Abstract
Machine Learning algorithms are becoming more prevalent in critical systems where dynamic decision making and efficiency are the goal. As is the case for complex and safety-critical systems, where certain failures can lead to harm, we must proactively consider the safety assurance of such systems that use Machine Learning. In this paper we explore the implications of the use of Reinforcement Learning in particular, considering the potential benefits that it could bring to safety-critical systems, and our ability to provide assurances on the safety of systems incorporating such technology. We propose a high-level argument that could be used as the basis of a safety case for Reinforcement Learning systems, where the selection of ‘reward’ and ‘cost’ mechanisms would have a critical effect on the outcome of decisions made. We conclude with fundamental challenges that will need to be addressed to give the confidence necessary for deploying Reinforcement Learning within safety-critical applications.
