warping distance [1]_. Uses Euclidean distance for multivariate data.

Based on code by Krisztian A Buza’s research group.

Parameters:

window: int, optional (default=None): Maximum distance between indices of aligned series, aka warping window. If None, defaults to max(len(ts1), len(ts2)), i.e., no warping window.

Attributes:

is_fitted: Whether fit has been called.
