- Abstract: We consider the community recovery problem on a multilayer variant of the
hypergraph stochastic block model (HSBM). Each layer is associated with an
independent realization of a d-uniform HSBM on N vertices. Given the similarity
matrix containing the aggregated number of hyperedges incident to each pair of
vertices, the goal is to obtain a partition of the N vertices into disjoint
communities. In this work, we investigate a semidefinite programming (SDP)
approach and obtain information-theoretic conditions on the model parameters
that guarantee exact recovery both in the assortative and the disassortative
cases.

We establish, for the first time in the literature, a sharp threshold for exact recovery under this non-uniform case, subject to minor constraints.
We provide two efficient algorithms which successfully achieve exact recovery when above the threshold, and attain the lowest possible ratio when the exact recovery is impossible.

We consider the community detection problem in random hypergraphs under the nonuniform hypergraph block model (HSBM)
We provide a spectral algorithm that outputs a partition with at least a $gamma$ fraction of the vertices classified correctly, where $gammain depends on the signal-to-noise ratio (SNR) of the model.
The theoretical analysis of our algorithm relies on the concentration and regularization of the adjacency matrix for non-uniform random hypergraphs, which can be of independent interest.

We propose a novel method to co-cluster the vertices and hyperedges of hypergraphs with edge-dependent weights (EDVWs)
In our method, we leverage random walks with EDVWs to construct a hypergraph Laplacian and use its spectral properties to embed vertices and hyperedges in a common space.
We then cluster these embeddings to obtain our proposed co-clustering method, of particular relevance in applications requiring the simultaneous clustering of data entities and features.
