| Sumario: | In the current issue of the Proceedings of the National Academy of Sciences, Dr. Thomas Serre describes how he and his colleagues at the Massachusetts Institute of Technology have built a computer that can recognize classes of things as accurately as a person can. Although computers are very good at solving specific problems, they have difficulty when it comes to working in a general way, for example in recognizing broad categories of images. However, Dr. Serre's computer, which is based on a model that closely imitates the functioning of the ventral visual pathway in the human brain, has proved the equal of human volunteers in distinguishing photographs containing animals from those without.
