Now that the leaderboard has been sealed , how about the top guys they share how they approached the problem. We would really love to learn from them. Congrats @Yisakberhanu I was rooting for you. Looking forward for the next birthday challenge😁

My guess is that they they submitted multiple times (inadvertantly) for a subset of the positive-labelled users. Zindi never fixed the calculation bug, they purely looked at intentional manipulation rather than accidental.

They did, this morning

No they say they fixed it but they didn't actually fix it.

And to show this isn't just me being jealous: if they actually fix the issue and in the SMALL chance I win a prize I will forgo it and pass it on to the next rank.

I think they fixed it , yisakberhanu had the highest score with no duplicate values and I can see he is the top guy, I bet even ridadokar despite having 0.83 he had a higher score than us with no duplicate values so that's what i think

they have calculated the accuracy instead of the f1 score, what solution is this!?

Thank you @Koleshir , i will post my winning apperochs
