Journal ArticleDOI
WiFi CSI Based Passive Human Activity Recognition Using Attention Based BLSTM
TL;DR: This paper proposes a new deep learning based approach, i.e., attention based bi-directional long short-term memory (ABLSTM) for passive human activity recognition using WiFi CSI signals, employed to learn representative features in two directions from raw sequential CSI measurements.
Journal ArticleDOI
Building occupancy estimation and detection: A review
TL;DR: A comprehensive review on building occupancy estimation and detection is presented and some potential future research directions are indicated based on current progresses of the systems.
Journal ArticleDOI
Indoor occupancy estimation from carbon dioxide concentration
TL;DR: It is found that pre-smoothing the CO2 data can greatly improve the estimation accuracy and a new criterion, i.e. $x$-tolerance accuracy, is introduced to assess the occupancy estimator.
Journal ArticleDOI
A Novel Ensemble ELM for Human Activity Recognition Using Smartphone Sensors
TL;DR: The experimental results indicate that the proposed ensemble ELM approach outperforms some state-of-the-art approaches and can achieve recognition accuracies of $\text{97.35}\%$ and $\ text{98.88}$ on two datasets.
Journal ArticleDOI
Smartphone Sensor-Based Human Activity Recognition Using Feature Fusion and Maximum Full a Posteriori
TL;DR: This article proposes a feature fusion framework to combine handcrafted features with automatically learned features by a deep algorithm for HAR and develops a maximum full a posteriori algorithm to further enhance the performance of HAR.
