H2O Multinomial Scorer

Scores multinomial classification predictions.

Options

Actual column: Column with actual (ground-truth) predictions.
Column Selection: Columns with per class probabilities. Must be as many as domain of target column used for training. Each column name must contain a string that exactly matches its corresponding class (the output columns of the H2O Predictor (Classification) node satisfy this constraint).
Output scores as flow variables: Activate to receive all scores as flow variables
Prefix of flow variables: The scores (i.e. accuracy, error rate, number of correct and wrong classification) can be exported as flow variables with a hard coded name. This option allows you to define a prefix for these variable identifiers so that name conflicts are resolved.
