非负矩阵分解的凸算法

Convex Algorithms for Nonnegative Matrix Factorization

Vijay Krishnamurthy, Alexandre d'Aspremont

摘要:

本文给出了非负矩阵分解问题的近似算法,即把一个矩阵分解为两个非负系数矩阵的乘积的问题。我们形成凸近似这个问题,可以有效地解决和测试我们的算法上的一些经典的数值例子。

英文摘要:

We derive approximation algorithms for the nonnegative matrix factorization problem, i.e. the problem of factorizing a matrix as the product of two matrices with nonnegative coefficients. We form convex approximations of this problem which can be solved efficiently and test our algorithms on some classic numerical examples.
