An AI algorithm now proven to draw letters as well as a human
Researchers claim to have made a breakthrough
in artificial intelligence by giving machines cognitive powers similar
to humans. The team from MIT, York University and the University of
Toronto first trained an algorithm to draw characters in 50 languages by
studying the required pen strokes. Once completed, it was able to
successfully draw a new character that it had never seen before, meaning
it had essentially "learned" the skill. That might not sound
impressive, because we humans can do it easily. But so far, similar
feats have only been done by large neural networks that require huge databases of images and learn more by brute force than smarts.
Rather than a
neural network, the team used a so-called Bayesian program learning
framework. Because the algorithm is based on probability and guessing,
it's using a cognitive process like humans and not a typical rote
computer method. When the machine "drew" characters on the screen, each
one was slightly different but still identifiable like the ones we would
draw. As a result, only 25 percent of judges who compared the samples
to human-drawn characters were able to tell the difference. Author
Joshua B. Tenenbaum told the NYT
that "it's amazing what you can do with lots of data and faster
computers. But when you look at children, it's amazing what they can
learn from very little data. Some comes from prior knowledge and some is
built into our brain."
