The list of trainers for performing binary classification.

Methods

ChangeModelThreshold<TModel>(BinaryPredictionTransformer<TModel>, Single)

Method to modify the threshold to existing model and return modified model.

CrossValidate(IDataView, IEstimator<ITransformer>, Int32, String, String, Nullable<Int32>)

Run cross-validation over numberOfFolds folds of data, by fitting estimator, and respecting samplingKeyColumnName if provided. Then evaluate each sub-model against labelColumnName and return a CalibratedBinaryClassificationMetrics object, which includes probability-based metrics, for each sub-model. Each sub-model is evaluated on the cross-validation fold that it did not see during training.

CrossValidateNonCalibrated(IDataView, IEstimator<ITransformer>, Int32, String, String, Nullable<Int32>)

Run cross-validation over numberOfFolds folds of data, by fitting estimator, and respecting samplingKeyColumnName if provided. Then evaluate each sub-model against labelColumnName and return a BinaryClassificationMetrics object, which do not include probability-based metrics, for each sub-model. Each sub-model is evaluated on the cross-validation fold that it did not see during training.

Evaluate(IDataView, String, String, String, String)

Evaluates scored binary classification data.

EvaluateNonCalibrated(IDataView, String, String, String)

Evaluates scored binary classification data, without probability-based metrics.

Extension Methods

PermutationFeatureImportance<TModel>(BinaryClassificationCatalog, ISingleFeaturePredictionTransformer<TModel>, IDataView, String, Boolean, Nullable<Int32>, Int32)

Permutation Feature Importance (PFI) for Binary Classification.

PermutationFeatureImportanceNonCalibrated(BinaryClassificationCatalog, ITransformer, IDataView, String, Boolean, Nullable<Int32>, Int32)

Permutation Feature Importance (PFI) for Binary Classification.
