            QUESTION

            Use of 1-a weight in categorical focal loss
            Asked 2019-Sep-12 at 13:25

            I am trying to use focal loss in keras/tensorflow with multiple classes which leads to use Categorical focal loss I guess. I have found some implementation here and there or there.

            As far as I get it the parameter a in focal loss is mainly used in the Binary focal loss case where 2 classes exist and the one get a as a weight and the other gets 1-a as weight. In the case of the Categorical focal loss all implementations I found use only weight a in front of each class loss like:

            ...

            I'm as puzzled as you are as to why they multiply the loss by a constant. The code you supplied has alpha as a parameter with the default value set to 0.25, but perhaps when you call the function you're supposed to instead supply a tensor (with the same shape as y_pred/y_true) with the weights to this parameter? That's the only explanation I can think of.

            However, I do think you might be able to simply omit those weights in the code altogether, and instead supply your weights to tf.fit()'s class_weight parameter, and then that'll do the weighting for you. Could you keep me updated on whether that works?
