OVERVIEW

Machine learning is establishing as a very interesting scientific area thanks to the availability of more and more powerful computers and of algorithms allowing its application to the most diverse sectors, including key sectors for economic and societal development. This course presents the main machine learning methodologies aimed to “pattern recognition”, in particular for the classification of structurally represented data.

AIMS AND CONTENT

LEARNING OUTCOMES

In this course several Machine learning methods applied to pattern recognition are presented and their application to images from real domains is discussed: Decision Theory; Supervised Probability Density Estimation; Feature Reduction; Linear and Nonlinear Classification (MDM, k-nn, SVMs, classifier ensembles); Neural Networks and Deep Learning; Accuracy of Supervised Classification; Unsupervised Classification (Clustering); Fuzzy Sets and Clustering.

AIMS AND LEARNING OUTCOMES

Purpose of this course is to provide the fundamentals of machine learning and to present some advanced methods with special reference to the classification of structurally represented data; in addition, examples will be presented and applications will be discussed related to signal and image classification. Students will learn to represent the features (measures, attributes, characteristics) of a set of samples to be classified by  a multidimensional vector space; will be able to reduce the dimensionality of such a representation limiting the information loss, to estimate the probabilistic distributions of data, to classify samples with classical techniques and with more recent ones (SVMs, neural networks, deep learning, classifier ensembles), evaluate or estimate the accuracy of a supervised classifier, extract the natural classes (clusters) present in a data set, also representing the related uncertainty with the “fuzzy” approach and validating the related results.

PREREQUISITES

Calculus (functions of one or more variables, integrals, functional optimization); probability theory and random variables; matrix calculus.

TEACHING METHODS

Class lessons on theory, applications, and problem solutions. Lab exercises based on guided software implementation of some of the techniques learned at lesson.

The actual offer of lessons and lab exercises in presence will depend on the decisions of the Program Committee and of the University of Genoa in relation to the evolution of the sanitary emergency due to COVID-19.
