  Growing concerns regarding the operational usage of AI models in the
real-world has caused a surge of interest in explaining AI models' decisions to
humans. Reinforcement Learning is not an exception in this regard. In this
work, we propose a method for offering local explanations on risk in
reinforcement learning. Our method only requires a log of previous interactions
between the agent and the environment to create a state-transition model. It is
designed to work on RL environments with either continuous or discrete state
and action spaces. After creating the model, actions of any agent can be
explained in terms of the features most influential in increasing or decreasing
risk or any other desirable objective function in the locality of the agent.
Through experiments, we demonstrate the effectiveness of the proposed method in
providing such explanations.
