Voting by the Weight of Evidence Measure

The final method will use a variant of the weight of evidence measure, described in gif, to vote. The method there cannot be used directly, since the weight of evidence must be calculated or given in the rules for each attribute value describing a class. The rules available from RGEN have accuracies and numbers for the combination of several attributes, and not for each attribute alone. We will instead use the J-measure from Equation gif as shown in Figure gif.

will be equal to the accuracy of the current rule. will be given in the rule file as well, and is common for all rules with the same decision.
