MASS

The Montreal Archive of Sleep Studies (MASS) is an open-access and collaborative database of laboratory-based polysomnography (PSG) recordings [1-1]. Its goal is to provide a standard and easily accessible source of data for benchmarking the various systems developed to help the automation of sleep analysis. It also provides a readily available source of data for fast validation of experimental results and for exploratory analyses. Finally, it is a shared resource that can be used to foster large-scale collaborations in sleep study. MASS is composed of cohorts themselves comprising subsets. Recordings within subsets is kept as homogeneous as possible, whereas it is more heterogeneous between subsets. To allow inter-study comparisons, researchers validating their results on MASS are encouraged to specify which portion of the database they used in their assessment (e.g., MASS-C1 for the whole cohort 1, MASS-C1/SS1-SS3 for subsets 1, 2 and 3 of cohort 1).蒙特利尔睡眠研究档案馆（Montreal Archive of Sleep Studies, MASS）是一个开放获取的协作式实验室多导睡眠图（polysomnography, PSG）记录数据库[1-1]。其旨在提供一套标准化且易于获取的数据集，用于对各类旨在实现睡眠分析自动化的系统开展性能基准测试。同时，该数据集也可为实验结果的快速验证与探索性分析提供便捷可用的数据支撑。此外，它作为共享资源，可用于推动睡眠研究领域的大规模跨团队协作。MASS由多个队列组成，每个队列又包含若干子数据集。各子数据集内部的记录数据尽可能保持同质性，而不同子数据集之间则具备更高异质性。为支持不同研究间的结果对比，鼓励在MASS数据集上验证研究成果的研究者明确说明其评估过程中使用的数据库子集范围（例如，MASS-C1指代完整队列1，MASS-C1/SS1-SS3指代队列1中的子数据集1、2与3）。
