But it is not necessary clear whether the concept that is learned in the Webbname \Probably Approximately Correct" comes from the fact that we want a hypothesis that is approximately correct ( -good) with high probability (namely 1 ). The probability is taken over the choice of S, which will determine which hthe algorithm chooses. This is a reasonable goal because there is always a small chance that the test data will ...
