Variational Approximations between Mean Field Theory and the Junction Tree Algorithm
Wim Wiegerinck
Recently, variational approximations such as the mean field approximation have received much interest. We extend the standard mean field method by using an approximating distributi…
IPF for Discrete Chain Factor Graphs
Wim Wiegerinck, Tom Heskes
Iterative Proportional Fitting (IPF), combined with EM, is commonly used as an algorithm for likelihood maximization in undirected graphical models. In this paper, we present two i…
Stochastic Optimal Control in Continuous Space-Time Multi-Agent Systems
Wim Wiegerinck, Bart van den Broek, Hilbert Kappen
Recently, a theory for stochastic optimal control in non-linear dynamical systems in continuous space-time has been developed (Kappen, 2005). We apply this theory to collaborative…
Risk Sensitive Path Integral Control
Bart van den Broek, Wim Wiegerinck, Hilbert Kappen
Recently path integral methods have been developed for stochastic optimal control for a wide class of models with non-linear dynamics in continuous space-time. Path integral method…
