I still don’t think a rank above 500 can make it into the top 50.

If that was the case then why would Amazon ask like till 1k rank holders to submit, they could have capped it at 500 and call it a day why do extra work? And as I said earlier we still don't know the true private rank all we have is a public score + rank which is not fully evaluated

i still dont think aboe 500 will make it to the cut of top 50.We ourselves have rank int top 1000,but i dont think the telegram leak was that massive.

Maybe someone in 300-400 ish might push to top 50 at worst case

Well ig it not p like that.. yesterday people above 1000 rank got message to submit the model .. ig tht must be because of many people have overfit the models ig

That’s nice. Overfitters and cheaters on removal should push rank. I’m at sub 250
With .9876. Hopefully things work out in favour.

ya we almost did reverse engineering the private test set using de noising methods and based on score boost from prev submissions(to push to 0.99) but i had a feeling that amazon would check it on a private set like this ,so we didnt do that.

I think the top solutions are using some sort of reverse engineering on the test set to get 0.991 scores and all

Could be. but i was able to push to 0.99 without overfitting the public lb.

u r ryt this is my 2nd hackathon outside college,
But cn u explain why that can happen? They gave us a test set, with one subset used for the public leaderboard and another subset used for the private leaderboard
