-
class IStoppingCriterion¶
- #include <stopping_criterion.hpp>
Defines an interface for all stopping criteria that allow to decide whether additional rules should be induced or not.
Public Functions
-
inline virtual ~IStoppingCriterion()¶
-
virtual Result test(const IStatistics &statistics, uint32 numRules) = 0¶
Checks whether additional rules should be induced or not.
- Parameters:
statistics – A reference to an object of type
IStatistics
that will serve as the basis for learning the next rulenumRules – The number of rules induced so far
- Returns:
A value of the enum
Result
that specifies whether the induction of rules should be continued (CONTINUE
), whether the current number of rules should be stored as a potential point for stopping while continuing to induce rules (STORE_STOP
), or if the induction of rules should be forced to be stopped (FORCE_STOP
)

class IStoppingCriterionFactory¶
- #include <stopping_criterion.hpp>
Defines an interface for all factories that allow to create instances of the type
IStoppingCriterion
.Subclassed by StoppingCriterionListFactory

inline virtual ~IStoppingCriterionFactory()¶
-
virtual std::unique_ptr<IStoppingCriterion> create(const SinglePartition &partition) const = 0¶
Creates and returns a new object of type
IStoppingCriterion
.- Parameters:
partition – A reference to an object of type
SinglePartition
that provides access to the indices of the training examples that belong to the training set and the holdout set, respectively- Returns:
An unique pointer to an object of type
IStoppingCriterion
that has been created
-
virtual std::unique_ptr<IStoppingCriterion> create(BiPartition &partition) const = 0¶
Creates and returns a new object of type
IStoppingCriterion
.- Parameters:
partition – A reference to an object of type
BiPartition
that provides access to the indices of the training examples that belong to the training set and the holdout set, respectively- Returns:
An unique pointer to an object of type
IStoppingCriterion
that has been created

class IStoppingCriterionConfig¶
- #include <stopping_criterion.hpp>
Defines an interface for all classes that allow to configure a stopping criterion that allows to decide whether additional rules should be induced or not.
