A likelihood-based framework for the analysis of discussion threads

Gómez, Vicenç; Kappen, Hilbert J.; Litvak, Nelly; Kaltenbrunner, Andreas (Springer, 2013)

Online discussion threads are conversational cascades in the form of posted messages that can be generally found in social systems that comprise many-to-many interaction such as blogs, news aggregators or bulletin board ...
Action selection in growing state spaces: control of network structure growth

Thalmeier, Dominik; Gómez, Vicenç; Kappen, Hilbert J. (IOS Press, 2016)

The dynamical processes taking place on a network depend on its topology. Influencing the growth process of a network therefore has important implications on such dynamical processes. We formulate the problem of influencing ...
Adaptive smoothing for path integral control

Thalmeier, Dominik; Kappen, Hilbert J.; Totaro, Simone; Gómez, Vicenç (Microtome Publishing, 2020)

In Path Integral control problems a representation of an optimally controlled dynamical system can be formally computed and serve as a guidepost to learn a parametrized policy. The Path Integral Cross-Entropy (PICE) method ...
Optimal control as a graphical model inference problem

Kappen, Hilbert J.; Gómez, Vicenç; Opper, Manfred (Springer, 2012)

We reformulate a class of non-linear stochastic optimal control problems introduced by Todorov (in Advances in Neural Information Processing Systems, vol. 19, pp. 1369-1376, 2007) as a Kullback-Leibler (KL) minimization ...
Policy search for path integral control

Gómez, Vicenç; Kappen, Hilbert J.; Peters, Jan-Michael; Neumann, Gerhard (Springer, 2014)

Path integral (PI) control defines a general class of control problems for which the optimal control computation is equivalent to an inference problem that can be solved by evaluation of a path integral over state trajectories. ...
The Variational Garrote

Kappen, Hilbert J.; Gómez, Vicenç (Springer, 2014)

We analyze the variational method for sparse regression using ℓ 0 regularization. The variational approximation results in a model that is similar to Breiman’s Garrote model. We refer to this method as the Variational ...
