Center node: "control tutored reinforcement learning an application to the herding problem"
  Abstract: In this extended abstract we introduce a novel {\em control-tutored} Q-learning approach (CTQL) as part of the ongoing effort in developing model-based and safe RL for continuous state spaces. We validate our approach by applying it to a challenging multi-agent herding control problem.

Connected through hyperedge HE-1 (induced by source paper "driving reinforcement learning with models"):

    - "lifelong federated reinforcement learning a learning architecture for navigation in cloud robotic systems"
    - "model ensemble trust region policy optimization"
    - "data driven policy transfer with imprecise perception simulation"
    - "chauffeurnet learning to drive by imitating the best and synthesizing the worst"
    - "learn fast forget slow safe predictive learning control for systems with unknown and changing dynamics performing repetitive tasks"
