Poll Question: Do you like the ability to hide your top scores from other participants?

My Vote: No

Please cast your vote if you have time.


Hello to all participants!

I have a huge concern about the ability to hide your top scores from the leaderboard. You can do it by going to one of your scores in the Results, and pressing the "Post on Leaderboard" link. This ability allows anyone to hide their top score.

I believe that this can cause issues at the end of the competition, because no one will know who how far they actually are from the top submission. Although a submission graph shows the top submission over time, rounded at the nearest 10th across all of the tasks. But I don't think it is quite helpful.

I emailed the organizers about this but haven't heard back.

Hi Nirmal,

Thanks for raising this issue, the organizers will discuss this and get back to you shortly.

My vote is: No too

I find that this makes leaderboards not relevant to the competition. One may check their model performance by submitting their code and checking their scores, and then immediately withdraw it from leaderboard to hide the their performance, which is a signal for other competitors to improve their model. This is almost same as checking their model performance locally with public test data. To prevent this, other participants may run a script that watches leaderboards over time to collect scores appearing for a short period, and that is an effort irrelevant to the aim of the competition in my opinion.

@zhuangyan It looks like someone pulled out their top score, and you got pushed up on the leaderboard...

Agreed: No, we should not be able to hide public submissions.

Thanks for pointing this out. I have contacted Codalab admin to figure out how to force best submission to show up in the leaderboard. They also suggest that it is good idea to always display participants' best submissions. I have changed the competition configuration so that now your best submission(s) will show up in the leaderboard and you cannot take it down.

Let me know if you have further questions or concerns on this, thanks!!
