Enhancing Robustness of Federated Learning via Server Learning

arXiv – CS AI|Van Sy Mai, Kushal Chakrabarti, Richard J. La, Dipankar Maity|
🤖AI Summary

Researchers propose a new heuristic algorithm combining server learning with client update filtering and geometric median aggregation to improve federated learning robustness against malicious attacks. The approach maintains model accuracy even when over 50% of clients are malicious and works with non-identical data distributions across clients.

Key Takeaways
  • New algorithm enhances federated learning security through server learning and client update filtering.
  • System maintains accuracy even when more than 50% of participating clients are malicious.
  • Approach works effectively with non-independent and non-identically distributed client data.
  • Server can use small or synthetic datasets that don't need to match client data distributions.
  • Combines geometric median aggregation with filtering to improve robustness against attacks.
