PESD-TSF: A Period-Aware and Explicit Structured Decomposition Framework for Long-Term Time Series Forecasting

In three linesPESD-TSF is a physics-inspired structured decomposition framework for long-term time series forecasting. It introduces a Multiplicative Periodic Gating mechanism, a multi-scale encoder with detrended attention, and Cross-Scale Collaborative Attention (CSCA) to preserve periodic structures and inter-variable dependencies across deep layers.
