INTRODUCTION HISTORY SUB-FIELDS ARTIFICIAL INTELLIGENCE IN THE FUTURE Intelligence in machines especially in computers Computer programs equipped with some features of human intelligence Uses fuzzy logic to decide AIM: To reach exact level of human intelligence Alison Turing is the father of idea Artificial neural cells are invented by taking brain as the pattern Improved programs could not be successful in the problems of real world CASE 2 CASE 1 A program that works as psychologist One of the unsuccessful programs Human: My dog’s mother died recently Eliza: Tell me more about your mother Human: I'm having trouble sleeping. Eliza: Why do you say you are having trouble sleeping? Human: Because I can't sleep. Eliza: Is it because you cannot sleep that you came to me? A test to measure the level of success of an artificial intelligence-based program GAME PLAYING SPEECH RECOGNITION UNDERSTANDING NATURAL LANGUAGE COMPUTER VISION EXPERT SYSTEMS Capability of looking at hundreds of thousands of positions at the same time Dominant over human in terms of speed and knowledge Examples: Chess, today’s high-technology games Improved ability to identify sound thanks to combination of: speaker's mouth position traditional audio pattern data Programmed by: CASE 1 Human: My dog's mother died recently. ALICE: Did you grow up around animals? CASE 2 Dr. Richard WALLACE from Carnegie University Human: Where is Sue's nose when Sue is at her house? ALICE: Where it belongs. I will try to find out. Computer’s ability to see Searches a great deal of possible conditions by using knowledge of the world Programs designed to solve expert problems by using knowledge and inference EXPERT SYSTEMS The result is undefinete Use expert knowledge Can solve a new problem by using its own knowledge Use artificial intelligence languages like lisp, prolog PROCEDURAL PROGRAMS The result is definite Based on simple algorithms Dependant on a new compilation to solve a new problem Programming languages such as Pascal,Basic is used Mycin Cancer, Me?? GermAlert FACTS (Finding Appropriate Clinical TrialS) Oncolog INCREASED AVAILABILITY REDUCED COST PERMANENCE INCREASED RELIABILITY REDUCED DANGER FAST RESPONSE Combination of these sub-fields with minimum failure is the target http://www.psych.utoronto.ca http://www.computer.privateweb.at http://www-formal.stanford.edu http://www.pandorabots.com http://www.akademiyapayzeka.com http://www.members.tripod.com http://www.yapay-zeka.org http://www.acm.org http://en.wikipedia.org http://rationale.csail.mit.edu http://video.google.com/computer+versus http://distancelearning.ksi.edu http://www.alicebot.org/
