一种用于序列特征提取的邻近点法

A proximal point algorithm for sequential feature extraction applications

Xuan Vinh Doan, Kim-Chuan Toh, Stephen Vavasis

摘要:

提出了一种解决LAROS问题的邻近点法,即寻找“大的近似秩一子矩阵”的问题。这个LAROS问题用于顺序地提取数据中的特征。基于LAROS问题的\eps -最优解的对偶性条件,提出了一种新的邻近点法的停止准则,并给出了理论保证.我们测试我们的算法与两个图像数据库,并表明,我们可以使用LAROS问题,从这些图像中提取适当的共同特征。

英文摘要:

We propose a proximal point algorithm to solve LAROS problem, that is the problem of finding a "large approximately rank-one submatrix". This LAROS problem is used to sequentially extract features in data. We also develop a new stopping criterion for the proximal point algorithm, which is based on the duality conditions of \eps-optimal solutions of the LAROS problem, with a theoretical guarantee. We test our algorithm with two image databases and show that we can use the LAROS problem to extract appropriate common features from these images.
