Judea Pearl

Professor of Computer Science, UCLA

JUDEA PEARL, professor of computer science at UCLA, has been at the center of not one but two scientific revolutions. First, in the 1980s, he introduced a new approach to artificial intelligence called Bayesian networks. This probability-based model of machine reasoning enabled machines to function in a complex, ambiguous, and uncertain world. Within a few years, Bayesian networks completely overshadowed the previous rule-based approaches to artificial intelligence.?

Leveraging the computational benefits of Bayesian networks, Pearl realized that the combination of simple graphical models and probability (as in Bayesian networks) could also be used to represent cause-effect relationships. The significance of this discovery far transcends its roots in artificial intelligence. His principled, mathematical approach to causality has already benefited virtually every field of science and social science, and promises to do more when popularized.

Pearl has written three highly influential scholarly books: Heuristics (Addison-Wesley, 1984), Probabilistic Reasoning in Intelligent Systems (Morgan-Kauffmann, 1988), and Causality: Models, Reasoning, and Inference (Cambridge University Press, 2009). He is a winner of the Alan Turing Award, often considered the equivalent of the Nobel Prize for computer science. He is a member of the U.S. National Academy of Sciences, and was one of the first ten inductees into the IEEE Intelligent Systems Hall of Fame. He has received numerous awards and honorary doctorates, including the Rumelhart Prize (Cognitive Science Society), the Benjamin Franklin Medal (Franklin Institute) and the Lakatos Award (London School of Economics). He is the founder and president of the Daniel Pearl Foundation.

That Aenesid��mus held this view is stated as a fact by Sextus, whose testimony is here corroborated by Tertullian, or rather by Tertullian��s informant, Soranus. We find, however, that Zeller, who formerly accepted the statement in question as true, has latterly seen reason to reject it.188 Aenesid��mus cannot, he thinks, have been guilty of so great an inconsistency as to base his Scepticism on the dogmatic physics of Heracleitus. And he explains the agreement of the ancient authorities by supposing that the original work of Aenesid��mus contained a critical account of the Heracleitean theory, that this was misinterpreted into an expression of his adhesion to it by Soranus, and that the blunder was adopted at second-hand by both Sextus and Tertullian.299 He himself had never dreamed how it irked her until now. It was many years since he had been in the East, not, indeed, since Felipa had been a small child.[Pg 160] Keeping his promise to Cabot, as he understood it, had left him little for such pleasures as that. But he had done his duty then; he would do it again, and reap once more what seemed to him the inevitable reward, the reward which had been his all through his life,��sheer disappointment, in all he prized most, ashes and dust. [Pg 170] And he succeeded in seeing Felipa. It was most unexpected. He had believed her to be in Stanton, a good many hundred miles away. But Landor having been sent at once into the field, she had come on to Grant to visit the Campbells, who were again stationed there. He met her face to face only once, and he measured with one quick look all the changes there were between the girl of ten years before and the woman of to-day. The great, sad pity that rose within him, and seemed to grasp at his throat chokingly, was the best love he had felt for her yet. It wiped out the wrong of the short madness in the cave's mouth. She drew her horse down to a gallop, and the jar of the changed gait made her moan. There was no haste now. Her own men had come upon the desperadoes and there was a quick volley. And ahead, riding fast toward her from the top of a little rise, was a man on a white horse��her husband, she knew. It amused and pleased the General to see Shorty take into his hands the administration of military etiquette; but one day, when he was accompanying the General on a tour of inspection, and walking stiffly at the regulation distance behind, a soldier drunk enough to be ugly lurched past, muttering some sneers about "big shoulder-straps." "Tell 'em not to sweat. Just hold their horses. We'll be over presently," shouted the others, with yells of laughter. "What else do you see?" "From your loving At twelve the poll stood at a hundred and one for the Captain and sixty-five for the Colonel. The Tories were getting desperate��they threw into the crowd handbills wet from the printers, declaring that MacDonald's toll-gate should not stand an hour after he was elected. But the crowd only sang derisively: "My lord," replied Edith, rising from her seat and stepping forward a few paces, "Margaret Holgrave has little leisure from attending to the household of her husband. There are abundance of skilful sempstresses; and surely the Baron de Boteler would not require this young woman to neglect the duty she has taken upon herself." "No," said Holgrave. "Now you speak of the boy, I will not leave this place. Let him live and toil, and suffer, and��" "Aye, ye may soon sleep your last sleep. They will have at ye in the morning; for the proud barons are gathering their might; but, by St. Nicholas! I may do something yet. Yes, there will be more blood��I see it;��I must have an order to behead the lords; and then, if Richard will be king of the commons, and no more lords or bondage, father John himself could not wish for more."
