The most progressed forms of creativity in AI is music in part because of the
low-storage requirement as opposed to visual art. Music today in the computer world
consists of the digitizing of sounds. Nowadays, the advancement of memory and
synthesizers enable computers to store a wide-range of sounds from many instruments and
then faithfully replicated them either by playing the recorded sound or by originally
synthesizing the same sound that can fool all but the most trained ears. This is the
basis of the musical instrument device interface(MIDI) that allows computers to perform
such a feat.
The next step to integrate music and computers is actually making a machine compose its
own work. Also because of the much formalization of the rules and notation regarding
its composition, music has progressed faster then any other creative medium of AI.
Much like natural language
processing, music composition forced developers to program their computers to
understand the sounds they could produce. From sound-recognition that allow
computers to distinguish individual sounds to music- recognition that allows a computer to
dissect what a group of notes mean--much like elementary music theory. A computer
that can understand what differentiates classical music from rock 'n roll and techno will
bring it closer to producing its own music either in a similar style(perhaps by generating
random notes that conform to the rules of certain kinds of music) or creating its own
style.
Even though natural language processing has still some ways to go, a few people have
created computer programs that generate poetry. With the few number of rules that
govern structured poetry like haiku's to other structures defined by the user, a computer
can string together words based on semantics and the grouping of highly-used words.
Author Raymond Kurzweil of The Age of Intelligent Machines proposes poetry as
another medium in which a variation of the Turing Test
can be applied. The Kurzweil Cybernetic Poet actually "studies" man-made
poetry and then generates its own poetry in the same style based on word-sequences.
Feeding the computer poet stanzas from people like T. S. Eliot, Percy Bysshe Shelly,
William Carlos Williams and even the author himself, the computer generated a few lines of
poetry itself. Taking a combination of computer-generated and human-generated
stanzas, Kurzweil administered a quiz to thirteen adult judges and three child
judges. All in all, the adults correctly identified 63% of the computer-made poems
from the human-made poems while children fared a bit worse at 42%. Though not
convincing statistics to pass the Turing Test, the Cybernetic Poet has achieved a lot just
by employing some simple techniques in language parsing. It is still a while before
a computer writes what it means rather than what "sounds human."(Kurzweil 376-377)
The computer has revolutionized art just as it did with music by augmenting the human
artist and allow the artist a new medium with new possibilities to produce visual art.
Because computers can manipulate complex information like pictures with ease, it
can reproduce the same image over and over or rotate the image in any angle possible.
Today, there are even 3-D art programs that allow the creation of exotic worlds and
realistic objects.
Sometimes, an artist wants to emulate real artist tools to make pictures look as if it
were painted by hand. Thus, computers need to be programmed to recognize how
different brushes produce different brush strokes, how the consistency of oil pastels
differ from chalk pastels, and how rubbing blurs a pencil-drawn line.
The mathematics and art of fractals have all benefited from the development of the
computer. Scientists have recently created realistic worlds with fractals from the
mountains to the clouds the the trees based on simple formulas. The ramifications of
fractals and 3-D modeling is that it can help a computer understand the world around it
that may be help in developing an intelligent machine.
More AI-specific applications in art is the creation of a computer that is the
artist. Harold Cohen is a professor of the Visual Arts Department at the University
of California, San Diego, created Aaron, a computer program designed to draw a botanical
garden even though it has never seen one before. Before the computer draws the
picture, it is fed information of some general characteristics of plants which it then
manipulates the height and the width of the plants to produce a variety of floral.
In addition, Aaron was given basic parameters about drawing a person and has produced
garden scenes with human figures in it.
