Asynchronous Federated Learning for Sensor Data with Concept Drift

no code implementations1 Sep 2021 Yujing Chen, Zheng Chai, Yue Cheng, Huzefa Rangwala

We propose a novel approach, FedConD, to detect and deal with the concept drift on local devices and minimize the effect on the performance of models in asynchronous FL.

Asynchronous Online Federated Learning for Edge Devices with Non-IID Data

no code implementations5 Nov 2019 Yujing Chen, Yue Ning, Martin Slawski, Huzefa Rangwala

In this paper, we present an Asynchronous Online Federated Learning (ASO-Fed) framework, where the edge devices perform online learning with continuous streaming local data and a central server aggregates model parameters from clients.

Federated Multi-task Hierarchical Attention Model for Sensor Analytics

no code implementations13 May 2019 Yujing Chen, Yue Ning, Zheng Chai, Huzefa Rangwala

The attention mechanism of the proposed model seeks to extract feature representations from the input and learn a shared representation focused on time dimensions across multiple sensors.
