WebAug 1, 2024 · 这个算法在 NetworkX 库中被称为 "greedy_modularity_communities",它是用于求社区结构的一种算法,基于 Modularity 原理。 Modularity 是社区发现中的一种常用指标,用于衡量网络的社区结构的优良程度。其中,"greedy_modularity_communities" 是使用贪心算法来最大化 Modularity 指标。 WebJan 26, 2024 · It looks like, in calculate_community_modularity, you use greedy_modularity_communities to create a dict, modularity_dict, which maps a node in your graph to a community. If I understand correctly, you can take each subgraph community in modularity_dict and pass it into shannon_entropy to calculate the entropy …

WebApr 27, 2015 · A precise definition of the modularity from wikipedia: Modularity is the fraction of the edges that fall within the given groups minus the expected such fraction if edges were distributed at random. The value of the modularity lies in the range [−1/2,1). It is positive if the number of edges within groups exceeds the number expected on the ... WebJul 14, 2024 · 这是Newman (2006)提出的一种自上而下的分层社区发现算法。该算法的核心是定义了一个模块度矩阵(modularity matrix)。最大化模块度的过程可以体现在模块度矩阵的特征值分解中,模块度矩阵在社区发现中的作用类似于由图拉普拉斯算子在图划分中发挥 … hotels near market hall raleigh nc

It must be a positive numeric vector, NULL or NA. If it is NULL and the input graph has a ‘weight’ edge attribute, then that attribute will be used. If NULL and no such attribute is present, then the edges will have equal weights. Set this to NA if the graph was a ‘weight’ edge attribute, but you don't want to ...
