社区发现(Community Detection)通常用于对图进行群组划分,将具有特定关联关系的顶点和关系划分到同一个社区中,在风控反欺诈领域,往往会用来进行恶意团伙识别或不同团伙的定性以识别各种类型的团伙。下文主要简单介绍一下network中提供的一些常用的社区发现算法的实现。列表如下: ...
根据community detection的思路，网络A的community是那些发数据较为频繁的用户集合，网络B中的community是IP...
But I can not get the desired number of communities. Are there some algorithm for this, using Networkx? I'm also new to networkx and igraph, I used Gephi, an data visualization tool/software. And it has the same community detection algorithm as the one in networkx you are now using. Sp...

NetworkX是一个图论和复杂网络的科学网络建模工具,为了方便我们进行分析网络,方针建模等工作,它里面内置了常用的图与复杂网络的分析算法。最近在用来做community detection,下面是一些使用方法我经验介绍,与大家分享。 首先就是安装networkx与Python开发环境,安装很简单,不熟悉的话按照下面的步骤一次安装就行了。
Advanced NetworkX: Community detection with modularity 关于网络数据集的另一个常见问题是,在更大的社会结构中,子组或社区是什么。你的社交网络是一个人人都认识的快乐大家庭吗?或者,它是一组较小的子组,仅由一两个中介连接? 有好多方法,但比较常见的是用modularity来做社区发现。Modularity is a measure of re...

NetworkX还提供多种高级功能，用于对图进行复杂操作。例如，通过`shortest_path()`计算两个节点之间的最短路径，`betweenness_centrality()`评估节点在网络中的重要性，以及`community_detection()`用于识别图中的社区结构等。这些功能为网络分析提供了强大的工具集。

There are many uses of graph network analysis, such as analyzing relationships in social networks, cyber threat detection, and identifying the people most likely to buy a product based on shared preferences. In the real world, nodes can be people, groups, places, or things such as customers,...
