Prerequisites:

The student should be familiar with basic concepts in Probability and Analysis of multivariate functions. It is also advisable to have basic knowledge of Programming and Artificial Intelligence.
The course does not have prerequisites. 
Target skills and knowledge:

The aim of the course is to introduce the student to the basic concepts that characterize Machine Learning, i.e. the class of techniques and algorithms that starting from empirical data allow a computer system to acquire new knowledge, or to correct and/or to refine knowledge already available. These techniques are particularly useful for problems for which it is impossible or very difficult to reach a mathematical formalization usable for the definition of an ad hoc algorithmic solution. Examples of these problems are perceptual tasks, such as visual recognition of handwritten digits, or problems in which data is corrupted by noise or is incomplete. The course mainly covers numerical methods.
Students will face practical exercises in a computer lab that allow them to test the application of the acquired knowledge to small practical examples. 
Examination methods:

The student must pass a written examination and, if deemed necessary by the teacher, an oral examination. 
Assessment criteria:

The text of the written exam includes some questions that aim to assess the level of learning reached by the student concerning the concepts taught in the course and the student's ability to perform a critical analysis on them. The text also includes questions in which the student is required to show understanding of the applicative issues taught in the computer lab. These questions are designed to assess whether the student has developed the ability to apply the concepts learned during the course.
In the event that the assessment of the written exam is not satisfactory for the student, the teacher may supplement the written examination with an oral examination to better assess the level of learning of the student. 
Course unit contents:

The course will cover the topics listed below
 Introduction:
When to apply Machine Learning techniques; Machine Learning Paradigms; Basic ingredients of Machine Learning.
 Learning Concepts:
The complexity of the Hypothesis Space; Complexity Measures; Examples of Supervised Learning Algorithms;
 Decision Trees:
Learning Decision Trees; Treatment of Numerical Data, Missing Data, Costs; Pruning Techniques and Derivation of Decision Rules.
 Probabilistic Learning:
Bayesian Learning; Examples of Application to Supervised and Unsupervised Learning (clustering); Optimal Bayes classifier; EM.
 Neural Networks and Support Vector Machines:
Introduction to Neural Networks; Classification Margin, Support Vector Machines for Classification and Regression, Kernel Functions.
 Application Issues:
Classification Pipeline, Representation, and Selection of Categorical Variables; Model Selection, Holdout, CrossValidation, LeaveOneOut CV; Exterior and Interior Criteria for Evaluating a Clustering System; Recommendation Systems: Types, Approaches, Evaluation Measures. 
Planned learning activities and teaching methods:

The course consists of lectures and exercises in the computer lab. The exercises in the computer lab allow the students to experiment, under various operating scenarios, with the techniques introduced in class. In this way, students can verify experimentally the concepts learned in class and acquire the ability to apply the learned concepts and to perform critical judgment. 
Additional notes about suggested reading:

Slides presented during the lectures are made available to students as reference material.
