What is it about?
LightCTS is a lightweight framework for correlated time series (CTS) forecasting. It offers efficient models by using plain stacking instead of complex alternate stacking, along with lightweight operator modules (L-TCN and GL-Former) that maintain strong feature extraction capabilities. LightCTS also incorporates a compression scheme to speed up computations. Experimental results demonstrate nearly state-of-the-art accuracy with reduced computational and storage requirements.
