摘要
诱发电位 (EP)和事件相关电位 (ERP)的单次提取是生物医学信号处理领域颇受关注的一个研究问题。本文综述了近年来 EP/ERP快速提取算法的一些新进展 ,主要介绍了子空间正则化、自适应斯径向基神经网络、独立分量分析和奇异性检测四种方法 ,这些方法都立足于用较少的刺激次数提取出较高质量的诱发电位或事件相关电位 ,展示了 EP/ERP快速提取的前景。
Single-trial estimation of evoked potentials(EP)and event-related potentials(ERP)is the interesting field in biomedical signal processing.Recent advance in simgle-trial EP/ERP estimation is presented in this article.Four methods,including subspace regularization,adaptive Gaussian radial basis function neural network,independent component analysis,and singularity detection technology are introduced.All of them are promising for extracting EP/ERP with fewer stimulation to attain adequate quality.
