Summary

Artificial intelligence (AI) is the construction of intelligent, computer-based systems. An AI system may play a game, solve problems, or act as a pet. AI systems tend to use heuristics, a search strategy, or lookup tables to avoid an exhaustive search of the possible solutions.

Chess is the classic game for AI. Attempts at Go are less successful. (cbb 6/06)

Subtopic: emergent behavior up

Quote: the real mystique of computers is their elaborate behavior from limited capabilities [»kentW_1978]

Subtopic: AI as problem solving up

Quote: one form of artificial intelligence consists of solving problems that have required human intelligence [»parnDL12_1985]
Quote: we need AI because intelligence is used to reduce intractable problems to manageable size; how do we do this? [»strzT5_1988]

Subtopic: AI as imitating intelligence up

Quote: another form of artificial intelligence uses heuristic or rule-base programming to solve a problem like a human seems to solves it

Subtopic: AI as assistant up

Quote: Vellum has a Drafting Assistant to suggest relationships and commands such as 'on', 'intersection', 'tangent'; a use of "animated language" [»tognB_1992]

Subtopic: AI as symbol manipulation up

Quote: AI assumes that one can explain the high-level traffic of symbol activations in its own terms, without neural events [»hofsDR_1979]
Quote: cognitive science rests on the assumption that cognitive terms can be related independently of other descriptive systems [»pylyZW_1986]

Subtopic: AI as string transformation up

Quote: use GAWK for AI because any logic merely defines how strings can be transformed into other strings; GAWK is designed for string transformation [»louiRP8_1996]

Subtopic: AI as novice up

Quote: the mental processes of a novice are easily imitated by a computer; outperforms novice because of more rules and context-free elements [»hallH_1992]

Subtopic: AI as brute force up

Quote: Scrabble is very fast but not smart; still achieves resounding victories almost all human players [»appeAW5_1988]

Subtopic: AI as physical up

Quote: to avoid delusion, should build complete, intelligent systems with real sensing and real action; enhance incrementally [»brooRA1_1991]
Quote: physical grounding hypothesis: an intelligent system must be grounded in the physical world with appropriate sensors and actuators [»brooRA6_1990]
Quote: artificial knee with automatic knee locking reflex on contact with ground [»bekeGA4_1986]

Subtopic: random search up

Quote: software must have internal regularies which can be found by random search
Quote: random search of scheduling solutions more effective than complete search; master or collar variables determine the behavior [»menzT1_2007]
Quote: solve large N-queens problems using random search; up to board size 26 [»menzT1_2007]

Subtopic: collar variables up

Quote: collar variables are variables that determine the behavior of the rest of the system [»menzT1_2007]

Subtopic: learning up

Quote: the goal of temporal difference methods is to match the learner's current prediction for a pattern with the next prediction at the next time step [»tesaG3_1995]
Quote: a program could learn if a higher-level program changed its evaluation functions according to the results of games played [»shanCE3_1950]
Quote: if could teach computers, they could digest the world's libraries and achieve superhuman effectiveness; basic goal of AI [»schwJ_1987]
Quote: a research program for AI is to hand-code a broad knowledge base, then acquire knowledge through reading, and finally learn by discovery [»lenaDB1_1991]
Quote: a program could randomly vary its evaluation function and select those variations that perform best
Quote: produce a thinking machine by imitating each part and letting it roam the countryside; too slow and too large to be practical [»turiAM9_1947]
Quote: Turing created a universal machine by training, on paper, an unorganized machine with rewards and punishments; circular memory of 64 squares [»turiAM9_1947]

Subtopic: chess up

Quote: a paper machine for playing chess acts as if it were alive; it is difficult to distinguish from a rather poor chess player [»turiAM9_1947]
Quote: want to represent chess as numbers and operations on numbers, and to reduce strategy to a sequence of computer orders [»shanCE3_1950]
Quote: computers have applications in matrix operations, differential equations, logical problems including chess and draughts, commercial and industrial subjects, fault diagnosis, programming, and pure mathematics [»ferr8_1952]
Quote: play chess by maximizing and minimizing the value of the current position; computed by adding terms for such properties as doubled pawns [»shanCE3_1950]
Quote: a chess program needs functions to determine stable positions (no pieces en prise) and potentially useful moves [»shanCE3_1950]
Quote: a chess program should play a fairly strong game, at speeds comparable to humans
Quote: can use statistical variations during the chess opening and can play by the book, like masters [»shanCE3_1950]

Subtopic: remote control up

Quote: formal analysis of a plan execution module for NASA's Remote Agent; first complete, AI control of a space-craft [»haveK8_2001]
