Distributed and Federated Learning

Code UE : USEES3

  • Cours
  • 5 crédits

Responsable(s)

Stefano SECCI

Public, conditions d’accès et prérequis

  • Students are required to have taken an introductory machine-learning course 
  • Good knowledge on supervised learning. 
  • Some knowledge on Gradient descent 
  • Bases on unsupervised learning is recommended, but this is not a prerequisite. 

Objectifs pédagogiques

This course provides an overview of federated and distributed learning in terms of performance and sécurité.  Both theoretical and practical aspects will be extensively explored in this course in order to acquire solid expertise on both aspects. By the end of the course, students should 
  • Understand the major difference between centralized and decentralized learning 
  • Understand the methods most commonly used in federated learning 
  • Understand the performance of federated learning when data is heterogeneous (Non-IID data). 
  • Be able to build and scale a simple federated system 
  • Have acquired competence in implementing federated learning in the fields of networks, security, health or others. 

Contenu

This course is designed to extend students' knowledge of learning in a decentralized setting. Decentralized learning techniques, such as federated learning, are set to deliver a new generation of machine learning applications by enabling efficient and reliable learning between multiple parties and from diverse data sources.  This course will cover different aspects of federated learning, focusing on recent research developments and exploring important applications in different fields such as security, networks and healthcare. 
Lectures

  Complementary content:  
  • Threats, attacks, and defenses to federated learning   
  • Designing an attack and setting up a defense for federated learning. 
  • Applications to Images, Networks, health, and vehicle-to-vehicle communications  
Labs 
  • Applications of federated learning to network anomaly detection: use of 5G and LoRaWAN testbeds and datasets, with lab [by CNAM].   
  • Applications of federation learning to medical equipment: use of aggregated and anonymized field data [by NTUU].   
  • Applications of federation learning to vehicle-to-vehicle communications: routing and content offloading [by UPC]. 

Modalité d'évaluation

  • The evaluation will be based on a final exam, lab reports and/or project activity. 
  • For the project, students may also conduct research in the field of federated learning and write a short paper.
