Hi @AlexeyAB , What is the significant difference between 2 types of detection layer?

AlexeyAB commented 4 years ago

[region] for Yolov2 with softmax-classification (multiclass).
[yolo] for Yolov3 with logistic-classification (multilabel - many classes per object), uses many anchors per object, and CIoU-loss.
