We assessed the cluster membership recovery by computing the Adjusted Rand Index (ARI; Hubert & Arabie, 1985) between the true and estimated partition matrices. The ARI has a maximal value of 1 in case of perfect agreement; a value of 0 indicates that the partition matrices do not correspond...
Uncertain data are common due to the increasing usage of sensors, radio frequency identification (RFID), GPS and similar devices for data collection. The c

首先因为是k个分类 rand(1,k)，产生一行k列随机数 为了找出k个初始列，将0到1，扩展到0到n n*rand(1,k)最后由于你取列那肯定是要整数吧，所以 ceil（n*rand(1,k)）向上取整。也就是说，你 ind 产生的是n个类中选k个作为初始分类种子 对这句话解释的非常详细了吧 ...
:假设函数rand_k会随机返回一个[1, k]之间的随机数(k>=2 ),并且每个证书岀现的概率 相等。目前有rand_7,通过调用rand_7 ()和四则运算符,并适
