中文说明：
RBF（径向基神经网络）网络是一种重要的神经网络，RBF网络的训练分为两步，第一步是通过聚类算法得到初始的权值，第二步是根据训练数据训练网络的权值
English Description：
RBF (radial basis function neural network) network is an important neural network. The training of RBF network is divided into two steps. The first step is to obtain the initial weight through clustering algorithm, and the second step is to train the weight of the network according to the training data
