Overfitting the Leaderboard in Ernst & Young Data Science Competition 2019

And subsequently losing 8000 USD + a ticket to New York.

A bittersweet journey at the latest Ernst & Young NextWave Data Science Competition 2019.

The image above depicts the dramatic free fall of our rank in the global leaderboard. A lot was at stake here. We have sacrificed 40 days pursuing 8000 USD and a ticket to New York — the 1st place prize for the global leaderboard. And to make things even more so anticlimactic, we had dominated the public leaderboard ever since the competition began. Since two weeks before the deadline, our position was set in stone at the 1st place on the leaderboard until the bitter truth, that is the private leaderboard.

Fortunately for us, while we were down to 9th place in the global leaderboard, we were still 1st place on Indonesia local leaderboard. We were rewarded with Rp 25.000.000,- (~1800 USD) and a paid internship offer. Thank you, EY!

So, how did we end up there? Let’s join me on our (Christian Wibisono and I) journey at the latest Ernst & Young NextWave Data Science Competition 2019.
