VB-Regular-Demon
- 这是一个利用正则表达式来提取指定数据的VB程序演示,利用正则可以很方便地从一堆杂乱的数据中提取所要的数据,示例中提取的是手机号码,还可以对处理结果进行去除重复的处理,大大加快工作的效率。-This is a use regular expressions to extract VB program demonstrates the specified data, the use of regularization can easily extract the desired data a ju
delete-outliers
- 用于去除一个数据集中的野点的matlab函数,可应用数据建模及统计分析-For input vector A, returns a vector B with outliers (at the significance level alpha) removed. Also, optional output argument idx returns the indices in A of outlier values. Optional output argument outlie
SVD.m
- 利用SVD实现item-based CF: 优点: 简化数据,去除噪声,提高算法的结果 缺点: 数据的转换可能难以理解 适用数据类型: 数值型数据(Svd decomposition plays an important role in the decomposition of eigenvalues of high-dimensional data, while using low-dimensional data for approximate approximation)
