Abstract: The future of machine learning lies in moving both data collection as well as model training to the edge. The emerging area of federated learning seeks to achieve this goal by orchestrating distributed model training using a large number of resource-constrained mobile devices that collect data from their environment. Due to limited communication capabilities as well as privacy concerns, the data collected by these devices cannot be sent to the cloud for centralized processing. Instead, the nodes locally perform a few iterations of training and only send the resulting model to the cloud. In this talk, I will present our recent work on federated optimization algorithms that are system-aware (robust to communication limitations and computation variabilities) and data-aware (can handle heterogeneity in the size and distribution of the training data).
