Query: Safety-Guided Deep Reinforcement Learning via Online Gaussian Process
  Estimation   An important facet of reinforcement learning (RL) has to do with how the
agent goes about exploring the environment. Traditional exploration strategies
typically focus on efficiency and ignore safety. However, for practical
applications, ensuring safety of the agent during exploration is crucial since
performing an unsafe action or reaching an unsafe state could result in
irreversible damage to the agent. The main challenge of safe exploration is
that characterizing the unsafe states and actions is difficult for large
continuous state or action spaces and unknown environments. In this paper, we
propose a novel approach to incorporate estimations of safety to guide
exploration and policy search in deep reinforcement learning. By using a cost
function to capture trajectory-based safety, our key idea is to formulate the
state-action value function of this safety cost as a candidate Lyapunov
function and extend control-theoretic results to approximate its derivative
using online Gaussian Process (GP) estimation. We show how to use these
statistical models to guide the agent in unknown environments to obtain
high-performance control policies with provable stability certificates.
