摘要:

本研究探讨了一种混合集中-联邦方法,用于使用移动传感器数据进行人类活动识别(HAR)。随着边缘设备如智能手机和可穿戴设备的普及,大量来自可穿戴和惯性传感器的私人数据被生成,从而实现了对人类活动(如休息、睡眠和行走)的 discreet 监测。本研究专注于部署HAR技术,并利用Flower框架内的联邦学习来评估基于集中基线的联邦模型的训练。实验结果表明,所提出的混合方法在非IID数据场景下提高了HAR模型的准确性和鲁棒性,同时在保护数据隐私方面有效。联邦学习设置显示了与集中模型相当的性能,突显了联邦学习在现实应用中在数据隐私和模型性能之间取得平衡的潜力。

英文摘要:

The study explores a hybrid centralized-federated approach for Human Activity Recognition (HAR) using a Transformer-based architecture. With the increasing ubiquity of edge devices, such as smartphones and wearables, a significant amount of private data from wearable and inertial sensors is generated, facilitating discreet monitoring of human activities, including resting, sleeping, and walking. This research focuses on deploying HAR technologies using mobile sensor data and leveraging Federated Learning within the Flower framework to evaluate the training of a federated model derived from a centralized baseline. The experimental results demonstrate the effectiveness of the proposed hybrid approach in improving the accuracy and robustness of HAR models while preserving data privacy in a non-IID data scenario. The federated learning setup demonstrated comparable performance to centralized models, highlighting the potential of federated learning to strike a balance between data privacy and model performance in real-world applications.
