Webshapelet are long and short sequences of ordered values, respectively. Let T2RI Q be I time-series instances of length Q, and let S2RK L be K shapelets of length L. We denote the jth value of the ith time-series instance Ti as Ti;j, and the lth value of the kth shapelet Sk as Sk;l. In total, there are J:=Q L+1 segments of length L for each time ... WebMar 4, 2024 · This is done by sliding a shapelet over each time-series, computing the distances with all its subsequences and finally finding the minimum distance. Using this new feature space as input for traditional classifiers such as SVM or Random Forest has shown to improve classification accuracy compared to the original tree-based approach (Lines et …
