SINEW 15 2023

The SINEW 15 2023 Biomarker dataset was extracted from the sensor data collected by a longitudinal study called Sensors IN-home for Elder Wellbeing (SINEW).As the name suggested, the SINEW 15 2023 Biomarker dataset consists of 15 high-level biomarker features, derived from raw sensor readings. They cover four basic aspects of daily living, namely physical, activity, cognitive, and sleep, of each participant over a specific period. The digital biomarkers are of significance, as they can be used for early detection of mild cognitive impairment (MCI), providing an opportunity for timely intervention before it progresses to Alzheimer's disease.For the purpose of training and evaluating machine-learning-based predictive models for MCI detection, each of the biomarker records is tagged with the cognitive status - either mild cognitive impairment (MCI) or normal cognition (NC) according to the participant's closest clinical assessments within a six month period from the date the sensor data are captured.Altogether, three data sets are provided in this release, namelySINEW 15 2023 Daily Biomarker data set, consisting of records of daily biomarker feature values tagged with the corresponding cognitive status labels;SINEW 15 2023 Weekly Biomarker data set, consisting of records of weekly averaged biomarker values tagged with the corresponding cognitive status labels; andSINEW 15 2023 Monthly Biomarker data set, consisting of records of monthly averaged biomarker values tagged with the corresponding cognitive status labels.Each record/row in the three biomarker data sets contains 15 biomarker feature values as inputs and a cognitive class label (MCI vs NC) as outputs.

SINEW 15 2023 生物标志物数据集源自于名为“家庭环境传感器监测老年人福祉”（SINEW）的纵向研究所收集的传感器数据。正如其名所示，SINEW 15 2023 生物标志物数据集包含15个高级生物标志物特征，这些特征由原始传感器读数推导而来。这些特征涵盖了日常生活四个基本方面：生理、活动、认知和睡眠，涉及每位参与者在特定时间段内的状况。这些数字生物标志物具有重要意义，因为它们可用于轻微认知障碍（MCI）的早期检测，为在疾病进展至阿尔茨海默病之前及时干预提供了可能。为了训练和评估基于机器学习的MCI检测预测模型，每个生物标志物记录都根据参与者在传感器数据采集日期前后六个月内的最接近临床评估，被标记为认知状态——要么是轻微认知障碍（MCI），要么是正常认知（NC）。本发行版共提供三个数据集，分别是SINEW 15 2023 日生物标志物数据集，包含带有相应认知状态标签的每日生物标志物特征值记录；SINEW 15 2023 周生物标志物数据集，包含带有相应认知状态标签的每周平均生物标志物值记录；以及SINEW 15 2023 月生物标志物数据集，包含带有相应认知状态标签的每月平均生物标志物值记录。这三个生物标志物数据集中的每条记录/行均包含15个生物标志物特征值作为输入，以及一个认知类别标签（MCI 对比 NC）作为输出。
