Right now the TensorFlow gradient explainers do not implement the
_generate_counterfactuals
method from theBaseExplainer
class. This means that:1) You cannot instantiate object of class
DiceTensorFlow(1/2)
without replacing the__class__
of another method, because it is not a valid child
of
ExplainerBase
.2) By overriding the parent
generate_counterfactuals
method, the two classes bypass any validation steps
that would normally be carried out by the base class
(e.g. checking that the number of CF queries is non-negative).
I believe this to be in error, is it on purpose?
