Our model assumes that layers belonging to a stratum have community structure following the same underlying SBM. To fit sMLSBM to a multilayer network, and more-specifically, a multiplex network, we iteratively alternate between rearranging layer-tostrata assignments and updating the model parameters for each stratum. ...

First, we find the complete probabilistic solution to the problem of finding the optimal multilayer SBM for a given aggregate-observed network. Because this solution is computationally intractable, we propose an approximation that enables us to verify that multilayer SBMs are more predictive of network structure in real-world complex systems.

The parameter MLE $hat{theta}_i$ in our TDD-SBM for directed, multilayer networks is analogous to the MLE of a degree-correction parameter in a degree-corrected SBM for undirected networks with one layer (Karrer and Newman Reference Karrer and Newman 2011). Indeed, the MLE for the degree-correction parameter of a node in the latter model …

communities in multilayer networks, we consider the stochastic block model (SBM) [22], a popular generative model for community structure in networks. The assumption of the SBM is that nodes in a particular community are related to nodes within and between communities in the same way, thus allowing SBMs to describe several types of …
