Distributed Edge Intelligence for AI-empowered Applications

System Architecture of E-tree

Distributed Edge Intelligence for Pedestrian Re-Identification

Overview

We focus on distributed edge intelligence for AI-empowered applications. We develop new training solution, E-tree learning, that leverages the tree structure imposed on the edge devices. The tree structure, locations and orders of aggregation on the tree are optimally designed to reduce the synchronization time and improve the efficiency of training. Evaluation results shows that E-tree learning outperforms than existing federated learning and Gossip learning approaches in convergency and model accuracy. We also work on distributed edge inference by develop a platform for deploying AI models for mission-critical applications like collaborative real-time video surveillance. Our designed platform also includes a scheduler that offloads the AI models used for pedestrian re-identification to reduce the latency and enable computation sharing among devices.
