Abstract
Techniques for presence detection based on multi modal sensors are described. In an example, a computer system determines first data indicating a first prediction of presence detection within a space. The first data is generated based on first sensor data. The computer system determines second data indicating a second prediction of presence detection within the space. The second data is generated based on second sensor data. The second sensor data is of a different type than the first sensor data. The computer system generates third data indicating a third prediction of presence detection within the space based on the first data, the second data, and a fusion model. The fusion model is configured to generate the third data by at least using associations between presence detections, latent variables, and observed variables. The observed variables correspond to the first data and the second data. The latent variables include sensor-triggering events.
