Fields

threshold: f32

The classification threshold.

true_positives: u64

The total number of examples whose label is equal to the positive class that the model predicted as belonging to the positive class.

false_positives: u64

The total number of examples whose label is equal to the negative class that the model predicted as belonging to the positive class.

true_negatives: u64

The total number of examples whose label is equal to the negative class that the model predicted as belonging to the negative class.

false_negatives: u64

The total number of examples whose label is equal to the positive class that the model predicted as belonging to the negative class.

accuracy: f32

The fraction of examples that were correctly classified.

precision: Option<f32>

The precision is the fraction of examples the model predicted as belonging to the positive class whose label is actually the positive class. true_positives / (true_positives + false_positives). See Precision and Recall.

recall: Option<f32>

The recall is the fraction of examples whose label is equal to the positive class that the model predicted as belonging to the positive class. recall = true_positives / (true_positives + false_negatives).

f1_score: Option<f32>

The f1 score is the harmonic mean of the precision and the recall. See F1 Score.

true_positive_rate: f32

The true positive rate is the fraction of examples whose label is equal to the positive class that the model predicted as belonging to the positive class. Also known as the recall. See Sensitivity and Specificity.

false_positive_rate: f32

The false positive rate is the fraction of examples whose label is equal to the negative class that the model falsely predicted as belonging to the positive class. false_positives / (false_positives + true_negatives). See False Positive Rate
