我们提出了一种半确定规划(SDP)方法,用于存在额外非图形侧信息的图中的社区检测,并分析了相应的精确恢复阈值。社区检测问题是在二进制对称随机块模型(SBM)的背景下考虑的,侧信息以部分显示的标签的形式存在,其擦除概率为λ。结果表明,极大似然估计器的半定规划松弛可以精确地恢复到最优阈值。通过有限合成数据集的仿真验证了本文的理论发现,表明本文的渐近结果也可以解释有限n下的性能。
We propose a semidefinite programming (SDP) approach to community detection in graphs in the presence of additional non-graphical side information, and analyze the corresponding exact recovery threshold. The community detection problem is considered in the context of the binary symmetric Stochastic Block Model (SBM), and the side information is in the form of partially revealed labels with erasure probability ϵ. Our results show that the semidefinite programming relaxation of the maximum likelihood estimator can achieve exact recovery down to the optimal threshold. The theoretical findings of this paper are validated via simulations on finite synthetic data-sets, showing that the asymptotic results of this paper can also shed light on the performance at finite n.
