This paper investigates fundamental limits of exact recovery in the general
d-uniform hypergraph stochastic block model (d-HSBM), wherein n nodes are
partitioned into k disjoint communities with relative sizes (p1,..., pk). Each
subset of nodes with cardinality d is generated independently as an order-d
hyperedge with a certain probability that depends on the ground-truth
communities that the d nodes belong to. The goal is to exactly recover the k
hidden communities based on the observed hypergraph. We show that there …
