Many research works are in progress in classification of the eye movements using the electrooculography signals and employing them to control the human-computer interface systems. This article introduces a new model for recognizing various eye movements using electrooculography signals with the help of empirical mean curve decomposition and multiwavelet transformation. Furthermore, this article also adopts a principal component analysis algorithm to reduce the dimension of electrooculography signals. Accordingly, the dimensionally reduced decomposed signal is provided to the neural network classifier for classifying the electrooculography signals, along with this, the weight of the neural network is fine-tuned with the assistance of the Levenberg-Marquardt algorithm. Finally, the proposed method is compared with the existing methods and it is observed that the proposed methodology gives the better performance in correspondence with accuracy, sensitivity, specificity, precision, false positive rate, false negative rate, negative predictive value, false discovery rate, F score, and Mathews correlation coefficient.
许多研究工作正在进行中,通过使用眼电图信号对眼球运动进行分类,并将其应用于控制人机交互系统。本文介绍了一种新的模型,通过经验均值曲线分解和多小波变换,利用眼电图信号识别各种眼球运动。此外,本文还采用主成分分析算法来降低眼电图信号的维度。因此,降维分解后的信号被提供给神经网络分类器进行分类,同时,利用列文伯格-马夸尔特算法对神经网络的权重进行微调。最后,将提出的方法与现有的方法进行比较,结果表明,所提出的方法在准确性、灵敏度、特异性、精度、假阳性率、假阴性率、阴性预测值、错误发现率、F 分数和马修斯相关系数等方面都具有更好的性能。
