If you took part in the Kaggle survey about data science, you might be stumpled upon the Data Skeptic Podcast. It’s one of my favourite data science podcast.
They did a great episode about the louvain distance for community detection. Basically it’s a mathematical way of weighing the interconnectedness of a connected graph.
So the cool thing about this podcast episode, there is a beautiful implementation by another Blogger named Eliot Andres. He created an amazing Tutorial/Jupyter Notebook to calculate the louvain distance for facebook friends.
