HEMI:超边缘多数影响力最大化

HEMI: Hyperedge Majority Influence Maximization

Varun Gangal, Balaraman Ravindran, Ramasuri Narayanam

摘要:

本文研究了超图上的影响力最大化问题。我们首先将独立级联(IC)模型推广到超图,证明了传统的影响力最大化问题仍然是次模问题。然后,我们提出了一个变种的影响力最大化问题(HEMI),其中一个寻求最大限度地提高超边的数量,其大多数节点的影响。我们证明了在所提出的扩散模型下HEMI是非次模的。

英文摘要:

In this work, we consider the problem of influence maximization on a hypergraph. We first extend the Independent Cascade (IC) model to hypergraphs, and prove that the traditional influence maximization problem remains submodular. We then present a variant of the influence maximization problem (HEMI) where one seeks to maximize the number of hyperedges, a majority of whose nodes are influenced. We prove that HEMI is non-submodular under the diffusion model proposed.
