Ray Solomonoff

Also known as Raymond J. Solomonoff

Ray Solomonoff was a researcher in inductive inference who attended the 1956 Dartmouth Summer Research Project on Artificial Intelligence. He invented algorithmic probability in 1960, a theorem that launched Kolmogorov complexity and algorithmic information theory. "A Formal Theory of Inductive Inference" appeared in Information and Control in 1964. In 1985 he analyzed a likely evolution of AI and gave a formula for when it would reach the Infinity Point. He received the first Kolmogorov Award in 2003 and died in 2009 in Cambridge, Massachusetts.
