On the tractability and approximability of non-submodular cardinality-based - cut problems in hypergraphs

V Bengali, N Veldt - arXiv preprint arXiv:2409.16195, 2024 - arxiv.org
A minimum $ s $-$ t $ cut in a hypergraph is a bipartition of vertices that separates two
nodes $ s $ and $ t $ while minimizing a hypergraph cut function. The cardinality-based …

Revisiting Link Prediction with the Dowker Complex

JW Choi, Y Chen, J Frías, J Castillo, Y Gel - Pacific-Asia Conference on …, 2024 - Springer
We propose a novel method to study properties of graph-structured data by means of a
geometric construction called Dowker complex. We study this simplicial complex through the …
