Learning activities and methodology

Theory: Lectures will be focused on teaching all concepts related to neural networks, so that students acquire knowledge on artificial neural networks necessary for professional development (PO: a, e, k) and they will be carried out in synchronous on-line mode.
Practical sessions (small groups): The practical classes will be developed so that, in a supervised way, students learn to solve real problems with artificial neural networks. The practices will be carried out in groups of 2 students, enhancing teamwork (PO: b, d, e, g, k) (Soft-skill: teamwork). They will be held in synchronous on-line mode, except for 5 sessions that will be in-class. These sessions will be devoted to evaluation, the presentation of the practices and the discussion and sharing on the progress of the practices.
The weekly planification shows the exact distribution for each activity.
