Santa Fe Time Series Competition Data Set B

This is a multivariate data set recorded from a patient in the sleep laboratory of the Beth Israel Hospital (now the Beth Israel Deaconess Medical Center) in Boston, Massachusetts. This data set was extracted from record slp60 of the MIT-BIH Polysomnographic Database, and it was submitted to the Santa Fe Time Series Competition in 1991 by our group. The data are presented in text form and have been split into two sequential parts, b1.txt and b2.txt. Each line contains simultaneous samples of three parameters; the interval between samples in successive lines is 0.5 seconds. The first column is the heart rate, the second is the chest volume (respiration force), and the third is the blood oxygen concentration (measured by ear oximetry). The sampling frequency for each measurement is 2 Hz (i.e., the time interval between measurements in successive rows is 0.5 seconds).本数据集为多变量数据集，采集自马萨诸塞州波士顿市贝斯以色列医院（现贝斯以色列女执事医疗中心）睡眠实验室的一名患者。本数据集提取自MIT-BIH多导睡眠图（Polysomnographic）数据库的slp60记录，并于1991年由我们团队提交至圣达菲时间序列竞赛。数据集以文本格式呈现，并被拆分为两个连续的分段文件：b1.txt与b2.txt。每一行包含三个参数的同步采样数据；相邻行的采样间隔为0.5秒。第一列为心率，第二列为胸腔容积（呼吸力量），第三列为血氧浓度（通过耳式血氧仪测得）。各测量项的采样频率均为2 Hz（即相邻行的测量间隔为0.5秒）。

背景与挑战

背景概述

该数据集是一个多变量生理时间序列数据集，记录于睡眠实验室，包含心率、呼吸力和血氧浓度三个参数，采样频率为2 Hz，用于研究睡眠呼吸暂停和心率变异性等问题。数据分为两个文件，每行包含同步样本，时间间隔为0.5秒，并附有睡眠阶段标注，适用于时间序列预测和生理信号分析研究。
