Conoscenze e abilità da conseguire

At the end of this course the student will learn the principles and commonly used paradigms and techniques of pattern recognition. In particular he/she will be able to: - explain and compare a variety of pattern classification techniques, - apply performance evaluation methods for pattern recognition, - apply pattern recognition techniques to real-world problems in the Applied Physics field, - implement simple pattern classifiers, - demonstrate successful applications to process and analyze data (e.g. images), and make automatic decisions based on extracted feature information.
