Artificial Intelligence (AI) at the edge is transforming various industries by bringing intelligence closer to where the data is generated, unlocking new possibilities for innovation and efficiency in a wide range of applications such as intelligent traffic management, remote patient monitoring, and smart agriculture. However, there are significant challenges in analysis, operation, and practical implementations of edge AI. In this talk, we will provide an overview of our recent progress in addressing these challenges and bring edge AI closer to practice. First, we consider the popular federated learning (FL) problem and propose a unified convergence analysis approach. The advantages of the proposed approach are that 1) it can be applied to many scenarios, including arbitrary client participation and unknown client participation processes that cannot be covered by other approaches, and the effect of these processes are just pluggable components that can be analyzed separately and conveniently, and 2) in many scenarios, even with weaker assumptions, the convergence rate of proposed approach matches the state of the art. Second, we consider FL system in operation, where the system resources may be constrained and have high dynamics such as mobile edge networks. We propose a novel stochastic optimization framework to jointly tune the control knobs such as client computation decisions and the model update compressions. One notable advantage of this framework is to directly minimize the convergence upper bound under system constraints and dynamics, which is formidably challenging due to the involved interplay among system parameters. Third, we consider the practical implementations of edge AI systems. In particular, we focus on our recent development and deployment of SPARC-LoRa system for smart aquiculture application. Finally, we conclude the presentation with our future research plans including building practical and scalable edge computing testbeds for everyone.
