The aim of machine learning is the development of theories, techniques and algorithms to allow a computer system to modify its behavior in a given environment through inductive inference. The goal is to infer practical solutions to difficult problems --for which a direct approach is not feasible-- based on observed data about a phenomenon or process. Machine learning is a meeting point of different disciplines: statistics, optimization and algorithmics, among others.

The course is divided into conceptual parts, corresponding to several kinds of fundamental tasks: supervised learning (classification and regression) and unsupervised learning (clustering, density estimation). Specific modelling techniques studied include artificial neural networks and support vector machines. An additional goal is getting acquainted with python and its powerful machine learning libraries.

Teaching methodology

The course introduces the most important concepts in machine learning and its most relevant techniques with a solid foundation in math. All the theory and concepts are illustrated and accompanied by real-world examples and code using open source libraries.

The theory is introduced in lectures where the teacher exposes the concepts, and during the lab sessions students will see many examples on how to apply the methods and theory learned, as well as code their own solutions to exercises proposed by the teacher.

Students have to work on a course project using a real-world dataset.

Evaluation methodology

The course is graded as follows:

P = Grade of mid-term test-type exam
F = Score of the final exam
L = Score for the practical work

final grade = 20% P + 40% F + 40% L

Contingency plan

Passaríem a fer les sessions de laboratori de forma remota, amb sessions de videoconferència per aclarir dubtes. Les classes de teoria es farien no presencialment mitjançant la publicació de vídeos i sessions de videoconferència gravades./ The laboratory sessions would be done remotely, with videoconferencing sessions to clarify doubts. The theory classes would be done through the publication of videos and recorded videoconference sessions.
