Preference-Based Reinforcement Learning: A Preliminary Survey
Christian Wirth, Johannes Fürnkranz · 2013
Abstract. Preference-based reinforcement learning has gained significant popularity over the years, but it is still unclear what exactly preference learning is and how it relates to other reinforcement learning tasks. In this paper, we present a general definition of preferences as well as some insight how these approaches compare to reinforcement learning, inverse reinforcement learning and other related approaches. Additionally, we are offering a coarse categorization of preference-based reinforcement learning algorithms and a preliminary survey based on this allocation. 1
