    ARTIFICIAL INTELLIGENCE

    fThe branch of computer science concerned

    with making computers behave or think like

    humans.

    HISTORY OF AI

    f In 1956 John McCarthy regarded as the father of AI,

    organized a conference to draw the talent and expertise of

    others interested in machine intelligence for a month of

    brainstorming. The Dartmouth AI Conference broughtabout those involved in research in AI: John McCarthy

    (Dartmouth), Marvin Minsky (Harvard), Nathaniel

    Rochester (IBM), and Claude Shannon (Bell Telephone Lab)

    brought together researches in computers, natural language

    processing, and neuron nets to Dartmouth College.

    HISTORY OF AI

    fIn 1956, John McCarthy designed LISP, the

    first AI programming language.

    fIn 1962, Tim Hart and Mike Levinimplemented the first LISP compiler at MIT

    in 1962 for the IBM 704.

    CURRENT SCENARIO IN AI

    fCurrently, no computers exhibit full artificial

    intelligence ; that is, are able to simulate human

    behavior.

    fThe greatest advances have occurred in the field ofgames playing. The best computer chess programs are

    now capable of beating humans. In May, 1997, an IBM

    super-computer called Deep Blue defeated world chess

    champion Gary Kasparov in a chess match.

    CURRENT SCENARIO IN AI

    fIn the area of robotics, computers are now widely

    used in assembly plants, but they are capable only

    of very limited tasks.

    fCurrently, robots have great difficulty identifying

    objects based on appearance or feel, and they still

    move and handle objects clumsily.

    CURRENT SCENARIO IN AI

    fIn the early 1980s, expert systems were believed to

    represent the future of artificial intelligence and of

    computers in general.

    fTo date, however, they have not lived up to

    expectations. Many expert systems help human

    experts in such fields as medicine and engineering,

    but they are very expensive to produce and are

    helpful only in special situations.

    CURRENT SCENARIO IN AI

    fToday, the hottest area of artificial intelligence is

    neural networks, which are proving success in a

    number of disciplines such as voice recognition and

    natural-language processing.
