Ballistocardiography sleep dataset
Tha dataset contains ballistocardiography signals. The BCG sensor dataset is obtained from twenty tested individuals. The data collection started when each idnividual lied in the bed and stopped after waking up therefore each dataset contains BCG data of sleeping persons. We used piezoceramic BCG sensors made by Univesity of Hradec Králové, Czech Republic. Four sensors placed under the mattress were used with sampling frequency 330 Hz. Measurement took place in laboratory at University of Ostrava, Czech republic. The data was then processed, the file X.pickle includes the signals after preprocessing using the Cartan Curvature and the Euclidean arc length. The file y.pickle has the class labels, which are the ID of signal holders.
