New McWC model enhances long-term time series forecasting with inter-channel correlation modeling

Researchers have introduced McWC, a novel model designed for long-term time series forecasting that addresses limitations in existing methods. McWC separately models cyclicity, trend, and crucially, inter-channel correlations, which are often overlooked. The model employs a multi-layer cyclicity construction module, a multi-layer perceptron for inter-channel correlations, and a multi-level wavelet decomposition module for frequency information. Experiments on six real-world datasets show that McWC achieves state-of-the-art performance with improved computational efficiency and historical information extraction capabilities. AI

    Multiple cyclicity and Wavelet Decomposition with Channel Correlation for Long-term Time Series Forecasting

    Cyclicity and trend are important components of time series data and many studies based on cyclicity and trend have achieved good results in long-term time series forecasting. However, we believe that current work neglects the influence of real-world inter-channel correlations in…
