How to understand the calculation process of normalized_cls_score？

[ytoon]

In our mehtod, the final class score output is sigmoid(cls_score)*sigmoid(objectness). For the sake of simplicity, we use sigmoid(normalized class score) as the final class score output. These two outputs is equal: sigmoid(normalized class score) = sigmoid(cls_score)*sigmoid(objectness). You can check this equation by yourself.

I did not understand this code, can anyone help me understand this code?

Have you ever make clear what does this equation mean? I can't understand this either. It seems complicate and meaningless...
