WebSingular Spectrum Analysis (SSA) is a non-parametric procedure based on subspace algorithms for signal extraction [1]. The main task in SSA is to extract the underlying signals of a time series like the trend, cycle, seasonal and irregular components. It has been applied to a wide range of time series WebMay 12, 2024 · In this study, a circulant singular spectrum analysis (CiSSA)-based novel approach for forecasting daily streamflow data is proposed. Obtained features using CiSSA methods are applied to support vector regression (SVR), random forest (RF), and artificial neural network (ANN) models.
