Learning Classifier Systems (LCS) are a machine learning paradigm introduced by John Holland in 1976. They are rule-based systems in which learning is viewed as a process of ongoing adaptation to a partially unknown environment through genetic algorithms and temporal difference learning. This book provides a unique survey of the current state of the art of LCS and highlights some of the most promising research directions. The first part presents various views of leading people on what learning classifier systems are. The second part is devoted to advanced topics of current interest, including alternative representations, methods for evaluating rule utility, and extensions to existing classifier system models. The final part is dedicated to promising applications in areas like data mining, medical data analysis, economic trading agents, aircraft maneuvering, and autonomous robotics. An appendix comprising 467 entries provides a comprehensive LCS bibliography.
The field called Learning Classifier Systems is populated with romantics. Why shouldn't it be possible for computer programs to adapt, learn, and develop while interacting with their environments? In particular, why not systems that, like organic populations, contain competing, perhaps cooperating, entities evolving together? John Holland was one of the earliest scientists with this vision, at a time when so-called artificial intelligence was in its infancy and mainly concerned with preprogrammed systems that didn't learn. that, like organisms, had sensors, took Instead, Holland envisaged systems actions, and had rich self-generated internal structure and processing. In so doing he foresaw a...
Learning classi er systems are rule-based systems that exploit evolutionary c- putation and reinforcement learning to solve di cult problems. They were - troduced in 1978 by John H. Holland, the father of genetic algorithms, and since then they have been applied to domains as diverse as autonomous robotics, trading agents, and data mining. At the Second International Workshop on Learning Classi er Systems (IWLCS 99), held July 13, 1999, in Orlando, Florida, active researchers reported on the then current state of learning classi er system research and highlighted some of the most promising research directions. The most interesting contri- tions to the meeting are included in the book Learning Classi er Systems: From Foundations to Applications, published as LNAI 1813 by Springer-Verlag. The following year, the Third International Workshop on Learning Classi er Systems (IWLCS 2000), held September 15{16 in Paris, gave participants the opportunity to discuss further advances in learning classi er systems. We have included in this volume revised and extended versions of thirteen of the papers presented at the workshop.
The volume contains a selection of manuscripts of lectures presented at the International Symposi um on Operations Research (SOR 96). The Symposium took place at the Technical University of Braunschweig, September 3-6, 1996. SOR 96 was organized under the auspices of the two German societies of Operations Research, Deutsche Gesellschaft fur Operations Research (DGOR) and Gesellschaft fur Mathematik, Okonomie and Operations Research (GMOOR) in cooperation with the Working Group Discrete Optimization of the IFIP (WG7.4). Since 1995, DGOR and GMOORjointly prepare the Symposium as a common annual conference. In particular, the annual general meetings of the DGOR, the GMOOR and the WG7.4 took pla...
The international debt problem has already generated a huge number of publications. Why then another publication? Many publications address macroeconomic implications of the debt problem, others investigate special new financing instruments such as debt equity swaps, others discuss the economic or legal aspects of debt reschedulings. This work of Walter Berger concentrates on the evolution of the financial side of the debt problem. This evolution is fascinating since it reveals a continuous expansion of the financial instruments being used and a surprising change in intercreditor relationships. While in the seventies equal treatment of creditors was not of much concern, this changed dramatic...
Trotz Börsenflaute ist Electronic Business ein Thema, das die wirtschaftliche Realität verändert hat und in Zukunft weiter verändern wird. In diesem Buch wird das Thema zunächst aus Sicht der betrieblichen Funktionsbereiche wie Einkauf, Produktion und Vertrieb behandelt. Anschließend erfolgt eine Betrachtung aus der Sicht der Querschnittsfunktionen der Unternehmungen wie z.B. Personal, Organisation, Rechnungswesen und Controlling. Auch das E-Business in öffentlichen Betrieben wird mit zwei Beiträgen vorgestellt. Ein letzter Beitrag beschäftigt sich mit den Aktivitäten im Bereich E-Business bzw. E-Commerce in Forschung und Lehre an einer Hochschule, wobei vor allem die Kooperationen mit Praxispartnern im Vordergrund stehen. Autoren des Buches sind Hochschullehrer und Praktiker.
Inhaltsangabe:Abstract: The beginning of the 21st century with the fear of the "Year 2000"-threat (Y2K) became a milestone for the "Information Age", a term coined for the post-industrial stage of leading countries [ ] when information and information technologies become the main strategic national resource which results in an avalanche growth of information dependence in all spheres of society and state activities. . In organisations the awareness of the dependence on information has led to corporate initiatives to treat information as an asset, which includes various efforts for its protection. Management trends such as "knowledge management" have identified "knowledge sharing" as a new me...
Patrick Dahmen analyses the internal and external dimensions of multi-channel strategies and develops a management framework for their strategic design and operational implementation. Case studies illustrate the underlying managerial challenges.
Methoden der Programm-Entwicklung kennt man seitdem es Computer gibt. Auf grund der Veränderung der Leistungen, die auf dem Computer bewältigt werden können, verschieben sich ebenfalls seit dieser Zeit die Ziele der Programmierung. Während es in der Anfangsphase mehr darauf ankam, möglichst viele Maschinen befehle auf dem verfügbaren kleinen Speicherplatz darzustellen, ging es in den 50er und 60er Jahren primär darum, möglichst schnelle und effektive Programme zu entwickeln, wobei der Schwerpunkt sowohl auf der Geschwindigkeit als auch auf der Speicherknappheit lag. Heute dürften die wesentlichen Ziele darin beste hen, Programme so zu entwickeln, daß sie möglichst computerunabhän...
