带约束的多凸规划

Disciplined Multi-Convex Programming

Xinyue Shen, Steven Diamond, Madeleine Udell, Yuantao Gu, Stephen Boyd

摘要:

多凸优化问题是指当其他变量固定时,变量可以划分为若干个集合,在这些集合上问题是凸的。多凸问题通常使用交替或循环最小化的变化近似地解决。多凸问题出现在许多应用中,例如非负矩阵分解、广义低秩模型和结构控制综合等。在大多数应用中,迄今为止的多凸性是简单的手工验证。本文利用规则凸规划的思想研究了多凸性的自动检测与验证。我们描述了我们所提出的方法,检测和验证多凸性的实现,然后调用一般的解决方案的方法之一。

英文摘要:

A multi-convex optimization problem is one in which the variables can be partitioned into sets over which the problem is convex when the other variables are fixed. Multi-convex problems are generally solved approximately using variations on alternating or cyclic minimization. Multi-convex problems arise in many applications, such as nonnegative matrix factorization, generalized low rank models, and structured control synthesis, to name just a few. In most applications to date the multi-convexity is simple to verify by hand. In this paper we study the automatic detection and verification of multi-convexity using the ideas of disciplined convex programming. We describe an implementation of our proposed method that detects and verifies multi-convexity, and then invokes one of the general solution methods.
