"Making a Robotic Dog See and Hear"







Abstract

Why is it that if computers have gotten so much faster and cheaper, they have not become any better at understanding what we want them to do? Some of the tasks we take for granted such as vision and language are still too difficult for the latest supercomputers to handle. To us, a picture may be worth a thousand words, but to a machine it's just a seemingly random jumble of numbers. How can we program computers to process this kind of information? Algorithms that mimic the way our brains compute and learn may be the answer. We'll see some examples of such biologically inspired computation applied to controlling a small robot dog.

Biography

Dan Lee studied physics at Harvard and MIT before coming to Bell Laboratories in 1995. He is now a member of the technical staff in the Biological Computation department, trying to understand the general principles that biological systems use to process and organize information. He works on applying that knowledge to building better artificial systems for vision, speech, language, and data communications. Besides playing with his robots, he enjoys ice hockey, scuba diving, and automating the apartment for his wife and their cat.
