Multi-model comparisons of the residual error $\Vert {ϵ}_L{(t)\Vert }_{\text{F}}$ for solving high-dimensional matrix LR factorization with different noises. (a) With noiseless. (b) With constant noise ${\rho }_c(t)={[10]}^{4\times 4}$. (c) With period noise ${\rho }_p(t)={[10]}^{4\times 4}\times \text{sin}(2t)$. (d) With random noise ${\rho }_r(t)\in {[8,12]}^{4\times 4}$.
