This week our podcast presents Luis von Ahn, assistant professor of computer science at Carnegie Mellon university. He and his team have developed what they call "Games with a purpose" to help improve computer intelligence.
The site provides what they say are "fun tasks that are easy for humans -- but beyond the capability of computers."Among them are two imaging-specific games:ESP, in which players guess what words another will use to describe an image-- which helps create descriptions of uncaptioned images.Matchin, in which players are asked which of two images they like best -- which helps computers recognize what images people prefer.
