A Comprehensive Survey On Client Selections in Federated Learning
Ala Gouissem Zina Chkirbene Ridha Hamila
Federated Learning (FL) is a rapidly growing field in machine learning that
allows data to be trained across multiple decentralized devices. The selection
of clients to participate in the training process is a critical factor for the
performance of the overall system. In this survey, we provide a comprehensive
overview of the state-of-the-art client selection techniques in FL, including
their strengths and limitations, as well as the challenges and open issues that
need to be addressed. We cover conventional selection techniques such as random
selection where all or partial random of clients is used for the trained. We
also cover performance-aware selections and as well as resource-aware
selections for resource-constrained networks and heterogeneous networks. We
also discuss the usage of client selection in model security enhancement.
Lastly, we discuss open issues and challenges related to clients selection in
dynamic constrained, and heterogeneous networks.
