Resources for learning about AIXI, Solomonoff induction, and related topics.

Historical Foundations

Ray Solomonoff (1926–2009) founded algorithmic probability—the theory that underlies Solomonoff induction and, ultimately, AIXI. His universal prior M(x) formalizes Occam’s razor: simpler hypotheses receive higher prior probability.
