class LabelPropagation extends Arguments

Run static Label Propagation for detecting communities in networks.

Each node in the network is initially assigned to its own community. At every iteration, nodes send their community affiliation to all neighbors and update their state to the mode community affiliation of incoming messages.

LPA is a standard community detection algorithm for graphs. It is very inexpensive computationally, although (1) convergence is not guaranteed and (2) one can end up with trivial solutions (all nodes are identified into a single community).

The resulting DataFrame contains all the original vertex information and one additional column:

    The max number of iterations of LPA to be performed.

    The max number of iterations of LPA to be performed. Because this is a static implementation, the algorithm will run for exactly this many iterations.
