Query: GPU-Accelerated Policy Optimization via Batch Automatic Differentiation
  of Gaussian Processes for Real-World Control   The ability of Gaussian processes (GPs) to predict the behavior of dynamical
systems as a more sample-efficient alternative to parametric models seems
promising for real-world robotics research. However, the computational
complexity of GPs has made policy search a highly time and memory consuming
process that has not been able to scale to larger problems. In this work, we
develop a policy optimization method by leveraging fast predictive sampling
methods to process batches of trajectories in every forward pass, and compute
gradient updates over policy parameters by automatic differentiation of Monte
Carlo evaluations, all on GPU. We demonstrate the effectiveness of our approach
in training policies on a set of reference-tracking control experiments with a
heavy-duty machine. Benchmark results show a significant speedup over exact
methods and showcase the scalability of our method to larger policy networks,
longer horizons, and up to thousands of trajectories with a sublinear drop in
speed.
