摘要:

脑电分类是近年来被广泛应用于脑部疾病分析的一种方法。不幸的是,无效/嘈杂的EEG降低了诊断性能,大多数以前开发的方法忽略了EEG选择分类的必要性。为此,本文提出了一种新的基于最大权值聚类的脑电选择方法mwcEEGs,将脑电选择映射为从一个同时考虑边权值和顶点权值的改进的Fréchet距离加权无向脑电图中搜索最大相似权团.我们的mwcEEG通过选择具有相似性阈值$δ$的团内成对相似和团间区分EEG来提高分类性能。在真实脑电数据集上的实验结果表明,与现有的时间序列选择算法相比,该算法是有效的。

英文摘要:

Brain Electroencephalography (EEG) classification is widely applied to analyze cerebral diseases in recent years. Unfortunately, invalid/noisy EEGs degrade the diagnosis performance and most previously developed methods ignore the necessity of EEG selection for classification. To this end, this paper proposes a novel maximum weight clique-based EEG selection approach, named mwcEEGs, to map EEG selection to searching maximum similarity-weighted cliques from an improved Fréchet distance-weighted undirected EEG graph simultaneously considering edge weights and vertex weights. Our mwcEEGs improves the classification performance by selecting intra-clique pairwise similar and inter-clique discriminative EEGs with similarity threshold $δ$. Experimental results demonstrate the algorithm effectiveness compared with the state-of-the-art time series selection algorithms on real-world EEG datasets.
