[Other resourceK-均值聚类算法C++编程

Description: K-均值聚类算法的编程实现。包括逐点聚类和批处理聚类。K-均值聚类的的时间复杂度是n*k*m,其中n为样本数,k为类别数,m为样本维数。这个时间复杂度是相当客观的。因为如果用每秒10亿次的计算机对50个样本采用穷举法分两类,寻找最优,列举一遍约66.7天,分成3类,则要约3500万年。针对算法局部最优的缺点,本人正在编制模拟退火程序进行改进。希望及早奉给大家,倾听高手教诲。-K-means clustering algorithm programming. Point by point, including clustering and clustering batch. K-means clustering of the time complexity of n * k * m, n samples, several types of k, m sample dimension. The time complexity is a very objective. Because if we use one billion times per second the computer using 50 samples of two exhaustive method to find the optimal set out again about 66.7 days, divided into three categories, offering 3,500 years. Local optimal algorithm against the shortcomings, I was prepared simulated annealing process improvements. Early Feng hope for everyone, listen to the master teachings.

[Crack Hack简易的矩陣加密編编码法

Description: 算法介绍 矩阵求逆在程序中很常见,主要应用于求Billboard矩阵。按照定义的计算方法乘法运算,严重影响了性能。在需要大量Billboard矩阵运算时,矩阵求逆的优化能极大提高性能。这里要介绍的矩阵求逆算法称为全选主元高斯-约旦法。 高斯-约旦法(全选主元)求逆的步骤如下: 首先,对于 k 从 0 到 n - 1 作如下几步: 从第 k 行、第 k 列开始的右下角子阵中选取绝对值最大的元素,并记住次元素所在的行号和列号,在通过行交换和列交换将它交换到主元素位置上。这一步称为全选主元。 m(k, k) = 1 / m(k, k) m(k, j) = m(k, j) * m(k, k),j = 0, 1, ..., n-1;j != k m(i, j) = m(i, j) - m(i, k) * m(k, j),i, j = 0, 1, ..., n-1;i, j != k m(i, k) = -m(i, k) * m(k, k),i = 0, 1, ..., n-1;i != k 最后,根据在全选主元过程中所记录的行、列交换的信息进行恢复,恢复的原则如下:在全选主元过程中,先交换的行(列)后进行恢复;原来的行(列)交换用列(行)交换来恢复。-algorithm introduced in the matrix inversion process is very common, which are mainly used for Billboard matrix. In accordance with the definition of the method of calculating multiplication, seriously affecting the performance. The need for a large number of Billboard matrix operations, matrix inversion optimization can significantly improve performance. Here we introduce the matrix inversion algorithm called full-elected PCA Gauss-Jordan and France. Gauss-Jordan and France (all elected PCA) inversion of the following steps : First, for k from 0 to n-1 for the following steps : from the first trip k, k started out the bottom right corner Subarray largest absolute selected elements, and element remember meeting the line and out, the adoption OK exchange and the exchange out of its exchange
