摘要:

我们提出了一个通用的框架块结构的非凸优化,它可以应用于结构化的子图检测相互依赖的网络,如多层网络,时间网络,网络的网络,和许多其他的。具体来说,我们设计了一个有效的,高效的,可并行化的投影算法,即图块结构梯度投影(GBGP),优化一般的非线性函数的图形结构的约束。我们证明了我们的算法:1)运行在网络规模的近似线性时间; 2)享有理论上的近似保证。此外,我们展示了我们的框架可以应用到两个非常实际的应用程序,并进行全面的实验,以显示我们所提出的算法的有效性和效率。

英文摘要:

We propose a generalized framework for block-structured nonconvex optimization, which can be applied to structured subgraph detection in interdependent networks, such as multi-layer networks, temporal networks, networks of networks, and many others. Specifically, we design an effective, efficient, and parallelizable projection algorithm, namely Graph Block-structured Gradient Projection (GBGP), to optimize a general non-linear function subject to graph-structured constraints. We prove that our algorithm: 1) runs in nearly-linear time on the network size; 2) enjoys a theoretical approximation guarantee. Moreover, we demonstrate how our framework can be applied to two very practical applications and conduct comprehensive experiments to show the effectiveness and efficiency of our proposed algorithm.
