Research Publications

My publications are grouped into the following topic areas:

• Low-vision Navigation
• Distributed Agents
• POMDPs
• NLP
• Non-refereed Papers

These are papers that came out of a collaboration with Brian Stankiewicz in the Psychology Department of the University of Texas at Austin. We began our collaboration in the Summer of 2004 and I spent one semester in his lab as a Research Fellow in the Spring of 2005.

These papers are from the work I did with collaborators I first worked with at MCC on distributed agent systems. After the demise of MCC, many of my colleagues moved to Telcordia and continued working on similar research projects. These papers reflect work I participated in at MCC and Telcordia.

POMDP is an acronym for "Partially Observable Markov Decision Process". This is a probabilistic mathematical model that can be used to make decisions under many forms of uncertainty. It has applications in Machine Learning and Operations Research. This was the topic of my doctoral thesis. You can view a tutorial and go much deeper on the subject at the POMDP.org Web Site which I created and maintain.

I took a graduate-level course on Natural Language Processing (NLP) with the esteemed Prof. Eugene Charniak. In addition to teaching the basics of NLP, Prof. Charniak had us participate in a research project. The culmination of our collective work led to this publication, which I believe was part of a bigger research thread Prof. Charniak had been pursuing.

The POMDP survey paper is something I just never got around to submitting for publication while the other two are a more in-depth treatment of topics related to some of the published papers (above).
