Probabilistic Graphical Models are a core technology for machine learning, decision making, computer vision, natural language processing and many other artificial intelligence applications. In this subject, we provide an overview of the topic. We review the formal theoretical foundations and we study how to put them in practice in order to solve problems of your interest.

Teaching methodology

Lectures dynamically combine master explanations and problem solving. The weekly schedule of in-person activities is distributed in three hours. Some slots may be exclusively dedicated to programming throughout directed activities or notebooks.
The students will be required to present an application of PGMs (their own or other people's) to problems of their interest, or a recently proposed PGM technique.

Evaluation methodology

The subject is expected to be evaluated based on a final exam (40%), a presentation (30%) and in-class activities (30%).
