The rapidminer operator manual provides only the following description for "Weight by Rule" operator. However, no reference is given for its depth understanding. Please advise any document or article.
The Weight by Rule operator calculates the weight of attributes with respect to the label attribute
by constructing a single rule for each attribute and calculating the errors. The higher the weight
of an attribute, the more relevant it is considered. Please note that this operator can be only
applied on ExampleSets with nominal label.
Thanking you in advance.
