Influence of choice for τ_est on accuracy of recovered C.

A Best estimated matrices C for τ_est = 0, 0.1, 1 and 5 s. For τ_est = 1, the C matrix at the end of the optimization (step 10000) is also shown. B Evolution of Q errors for the optimizations with various τ_est in A. bf C C errors corresponding to the best matrices in A (red solid curve), as well as last matrices of the optimization (red dashed curve). The green curve indicates the error of the best C with the symmetric part of the original C. The blue curve indicates the error between the empirical and the corresponding theoretical matrix. D Pearson correlation coefficient between the best and original C (red) as well as reconstructed and objective Q^0/τ. between and each corresponding theoretical Q^τ matrix for the same τ = τ_est in C. E Comparison between LO with empirical calculated with Eq (2) (red solid curve) and LO with theoretical obtained from Eq (7) (red dashed curve). The blue curve indicates the inaccuracy between the empirical and theoretical Q^τ matrices. F Same as B for the Q error with theoretical objectives .
