Correct me if I'm wrong, but doesn't PAC on real data usually just tells you that "it doesn't know the answer"? Like, it says the equivalent to: "I think this is the answer, but it might be miles off and I give it 50% it is even more than miles off." I found that it is able to give hard guarantees, by being very loose on the bounds. Do you have a real-world example where it actually gave something useful? I'm genuine curious, because I discarded it early on, but am willing to revisit it.
