Intelligent computing tools such as artificial neural network (ANN) and fuzzy logic approaches are demonstrated to be competent when applied individually to a variety of problems. Recently, there has been a growing interest in combining both these approaches, and as a result, neuro-fuzzy computing techniques have been evolved. In this study, a new approach based on an adaptive neuro-fuzzy inference system (ANFIS) was presented for epileptic seizure detection. The proposed ANFIS model combined the neural network adaptive capabilities and the fuzzy logic qualitative approach. Decision making was performed in two stages: feature extraction using the wavelet transform (WT) and the ANFIS trained with the backpropagation gradient descent method in combination with the least squares method. Some conclusions concerning the impacts of features on the detection of epileptic seizures were obtained through analysis of the ANFIS. The results are highly promising, and a comparative analysis suggests that the proposed modeling approach outperforms ANN model in terms of training performances and classification accuracies. The results confirmed that the proposed ANFIS model has some potential in epileptic seizure detection. The ANFIS model achieved accuracy rates which were higher than that of the stand-alone neural network model.
诸如人工神经网络(ANN)和模糊逻辑方法等智能计算工具在单独应用于各种问题时已被证明是有效的。最近,将这两种方法结合起来的兴趣日益浓厚,因此,神经模糊计算技术应运而生。在本研究中,提出了一种基于自适应神经模糊推理系统(ANFIS)的癫痫发作检测新方法。所提出的ANFIS模型结合了神经网络的自适应能力和模糊逻辑的定性方法。决策分两个阶段进行:使用小波变换(WT)进行特征提取,以及使用反向传播梯度下降法结合最小二乘法训练的ANFIS。通过对ANFIS的分析,得出了一些关于特征对癫痫发作检测影响的结论。结果很有前景,对比分析表明,所提出的建模方法在训练性能和分类准确率方面优于ANN模型。结果证实,所提出的ANFIS模型在癫痫发作检测方面具有一定潜力。ANFIS模型实现的准确率高于独立神经网络模型。
