Neuro-fuzzy system is a combination of neural network and fuzzy system in such a way that neural network learning algorithms, is used to determine parameters of the fuzzy system. This paper describes the application of multiple adaptive neuro-fuzzy inference system (MANFIS) model which has hybrid learning algorithm for classification of hemiplegic gait acceleration (HGA) signals. Decision making was performed in two stages: feature extraction using the wavelet transforms (WT) and the ANFIS trained with the backpropagation gradient descent method in combination with the least squares method. The performance of the ANFIS model was evaluated in terms of training performance and classification accuracies and the results confirmed that the proposed ANFIS model has potential in classifying the HGA signals.
神经模糊系统是神经网络和模糊系统的一种组合,其方式是利用神经网络学习算法来确定模糊系统的参数。本文描述了具有混合学习算法的多重自适应神经模糊推理系统(MANFIS)模型在偏瘫步态加速度(HGA)信号分类中的应用。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和最小二乘法相结合训练的自适应神经模糊推理系统(ANFIS)。通过训练性能和分类准确率对ANFIS模型的性能进行了评估,结果证实所提出的ANFIS模型在对HGA信号进行分类方面具有潜力。
