Cross Device Federated Learning
Cross-device federated learning (FL) aims to train machine learning models collaboratively across numerous mobile devices without directly sharing their private data. Current research emphasizes improving efficiency and robustness by addressing challenges like asynchronous updates, heterogeneous device capabilities, and imbalanced data distributions, often employing techniques such as secure aggregation, adaptive partial training, and novel optimization algorithms like stochastic proximal point methods. This field is significant for enabling privacy-preserving large-scale model training in diverse applications, particularly in mobile health and personalized services, while also pushing the boundaries of distributed systems and optimization theory.
