Based on our methodology for community detection and community comparison in graphs (Lyzinski et al., 2015, http://arxiv.org/abs/1503.02115), we formulate a model selection procedure for deciding whether a hierarchical stochastic blockmodel graph supports the conjecture of repeated motifs. Such a graph inference procedure promises to address a fundamental outstanding question regarding the atoms of neural computation (Marcus, Marblestone & Dean, 2014, http://arxiv.org/abs/1410.8826)
