Previous Seminars & Events: 

Typically, meetings are on Fridays and start at 12:30 in the colloquium room (00.832) of the Department of Biophysics (Huygens Building, Radboud University), unless listed otherwise.

Schedule is due to changes—you might want to follow us on Twitter to be alerted when such a change occurs.

You may also be interested in the ICIS AI-group colloquia at the computer-science department, typically friday afternoon.

The first one considers KL-control in the online learning setting, where the state costs may change arbitrarily between consecutive rounds, and the learner only observes the costs at the end of each respective round. We show that a simple follow the leader algorithm achieves a regret of order log2(T) after T rounds, improving on the best known regret bound of order T^{3/4} for this setting. This work has been done with Gergely Neu [1]. The second one is about entropy-regularized average-reward reinforcement learning in general MDPs. We extend the linear-programming formulation of policy optimization in MDPs to accommodate convex regularization functions. We formalize a number of state-of-the-art reinforcement learning algorithms as approximate variants of Mirror Descent or Dual Averaging, and argue about the convergence properties of these methods. This work has been done with Gergely Neu and Anders Jonsson [2]. [1] Fast rates for online learning in Linearly Solvable Markov Decision Processes. G. Neu and V.
