Description
Athina Tsanousa and colleagues detect room occupancy by fusing the readings of ordinary environmental sensors on a live construction site. Smart building systems sense temperature, dust, and air quality for energy efficiency, but combined cleverly, the same sensors can infer whether people are present, aiding security and safety. The study evaluates sensor fusion strategies on data from a building under construction.
The authors compare several late fusion methods, which combine each sensor stream's calls, against early fusion feeding ensemble classifiers. They also test a novel weighted fusion method built for lopsided samples, key because empty periods dominate occupancy data. The dataset collected from the site's sensors is released in public. Occupancy from such sensors is in effect free information: no cameras, no wearables, no new hardware.
