How come the RMSE for the top 1 can be 0? Does it mean there is a data leak? Please stop such behavior, otherwise the data challenge is ruined.
I just want to remind the participants, that this is a learning challenge and RMSE score is not the sole metric that we use to pick the winners. We would like to use the approach to predicting the emissions in conjunction with the prediction score to pick the winner.
If the result is not from machine learning models or mathematical models, the team will be disqualified in the source code reviewing phase, correct?
Yes, that is correct.
