Machine Learning Techniques for Sensor-Based Human Activity Recognition with Data Heterogeneity—A Review
Xiaozhou Ye, Kouichi Sakurai, Nirmal-Kumar C. Nair, Kevin I-Kai Wang
Sensor-based Human Activity Recognition (HAR) is crucial in ubiquitous computing, analyzing behaviors through multi-dimensional observations. Despite research progress, HAR confronts challenges, particularly in data distribution assumptions. Most studies assume uniform data distr…
