- Describe physical systems using the appropriate mathematical formulation. - Apply machine-learning algorithms to the resulting problem. - Understand the advantages and limitations of machine learning algorithms given the specific problem at hand.
Prerequisiti
Introduction to physics as provided in the relevant first- and second-year classes. Basic knowledge of the Python programming language.
Metodi didattici
Each class will pair traditional lectures (to introduce the relevant problems) with hands-on exercises and demonstrations (to tackle the relevant problem). These computational activities are the key content of the course.
Verifica Apprendimento
Students will develop a series of computational projects. These will be started during the lectures and completed asynchronously. The project report and associate codes, likely in the form of a Jupyter notebook, will then be submitted for evaluation.
