查询词典 data mining

Uniform random sampling is widely applied to many kinds of algorithms in data mining. It processes uniform distribution data set extremely effectively, but easily loses slight cluster and consequently decreases clustering accuracy, when the processing data set is skew distribution.

随机抽样技术已经广泛应用于数据挖掘的各类算法中，它在处理分布均匀的数据集时非常有效，但在处理分布比较倾斜的数据集时容易丢失小的聚类。
