将数据集转换为拉普拉斯矩阵，然后利用基于图论的谱聚类进行聚类。拉普拉斯矩阵采用高斯核函数，全连接方法计算。谱聚类擅长处理高维数据或非凸数据集。(The data set is transformed into Laplacian matrix, and then clustered by spectral clustering based on graph theory. The Laplacian matrix is calculated by using the Gauss kernel function and the full connection method. Spectral clustering is good at dealing with high-dimensional or non-convex data sets.)

数据挖掘经典算法，频繁项集挖掘经典算法，CFPGROWTH算法，JAVA实现，代码中有详细注释

三次样条插值的C语言算法,但是总是数据溢出()

weka是一个很优秀的数据挖掘软件，可以把weka作为程序包打入工程中，基本想要的功能很快就能实现

用于数据自编码，非线性压缩，降维的一种方法；与PCA不同，pca为线性降维方式(Data auto encoding, nonlinear compression)

分而治之方法与软件设计的模块化方法非常相似,为了解决一个大的问题,可以： 1) 把它分成两个或多个更小的问题； 2) 分别(The divide-and-conquer approach is very similar to the modular approach to software design. To solve a big problem, you can: 1) divide it into two or more smaller problems; 2))

说明：  粗糙集在进行属性约简时需要求其正域，此为求正域程序(Rough Set for Positive Domain)

ap算法完成ap聚类操作 需要输入参数为数据集 偏向参数 输出结果为聚类数目(The AP algorithm completes the AP clustering operation, the input parameter is the data set bias parameter, and the output result is the number of clusters)
