H2O Multinomial Scorer

Scores multinomial classification predictions.


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.

Input Ports

H2O Frame with actual class column and the predicted probability columns.

Output Ports

The confusion matrix.
The accuracy statistics table.


Confusion Matrix
Displays the confusion matrix in a table view.
