科学领域:

神经科学是一个神经科学.
生物医学工程生物医学工程
机器学习机器学习

背景情况:

电脑电图 (EEG) 在神经科学和临床环境中至关重要,但在数据统一性,噪音和标签方面面临挑战.
开发用于从未标记的EEG中提取可概括的时空表征的方法对于推进其应用至关重要.

研究的目的:

引入DMAE-EEG,这是一个消除噪音的蒙面自动编码框架,用于从大型未标记的EEG数据集中挖掘可概括的时空表示.
解决EEG数据质量和标签方面的局限性,以改善下游任务性能.

主要方法:

提出了一个大脑区域拓异质性 (BRTH) 方法,用于非统一的EEG数据分区.
设计了一个被拒绝的伪标签生成器 (DPLG),使用一个被拒绝的重建借口任务来学习强大的表示.
利用一个不对称的自编码器,以自我注意作为骨干,在14个公共EEG数据集中捕获远程时空依赖.

主要成果:

与统计方法相比,DMAE-EEG显著提高了EEG信号质量,将正常化平均平方误差 (nMSE) 降低了27.78%-50.00%.
在运动意图识别和平衡准确度方面取得了2.71%-6.14%的相对改善,超过了最先进的方法.
在会议,科目和任务之间展示了增强的知识可转移性.

结论:

DMAE-EEG有效地从大量未标记的EEG数据中捕获可概括的时空表示.
该框架通过提高数据实用性和模型通用性来推进EEG辅助诊断,脑计算机接口和临床实践.
