At the core of AIXI is Solomonoff induction, a way of using infinite computing power to probabilistically predict binary sequences with (vastly) superintelligent acuity. Solomonoff induction proceeds roughly by considering all possible computable explanations, with prior probabilities weighted by their algorithmic simplicity, and updating their probabilities based on how well they match observation
