#include <itkDecisionRule.h>

Detailed Description

Base class for decision rules that return a class label based on a set of discriminant scores.

DecisionRule is the base class for decision rules used in classification. Subclasses of DecisionRule include MaximumDecisionRule, MinimumDecisionRule, and MaximumRationDecisionRule, This class has a pure virtual function, Evaluate(), which implements the particular decision rule, given a set of discriminant scores. Concrete subclasses of DecisionRule must implement this method.

◆ Evaluate()

virtual ClassIdentifierType itk::Statistics::DecisionRule::Evaluate ( const MembershipVectorType & discriminantScores ) const

pure virtual

Evaluate the decision rule. The return value of this function is a class label. Functions returns the best label given the discriminant scores using its internal logic.

Implemented in itk::Statistics::MaximumDecisionRule, itk::Statistics::MaximumRatioDecisionRule, and itk::Statistics::MinimumDecisionRule.
