ValidationResult Object (IValidationResult Interface)

ValidationResult object (IValidationResult interface) in the ABBYY FineReader Engine API — detailed classification-model performance metrics: accuracy, precision, recall, F-measure, and the confusion matrix.

This object contains the detailed result of checking the model’s performance.

Properties

Name	Type	Description
Accuracy	double, read-only	Returns the average accuracy of all the models on all training iterations.
ConfusionMatrix	ConfusionMatrix, read-only	Returns the confusion matrix for the classification model.
FMeasure	double, read-only	Returns the F-measure, or F1 score, of the classification model.
Precision	double, read-only	Returns the precision (positive predictive value) of the classification model.
Recall	double, read-only	Returns the recall, or sensitivity, of the classification model.
StandardDeviation	double, read-only	Returns the standard deviation of the model accuracy calculated on each training iteration.
