    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 ...
  • 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 ...
  • 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 ...
  • 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 ...
