Description copied from interface: IClassificationNonconformityFunction

Computes the non-conformity score for the instance x with the target y.

Specified by:

calculateNonConformityScore in interface IClassificationNonconformityFunction

Specified by:

calculateNonConformityScore in class ClassifierNonconformityFunctionBase

Parameters:

x - the instance.

y - the target/class/label.

Returns:

the non-conformity score. Large means less conforming.
