如果恶意攻击者以团伙的方式尝试获取利益,比如骗贷、骗保、薅羊毛,通常都会给对应的公司带来不小的经济损失。团伙识别有各种各样的方法,其中最主要的方法就是“社区发现”(community detection)类算法,常规的方法有 Louvain,Label Propagation,Infomap 等等。 算法核心思想 社区发现类算法似乎并不存在一个最好的算法,因为...

参考:Source code for multilevel community detection with Infomap 该聚类方法刚好可以顺着词向量做一些词间发现,相比Kmeans之类的效果确实好不少。相比其他network 方法(Louvain)实验结果也要好一些,来看一下对比: 速度:运行时长 精确度:精度以输出群集和参考群集之间的标准化互信息(NMI)进行衡量。基准网络由5000个...
