摘要

现代社会面临着全球人口老龄化的重大挑战。到2030年,老年人数量预计将超过14亿,这无疑将影响当前公共和私营部门医疗保健系统的可持续性。为了解决老年人在不正常的家庭行为或意外跌倒方面经常面临的一些健康问题,基于传感器的人类活动识别和自动跌倒检测系统已成为可用于立即通知护理人员的宝贵工具。这些系统可以监测老年人的健康状况,促进健康的生活方式,并提供及时的医疗干预,从而改善恢复和康复。在本文中,我们提出了一种深度学习模型,该模型利用移动传感器的可负担性和最新技术进步来识别某些身体活动,并在跌倒时及时发送警报。我们的混合模型结合了卷积神经网络在特征提取方面的优势和长短期记忆网络在时间序列预测和分类方面的优势。通过在两个公共数据集上的实验,我们证明了我们的方法的有效性,在识别人类活动和检测跌倒方面取得了优异的性能,超过了类似研究的性能。

A Hybrid Deep Learning Model for Human Activity Recognition and Fall Detection for the Elderly
Modern society faces a significant challenge with the aging of the global population. The number of seniors is projected to surpass 1.4 billion by 2030, which will undoubtedly impact the sustainability of current healthcare systems, both in the public and the private sectors. To address some health issues that often face the elderly in terms of abnormal home behavior, or accidental falls, sensor-based systems for human activity recognition and automatic fall detection have become valuable tools which can be used for immediate notification to caregivers. These systems can monitor the health status of elderly individuals, promote healthy lifestyles, and provide timely medical intervention, leading to improved recovery and rehabilitation. In this paper, we propose a deep learning model that takes advantage of the affordability and latest technological advancements of mobile sensors to identify certain physical activities and promptly send an alert in the event of a fall. Our hybrid model combines the strength of Convolutional Neural Networks for feature extraction with the advantages of Long Short-Term Memory networks for time series forecasting and classification. Through experiments on two public datasets, we demonstrate the effectiveness of our approach, achieving superior performance in recognizing human activities and a high accuracy for fall detection, surpassing the performance of similar studies.
