Network Goodness-of-Fit for the block-model family
Jiashun Jin, Zheng Tracy Ke, Jiajun Tang +1
The block-model family has four popular network models (SBM, DCBM, MMSBM, and DCMM). A fundamental problem is, how well each of these models fits with real networks. We propose GoF…
Power Enhancement and Phase Transitions for Global Testing of the Mixed Membership Stochastic Block Model
Louis Cammarata, Zheng Tracy Ke
The mixed-membership stochastic block model (MMSBM) is a common model for social networks. Given an -node symmetric network generated from a -community MMSBM, we would like t…
Optimal Adaptivity of Signed-Polygon Statistics for Network Testing
Jiashun Jin, Zheng Tracy Ke, Shengming Luo
Given a symmetric social network, we are interested in testing whether it has only one community or multiple communities. The desired tests should (a) accommodate severe degree het…
A Sharp Lower Bound for Mixed-membership Estimation
Jiashun Jin, Zheng Tracy Ke
Consider an undirected network with nodes and perceivable communities, where some nodes may have mixed memberships. We assume that for each node , there is…
