Let's Focus: Focused Backdoor Attack against Federated Transfer Learning

arXiv:2404.19420v1 Announce Type: cross
Abstract: Federated Transfer Learning (FTL) is the most general variation of Federated Learning. According to this distributed paradigm, a feature learning pre-step is commonly carried out by only one party, typically the server, on publicly shared data.
