摘要(Abstract)
We propose an efficient algorithm for solving orthogonal canonical correlation analysis (OCCA) in the form of trace-fractional structure and orthogonal linear projections.
我们提出了一种有效的算法,用于以迹分数结构和正交线性投影的形式求解正交典型相关分析(OCCA)。.
Even though orthogonality has been widely used and proved to be a useful criterion for visualization, pattern recognition and feature extraction, existing methods for solving OCCA problem are either numerically unstable by relying on a deflation scheme, or less efficient by directly using generic optimization methods.
尽管正交性已被广泛应用,并被证明是可视化、模式识别和特征提取的一个有用标准,但现有的OCCA问题求解方法要么依靠通缩方案在数值上不稳定,要么直接使用通用优化方法效率较低。.
In this paper, we propose an alternating numerical scheme whose core is the sub-maximization problem in the trace-fractional form with an orthogonality constraint.
本文提出了一种交替数值格式,其核心是带正交约束的迹分数形式的次最大化问题。.
A customized self-consistent-field (SCF) iteration for this sub-maximization problem is devised.
针对这个次最大化问题,设计了一个定制的自洽场(SCF)迭代。.
It is proved that the SCF iteration is globally convergent to a KKT point and that the alternating numerical scheme always converges.
证明了SCF迭代全局收敛于KKT点,交替数值格式始终收敛。.
We further formulate a new trace-fractional maximization problem for orthogonal multiset CCA and propose an efficient algorithm with an either Jacobi-style or Gauss-Seidel-style updating scheme based on the SCF iteration.
我们进一步建立了一个新的正交多集CCA跟踪分数最大化问题,并提出了一种基于SCF迭代的Jacobi或Gauss-Seidel更新方案。.
Extensive experiments are conducted to evaluate the proposed algorithms against existing methods, including real-world applications of multi-label classification and multi-view feature extraction.
我们进行了大量实验,以评估所提出的算法与现有方法的对比,包括多标签分类和多视图特征提取的实际应用。.
Experimental results show that our methods not only perform competitively to or better than the existing methods but also are more efficient…
实验结果表明,我们的方法不仅在性能上优于现有方法,而且效率更高。。.
