Abstract EN
Wearable sensor based human physical activity recognition has extensive applications in many fields such as physical training and health care.
This paper will be focused on the development of highly efficient approach for daily human activity recognition by a triaxial accelerometer.
In the proposed approach, a number of features, including the tilt angle, the signal magnitude area (SMA), and the wavelet energy, are extracted from the raw measurement signal via the time domain, the frequency domain, and the time-frequency domain analysis.
A nonlinear kernel discriminant analysis (KDA) scheme is introduced to enhance the discrimination between different activities.
Extreme learning machine (ELM) is proposed as a novel activity recognition algorithm.
Experimental results show that the proposed KDA based ELM classifier can achieve superior recognition performance with higher accuracy and faster learning speed than the back-propagation (BP) and the support vector machine (SVM) algorithms.
