General Information

My primary interests lie in statistical modeling (particularly graphical model approaches) and signal processing for pattern classification, speech recognition, language processing, machine learning, combinatorial optimization, and audio processing. I am particularly interested in temporal graphical models (or dynamic graphical models) and ways in which to design efficient algorithms for them and design their structure so that they may perform as better structured classifiers. I also have strong interests in speech-based human-computer interfaces, the statistical properties of natural objects and natural scenes, information theory and its relation to natural computation by humans and pattern recognition by machines, and computational music processing (such as human timing subtleties). I am also quite interested in high performance computing systems, computer architecture, and software techniques to reduce power consumption.

In the summer 2001, I was a leader at the JHU CSLP workshop on discriminatively structured graphical models for speech recognition based on the ideas presented in my 2000 UAI paper

I ran the 1st inference evaluation at UAI2006 this past year (2006).

Also, see the following workshop on spoken human-computer interfaces for 2007 at CHI.

I will be a general co-chair for UAI 2009 along with Andrew Ng.
