Human Activity Classification Using Multilayer Perceptron

Sensors (Basel). 2021 Sep 16;21(18):6207. doi: 10.3390/s21186207.

Abstract

The number of smart homes is rapidly increasing. Smart homes typically feature functions such as voice-activated functions, automation, monitoring, and tracking events. Besides comfort and convenience, the integration of smart home functionality with data processing methods can provide valuable information about the well-being of the smart home residence. This study is aimed at taking the data analysis within smart homes beyond occupancy monitoring and fall detection. This work uses a multilayer perceptron neural network to recognize multiple human activities from wrist- and ankle-worn devices. The developed models show very high recognition accuracy across all activity classes. The cross-validation results indicate accuracy levels above 98% across all models, and scoring evaluation methods only resulted in an average accuracy reduction of 10%.

Keywords: artificial neural network (ANN); human activity recognition; intelligent buildings (IB); smart home (SH).
