Researchers from various disciplines such as pattern recognition, statistics, and machine learning have explored the use of ensemble methodology since the late seventies. Thus, they are faced with a wide variety of methods, given the growing interest in the field. This book aims to impose a degree of order upon this diversity by presenting a coherent and unified repository of ensemble methods, theories, trends, challenges and applications. The book describes in detail the classical methods, as well as the extensions and novel approaches developed recently. Along with algorithmic descriptions of each method, it also explains the circumstances in which this method is applicable and the consequences and the trade-offs incurred by using the method.

Ensembles In Machine Learning Applications

This book contains the extended papers presented at the 3rd Workshop on Supervised and Unsupervised Ensemble Methods and their Applications (SUEMA) that was held in conjunction with the European Conference on Machine Learning and Principles and Practice of Knowledge Discovery in Databases (ECML/PKDD 2010, Barcelona, Catalonia, Spain). As its two predecessors, its main theme was ensembles of supervised and unsupervised algorithms – advanced machine learning and data mining technique. Unlike a single classification or clustering algorithm, an ensemble is a group of algorithms, each of which first independently solves the task at hand by assigning a class or cluster label (voting) to instances in a dataset and after that all votes are combined together to produce the final class or cluster membership. As a result, ensembles often outperform best single algorithms in many real-world problems. This book consists of 14 chapters, each of which can be read independently of the others. In addition to two previous SUEMA editions, also published by Springer, many chapters in the current book include pseudo code and/or programming code of the algorithms described in them. This was done in order to facilitate ensemble adoption in practice and to help to both researchers and engineers developing ensemble applications.

The 13th Iberoamerican Congress on Pattern Recognition (CIARP 2008, C- greso IberoAmericano de Reconocimiento de Patrones) was the 13th event in a seriesofpioneercongressesonpatternrecognitioninthecommunityofIberoam- icancountries. As was the case for previous conferences, CIARP 2008 attracted participants from around the world with the aim of promoting and disseminating ongoing researchon mathematical methods and computing techniques for pattern rec- nition, computer vision, image analysis, and speech recognition, as well as their application in such diverse areas as robotics, industry, health, entertainment, space exploration, telecommunications, data mining, document analysis, and natural language processing and recognition to name only few of them. Mo- over, it provided a forum for scienti?c research, experience exchange, share of new knowledge and an increase in cooperation between research groups in p- tern recognition and related areas. It is important to underline the fact that these conferences have contributed signi?cantly to the growth of national associations for pattern recognitionin the Iberoamerican region, all of them as members of the International Association for Pattern Recognition (IAPR). This year, the forum attracted participants from 34 countries (8 from Iberoamerica), who submitted a total of 182 papers. After a serious reviewing process in which allthe submissions where double-blind reviewedby at least two prestigiousreviewers,93 papersby180authors from29 countries wereaccepted, all of them with a scienti?c quality above overall mean rating.

An up-to-date, self-contained introduction to a state-of-the-art machine learning approach, Ensemble Methods: Foundations and Algorithms shows how these accurate methods are used in real-world tasks. It gives you the necessary groundwork to carry out further research in this evolving field. After presenting background and terminology, the book covers the main algorithms and theories, including Boosting, Bagging, Random Forest, averaging and voting schemes, the Stacking method, mixture of experts, and diversity measures. It also discusses multiclass extension, noise tolerance, error-ambiguity and bias-variance decompositions, and recent progress in information theoretic diversity. Moving on to more advanced topics, the author explains how to achieve better performance through ensemble pruning and how to generate better clustering results by combining multiple clusterings. In addition, he describes developments of ensemble methods in semi-supervised learning, active learning, cost-sensitive learning, class-imbalance learning, and comprehensibility enhancement.
