George Johnson of the NY Times on Algorithms

George, as you may recall, moderated the recent Decade of the Mind conference at Krasnow in May. Here is his take on where AI is these days: human brains mated with computer algorithms are powerful tools.

Money quote:

What is spreading through the Web is not exactly artificial intelligence. For all the research that has gone into cognitive and computer science, the brain’s most formidable algorithms — those used to recognize images or sounds or understand language — have eluded simulation. The alternative has been to incorporate people, with their special skills, as components of the Net.

Go to Google Image Labeler (images.google.com/imagelabeler) and you are randomly matched with another bored Web surfer — in Korea, maybe, or Omaha — who has agreed to play a game. Google shows you both a series of pictures peeled from the Web — the sun setting over the ocean or a comet streaking through space — and you earn points by typing as many descriptive words as you can. The results are stored and analyzed, and through this human-machine symbiosis, Google’s image-searching algorithms are incrementally refined.
