Path Finding under Uncertainty through Probabilistic Inference

An early workshop paper, superseded by current research but still relevant, slides, and a poster.

Abstract

We introduce a new approach to solving path-finding problems under uncertainty by representing them as probabilistic models and applying domain-independent inference algorithms to the models. (more…)

Anglican the Probabilistic Programming Concept

Filed under: Computer Science, Machine Learning — dvd @ 1:44 am

Anglican is a probabilistic programming language, or better yet, a concept, living in symbiosis with Clojure. Anglican stands for Church of England (because we are here in Oxford). To create your Turing-complete probabilistic models, clone anglican-user and hack away. Or, look at cool examples.

Old Job Talk Slides

Found my own slides from a talk I gave a year ago, about rational meta-reasoning. Do they seem interesting to me because I have degraded during this year?

Poster for IJCAI-2011

Filed under: Computer Science — dvd @ 4:37 pm

I am having the pleasure of preparing a poster for IJCAI 2011, for the first time in my life. Both the IJCAI and a poster. Fiddling with PowerPoint or Illustrator is painful. Beautiful slides can be prepared with S5 using HTML and CSS; a poster in HTML and CSS is also worth a try.

Here is my HTML and CSS conference poster. Topics zoom in and out when you click on them. A PDF version for printing is also two clicks away in a decent web browser (that is, Mozilla Firefox).

I am less fearful of preparing conference posters now.
