"Nettetleidenalg. This package implements the Leiden algorithm in C++ and exposes it to python.It relies on (python-)igraph for it to function. Besides the relative flexibility of the implementation, it also scales well, and can be run on graphs of millions of nodes (as long as they can fit in memory). " - Leiden graph-clustering

NettetThe procedure of clustering on a Graph can be generalized as 3 main steps: 1) Build a kNN graph from the data 2) Prune spurious connections from kNN graph (optional step). This is a SNN graph. 3) Find groups of cells that maximizes the connections within the group compared other groups.
