That depends on *what* you're trying to predict. Let's say you're
searching the inference space of axiomatic derivations in ZF set theory.
No matter what kind of bizarre probabilistic searches you use to
control your inferences, if the space is of legitimate derivations, you
can remain confident that the result is a legitimate proof. This is the
prediction that matters, even if you can't predict how exactly the proof
