Learning outcomes

The goal of the course is to provide students with mathematical, statistical and computational tools for a rigorous understanding of machine learning. A central aspect is the critical discussion of how and to which extent machine learning methods are essential in large scale data analysis in order to develop a professional profile combining solid quantitative skills with an in-depth knowledge of economic and corporate dynamics to support strategic decisions based on data analysis. At the end of the course students will be able to master classical methods of machine learning, implement data analysis algorithms, choose the most suitable techniques, identify relevant structures underlying the data for prediction purposes, critically discuss the output generated by a machine learning technique.

Examination Methods

The exam will test for
(a) the understanding of the theoretical tools (concepts and formal models) presented in the course,
(b) the ability to use theoretical tools to discuss results from a data set analysis.

The final exam will consist of two parts:
- a written exam on the material of the lab sessions. During the course candidates will have the opportunity to
solve two partial assignments that will be part of the final evaluation. Alternatively, there will be one general
assignment due before the oral exam on a date to be communicated later on,
- an oral test on the theoretical lectures of the course.
