Reducing Search Space with Louvain

You've learned how LouvainiFull definition for Louvain algorithm (opens in a new tab)A community detection algorithm that repeatedly merges nodes into groups for as long as merging raises modularity. finds communities by optimizing modularityiFull definition for modularity (opens in a new tab)A score for how much more densely connected the nodes within a group are than they would be by chance..

Now let's put it to work. You'll project the fraud network, run Louvain, and see how it reduces your search space by 98%.
