TwinS: Revisiting Non-Stationarity in Multivariate Time Series Forecasting

no code implementations6 Jun 2024 Jiaxi Hu, Qingsong Wen, Sijie Ruan, Li Liu, Yuxuan Liang

In this paper, we begin by validating this theory through wavelet analysis and propose the Transformer-based TwinS model, which consists of three modules to address the non-stationary periodic distributions: Wavelet Convolution, Period-Aware Attention, and Channel-Temporal Mixed MLP.
