Shapelet Implementations Most shapelet implementations were done in C++ or … NettetFirst, searching or learning shapelets in the raw time series space incurs a huge computation cost. For example, it may cost several hours to deal with only hundreds of …
NettetShapelet represents the time series local shape features; thus, the linear combination of Shapelets can represent time series partially or totally. This behaviour is similar to the … NettetThis estimator consists of two steps: computing the distances between the shapelets and the time series, then computing a logistic regression using these distances as …
