Is the Under Liquid Date Distribution Changing?

The model was trained only to know the existence of digits zero through eight. And then as suddenly we see an a nine, which is something it hasn't seen before,. We want to kind of see, does the model behave differently when it sees this digit? Obviously, because it doesn't know what a nine is. But we can see by the fact that maybe it behaves differently in terms of its confidence. That's one of the ways we try to make this very general gote. Sometimes threes and fives get confused. O remember, and sevens.
