HVAC Control in the New Millenniumthe time is built into the gears. The digital electronic clocks have theirintelligence built into the electronic circuitry. A clock can be though aspecial-purpose machine whose task it is to keep the correct time. Someelectronic clocks can even accept spoken commands asking what time itis and respond through a speech synthesizer with the time.Turing’s TestAlan Turing was a British mathematician who proposed a classictest for machine intelligence. Turing’s test involves a room with twocomputer terminals. One of the terminals is connected to a terminal inanother room, with another human at the keyboard. The other terminalis connected to a computer in another room, with an artificial intelligenceprogram loaded in its memory.Now, use a keyboard to carry on conversations with the two terminals.If at the end of 15 minutes, you cannot tell which terminal is connectedto the human and which terminal is connected to the computer,then the computer has demonstrated some intelligence.A relatively simple program can carry on a meaningful conversationwith a human. One of these is ELIZA which pretends to be a psychotherapist.This program was written as a demonstration of artificialintelligence and can run on a personal computer. The program syntacticallytakes apart the statements made by the human and rearrangesthem as a response.The program has no learning capability and it does not understanda word the human says. The program could be firmware or built-inintelligence, since it does not change.Learning and Educable MachinesOne area of intelligence involves the ability to learn. This ability isgenerally assessed based on what one has learned. The famous study ofdogs by Pavlov shows how learning is a result of repeated cause-andeffectevents.The process of learning from one’s mistakes is demonstrated bychess or checkers game programs. All the possible moves for a playerare analyzed for the game. Only the legal moves are given to the pro-©2001 by The Fairmont Press, Inc. All rights reserved.
