ClassifierAttributeEval :
Evaluates the worth of an attribute by using a user-specified classifier.
class
CorrelationAttributeEval :
Evaluates the worth of an attribute by measuring the correlation (Pearson's)
between it and the class.
Nominal attributes are considered on a value by value basis by treating each
value as an indicator.
class
GainRatioAttributeEval :
Evaluates the worth of an attribute by measuring the gain ratio with respect
to the class.
GainR(Class, Attribute) = (H(Class) - H(Class | Attribute)) / H(Attribute).
class
InfoGainAttributeEval :
Evaluates the worth of an attribute by measuring the information gain with
respect to the class.
InfoGain(Class,Attribute) = H(Class) - H(Class | Attribute).
class
OneRAttributeEval :
Evaluates the worth of an attribute by using the OneR classifier.
class
Performs a principal components analysis and
transformation of the data.
class
ReliefFAttributeEval :
Evaluates the worth of an attribute by repeatedly sampling an instance and
considering the value of the given attribute for the nearest instance of the
same and different class.
class
SymmetricalUncertAttributeEval :
Evaluates the worth of an attribute by measuring the symmetrical uncertainty
with respect to the class.
class
Abstract unsupervised attribute evaluator.
