Title: Federated Learning: Architectures, Key Algorithms, and Future Outlook


In the era of Internet of Things and Big Data, large volumes of data has been generated by millions of mobile devices and sensors at the edge of the Internet on a daily basis. Resolving the conflict between the need for
analyzing such data and the requirements for preserving user privacy has always been a balancing act. Federated learning, as a distributed learning paradigm involving both the edge and the cloud, has been touted in the recent years as a suitable way to achieve a balanced trade-off between using data and preserving data privacy. It offers us the best of both worlds: privacy-preserving training of machine learning models. Yet, by performing local training and collecting model updates from edge devices, federated learning incurred a large amount of communication overhead, and has to address the problems of systems and statistical heterogeneity. In this talk, we take a deep dive in the current challenges of federated learning, present our a preview of our preliminary work, and offer fresh
insights on future research that is urgently needed in this topic.
