WebSep 15, 2015 · 5. It just happened that few days ago I read Marco Cuturi's paper on "Fast Global Alignment Kernels" [1]. The idea is to cast the well-known DTW distances as similarities eligible for use in kernel machines, e.g. SVM. You cannot directly transform DTW distance into similarity and hope it will work (e.g. negative exponential of distance) - you ... WebTime series clustering with a wide variety of strategies and a series of optimizations specific to the Dynamic Time Warping (DTW) distance and its corresponding lower bounds (LBs). There are implementations of both traditional clustering algorithms, and more recent procedures such as k-Shape and TADPole clustering.
