摘要:

人类活动识别(Human Activity Recognition,HAR)是指机器感知人类行为的能力。HAR是先进的机器学习和人工智能技术的一个突出应用,这些技术利用计算机视觉来理解异构人类行为的语义含义。本文描述了一种监督学习方法,该方法可以根据从实际人体运动中收集的数据来区分人体动作。使用HAR时的主要挑战是克服活动信号的循环平稳性质带来的困难。提出了一种基于双通道卷积神经网络(CNN)的HAR分类模型,该模型利用了所采集的人体动作信号的频率和功率特征。该模型在UCI HAR数据集上进行了测试,分类准确率为95.25%。该方法将有助于进一步研究基于生物医学信号的人体活动识别。

英文摘要:

Human Activity Recognition (HAR) simply refers to the capacity of a machine to perceive human actions. HAR is a prominent application of advanced Machine Learning and Artificial Intelligence techniques that utilize computer vision to understand the semantic meanings of heterogeneous human actions. This paper describes a supervised learning method that can distinguish human actions based on data collected from practical human movements. The primary challenge while working with HAR is to overcome the difficulties that come with the cyclostationary nature of the activity signals. This study proposes a HAR classification model based on a two-channel Convolutional Neural Network (CNN) that makes use of the frequency and power features of the collected human action signals. The model was tested on the UCI HAR dataset, which resulted in a 95.25% classification accuracy. This approach will help to conduct further researches on the recognition of human activities based on their biomedical signals.
