Webwarping window (parameter) tuned was a strong TSC baseline for more than a decade [22]. Many measures with di erent properties and alignment strategies were proposed [4,17,26,38,48] but none of them were able to signi cantly outperform DTW. The Ensemble of Elastic Distances (EE) was the rst algorithm that was signi cantly more accurate than NN ...
