WebI will answer my own question, after stumbling upon Squartini and Garlaschelli 2011 article "Analytical maximum-likelihood method to detect patterns in real networks", in ArXiv. Yes, the expected probability of a link between two nodes in a binary graph, as calculated in the classic Modularity score, includes self-loops, and yes this is not ideal. Web17 mrt. 2016 · We typically say that a graph is sparse whenever E ∈ O ( V ) - i.e there are few enough edges. Similarly, we say that a graph is dense whenever E ∈ Θ ( V 2) - i.e there are many edges in your graph. These are not really rules, but rather just the terminology one often uses in textbooks. tesla prices by year

"WebFor example the first of these two graphs is more modular than the second: o===o-----o====o o----o===o-----o. It would be possible to choose a clustering algorithm, run it, and compute your preferred modularity metric for the best clustering found. But this is only a lower bound, so it doesn't seem very satisfactory. The question matters. " - Modularity of a graph
