Class AbstractSupervisedPerformanceEvaluator<InputType,TargetType,EstimateType,ResultType>

java.lang.Object

gov.sandia.cognition.util.AbstractCloneableSerializable

gov.sandia.cognition.learning.performance.AbstractSupervisedPerformanceEvaluator<InputType,TargetType,EstimateType,ResultType>

Type Parameters:

InputType - The input type to evaluate.

TargetType - The type of the ground-truth targets (the labels).

EstimateType - The type of estimate to evaluate.

ResultType - The output type of the performance evalautor.

All Implemented Interfaces:

PerformanceEvaluator<Evaluator<? super InputType,? extends EstimateType>,java.util.Collection<? extends InputOutputPair<? extends InputType,TargetType>>,ResultType>, SupervisedPerformanceEvaluator<InputType,TargetType,EstimateType,ResultType>, CloneableSerializable, Summarizer<TargetEstimatePair<? extends TargetType,? extends EstimateType>,ResultType>, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

AbstractSupervisedCostFunction, ConfusionMatrixPerformanceEvaluator, DefaultBinaryConfusionMatrix.PerformanceEvaluator, MeanAbsoluteErrorEvaluator, MeanSquaredErrorEvaluator, RootMeanSquaredErrorEvaluator

public abstract class AbstractSupervisedPerformanceEvaluator<InputType,TargetType,EstimateType,ResultType>
extends AbstractCloneableSerializable
implements SupervisedPerformanceEvaluator<InputType,TargetType,EstimateType,ResultType>, Summarizer<TargetEstimatePair<? extends TargetType,? extends EstimateType>,ResultType>

The AbstractSupervisedPerformanceEvaluator class contains an abstract implementation of the SupervisedPerformanceEvaluator class. It does the conversion of a dataset of input-target pairs to a set of target-estimate pairs given the estimate returned by the evaluator whose performance is being assessed.
