At overview https://www.crowdai.org/challenges/ieee-investment-ranking-challenge you have:
n/(n+i) in DCG coefficient.
Meanwhile looks like you have n/(n-i) in github metric https://www.crowdai.org/challenges/ieee-investment-ranking-challenge
I checked the data inside metric function and I tried to train it with “+” instead - it gave me worse result.
* it has to be minus in overview
* or it has to be plus in github (and why then result trained with plus is evaluated worse on LB?)

@cyga Thanks for the heads up! I assume you were referring to the DCG calculation in the random forest starter kit. The DCG in the overview is the correct formulation. We will update the starter kit to reflect this.
