    Analysing Local Sparseness in the Macaque Brain Network. by Raghavendra Singh, Seema Nagar, Amit A Nanavati

    Published 2015-01-01
    “…We propose a novel metric to measure the topological communication load on a vertex due to its immediate neighbourhood, and show that in terms of distribution of this local communication load, a network of Macaque long distance pathways is substantially different from other real world networks and random graph models. Macaque network contains the entire range of local subnetworks, from star-like networks to clique-like networks, while other networks tend to contain a relatively small range of subnetworks. …”

    A Useful Criterion on Studying Consistent Estimation in Community Detection by Huan Qing

    Published 2022-08-01
    “…We summarize the idea of using a separation condition for a standard network and sharp threshold of the Erdös–Rényi random graph to study consistent estimation, and compare theoretical error rates and requirements on the network sparsity of spectral methods under models that can degenerate to a stochastic block model as a four-step criterion SCSTC. …”
