  1. I Know it’s an IdiotBut it’s MY artificial idiot! Vint Cerf Google

  2. Warning! • I am a computer scientist • But I am not an AI expert • So I don’t really know what I am talking about • But that never stopped me before!

  3. So What is AI? • Analytic Programming • Move Trees in Games; Decision Trees • Alpha-Beta Pruning • Expert Systems • Edward Feigenbaum, Joshua Lederberg: DENDRAL • Bayesian Analysis • Conditional Probabilities • Decision making with partial information

  4. Layman’s Definition • If it doesn’t work all the time, it’s AI • If it works, it’s engineering

  5. Neural Networks • Outputs = sum of inputs*weights

  6. Neural Networks (2) • Apply inputs • Calculate actual vs desired output • Back Propagate Proportionate squared error to adjust weights • Repeat to minimize error • Classification, Recognition, Decision Making

  7. Language Translation • Dictionary Lookup • English/Russian • “Out of Sight; Out of Mind” • “Invisible Idiot” • Statistical Phrase Matching • Large corpus of document pairs • Significant jump in translation quality • Application of sentence structure, semantics • Most recent results w/neural networks

  8. Language Translation

  9. Games (1) • Programming to achieve human-like result • Checkers • Arthur Samuel: coined “Machine Learning” 1959 • Search Tree; Alpha-Beta Pruning; Board Position • Chess • IBM Deep Blue vs Kasparov: 1997 (3 ½ - 2 ½) • 1st Game, Move 44 – bug – superior intelligence • Kasparov wins first game but loses second

  10. GO!

  11. AlphaGo • DeepMindvs Lee Sedol • 4 games out of 5 • Move 37 in Game 1 • 150 layer neural network • Tensor Processing Unit (TPU) • Google Datacenter Cooling: 40% electricity reduction

  12. Self Driving Car • Video removed (has been captured in the recorded video of the presentation)
