Abstract: Agent systems based on deep reinforcement learning have achieved remarkable success in recent years. They have also been applied to a variety of research topics in the field of power grids, as such agents promise real resilience. However, deep reinforcement learning agents cannot guarantee behavior, as the mapping of the entire input space to the output of even a simple feed-forward neural network cannot be accurately explained. For critical infrastructures, such black box models are not acceptable. To ensure an optimized trade-off between learning performance and explainability, this paper relies on efficient regularizable feed-forward neural networks and presents an extension of the algorithm NN2EQCDT to transform the networks into pruned decision trees with significantly fewer nodes to be accurately explained. In this paper, we present a methodological approach to further analyze the decision trees for high-dimensional input-output spaces and analyze an agent for a power grid expe riment. (More)
