Ogni modulo equivale a 3 crediti ECTS. È possibile scegliere un totale di 10 moduli/30 ECTS nelle seguenti categorie:
- 12-15 crediti ECTS in moduli tecnico-scientifici (TSM)
I moduli TSM trasmettono competenze tecniche specifiche del profilo e si integrano ai moduli di approfondimento decentralizzati. - 9-12 crediti ECTS in basi teoriche ampliate (FTP)
I moduli FTP trattano principalmente basi teoriche come la matematica, la fisica, la teoria dell’informazione, la chimica ecc. I moduli ampliano la competenza scientifica dello studente e contribuiscono a creare un importante sinergia tra i concetti astratti e l’applicazione fondamentale per l’innovazione - 6-9 crediti ECTS in moduli di contesto (CM)
I moduli CM trasmettono competenze supplementari in settori quali gestione delle tecnologie, economia aziendale, comunicazione, gestione dei progetti, diritto dei brevetti, diritto contrattuale ecc.

- Esame
The module will address the theoretical aspects behind the realisation of Recommendation Systems and will allow students to practice over different use case scenarios. In particular it will address the following RecSys approaches:
- Traditional and Machine Learning based recommendation
- Deep Leanrning based recommendation
- Complex networks based recommendation.
Requisiti
- Machine Learning and Data Mining,
- Python programming
- basic calculus, linear algebra and statistics concepts
Obiettivi di apprendimento
Students understand the theoretical aspects behind the realization of Recommendation Systems and they will learn how to build them over different use case scenarios.
They will learn how recommendation systems work, focusing on three different approaches:
- Traditional and Machine Learning based recommendation
- Deep Leanrning based recommendation
- Complex networks based recommendation.
They will learn how to deal with classical recommendation challenges like imbalanced data set problems, cold-start problems, and long tail problems. Additionally they will learn how to evaluate recommendation systems.
They will learn how to deal with complex networks and how to exploit network extracted information to enhance recommendation solutions.
Finally they will learn how to build multimodal recommendation systems exploiting social networks metrics and dynamics in order to deal with content spread and users engagement.
They know the current research directions within these domains.
They can reuse the material acquired in this course in their own working environment and apply them to solve their specific problems

Metodologie di insegnamento e apprendimento
Problem based learning. During the lesson the lecturer will introduce real world problems and the class will try to solve them together.
The lecturer will support the problem solving process, introducing new concepts and tools, as required.
Practical work will complement the theory, so that students can put in practice the studied arguments.
