EEG is the most common test for diagnosing a seizure, where it presents information about the electrical activity of the brain. Automatic Seizure detection is one of the challenging tasks due to limitations of conventional methods with regard to inefficient feature selection, increased computational complexity and time and less accuracy. The situation calls for a practical framework to achieve better performance for detecting the seizure effectively. Hence, this study proposes modified Blackman bandpass filter-greedy particle swarm optimization (MBBF-GPSO) with convolutional neural network (CNN) for effective seizure detection. In this case, unwanted signals (noise) is eliminated by MBBF as it possess better ability in stopband attenuation, and, only the optimized features are selected using GPSO. For enhancing the efficacy of obtaining optimal solutions in GPSO, the time and frequency domain is extracted to complement it. Through this process, an optimized features are attained by MBBF-GPSO. Then, the CNN layer is employed for obtaining the productive classification output using the objective function. Here, CNN is employed due to its ability in automatically learning distinct features for individual class. Such advantages of the proposed system have made it explore better performance in seizure detection that is confirmed through performance and comparative analysis.
脑电图(EEG)是诊断癫痫发作最常用的测试方法,它能呈现有关大脑电活动的信息。由于传统方法在特征选择效率低下、计算复杂度增加、耗时且准确性较低等方面存在局限性,自动癫痫发作检测是一项具有挑战性的任务之一。这种情况需要一个实用的框架来实现更好的性能,以有效地检测癫痫发作。因此,本研究提出了改进的布莱克曼带通滤波器 - 贪婪粒子群优化算法(MBBF - GPSO)与卷积神经网络(CNN)相结合的方法用于有效的癫痫发作检测。在这种情况下,MBBF能够消除不需要的信号(噪声),因为它在阻带衰减方面具有更好的能力,并且仅使用GPSO选择优化后的特征。为了提高GPSO中获得最优解的效率,提取时域和频域信息对其进行补充。通过这个过程,MBBF - GPSO获得了优化后的特征。然后,利用CNN层通过目标函数获得有效的分类输出。在此,采用CNN是因为它能够自动为每个类别学习独特的特征。所提出系统的这些优势使其在癫痫发作检测中表现出更好的性能,这通过性能和对比分析得到了证实。
