"WebDynamic Time Warping holds the following properties: ∀x, x′, DTWq(x, x′) ≥ 0. ∀x, DTWq(x, x) = 0. Suppose x is a time series that is constant except for a motif that occurs at some point in the series, and let us denote by x + k a copy of x in which the motif is temporally shifted by k timestamps, then DTWq(x, x + k) = 0.
