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.

Re: Q3 clarifications

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 .

Re: Q3 clarifications

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