The significantly expanded and updated new edition of a widely used text on reinforcement learning, one of the most active research areas in artificial intelligence. Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives while interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the field's key ideas and algorithms. This second edition has been significantly expanded and updated, presenting new topics and updating coverage of other topics. Like the first edition, this second edition focuses on core online learning algorithms, with the more mathematical material set off in shaded boxes. Part I covers as much of reinforcement learning as possible without going beyond the tabular case for which exact solutions can be found. Many algorithms presented in this part are new to the second edition, including UCB, Expected Sarsa, and Double Learning. Part II extends these ideas to function approximation, with new sections on such topics as artificial neural networks and the Fourier basis, and offers expanded treatment of off-policy learning and policy-gradient methods. Part III has new chapters on reinforcement learning's relationships to psychology and neuroscience, as well as an updated case-studies chapter including AlphaGo and AlphaGo Zero, Atari game playing, and IBM Watson's wagering strategy. The final chapter discusses the future societal impacts of reinforcement learning.

This e-book offers an insightful look into the way today's students think about and use technology in their academic and social lives. It will help institutional leaders help their students to become more successful and satisfied.

Quiet, sensitive Faith starts middle school already worrying about how she will fit in. To her surprise, Amanda, a popular eighth grader, convinces her to join the school soccer team, the Bloodhounds. Having never played soccer in her life, Faith ends up on the C team, a ragtag group that’s way better at drama than at teamwork. Although they are awful at soccer, Faith and her teammates soon form a bond both on and off the soccer field that challenges their notions of loyalty, identity, friendship, and unity. The Breakaways from Cathy G. Johnson is a raw, and beautifully honest graphic novel that looks into the lives of a diverse and defiantly independent group of kids learning to make room for themselves in the world.

*This book is in the Rapid Communications in Conflict and Security (RCCS) Series (General Editor: Geoffrey R.H. Burn). The Office of Net Assessment (ONA) was responsible for carrying out three programs in the Department of Defense from November 1973 until the collapse of the Soviet Union. Net assessments utilize a multidisciplinary approach to defense analysis to capture the dynamics of national or coalition military strengths and weaknesses for comparison with the capabilities of competitors and adversaries. In this book, essays by experts including a number of individuals who have served in or worked for the ONA in the past, such as Andrew Marshall (Director of the United States Department of Defense's Office of Net Assessment, 1973-2015) and Andrew May (Associate Director of the United States Department of Defense's Office of Net Assessment) offer critical insights on the relative military power of the United States vis-à-vis potential adversaries over time. This book is an invaluable resource for scholars and students in international relations, political science, and conflict and security.
