From the article:
- Thomas Serre and his colleagues at the Massachusetts Institute of Technology have built a computer processing system that tries to work in this general way. Among the tasks that computers are bad at is recognising broad categories of images. Tell one to search for something specific, such as a rectangle or even a human face, and it can make a reasonable fist of the task. Ask it to find “animals” among photographs of dragonflies, trees, sharks, cars and monkeys, and it falls over. Indeed a monkey—or even a human baby—would leave it in the dust.
That, at least, was how it used to be. But as Dr Serre describes in this week's Proceedings of the National Academy of Sciences, his computer handles this problem rather well. In a recent test it even did a little better than humans.
