An easy-to-follow introduction to support vector machines

This book provides an in-depth, easy-to-follow introduction to support vector machines drawing only from minimal, carefully motivated technical and mathematical background material. It begins with a cohesive discussion of machine learning and goes on to cover:

Knowledge discovery environments

Describing data mathematically

Linear decision surfaces and functions

Perceptron learning

Maximum margin classifiers

Support vector machines

Elements of statistical learning theory

Multi-class classification

Regression with support vector machines

Novelty detection

Complemented with hands-on exercises, algorithm descriptions, and data sets, "Knowledge Discovery with Support Vector Machines" is an invaluable textbook for advanced undergraduate and graduate courses. It is also an excellent tutorial on support vector machines for professionals who are pursuing research in machine learning and related areas.
