Mutual Information Based Reweighting for Precipitation Nowcasting

Yuan Cao, Danchen Zhang, Xin Zheng, Hongming Shan, Junping Zhang

ICASSP 2023accepted

Precipitation nowcasting uses previous rainfall observations to forecast future rainfall intensities in a local area. In rainfall data, the rain-less samples usually well exceed the heavy rainfall samples, and it causes the data imbalance problem in precipitation nowcasting tasks. In this paper, we…

Hybrid Weighting Loss for Precipitation Nowcasting from Radar Images

Yuan Cao, Lei Chen, Danchen Zhang, Leiming Ma, Hongming Shan

ICASSP 2022accepted

Precipitation nowcasting is gaining increasing attention in the signal processing community. Existing deep learning-based studies focus on designing an effective model architecture, neglecting the influence of the severe imbalanced distribution of rainfall data that can compromise the predictive acc…
