鲁棒是Robust的音译,也就是健壮和强壮的意思。它也是在异常和危险情况下系统生存的能力。比如说,计算机软件在输入错误、磁盘故障、网络过载或有意攻击情况下,能否不死机、不崩溃,就是该软件的鲁棒性。所谓“鲁棒性”,也是指控制系统在一定(结构,大小)的参数摄动下,维持其它某些性能的特性。根据对性能的不同定义,可分为稳定鲁棒性和性能鲁棒性。以闭环系统的鲁棒性作为目标设计得到的固定控制器称为鲁棒控制器。

Today data is often scattered among billions of resource-constrained edge devices with security and privacy constraints. Federated Learning (FL) has emerged as a viable solution to learn a global model while keeping data private, but the model complexity of FL is impeded by the computation resources of edge nodes. In this work, we investigate a novel paradigm to take advantage of a powerful server model to break through model capacity in FL. By selectively learning from multiple teacher clients and itself, a server model develops in-depth knowledge and transfers its knowledge back to clients in return to boost their respective performance. Our proposed framework achieves superior performance on both server and client models and provides several advantages in a unified framework, including flexibility for heterogeneous client architectures, robustness to poisoning attacks, and communication efficiency between clients and server. By bridging FL effectively with larger server model training, our proposed paradigm paves ways for robust and continual knowledge accumulation from distributed and private data.
