    7) Publication of the week - Autonomous Drifting using Simulation-Aided Reinforcement Learning (2016).
    INFO: This paper by Mark Cutler and Jonathan P. How introduces a framework that combines simple and complex continuous state-action simulators with a real-world robot to efficiently find good control policies, while minimizing the number of samples needed from the physical robot. While many Reinforcement Learning Researchers use expert demonstration to initialize the models, the authors of this paper chose an approach in which they generate initial policies from simple models. On the car Researchers track velocities in x and y direction (the information is provided by a motion capture system), turn rate and wheel speed. By applying the algorithm shown in this paper combined with prior simulated information the R/C car was able to drift as it can be seen in this YouTube video. You can download additional material to the paper here.
