PETformer: Long-term Time Series Forecasting via Placeholder-enhanced Transformer

no code implementations9 Aug 2023 Shengsheng Lin, Weiwei Lin, Wentai Wu, SongBo Wang, Yongxiang Wang

Recently, the superiority of Transformer for long-term time series forecasting (LTSF) tasks has been challenged, particularly since recent work has shown that simple models can outperform numerous Transformer-based approaches.

Mean Field Optimization Problem Regularized by Fisher Information

no code implementations12 Feb 2023 Julien Claisse, Giovanni Conforti, Zhenjie Ren, SongBo Wang

In this paper by adding the Fisher Information as the regularizer, we relate the regularized mean field optimization problem to a so-called mean field Schrodinger dynamics.
