Wan Zhang, Qinjie Lin, Chan Lee, Weijian Li, Han Liu, Kai Zhang
Forecasting multiple time-series with high-dimensional covariates presents a core challenge: unifying common temporal patterns while retaining meaningful series-specific information. We introduce Hopformer (Homogeneity-Pursuit Transformer), a two-stage framework that addresses th…
