Equalized Focal Loss for Dense Long-Tailed Object Detection

1 code implementation CVPR 2022 Bo Li, Yongqiang Yao, Jingru Tan, Gang Zhang, Fengwei Yu, Jianwei Lu, Ye Luo

The conventional focal loss balances the training process with the same modulating factor for all categories, thus failing to handle the long-tailed problem.

Cross-Modal Self-Attention Distillation for Prostate Cancer Segmentation

no code implementations8 Nov 2020 Guokai Zhang, Xiaoang Shen, Ye Luo, Jihao Luo, Zeju Wang, Weigang Wang, Binghui Zhao, Jianwei Lu

In this paper, we develop a cross-modal self-attention distillation network by fully exploiting the encoded information of the intermediate layers from different modalities, and the extracted attention maps of different modalities enable the model to transfer the significant spatial information with more details.
