Generative Pretrained Hierarchical Transformer for Time Series Forecasting

no code implementations26 Feb 2024 Zhiding Liu, Jiqian Yang, Mingyue Cheng, Yucong Luo, Zhi Li

Secondly, the one-step generation schema is widely followed, which necessitates a customized forecasting head and overlooks the temporal dependencies in the output series, and also leads to increased training costs under different horizon length settings.
