order in chaos without being overwhelmed is another major sub-division of artificial
intelligence. Most phenomena in the world are analog--in other
words, their actions are occur continuously over time. A great example of analog
devices that man has built is the tape recorder--it records every bit of sound every
second, millisecond, nanosecond, etc. Computers, on the other hand, are digital
machines in that it records data in absolute 0's and 1's. Thus, getting a
computer to filter the analog world into meaningful digital representations is a major
challenge that requires intelligence. One of the most effective ways to find meaning
in data is to find the patterns that represent it. In this way, the information can
be understood by the computer as well as be easier to store with less memory requirements.The
two major divisions of pattern recognition are machine vision and
sound. The first's goal is to get a computer to recognize
pictures so that it can recognize objects in its surroundings that would be helpful in
robotics. The latter wants to achieve a similar goal but is a primary concern with
companies that want to produce a new means in which a person interacts with a computer by
talking. |
