Maximum a Posteriori Estimation by Search in Probabilistic Programs

Filed under: Artificial Intelligence, Computer Science, Machine Learning — dvd @ 11:33 pm

Paper, slides, and poster as presented at SOCS 2015.

We introduce an approximate search algorithm for fast maximum a posteriori probability estimation in probabilistic programs, which we call Bayesian ascent Monte Carlo (BaMC). (more…)

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An early workshop paper, superseded by current research but still relevant, slides, and a poster.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