In supervised learning or learning-fromexamples a machine is trained, instead of programmed, to perform a given task on a number of input-output pairs.

According to this paradigm, training means choosing a function which best describes the relation between the inputs and the outputs. The central question of SLT is how well the the chosen function generalizes, or how well it estimates the output for previously unseen inputs.
The choice of the loss function determines dierent learning techniques, each leading to a dierent learning algorithm for computing the coecients ci. The rest of the paper is organized as follows. Section 2 presents the main idea and concepts in the theory.
Section 3 discusses Regularization Networks and Support Vector Machines, two important techniques which produce outputs of the form of equation 1.
The relationship is probabilistic because generally an element of X does not?? This can be formalized assuming that an unknown probability distribution P x, y is dened over the set X Y. The problem of learning consists in, given the data set D , providing an estimator, that is a function f : X Y , that can be used, given any value of x X , to predict a value y.
Another example is the case where x is a set of parameters, such as pose or facial expressions, y is a motion eld relative to a particular reference image of a face, and f x is a regression function which maps parameters to motion see for example .
The Nature of Statistical Learning Theory
In SLT, the standard way to solve the learning problem consists in dening a risk functional, which measures the average amount of error or risk associated with an estimator, and then looking for the estimator with the lowest risk. Advertisement Hide.

Explaining these areas at a level and in a way that is not often found in other books on the topic, the authors present the basic theory behind contemporary machine learning and uniquely utilize its foundations as a framework for philosophical thinking about inductive inference.
Promoting the fundamental goal of statistical learning, knowing what is achievable and what is not, this book demonstrates the value of a systematic methodology when used along with the needed techniques for evaluating the performance of a learning system. First, an introduction to machine learning is presented that includes brief discussions of applications such as image recognition, speech recognition, medical diagnostics, and statistical arbitrage.
To enhance accessibility, two chapters on relevant aspects of probability theory are provided.
Subsequent chapters feature coverage of topics such as the pattern recognition problem, optimal Bayes decision rule, the nearest neighbor rule, kernel rules, neural networks, support vector machines, and boosting.
Appendices throughout the book explore the relationship between the discussed material and related topics from mathematics, philosophy, psychology, and statistics, drawing insightful connections between problems in these areas and statistical learning theory. All chapters conclude with a summary section, a set of practice questions, and a reference sections that supplies historical notes and additional resources for further study. It also serves as an introductory reference for researchers and practitioners in the fields of engineering, computer science, philosophy, and cognitive science that would like to further their knowledge of the topic.
