Python 2.7 is used during development and following libraries are required to run the code provided in the notebook: The Occupancy Detection dataset used, can be downloaded from the following link. Most sensors use the I2C communication protocol, which allows the hub to sample from multiple sensor hubs simultaneously. 9. Technical validation of the audio and images were done in Python with scikit-learn33 version 0.24.1, and YOLOv526 version 3.0. If nothing happens, download GitHub Desktop and try again. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Lists of dark images are stored in CSV files, organized by hub and by day. Ground-truth occupancy was obtained from time stamped pictures that were taken every minute. Occupancy detection, tracking, and estimation has a wide range of applications including improving building energy efficiency, safety, and security of the Seidel, R., Apitzsch, A. Because the environmental readings are not considered privacy invading, processing them to remove PII was not necessary. Huchuk B, Sanner S, OBrien W. Comparison of machine learning models for occupancy prediction in residential buildings using connected thermostat data. Reliability of the environmental data collection rate (system performance) was fairly good, with higher than 95% capture rate for most modalities. Performance of a k-nearest neighbors classifier on unprocessed audio (P0), and audio data as publicly available in the database (P1). To generate the different image sizes, the 112112 images were either downsized using bilinear interpolation, or up-sized by padding with a white border, to generate the desired image size. Due to the increased data available from detection sensors, machine learning models can be created and used to detect room occupancy. The code base that was developed for data collection with the HPDmobile system utilizes a standard client-server model, whereby the sensor hub is the server and the VM is the client.
