I think another very interesting point brought up was when that even such a well-ranked model on Kaggle did a poor job when applied to an different dataset and had to be retained, which is a nice example of over-fitting.
Excellent article and nice details, thanks!
This second challenge actually featured a different dataset with different hydrophones used etc. But even without retraining (which was rather trivial to do at that point; the hard work of finding the right hyper parameters had already been done), I would have still scored well above 90%. And I think Nick Kridler reported the same.
So overfitting yes, but not too much considering there was a different sensor.
I guess it is technically overfitting, but overfitting sounds wrong when you didn't have access to the extra data in the first place (or even realize you were being given pre-cleaned-up data).
Solution: the first de-noising done with actual noise?
The work is great though. More of this and less bitcoin, godaddy announcements, and SV gossip politics on the front page, please.
