Bayesian reinforcement learning (BRL) offers a decision-theoretic solution for reinforcement learning. Here, we introduce Fig. , 2006 Abstract Reinforcement learning (RL) was originally proposed as a framework to allow agents to learn in an online fashion as they interact with their environment. Reinforcement Learning (RL) based on the framework of Markov Decision Processes (MDPs) is an attractive paradigm for learning by interacting with a stochas-tic environment and receiving rewards and penalties. Bayesian reinforcement learning (RL) is a technique devised to make better use of the information observed through learning than simply computing Q-functions. The key aspect of the proposed method is the design of the Bayesian Reinforcement Learning Bayesian RL lever-ages methods from Bayesian inference to incorporate prior information about the Markov model into the learn-ing process. Reinforcement learning is a rapidly growing area of in-terest in AI and control theory.

We put forward the Reinforcement Learning/Guessing (RLGuess) model — enabling researchers to model this learning and guessing process. The method exploits approximate knowledge of the system dynamics to guarantee constraint satisfaction while minimally interfering with the learning process. For example, many Bayesian models are agnostic of inter-individual variability and involve complicated integrals, making online learning difficult.
