基于云模型的花片特征提取算法，该算法通过云模型的逆向正态云发生器，由样本点信息，求解出三类花四个特征参数各自的数字特征：期望、熵、超熵。-Based on Cloud Model Motif feature extraction algorithm, which cloud model of reverse normal cloud generator, the sample point information, solving the three spent four the number o

复杂网络中，对无向图基于不同的motif将无向图进行分类，原里是选择具有最小的电导率的cluster作为一类- SPECTRALPARTITIONING performs a spectral partitioning of A and returns several relevant quantities. It assumes that A is undirected and connected.
