  1. Artificial Intelligence

  2. Intelligent?

  3. What is intelligence? • computational part of the ability to achieve goals in the world

  4. somewhere, something went wrong

  5. What is AI? • Computational models of human behavior? • Computational models of human “thought” process? • Computational systems that behave intelligently? • Computational systems that behave rationally !

  6. Rationality: • Perceiving the world around it, • a rational agent selects an action • to maximize the performance measure • Using • Evidence provided in perception sensors • Built in knowledge of the agent

  7. Applications of AI • Video games, Robocup, NERO • Theorem proving • Speech recognition • Understanding natural language (stories) • Machine translation (English-Russian) • Robotics (Computer vision)

  8. Machine translation • The spirit is willing but the flesh is weak

  9. English – Russian - English • The spirit is willing but the flesh is weak • The vodka is strong but the meat is rotten

  10. AI applications (contd.) • Driving autonomous vehicles • Tactical guidance system for military aircraft • Satellite meta command system • Automatic operation of trains • Robots for micro-surgery

  11. AI in electrical gadgets • Navigation system for automatic cars • Cruise control for automobiles • Single button control of washing machines • Camera autofocus • Back light control for camcorders • Auto motor control of vacuum cleaners • Camera aiming for sporting events

  12. Decision support systems • Medical reasoning systems • Planning rocket launching, large assemblies • Intelligent tutoring systems • Fault diagnosis in power plants • Direct marketing • Fraud detection for finance • Stock market predictions

  13. AI pioneers • Alan Turing(1912-1954) • Father of computer science • Turing test for AI • Marvin Minsky (MIT) • Built first Neural network computer SNARC • John McCarthy ( Stanford University ) • Developed LISP, AI programming language
