What metric is used here? Try to figure out cv-sheme. Am I understood correct that we have a regression problem? So, I guess there should something like RMSE or R2?
Copied and pasted from Info > Evaluation:
"The error metric for this competition is the Root Mean Squared Error."
Thanks, not seen
Yes this is a multiple Linear regression problem
For regression problem : MSE, MAES ....
For classification problem : accuracy, recall, ....
