class IPrediction : public IIndexVector, public IStatisticsUpdate
#include <prediction.hpp>

Defines an interface for all classes that store the scores that are predicted by a rule.

Subclassed by IEvaluatedPrediction

Public Functions

inline virtual ~IPrediction() override
virtual void sort() = 0

Sorts the scores that are stored by this prediction in increasing order by the indices of the outputs they correspond to.

virtual void postProcess(const IPostProcessor &postProcessor) = 0

Post-processes the scores that are stored by this prediction.

Parameters:

postProcessor – A reference to an object of type IPostProcessor that should be used for post-processing

virtual std::unique_ptr<IStatisticsSubset> createStatisticsSubset(const IStatistics &statistics, const EqualWeightVector &weights) const = 0

Creates and returns a new subset of the given statistics that only contains the outputs whose indices are stored in this vector.

Parameters:
