While trying to find approaches for this problem, I encountered a dataset online.
After training the model on this extra dataset, I make the submission; the MAE is 0.0 and F! is 1.0 as in here:
Does the rule allow this? @mohanty
If this is the case that the rule does not allow, could you help to remove my above 2 submissions?
Furthermore, I think we should make clear about this public dataset. So all participants can start with equal data.
