<p>
In this paper, we present a computationally efficient
algorithm for solving a class of chance constrained optimization
under non-parametric uncertainty. Our algorithm is built on the
possibility of representing arbitrary distributions as functions
in Reproducing Kernel Hilbert Space (RKHS). We use this
foundation to formulate chance constrained optimization as one
of minimizing the distance between a desired distribution and the
distribution of the constraint functions in the RKHS. We provide
a systematic way of constructing the desired distribution based
on the notion of scenario approximation. Furthermore, we use the
kernel trick to show that the computational complexity of our
reformulated optimization problem is comparable to solving a
deterministic variant of the chance constrained optimization. We
validate our formulation on two important robotic applications:
(i) reactive collision avoidance of mobile robots in uncertain
dynamic environments and (ii) inverse dynamics based path
tracking of manipulators under perception uncertainty. In both
these applications, the underlying chance constraints are defined
over non-linear and non-convex functions of the uncertain pa-
rameters and possibly also decision variables. We also benchmark
our formulation with the existing approaches in terms of sample
complexity and the achieved optimal cost highlighting significant
improvements in both these metrics.
