Circulant singular spectrum analysis
WebMay 22, 2024 · Circulant Singular Spectrum Analysis CiSSA is an algorithm that decomposes the original time series into the sum of a set of oscillatory components at known frequencies. Its main advantage is that users can group the extracted components according to their needs because those components are precisely identified by frequency.
