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.

本数据集包含心冲击图（Ballistocardiography，BCG）信号。
该BCG传感器数据集的采集对象为20名受试个体。数据采集始于每位受试者卧床之时，止于其苏醒之后，因此每份数据集均包含睡眠状态下个体的BCG信号数据。本次实验使用的压电陶瓷BCG传感器由捷克赫拉德茨-克拉洛韦大学（University of Hradec Králové, Czech Republic）研制，共在床垫下方布设4台传感器，采样频率为330 Hz。数据采集实验在捷克俄斯特拉发大学（University of Ostrava, Czech Republic）的实验室中完成。后续对采集到的数据进行了预处理：X.pickle文件存储了经卡尔丹曲率（Cartan Curvature）与欧几里得弧长（Euclidean arc length）处理后的信号；y.pickle文件则存储了类别标签，即信号所属受试者的ID。
