Judea Pearl receives Turing Award
Judea Pearl won the 2011 ACM Turing AwardThe ACM's highest honor in computing — often called the Nobel Prize of computer science. for probabilistic and causal reasoningStep-by-step logical thinking in AI models — chain-of-thought before answering hard problems. in AI.
What it was for
Pearl's Bayesian networks and do-calculus gave AI a rigorous framework for uncertainty and causation — underpinning modern recommendation systems, diagnostics, and the current 'causal AI' movement.
