Marty Baylor: A Dynamical Systems Approach to the Cocktail Party Problem


"Have you ever been at a noisy party and been able to pick out what the person in front of you is saying? If so, then you are intimately aware of the fact that your brain is able to solve the cocktail party problem. How does your brain separate one signal from a mixture of signals? I have no idea, but I have been working with a half optical, half electronic system that is able to mimic that behavior. The system uses a special holographic crystal in a feedback loop to solve the cocktail party problem without any a priori information about the unmixed signals or how they are mixed together. By analyzing the dynamics of the feedback loop, we have discovered that under cer- tain conditions the feedback loop likes to separate signals. I invite you to come and find out about this truly fas-cinating system and hear some of the audio demosdemonstrating its signal-separating prowess. I willalso briefly discuss my ef-forts to miniaturize useful optical systems like this us-ing light-sensitive polymersso that they can be used in everyday life." - Baylor
