Good question, Eliezer. If the human mathematician is computable, why isn’t it already incorporated into Solomonoff Induction? It seems to me that the human mathematician does not behave like a Bayesian. Let H be the hypothesis that the input sequence is the unary encodings of Busy Beaver numbers. The mathematician will try to estimate, as best as he can, P(next symbol is 0|H). But when the next symbol turns out to be 1, he doesn’t do a Bayesian update and decrease P(H), but instead says “Ok, so I was wrong. The next Busy Beaver number is bigger than I expected.”
I’m not sure I understand what you wrote after “to be fair”. If you think a Solomonoff inductor can duplicate the above behavior with an alternative setup, can you elaborate how?
