h2o.auc

0th

Percentile

Retrieve the AUC

Retrieves the AUC value from an '>H2OBinomialMetrics. If "train", "valid", and "xval" parameters are FALSE (default), then the training AUC value is returned. If more than one parameter is set to TRUE, then a named vector of AUCs are returned, where the names are "train", "valid" or "xval".

Usage
h2o.auc(object, train = FALSE, valid = FALSE, xval = FALSE)
Arguments
object

An '>H2OBinomialMetrics object.

train

Retrieve the training AUC

valid

Retrieve the validation AUC

xval

Retrieve the cross-validation AUC
