I have participated in many competitions but to be honest this was a tough one. First I want to thank @JONNY for the starter notebook , I am pretty sure most of us could not have been in the leaderboard if it was not for him, Our unsung hero :).
Honestly, I still don't get it how guys got >0.50 with no duplicates, and even after review , guys have >0.80, okay thats amazing. You guys should post your solutions so that we might learn from you.
Attached is my code solution, this should get you to top 15 and I bet top 10 if you ensemble but it wont get you to 0.80 haha
And btw you guys can try to improve it, In some parts I don't have the most efficient code , for example the first part where I have a list of users , I was lazy to automate that but you can try that, and maybe more features can be added. Anyone with a question can ask as a comment to this discussion and I will try to answer. Happy zinding everyone and I hope 'us' the students are preparing for Umoja Hack.
This is selfless. Thank you for sharing
Combined efforts from myself and my great brother @100i from Ghana.
