Namespace containing components for binary classification calibration.
Classes
| CalibratedModelParametersBase |
Base class for calibrated model parameters. |
| CalibratedModelParametersBase<TSubModel,TCalibrator> |
Class for allowing a post-processing step, defined by Calibrator, to SubModel's output. |
| CalibratorEstimatorBase<TICalibrator> |
Base class for calibrator estimators. |
| CalibratorTransformer<TICalibrator> |
An instance of this class is the result of calling Fit(IDataView). If you pass a scored data, to the CalibratorTransformer<TICalibrator> Transform method, it will add the Probability column to the dataset. The Probability column is the value of the Score normalized to be a valid probability. The CalibratorTransformer<TICalibrator> is an instance of ISingleFeaturePredictionTransformer<TModel> where score can be viewed as a feature while probability is treated as the label. |
| FixedPlattCalibratorEstimator |
Obtains the probability values by applying the sigmoid: f(x) = 1 / (1 + exp(-slope * x + offset). Note that unlike, say, PlattCalibratorEstimator, the fit function here is trivial and just "fits" a calibrator with the provided parameters. |
| IsotonicCalibrator |
The isotonic calibrator. |
| IsotonicCalibratorEstimator |
The isotonic calbrated estimator. |
| IsotonicCalibratorTransformer |
The ITransformer implementation obtained by training a IsotonicCalibratorEstimator |
| NaiveCalibrator |
The naive binning-based calibrator. |
| NaiveCalibratorEstimator |
The naive binning-based calibrator estimator. |
| NaiveCalibratorTransformer |
The ITransformer implementation obtained by training a NaiveCalibratorEstimator |
| PlattCalibrator |
The Platt calibrator calculates the probability following: P(x) = 1 / (1 + exp(Slope * x + Offset) |
| PlattCalibratorEstimator |
The Platt calibrator estimator. |
| PlattCalibratorTransformer |
The ITransformer implementation obtained by training a FixedPlattCalibratorEstimator or a PlattCalibratorEstimator. |
Interfaces
| ICalibrator |
An interface for probability calibrators. |
Remarks
These components calculate probabilities from scores, for binary classifiers.
