Abstract: Federated Learning (FL) is a popular solution to distributedly train a model on user devices improving user privacy and system scalability. However, 3rd party developers are still lacking practical systems that would enable easy, collaborative, cross-device, and cross-app FL training in the context of mobile environments.
In this talk, I will present our attempt to bridge this gap with a novel end-to-end system that enables intra- and inter-app training on mobile devices with different types of IID and NonIID data distributions, in a secure and easy to deploy fashion. Moreover, I will talk about how Trusted Execution Environments (TEEs) could be utilized on clients for local training, and on servers for secure aggregation, so that model/gradient updates are protected from adversaries.
Meet the Speaker
Dr Kleomenis Katevas is a Machine Learning Researcher and lead of the ML research team at Brave Software where he is focused on designing and building privacy-preserving, ML-based systems. His research interests lie in the areas of Privacy-Preserving Machine Learning, Mobile Systems, and Efficient On-Device ML. He holds a PhD and an MSc from Queen Mary University of London, UK. In the past he has worked as a Research Scientist at Telefonica Research, Barcelona, a Research Associate in the Dyson School of Design Engineering at Imperial College London, UK, a Research Assistant at Queen Mary University of London, UK, and an R&D Engineer at Philips Healthcare (formerly Philips Medical Systems) in Germany. He was also a Co-founder and CTO of Hiver, a London Business School (LBS) startup that analysed the human interactions in social events using mobile sensing technology.
