Hi,
I have implemented your code and it worked properly but have the following concerns
My sudo code works like this
cls_targets = [batch_size, anchor_boxes, classes] # classes is 21 (voc_la…

It is a great work for yolo training, I am wondering whether it has the plan for focal loss, or anyone wants to develop together?
here is the paper [Focal Loss for Dense Object Detection](https://a…

Hi @unsky ,
The performance in your experiment is amazing. By the way, did you only replace the SoftmaxWithLoss with the focal loss layer in RPN layer or in both RPN and Fast RCNN?

To use the quality focal loss did you passed to it the quality score like [0.1 0.6 0.2 0.4] or you passed the onehot from the target like [0 1 0 0] ?

根据focalloss的原理 应该写成如下形式
focal_loss = tf.abs(target - alpha) * tf.pow(tf.abs(target - actual), gamma)
# 正样本时为 (1-alpha) * tf.pow(actual, gamma)
# 负样本时为 (alpha) * tf.pow((1-actual), gamma)
假如按照你的写法

Hello All, how should I use the focal loss inside the config file? It pops up this strange message for me...
