Course Syllabus
Sustainable Development Goals
Aims
The aim of this course is to provide the theoretical foundations of Statistics and indicate how the theory sheds light on the properties of practical methods used in AI. The topics include estimation, prediction, testing, confidence sets, and the general approach to statistical modeling and learning, with some exposure to robust statistical inference.
Contents
The course consists of a theoretical part, with applications on data using the R software environment. Statistical Inference and statistical modeling are presented, with a view on modern methods for supervised and unsupervised learning widely employed in AI.
Detailed program
- Crash course: Quick review of basic probability theory, and on Statistical inference to recall Interval estimation and Hypothesis testing.
- Simple linear regression: least squares estimation method
- Multiple linear regression: least squares estimation method, model adequacy measures, sampling distribution of OLS estimators, hypothesis tests and confidence intervals for the regression coefficients, analysis of variance, outliers and influential observations, robust linear regression.
- Linear models for regression and for classification
- Lasso and Ridge regression, the selection of the model
- Robust statistical modeling
- Unsupervised learning: model-based clustering, latent variables, PCA and factor analysis.
Prerequisites
Statistics background: basis of probability theory and knowledge of the most relevant continuous and discrete random variables.
Mathematics background: linear algebra, matrix theory and advanced calculus.
Teaching form
Lectures and assisted exercises.
All activities will be held face-to-face, unless further COVID-19 related restrictions are imposed.
Attendance to lectures and assisted exercises is highly recommended.

Semester
First
Assessment method
The exam consists in a written exam with three open-ended questions to assess the student's knowledge and understanding of the subject, (1h30m) jointly with the development of an application in R on real data (1h). The exam is closed book. An additional oral discussion can be requested by the lecturer.
