摘要:

研究了高阶种植模型生成的超图的有效精确划分问题。高阶种植模型假设一些底层的集群结构,并通过在节点之间放置超边来模拟高阶交互。示例模型包括不相交的超团,dennial子超图和超图随机块模型。我们证明了高阶种植模型的精确划分(一般来说是NP难问题)是通过求解具有张量核范数约束的计算效率高的凸优化问题来实现的。我们的分析为我们的方法成功地恢复真正的底层集群结构提供了条件,具有很高的概率。

英文摘要:

We study the problem of efficient exact partitioning of the hypergraphs generated by high-order planted models. A high-order planted model assumes some underlying cluster structures, and simulates high-order interactions by placing hyperedges among nodes. Example models include the disjoint hypercliques, the densest subhypergraphs, and the hypergraph stochastic block models. We show that exact partitioning of high-order planted models (a NP-hard problem in general) is achievable through solving a computationally efficient convex optimization problem with a tensor nuclear norm constraint. Our analysis provides the conditions for our approach to succeed on recovering the true underlying cluster structures, with high probability.
