Focal Loss for Dense Object Detection
3. Focal Loss The Focal Loss is designed to address the one-stage ob-ject detection scenario in which there is an extreme im-balancebetween foregroundand backgroundclasses during training (e.g., 1:1000). We introduce the focal loss starting from the cross entropy (CE) loss for binary classification1: CE(p,y)= (−log(p) if y =1 −log(1−p ...
