Derivative dynamic time warping
WebSep 29, 2024 · Dynamic time warping (DTW) has been widely used as a distance measure for time series classification because its matching is elastic and robust in most cases. However, DTW may lead to over compression that could align too many consecutive points from one time series to only one point on another. WebSep 10, 2015 · This pitfall motivates research to propose many variants to mitigate this situation, such as, weighted DTW [15], Derivative Dynamic Time Warping (DDTW) [16] and Shape Contexts DTW [14]. However ...
