3rd Place — Kaggle Playground Season 6, Episode 3
An Ensemble of 100 OOFs
I've been doing Kaggle since last year for fun, starting with the Playground series, which is an easier, tabular competition. It also awards some swag!
After missing out on winning some swag by one place two months ago, I decided to take a month off. However, I couldn't stay away for too long and last month after a lot of work I managed to place 3rd!
This was the Playground Series Season 6, Episode 3 — Customer Churn Prediction.Unlike previous months where I leaned on a single strong model, this time the key ingredient was ensembling.
Every day I jotted down new ways of solving the problem, which was a lot of fun!
I ended up with a pool of 100 out-of-fold (OOF) prediction files that I stacked with a simple
LinearRegression.
