  • 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 ...
  • 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 ...
  • Lykousas, Nikolaos; Gómez, Vicenç; Patsakis, Constantinos (Institute of Electrical and Electronics Engineers, 2018)
    Social Live Stream Services (SLSS) exploit a new level of social interaction. One of the main challenges in these services is how to detect and prevent deviant behaviors that violate community guidelines. In this work, we ...
