AI总结:

针对EEG数据噪声高且现有预处理难以支撑大规模自监督学习的问题,提出Python预处理流程,优化后稳定训练并提升下游任务性能。

摘要:

脑电图(EEG)研究通常聚焦于目标狭窄的任务,但近期研究正扩展至在更大模型中使用未标注数据,旨在实现更广泛的应用。这解决了EEG研究中的一个关键挑战。例如,Kostas等人(2021)表明,自监督学习(SSL)优于传统监督方法。鉴于EEG数据中的高噪声水平,我们认为通过额外的预处理可以进一步改进。当前的预处理方法往往因缺乏优化、依赖主观人工校正、验证流程或限制SSL的僵化协议,而无法高效管理SSL所需的大规模数据。我们提出一个基于Python的EEG预处理流程,专为自监督学习优化,旨在高效处理大规模数据。这种优化不仅稳定了自监督训练,还相较于使用原始数据训练,提升了下游任务的性能。

英文摘要:

Electroencephalography (EEG) research typically focuses on tasks with narrowly defined objectives, but recent studies are expanding into the use of unlabeled data within larger models, aiming for a broader range of applications. This addresses a critical challenge in EEG research. For example, Kostas et al. (2021) show that self-supervised learning (SSL) outperforms traditional supervised methods. Given the high noise levels in EEG data, we argue that further improvements are possible with additional preprocessing. Current preprocessing methods often fail to efficiently manage the large data volumes required for SSL, due to their lack of optimization, reliance on subjective manual corrections, and validation processes or inflexible protocols that limit SSL. We propose a Python-based EEG preprocessing pipeline optimized for self-supervised learning, designed to efficiently process large-scale data. This optimization not only stabilizes self-supervised training but also enhances performance on downstream tasks compared to training with raw data.
