Publications


We strive to make our research reproducible. This means that when possible we provide a pdf version of the paper, additional details, source code, example data used to generate the results, provide updates / bug fixes, and are responsive to questions. Click on the title links to go to that paper's page. Of course, if you use a paper or its code in your research, please add a reference as appropriate to your publications.

Note, as of 2011 IEEE policy no longer allows authors to post final version of their papers on their own websites. The prepreints posted here however are equivalent or in some cases better than the officially published versions.
