How Computers Can Teach Themselves to Recognize Cats

Today, the technique is used in everything from Google image searches to Facebook’s newsfeed algorithms. The feline recognition feat was accomplished using “deep learning,” an approach to machine learning that works by exposing a computer program to a large set of raw data and having it discover more and more abstract concepts. “What it’s about is allowing the computer to learn how to represent information in a more meaningful way, and doing so at several levels of representation,” said Yoshua Bengio, a computer scientist at the University of Montreal in Canada, who co-authored an article on the subject, published today (May 27) in the journal Nature.
