What is the metric used in the gridsearch result ?

I'm doing a hyper parameter optimization for XGBoost and Dataiku is displaying grid scores but there is no information on what it is.

Hi,

The metric used for gridsearch is configurable in the settings , in "Learning Task", "Optimize model for".

By default, the model is optimized for AUC on classification, R2 score on regression

Hi,

On the top left model comparison screen (with the cup symnol for the best model) the RMSE is different from the RSME end result from the grid search of that same mode. ea: 0.196 in the topleft screen versus 0.243 in the actual grid plot.

How should this be interpreted?
