Fig. 3.From: Transient feature extraction method based on adaptive TQWT sparse optimization3d curve of adaptive parameter optimization. The figure shows the SAEWSE value in the two-dimensional grid search space of parameter (Q,r); the optimal parameter \((Q_{opt} = 3.1,\;r_{opt} = 3.5)\) is determined according to the minimum value of SAEWSE curveBack to article page
