Reinforcement Learning: A Survey
TLDR
A survey of reinforcement learning from a computer science perspective can be found in this article, where the authors discuss the central issues of RL, including trading off exploration and exploitation, establishing the foundations of RL via Markov decision theory, learning from delayed reinforcement, constructing empirical models to accelerate learning, making use of generalization and hierarchy, and coping with hidden state.Abstract:
This paper surveys the field of reinforcement learning from a computer-science perspective. It is written to be accessible to researchers familiar with machine learning. Both the historical basis of the field and a broad selection of current work are summarized. Reinforcement learning is the problem faced by an agent that learns behavior through trial-and-error interactions with a dynamic environment. The work described here has a resemblance to work in psychology, but differs considerably in the details and in the use of the word ``reinforcement.'' The paper discusses central issues of reinforcement learning, including trading off exploration and exploitation, establishing the foundations of the field via Markov decision theory, learning from delayed reinforcement, constructing empirical models to accelerate learning, making use of generalization and hierarchy, and coping with hidden state. It concludes with a survey of some implemented systems and an assessment of the practical utility of current methods for reinforcement learning.read more

Multi-resolution Exploration in Continuous Spaces
Ali Nouri,Michael L. Littman +1 more
TL;DR: This work proposes a new methodology for representing uncertainty in continuous-state control problems by using a hierarchical mapping to identify regions of the state space that would benefit from additional samples and demonstrates MRE's broad utility by using it to speed up learning in a prototypical model-based and value-based reinforcement-learning method.

Heuristic selection of actions in multiagent reinforcement learning
TL;DR: A set of empirical evaluations were conducted for the proposed algorithm in a simplified simulator for the robot soccer domain, and experimental results show that even very simple heuristics enhances significantly the performance of the multiagent reinforcement learning algorithm.

A Hybrid Privacy Protection Scheme in Cyber-Physical Social Networks
TL;DR: This work proposes a hybrid privacy-preserving scheme, which considers both location and identity privacy against a dynamic adversary, and establishes a game-based Markov decision process model, in which the user and the adversary are regarded as two players in a dynamic multistage zero-sum game.

A framework for meta-level control in multi-agent systems
Anita Raja,Victor Lesser +1 more
TL;DR: It is shown that meta-level control with bounded computational overhead allows complex agents to solve problems more efficiently than current approaches in dynamic open multi-agent environments.
