Obiettivi Formativi
Machine learning (ML) is a branch of Artificial Intelligence (AI) that was originally developed to enable computers to emulate human cognition and learn from training examples to predict future events. Today, ML techniques include a number of advanced statistical methods for regression and classification applied in a wide variety of fields (including medical diagnostics, credit card fraud detection, face and speech recognition and analysis of the stock market) where the main goal is to directly predict the dependent variable of interest, without focusing on the underlying relationships between the explanatory variables.
The statistical methods developed in the ML literature (also known as Statistical Learning methods) have been particularly successful in “Big Data” settings, where we have either information on a large number of units, or many pieces of information on each unit (or both).
The aim of this course is to present Machine Learning Techniques using an econometric perspective.
During this course, students will learn the various concepts and techniques intensively used in the Machine Learning literature such as random trees, random forests, boosting, neural networks and deep learning, with the complement of many practical examples.
By the end of this course students are expected to be able to master and implement most of these techniques on real data problems using the statistical software R, RStudio and Python.

Prerequisiti
Intermediate knowledge of econometrics, statistics and linear algebra.
Metodi didattici
Frontal Lectures in class coupled with practical examples and group “Hands-On” sessions with real data applications.
Verifica Apprendimento
The final assessment will be based for 50% on a take-home written report (15-20 pages) in which students will be asked to apply on real data examples (like a sort of kaggle-type competition) the techniques learned during the lectures. The other 50% of the final mark will based on an oral presentation (remotely via MS-Teams) of the take home/report with questions and answers on the topics covered during the lectures.
No partial exams will be held for this course.
No partial exams will be held for this course.
Contenuti

3. Linear Regression Models: Refresh, Extensions and Potential Problems. Practical examples of Linear Regression estimation (4 hours).
4. Classification: Linear Methods, Logistic Regression, Linear Discriminant Analysis. Comparison of Classification Methods (4 hours).
5. Model Validation and Selection: Cross-Validation and Bootstrap techniques. Shrinkage Methods: Ridge Regression and LASSO. (4 hours).
6. Dimension Reduction Methods: PCA and PLS (4 hours).
7. Non-linear models: Polynomial Regression, Regression and Smoothing Splines, Local Kernel Estimation, Generalized Additive Models. Practical examples of Non-linear modeling (4 hours).
