The shocklet transform: a decomposition method for the identification of local, mechanism-driven dynamics in sociotechnical time series

Abstract We introduce a qualitative, shape-based, timescale-independent time-domain transform used to extract local dynamics from sociotechnical time series—termed the Discrete Shocklet Transform (DST)—and an associated similarity search routine, the Shocklet Transform And Ranking (STAR) algorithm,...
