神经网络用于分类与回归,先产生训练样本与测试样本，每一列为一个样本( neural network for classification and regression, first create the training samples and test samples, each as a sample of)

K-means is a clustering algorithm In the beginning we determine number of cluster K and we assume the centroid or center of these clusters. We can take any random objects as the initial centroids or the first K objects in sequence can also serve as the initial centroids. There are two function for that the kMeanCluster and distMatrix
