HIGHLIGHTS
- who: Weishu Chen and colleagues from the Beijing University of Posts and Telecommunications, Beijing, China have published the article: Severe Precipitation Recognition Using Attention-UNet of Multichannel Doppler Radar, in the Journal: (JOURNAL)
- what: In this study, a UNet-based network named Reweighted Regression Encoder-Decoder Net (RRED-Net) is proposed for QPE. The authors design a feature selection method combining information gain and Chi square to avoid the brutal exhaustive selection. In this work, a new loss function named regression focal loss (RF loss) is proposed to solve this kind of data imbalance problem . . .
