fastdtw

-------

Python implementation of `FastDTW

`_ [1]_, which is an approximate Dynamic Time Warping (DTW) algorithm that provides optimal or near-optimal alignments with an O(N) time and memory complexity.

Install

-------

::

  pip install fastdtw

Example

-------

::

  

  import numpy as np

  from scipy.spatial.distance import euclidean

  from fastdtw import fastdtw

  x = np.array([[1,1], [2,2], [3,3], [4,4], [5,5]])

  y = np.array([[2,2], [3,3], [4,4]])

  distance, path = fastdtw(x, y, dist=euclidean)

  print(distance)
