Most spatiotemporal filtering methods for the problem of single-trial event-related potentials (ERP) estimation relies on the analysis of the second-order statistics (SOS) of electroencephalograph (EEG) data. Due to the noisy nature of EEG, these methods often suffer from the outliers in EEG. We combine a recently proposed spatiotemporal filtering method with the maximum correntropy criterion (MCC) for the single-trial estimation of the ERP amplitude. Study with real cognitive ERP data shows the robustness of the method with reduced estimation variance.
大多数用于单次试验事件相关电位(ERP)估计问题的时空滤波方法依赖于对脑电图(EEG)数据的二阶统计量(SOS)进行分析。由于EEG具有噪声特性,这些方法经常受到EEG中异常值的影响。我们将最近提出的一种时空滤波方法与最大相关熵准则(MCC)相结合,用于ERP幅度的单次试验估计。对真实认知ERP数据的研究表明了该方法的稳健性,其估计方差有所降低。
