A New Feature Extraction Algorithm Based on Orthogonal Regularized Kernel CCA and Its Application

الملخص EN

In this paper, an orthogonal regularized kernel canonical correlation analysis algorithm (ORKCCA) is proposed.

ORCCA algorithm can deal with the linear relationships between two groups of random variables.

But if the linear relationships between two groups of random variables do not exist, the performance of ORCCA algorithm will not work well.

Linear orthogonal regularized CCA algorithm is extended to nonlinear space by introducing the kernel method into CCA.

Simulation experimental results on both artificial and handwritten numerals databases show that the proposed method outperforms ORCCA for the nonlinear problems.
