Why multiply flow ground truth by 0.05?

I was wondering why you multiply ground truth by 0.05. It seems to influence actual learning rate.

It is not equivalent to modifying the learning rate. The reason we did it is to have image and flow values normalized to a range of approximately -0.5 to 0.5. It seems that it is not absolutely necessary though.

Thanks for your reponse. I got your point.
