Table 1 Values of SNR and API for jitterless data with N = 3, for various fixed values of λ , as well as for the varying-lambda strategy detailed in the text

From: Separation of phase-locked sources in pseudo-real MEG data

  λ 0.025 0.05 0.1 0.2 0.4
SNR Fixed 17.5 ± 21.2 27.5 ± 18.0 34.4 ± 4.3 27.2 ± 3.6 13.5 ± 5.5
  Varying    48.9 ± 8.7   
API Fixed 0.795 ± 0.570 0.369 ± 0465 0.048 ± 0.057 0.079 ± 0.027 0.327 ± 0.097
  Varying    0.013 ± 0.015   
  1. While the best fixed value, λ = 0.1, yields decent results, the results using a varying value of λ are consistently better, with a large margin.
