Me too. The first time to deal with data inconsistency in kaggle for me. This is a valuable lesson.

Same here. I lucked out and one of my other models landed a bronze medal, but this will be a nice lesson for future competitions down the road.

Many of my submits with high resolution were also overfitted to public LB. But I am so lucky because one of four was submitted with original shape. We should use the same shape as training shape…

The first time I had faced a shakeup, I was so sad and didn't come back to comp for many months. I hope you take the learning and win 🏅 s in the future :)

It was only very late in the competition that I learned there's only 5 video. 3 for training, 1 public lb, 1 private lb. That was a wake up call for me, telling me I shouldn't pick based on public lb alone. I'd be in the shake down hell were it not for that one comment I read less than 36 hours away from deadline.

I think many people experienced something similar for this competition. Have submissions that would have done well on the private lb but didn't choose to submit it.
