In reinforcement learning (RL) problems, learning agents sequentially execute actions with the goal of maximizing a reward signal. The RL framework has gained popularity with the development of algorithms capable of mastering increasingly complex problems, but learning difficult tasks is often slow or infeasible when RL agents begin with no prior knowledge. The key insight behind "transfer learning" is that generalization may occur not only within tasks, but also across tasks. While transfer has been studied in the psychological literature for many years, the RL community has only recently begun to investigate the benefits of transferring knowledge. This book provides an introduction to the RL transfer problem and discusses methods which demonstrate the promise of this exciting area of research. The key contributions of this book are: Definition of the transfer problem in RL domains Background on RL, sufficient to allow a wide audience to understand discussed transfer concepts Taxonomy for transfer methods in RL Survey of existing approaches In-depth presentation of selected transfer methods Discussion of key open questions By way of the research presented in this book, the author has established himself as the pre-eminent worldwide expert on transfer learning in sequential decision making tasks. A particular strength of the research is its very thorough and methodical empirical evaluation, which Matthew presents, motivates, and analyzes clearly in prose throughout the book. Whether this is your initial introduction to the concept of transfer learning, or whether you are a practitioner in the field looking for nuanced details, I trust that you will find this book to be an enjoyable and enlightening read.

The story of British football's journey from public school diversion to mass media entertainment is a remarkable one. The Association Game traces British football from the establishment of the earliest clubs in the nineteenth century to its place as one of the prominent and commercialised leisure industries at the beginning of the twenty first century. It covers supporters and fandom, status and culture, big business, the press and electronic media and development in playing styles, tactics and rules. This is the only up to date book on the history of British football, covering the twentieth century shift from amateur to professional and whole of the British Isles, not just England.

As a universal game, association football has been particularly suited to the transfer of labour forces. It does not require the use of a specific national language, a recognized diploma or acquired qualification, and the rules are standardized across the globe. Thus the international football market could be considered an ideal example of a transnational and multicultural employment sector. Role models throughout the history of professional football have not necessarily come from the town, nation, racial group or religious denomination of the majority of supporters, as is seen in the cases of Maradona in Naples, the German Bert Trautmann after the Second World War, and more recently the Frenchman Eric Cantona in Manchester, the Cameroonese Milla in France, and the Argentinian Di Stefano in Madrid. Football provides a particularly revealing lens through which to examine changes in national styles and stereotypes as they have been (and still are) reflected in the search for identities in sporting heroes. In this book, the authors consider the movement of football labour from the late nineteenth-century to the present day within the framework of international migration as a whole. Emphasis is given to the initial role of the British in the early twentieth century and the impact of the earliest South American and Yugoslav football 'wanderers'. The position of African footballers in the postwar period and the failure of America's national league in the 1970s are also discussed, along with the international market for coaches and managers, the development of national playing styles and the immediate consequences and future implications of the Bosman ruling.

This book examines the pros and cons of the local production of carpentry hand-tools as opposed to their importation. In seeking the best strategy to adopt it also outlines the previous methods adopted by VSO and Intermediate Technology who have much experience in this area.
