Because the most flexible and competent adaptive systems available to us are nervous systems, I'm interested in artificial neural networks and computational neuroscience. I'm most fascinated by the construction of novel architectures and algorithms that enable us to understand and attack previously unassailable problems, and to understand previously mysterious aspects of nervous system function.<p> To be specific, right now I have a few research topics simmering on the front burner:<ul> <li><em>Blind source separation:</em> I'm working on better and more modular and incremental methods to solve the cocktail party problem, both in the classic (linear square mixing matrix) and in the more difficult (fewer microphones than sources) cases. <p> <li><em>Reinforcement learning in a weakly adversarial domain:</em> In the real world, one's actions modify the world, typically to the detriment of similar actions in the future. I'd like to understand how to perform as well as possible, under the circumstances. <p> <li><em>Neural information and coding:</em> How is information represented and transformed in the nervous system? How are these representations acquired and adapted? <p> <li><em>Egomotion:</em> The process of estimating a camera's motion efficiently, reliably, robustly, and using beautiful mathematics. <p> <li><em>Neural networks:</em> Learning algorithms, generalization, relations to other techniques, handling time and domain drift in a principled fashion, unsupervised learning, information theory.</ul><p> A secondary interest of mine is in programming systems, especially advanced programming language design and implementation. There are a number of deficiencies in current advanced programming languages that hinder their application to scientific computation, and I would enjoy participating in an effort to remove these stumbling blocks.<hr><ADDRESS><!WA0><a href=http://www.cs.unm.edu/~bap/index.html>Barak Pearlmutter</a> <BR><!WA1><A HREF="mailto:bap@cs.unm.edu">bap@cs.unm.edu</A></ADDRESS></body></html>⌨️ 快捷键说明
