GBM Building Does Not Stop when Error Reaches 0 #11211

Open exalate-issue-sync[bot] opened 1 year ago

exalate-issue-sync[bot] commented 1 year ago

When trying a trivial example where the predictor is equal to the response, the first GBM model in the grid search will not stop training even after logloss has reached 0.

A reproducible example is attached.

{code}

Create Data - predictor is equal to response

iris_h2o <- as.h2o(iris) iris_h2o$C1 <- iris_h2o$Species iris_h2o <- iris_h2o[c("C1", "Species")]

Run AutoML

aml <- h2o.automl(response_column = "Species", training_frame = iris_h2o) {code}
