- W2367432783 abstract "Principal components analysis(PCA) for high-dimensional data is a difficult problem because the computational time and the space complexity rapidly increase as the data dimensions increase.A data-oriented and covariance-free PCA algorithm is proposed,inspired by the idea that the updated eigenvector in iteration is the weighted average of all samples.In a stationary environment or the condition that all training samples are available,the proposed algorithm is capable of overcoming the shortage of the conventional batch or incremental approaches.Furthermore,the convergence of the proposed algorithm is proved mathematically.Experimental results show that the most accurate solution is converged in a few iterations by the proposed algorithm." @default.
