斐波那契数列(Fibonacci sequence),又称黄金分割数列,因意大利数学家莱昂纳多·斐波那契(Leonardo Fibonacci)以兔子繁殖为例子而引入,故又称为“兔子数列”。 斐波那契数列指的是这样一个数列:1,1,2,3,5,8,13,21,34,55,89..,这个数列从第3项开始,每一项都等于前两项之和。
Nonparametric bagging clustering methods are studied and compared to identify latent structures from a sequence of dependent categorical data observed along a one-dimensional (discrete) time domain. The frequency of the observed categories is assumed to be generated by a (slowly varying) latent signal...
