WebbA shapelet is a time-series subsequence that allows for TSC based on local, phase-independent similarity in shape. Shapelet-based classification uses the similarity between a shapelet and a series as a discriminatory feature. One benefit of the shapelet approach is that shapelets are comprehensible, and can offer insight into the problem domain. WebbShapelet Transform¶ The Shapelet Transform algorithm extracts shapelets from a data set of time series and returns the distances between the shapelets and the time series. A …
