I'm trying DTW from mlpy, to check similarity between time series.

Should I normalize the series before processing them with DTW? Or is it somewhat tolerant and I can use the series as they are?

All time series stored in a Pandas Dataframe, each in one column. Size is less than 10k points.

Any easy way to do this z-normalizaiton in Python? – KcFnMi – 2017-01-03T10:00:48.527

And, by the way, nice presentation! – KcFnMi – 2017-01-03T10:17:11.627

@eamonn What if the data is multimodal? – Alex – 2020-08-22T22:35:08.000
