Artificial Intelligence
Intelligent?
What is intelligence? l computational part of the ability to achieve goals in the world
somewhere, something went wrong
What is AI? l l Computational models of human behavior? Computational models of human “thought” process? Computational systems that behave intelligently? Computational systems that behave rationally !
Rationality: l Perceiving the world around it, – – l a rational agent selects an action to maximize the performance measure Using – – Evidence provided in perception sensors Built in knowledge of the agent
Applications of AI l l l Video games, Robocup, NERO Theorem proving Speech recognition Understanding natural language (stories) Machine translation (English-Russian) Robotics (Computer vision)
Machine translation l The spirit is willing but the flesh is weak
English – Russian - English l The spirit is willing but the flesh is weak l The vodka is strong but the meat is rotten
AI applications (contd. ) l l l Driving autonomous vehicles Tactical guidance system for military aircraft Satellite meta command system Automatic operation of trains Robots for micro-surgery
AI in electrical gadgets l l l l 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
Decision support systems l l l l 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
AI pioneers l Alan Turing(1912 -1954) – – l Marvin Minsky (MIT) – l Father of computer science Turing test for AI Built first Neural network computer SNARC John Mc. Carthy ( Stanford University ) – Developed LISP, AI programming language
