I am Associate Professor at the Interactive Intelligence group at TU Delft.
My main research interests lie in what I call interactive learning and decision making: the intersection of AI, machine learning and game theory. I try to generate fundamental knowledge about algorithms and models for complex tasks. In addition, I think about how such abstract models might be applied to challenging real-world tasks such as collaboration in multi-robot systems, optimization of traffic control systems, intelligent e-commerce agents, etc.

November 5th, 2020: NeurIPS camready: MDP Homomorphic Networks
In this work we show how symmetries that can occur in MDPs can be exploited for more efficient deep reinforcement learning.

November 5th, 2020: NeurIPS Camready: Multi-agent active perception with prediction rewards
This paper shows that also in decentralized multiagent settings we can employ “prediction rewards” for active perception. (Intuitively leading to a type of voting that we try to optimize).

November 5th, 2020: NeurIPS Camready: Influence-Augmented Online Planning
The camready version of Influence-Augmented Online Planning for Complex Environments is now available.
In this work, we show that by learning approximate representations of influence, we can speed up online planning (POMCP) sufficiently to get better performance when the time for online decision making is constrained.

April 24th, 2020: AAMAS: Maximizing Information Gain via Prediction Rewards
This paper tackles the problem of active perception: taking actions to minimize one’s uncertainty. It further formalizes the link between information gain and prediction rewards, and uses this to propose a deep-learning approach to optimize active perception from a data set, thus obviating the need for a complex POMDP model.
