Default Q3 clarifications

What does "If there is overfitting," mean in Q3? Does it mean "In order to determine if overfitting has occurred"?

In option d) does "comparing the values of (Eout - Ein)" imply that there are at least two values of diff = (Eout-Ein)? and do they correspond to different hypotheses?

"If there is overfitting" just means that overfitting occurred in a particular learning situation. In [d], we would indeed be comparing two values that correspond to two different hypotheses.

For part d) do we assume that the values of Eout-Ein are for the same N, number of examples?

Yes, for the same training data set {\cal D}.

Does part d) mean that we only have access to values of Eout-Ein and not to the values of Ein or Eout?
