Traditionally most hackathons have a solutions sharing thread, but couldn’t find one for Knocktober. So, here goes:
Congrats to the winners and thanks for your wishes! Really really happy on getting my hat-trick on AV
This was a well-crafted dataset, with plenty ideas on features and EDA. Unfortunately, I was busy at the World Championships on Friday-Saturday, and had my returning flight back to India on Sunday, so couldn’t participate in the channel discussions and other sharing of posts and ideas.
I decided to team up for the first time since I only had a few hours on Saturday. I managed to build a single XGB with 13 features (6 raw + 7 engineered) that scored 0.8375 on the public LB, which ranked 1st and handed over the rest to SRK
Here’s my full code: https://github.com/rohanrao91/AnalyticsVidhya_Knocktober
Our final submission was a weighted average of SRK’s best model and my best model.
I’ll write a detailed post about my approach in this competition and also a general post on my hat-trick sometime later this week.
