  abstract = "Reinforcement Learning (RL) is a paradigm for
learning decision-making tasks that could enable robots to learn
and adapt to their situation on-line. For an RL algorithm to
be practical for robotic control tasks, it must learn in very few
samples, while continually taking actions in real-time. Existing
model-based RL methods learn in relatively few samples, but
typically take too much time between each action for practical
on-line learning. In this paper, we present a novel parallel
architecture for model-based RL that runs in real-time by
1) taking advantage of sample-based approximate planning
methods and 2) parallelizing the acting, model learning, and
planning processes in a novel way such that the acting process is
sufficiently fast for typical robot control cycles. We demonstrate
that algorithms using this architecture perform nearly as well as
methods using the typical sequential architecture when both are
given unlimited time, and greatly out-perform these methods
on tasks that require real-time actions such as controlling an
autonomous vehicle.",
