DETERMINING TRUNCATION PARAMETER IN SVD
Institute of Science, Information Engineering University, Zhengzhou 450001
Abstract On the basis of Singular Value Decomposition (SVD) theory and analyzing TSVD method, a new technique for amending singular values based on the multicollineary diagnosis is proposed. The numerical results show that the proposed method can resist the illconditioned effect and improve the stability and accuracy of parameter estimation.
Key words :
