do we need to adopt different weight for different loss?
maybe loss for object classification is not MSE but cross-entropy loss? (as far as i know, yolo v3 adopts binary logistic regression for multi-class classification)
Thanks in advance and look forward to seeing your help!
Hi,
I've checked the training code today and found training loss is the sum of objectness loss with multi-class classification loss and bbox regression loss. I have checked the code written by author who claim loss weight as: (maybe I'm wrong since I'm really not familiar with Darknet framework) https://github.com/pjreddie/darknet/blob/d3828827e70b293a3045a1eb80bfb4026095b87b/cfg/yolov2.cfg#L251 , which is used in https://github.com/pjreddie/darknet/blob/d3828827e70b293a3045a1eb80bfb4026095b87b/src/detection_layer.c#L164 My points is:
Thanks in advance and look forward to seeing your help!
