代码说明:

支持向量机(support vector machines, SVM)是一种二分类模型,它的基本模型是定义在特征空间上的间隔最大的线性分类器,间隔最大使它有别于感知机;SVM还包括核技巧,这使它成为实质上的非线性分类器。SVM的的学习策略就是间隔最大化,可形式化为一个求解凸二次规划的问题,也等价于正则化的合页损失函数的最小化问题。SVM的的学习算法就是求解凸二次规划的最优化算法。

    展示了如何生成一个随机无标度网络图,基本结构分析,包括度分布、聚类系数等。观察两种类型的攻击对网络的影响:随机攻击(所有的几点有相同的概率从网络中删除)、有目标地选择连接度最大的节点(节点度最大的节点从网络中删除)。(Shows how to generate a random scale-free network graph, basic structural analysis, including degree distribution, clustering coefficients, etc. Observe the impact of two types of attacks on the network: Random attacks (all points have the same probability of being removed from the network), and select the node with the highest degree of connectivity (the node with the highest node degree is removed from the network).)
