title: Machine Learning-Based Classification of Human Behaviors and Falls in Restroom via Dual Doppler Radar Measurements
abstract: This study presents a radar-based remote measurement system for classification of human behaviors and falls in restrooms without privacy invasion. Our system uses a dual Doppler radar mounted onto a restroom ceiling and wall. Machine learning methods, including the convolutional neural network (CNN), long short-term memory, support vector machine, and random forest methods, are applied to the Doppler radar data to verify the model's efficiency and features. Experimental results from 21 participa
