Abstract

Brain status information is captured by physiological electroencephalogram (EEG) signals, which are extensively used to study different brain activities. This study investigates the use of a new ensemble classifier to detect an epileptic seizure from compressed and noisy EEG signals. This noise-aware signal combination (NSC) ensemble classifier combines four classification models based on their individual performance. The main objective of the proposed classifier is to enhance the classification accuracy in the presence of noisy and incomplete information while preserving a reasonable amount of complexity. The experimental results show the effectiveness of the NSC technique, which yields higher accuracies of 90% for noiseless data compared with 85%, 85.9%, and 89.5% in other experiments. The accuracy for the proposed method is 80% when SNR=1 dB, 84% when SNR=5 dB, and 88% when SNR=10 dB, while the compression ratio (CR) is 85.35% for all of the datasets mentioned.

摘要

大脑状态信息由生理脑电图(EEG)信号捕获,这些信号被广泛用于研究不同的大脑活动。本研究调查了一种新型集成分类器用于从压缩且有噪声的EEG信号中检测癫痫发作的情况。这种噪声感知信号组合(NSC)集成分类器根据四个分类模型各自的性能对它们进行组合。所提出的分类器的主要目标是在存在噪声和不完整信息的情况下提高分类准确率,同时保持合理的复杂度。实验结果表明了NSC技术的有效性,对于无噪声数据,该技术的准确率高达90%,而其他实验的准确率分别为85%、85.9%和89.5%。当信噪比(SNR)=1 dB时,所提方法的准确率为80%;当SNR=5 dB时,准确率为84%;当SNR=10 dB时,准确率为88%,而上述所有数据集的压缩率(CR)均为85.35%。
