5. 2 Model-based Reinforcement Learning as Bayesian Inference In this section, we describe MBRL as a Bayesian inference problem using control as inference framework . In the process, dozens of new algorithms have been proposed for solving these problems with deep neural networks, speciﬁc of course to domain at hand. 4 and conclude with what entails from this connection in Sec. ∙ 0 ∙ share . We provide background on variational inference and reinforcement learning in Secs. Research . Variational inference is a widely used approximate infer-ence method. Deep learning now plays an important role in many domains, for example, in generative modeling, deep reinforcement learning, and variational inference. 2 and 3.
Applying probabilistic models to reinforcement learning (RL) enables the uses of powerful optimisation tools such as variational inference in RL. Abstract: Reinforcement learning (RL) combines a control problem with statistical estimation: The system dynamics are not known to the agent, but can be learned through experience. Reinforcement Learning. The basic idea of reinforcement learning is that we want to train an model to make a sequence of predictions, where after each prediction, we recieve a reward, and enter into a new state. Applying probabilistic models to reinforcement learning (RL) has become an exciting direction of research owing to powerful optimisation tools such as variational inference … We then focus on the connection between the two frameworks in Sec. My interests span probabilisitic inference, stochastic processes, Bayesian inference, Bayesian nonparametrics, Bayesian reinforcement learning, approximate inference (variational and MCMC), statistical signal processing, and infromation theory. Varia-tional inference introduces an approximate distribution q Probability Functional Descent: A Unifying Perspective on GANs, Variational Inference, and Reinforcement Learning 2019 This paper provides a unifying view of a wide range of problems of interest in machine learning by framing them as the minimization of functionals defined on the space of probability measures. inference for a particular model class and derive the general case in the appendix. VIREL: A Variational Inference Framework for Reinforcement Learning Matthew Fellows, Anuj Mahajan, Tim G. J. Rudner, Shimon Whiteson fmatthew.fellows,anuj.mahajan,tim.rudner,email@example.com Abstract virel is a novel, theoretically grounded probabilistic inference framework for rein-forcement learning (RL) that utilises … 2 Variational Inference • We combine variational information optimisation and tools from deep learning to develop a scal- able algorithm for intrinsically-motivated reinforcement learning, demonstrating a new applica- tion of the variational theory for problems in reinforcement learning and decision making. (2. test- VIREL: A Variational Inference Framework for Reinforcement Learning. Moreover, there is a cool connection to modern variational inference that perhaps helps to make both of these things more clear. 11/03/2018 ∙ by Matthew Fellows, et al. Fig.2displays the graphical model for the formulation, with which an MBRL procedure can be re-written in a Bayesian fashion: (1. training-step) do inference of p( jD). A recent line of research casts ‘RL as inference’ and suggests a particular framework to generalize the RL problem as probabilistic inference. While there exists ﬁrst applications of varia-tional inference for discrete reinforcement learning (Furm-ston & Barber, 2010), it has never been used for pol-icy search in high dimensional parameter spaces.
