TimeES: Probabilistic and Deterministic Time Series Forecasting via Evolutionary Spectra

Weiwei Ye, Renhe Jiang, Hangchen Liu +2

Real-world time series are inherently non-stationary, with trends, periodic patterns, and uncertainty evolving over time. While the Fourier domain offers a natural lens to model ti…
