报告主要内容：
With the rapid development of the Internet-of-Things (IoT), data from intelligent devices is exploding at unprecedented scales. Motivated by the advancing computational capacity of wireless end-user equipment (UE), as well as the increasing concerns about sharing private data, a new machine learning paradigm, namely federated learning (FL), has emerged with increasing attentions. FL allows a decoupling of data provision at UEs and model aggregation at a central server, and thus begins to show its potential advantages in many practical areas. In this talk, we focus on FL with resource-constrained settings, performing fundamental analysis on FL convergence, as well as framework design and optimizations. Specifically, the talk mainly consists of three parts. First, from security perspective, we discuss on FL with differential privacy and external model attacks. Then, we introduce a decentralized FL based on blockchain to combat one-point failure issue, followed by performance analysis and solution to model plagiarism problem. In addition, we consider two FL frameworks in wireless scenarios, and improve FL learning performance by jointly optimizing computing and communication resources. As a conclusion of this talk, we will present some possible challenges and future directions in FL.
