In the era of AI and mobile Internet, federated learning (FL) over mobile devices, one of the most anticipated technologies, has fostered numerous intriguing applications and services, while many of them are energy-hungry and delay-sensitive. In this talk, I would like to discuss our proposed energy/delay efficient FL designs over mobile devices. Different from most existing communication efficient FL designs, which regard wireless communications as the bottleneck, we have an interesting observation that under many typical FL settings, the local computing energy/ delay is comparable to the communication energy/delay during the FL training process, given the development of high-speed wireless transmission techniques (e.g., 4G LTE, 5G, Wi-Fi 5 or Wi-Fi 6). Thus, the total energy/delay should be computing energy/delay + communication energy/delay over training rounds in FL. To effectively reduce the overall energy/delay of FL over mobile devices, simply reducing local computing/communication energy/delay independently is not enough, and the energy/delay trade-off between "working" (i.e., local computing) and "talking" (i.e., wireless communications) has to be considered. To study this trade-off, we have initially modeled and empirically studied the impacts of advanced local computing control (e.g., DVFS, local iteration number), compression (e.g., gradient quantization, gradient sparsification) and wireless transmission (e.g., transmission rates) strategies on computing and communication energy/delay, formulated the problem of efficient FL over mobile devices, and provided feasible
solutions. We have also set up a testbed of FL over mobile devices with Lambda server, Nvidia TX2s/Xaviers and NI USRPs to validate our analysis, and shown promising experimental results. If time allowed, I will briefly talk about our efficient design of differential privacy preserving FL, which is implemented in a piggyback manner.
