WebFeb 4, 2024 · Window size selection (WSS) algorithms can be divided into two major categories: (a) whole-series-based and (b) subsequence-based. Whole-series-based methods analyse global properties of a signal in order to detect dominant period sizes. They can further be divided into frequency-based and time-based approaches.
