Definition of all_stages_loss, how to choose suitable coefficient for separate stage loss?

[zwlshine]

Definition of all_stages_loss is: self.all_stages_loss = 0.4 * self.total_wght_loss + 0.8 * self.stage2_loss + self.stage3_loss, why use 0.4、0.8、1 as the three stage's loss coefficient?

I tried several different weighting parameters, it turns out that there exists no big difference, details can be found in my paper.

@JohnleeHIT
These weighting parameters really have big influence on dice of segmentation.
