An On-Device Learning Approach and Its Extension for Federated Learning

Abstract

Most edge AI focuses on prediction tasks on resource-limited edge devices, while the training is done at server machines, so retraining a model on the edge devices to reflect environmental changes is a complicated task. To follow such environmental changes, a neural-network based on-device learning approach is recently proposed, so that edge devices can train incoming data at runtime to update their model. However, since a training is done at distributed edge devices, the issue is that only a limited amount of training data can be used for each edge device. To address this issue, this talk presents an on-device federated learning for cooperative model update, where edge devices exchange their intermediate trained results and update their model by using those collected from the other edge devices.
