A decomposition-ensemble model with regrouping method and attention-based gated recurrent unit network for energy price prediction

The empirical results measured by various performance metrics verify that the predictive accuracy is evidently improved by ICEEMDAN-R-AttGRU model in most cases compared with single models, ICEEM DAN-based and ICEEMdAN- R-based hybrid models.
