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.该数据集包含球式心电信号。 球式心电传感器数据集由二十位测试个体提供。数据采集始于每位受试者平躺于床上的时刻，终止于其醒来之后，因此每个数据集均包含了睡眠个体的球式心电数据。本研究所采用的球式心电传感器由捷克共和国赫拉德茨-克ralove大学的制造，其采样频率为330赫兹。测量活动在捷克共和国奥斯特拉瓦大学的实验室中进行。数据经过处理之后，文件X.pickle包含了使用Cartan曲率和欧几里得弧长进行预处理后的信号，而文件y.pickle则包含了类别标签，即信号持有者的ID。
