Abstract

Traduction adaptée d'un manuel américain de référence en comptabilité de gestion ; sa démarche pédagogique est typique des manuels universitaires américains. Cet ouvrage présente les notions traditionnelles de contrôle des coûts en expliquant la façon dont les managers utilisent les informations dans le monde réel de l'entreprise. Le manuel aide les étudiants à devenir non seulement de bons praticiens du contrôle des coûts mais aussi des managers efficaces. Des exercices innovants " Vous êtes le décideur " dans le corps des chapitres apprennent aux étudiants à poser les bonnes questions au sujet des coûts, et encore plus important, à prendre les bonnes décisions. Chacun des 20 chapitres est construit autour d'une entreprise fictive dont l'histoire se poursuit tout au long du chapitre. Un très grand nombre d'exercices et de problèmes comportent des questions dont la résolution implique l'usage d'Excel. Cet outil d'analyse étant le plus répandu dans le monde de l'entreprise, les employeurs cherchent des employés maîtrisant ce logiciel. Le manuel présente ainsi données et calculs dans le format d'Excel afin que les étudiants se familiarisent avec les outils utilisés dans l'entreprise. La démarche pédagogique adoptée par les auteurs vise à montrer que les coûts ne sont pas une fatalité. Une attitude dynamique envers ceux-ci permet aux étudiants de rendre de précieux services aux entreprises qui les auront recrutés. Cet ouvrage intéressera les étudiants de niveaux universitaires L et M, les étudiants en école de commerce ainsi que tous les enseignants désireux d'actualiser leurs connaissances.

Abstract

"Using the tools of complexity theory, Stephen Judd develops a formal description of associative learning in connectionist networks. He rigorously exposes the computational difficulties in training neural networks and explores how certain design principles will or will not make the problems easier. Judd looks beyond the scope of any one particular learning rule, at a level above the details of neurons. There he finds new issues that arise when great numbers of neurons are employed and he offers fresh insights into design principles that could guide the construction of artificial and biological neural networks. The first part of the book describes the motivations and goals of the study and relates them to current scientific theory. It provides an overview of the major ideas, formulates the general learning problem with an eye to the computational complexity of the task, reviews current theory on learning, relates the book's model of learning to other models outside the connectionist paradigm, and sets out to examine scale-up issues in connectionist learning. Later chapters prove the intractability of the general case of memorizing in networks, elaborate on implications of this intractability and point out several corollaries applying to various special subcases. Judd refines the distinctive characteristics of the difficulties with families of shallow networks, addresses concerns about the ability of neural networks to generalize, and summarizes the results, implications, and possible extensions of the work. J. Stephen Judd is Visiting Assistant Professor of Computer Science at The California Institute of Technology. Neural Network Design and the Complexity of Learning is included in the Network Modeling and Connectionism series edited by Jeffrey Elman."

Abstract

This is the only book actuaries need to understand generalized linear models (GLMs) for insurance applications. GLMs are used in the insurance industry to support critical decisions. Until now, no text has introduced GLMs in this context or addressed the problems specific to insurance data. Using insurance data sets, this practical, rigorous book treats GLMs, covers all standard exponential family distributions, extends the methodology to correlated data structures, and discusses recent developments which go beyond the GLM. The issues in the book are specific to insurance data, such as model selection in the presence of large data sets and the handling of varying exposure times. Exercises and data-based practicals help readers to consolidate their skills, with solutions and data sets given on the companion website. Although the book is package-independent, SAS code and output examples feature in an appendix and on the website. In addition, R code and output for all the examples are provided on the website.
