CSE 471/598 Introduction to Artificial Intelligence Fall 2002 Introduction • You, • TA: Ryan Holmes, GWC xxx MTH 1-2pm, [email protected], and • me [email protected] (http://www.public.asu.edu/~huanliu) CSE 471/598, H. Liu 2 The course • What is AI (many definitions of AI) – One definition: a field to enable computers with human-level intelligence with attempts to understand intelligent entities. • What is this course about – understand ourselves better – build automated intelligent agents – improve problem solving skills CSE 471/598, H. Liu 3 The course (2) – Projects in Lisp (30%, 2*15%) – Exam(s) (2X20%) – Homework (30%, 5*6%) – Late hand-in penalty – Academic integrity CSE 471/598, H. Liu 4 Plan • Text Book: AI - A Modern Approach • 15 weeks - about 13-15 chapters • One major subject per week TIP Try to keep up and avoid catch-up CSE 471/598, H. Liu 5 Plan (2) • Major topics – Intelligent agents – Problem solving – Knowledge and reasoning – Acting logically – Uncertainty – Learning CSE 471/598, H. Liu TIP Comprehend the topics with your common sense 6 Welcome to this class! • We will work together throughout this semester. • Questions and suggestions are most welcome. CSE 471/598, H. Liu 7 Introduction of AI and LISP - Gearing up for a fun semester about intelligent agents What is AI (2) • Acting humanly: The Turing test • Thinking humanly: Cognitive modeling • Thinking rationally: Syllogisms, Logic • Acting rationally: A rational agent CSE 471/598, H. Liu 9 Foundations of AI • Philosophy (428 B.C. - Present) - reasoning and learning • Mathematics (c. 800 - Present) - logic, probability, decision making, computation • Psychology (1879 - Present) - investigating human mind • Computer engineering (1940 - Present) - ever improving tools • Linguistics (1957 - Present) - the structure and meaning of language CSE 471/598, H. Liu 10 Brief History of AI • Gestation of AI (1943 -1956) • Early enthusiasm, great expectations (1952 1969) • AI facing reality (1966 - 1974) • Knowledge-based systems (1969 - 1979) • AI - an industry (1980 - 1988) • Sober and maturing AI CSE 471/598, H. Liu 11 Some examples of AI applications • Smart bombs • Biometrics • Deep Blue • Communications (email, word processor) • Gaming • Intelligent houses • Intelligent appliances • Auto driving from E to W • RoboCup • Consumer protection CSE 471/598, H. Liu 12 Refresher for LISP • What is it? – ANSI Common Lisp, Paul Graham, Prentice Hall • Input (e.g., terminal, files) • Output (e.g., files, printing) • Processing (various operations) • How to run it?
