Multivariate time series classification with parametric derivative dynamic time warping

作者：

Highlights：

• We improve DTW distance measure in multivariate time series classification.

• We use derivatives to improve DTW in multivariate time series classification.

• We test effectiveness on 18 real time series.

• We present a detailed comparison of proposed methods.
