Is there a github for the results cited in this paper? If not then I have one confusion despite the paper being awesomely written. We need more like this. I dislike the lifeless way the new research is communicated. I have to force to read them but not to this so much.

Now coming to the question- Is the input size and output size same that is why box top-left coordinated (bx, by) prediction corresponds to offset(cx) + prediction (sigma(tx)) and similar for y?
