SPIRAL out of convexity: sparsity-regularized algorithms for photon-limited imaging
The observations in many applications consist of counts of discrete events, such as photons hitting a detector, which cannot be effectively modeled using an additive bounded or Ga...

Using Linear Programming for Bayesian Exploration in Markov Decision Processes
A key problem in reinforcement learning is finding a good balance between the need to explore the environment and the need to gain rewards by exploiting existing knowledge. Much ...

Models and the locus of their truth
If models can be true, where is their truth located? Giere (e.g. 1988) has suggested an account of theoretical models on which models themselves are not truth-valued. The paper su...

A Performance Based Parametric Model for Facial Animation
In this paper we present a parametric model for facial animation and a method for adapting it to a specific person. Every facial expression can be described as a contraction or r...
