Описание к видео Timeseries Data Classification in Python with Symbolic Aggregate Approx. & Vector Space Modeling

This is a course on Timeseries Data Classification. Timeseries data analysis using classification methods like bag of words approach called Symbolic Aggregate Approximation is discussed with Vector Space Modeling.
What is timeseries data, timeseries data analysis types and characteristics of timeseries data are discussed. Classifying labels on timeseries data using SAX-VSM method is described and the algo implementation is shown in a jupyter notebook demo in the end.
