Sounds like compelling technology. 

First published last year, the program and the accompanying study is the work of Fei-Fei Li, director of the Stanford Artificial Intelligence Laboratory, and Andrej Karpathy, a graduate student. Their software is capable of looking at pictures of complex scenes and identifying exactly what's happening. A picture of a man in a black shirt playing guitar, for example, is picked out as "man in black shirt is playing guitar," while pictures of a black-and-white dog jumping over a bar, a man in a blue wetsuit surfing a wave, and little girl eating cake are also correctly described with a single sentence. In several cases, it's unnervingly accurate.
