signal processing. In particular, the chapter will cover a general
introduction to machine learning and how it is used in classifica-
tion, regression and density estimation. Following this introduction,
two particularly well-known models will be presented, together with
their associated learning algorithm: support vector machines (SVM),
which are well known for classification tasks; and hidden Markov
models (HMM), which are tailored for sequence processing tasks
such as speech recognition.
2.2 INTRODUCTION TO STATISTICAL LEARNING
We introduce here briefly the formalism of statistical
