Typedefs

typedef std::variant<float32, int32> Threshold

A union of types that may be used for the threshold used by a condition of a rule.

Enums

enum Comparator

An enum that specifies all possible types of operators used by a condition of a rule.

Values:

enumerator NUMERICAL_LEQ

enumerator NUMERICAL_GR

enumerator ORDINAL_LEQ

enumerator ORDINAL_GR

enumerator NOMINAL_EQ

enumerator NOMINAL_NEQ

struct Condition : public Interval

#include <condition.hpp>

Stores the properties of a condition of a rule. It consists of the index of the feature, the condition corresponds to, the type of the operator that is used by the condition, as well as a threshold. In addition, it stores the range [start, end) that corresponds to the elements, e.g. examples or bins, that are covered (or uncovered, if covered == false) by the condition, as well as the sum of the weights of all covered elements.
