Sorry, I mostly work on (hobbyist) 3d computer vision and not ML. BTW time of implementation also greatly depends on what you've implemented already. Most papers are a small derivation of some preexisting idea, so I've you've already implemented that idea, there isn't that much work to do on top of it - just modify your existing code. But, if you're just starting with some area, getting up to that point will take time.
