computeClassificationMetrics
@SerialName(value = "compute_classification_metrics")
If set, we calculate classification-specific metrics such as accuracy and F-1 score using the validation set at the end of every epoch. These metrics can be viewed in the results file.
In order to compute classification metrics, you must provide a validation_file. Additionally, you must specify classificationNClasses for multiclass classification or classificationPositiveClass for binary classification.
