and 𝜀̅ , = 8.38% for the deep-DRT model), see Table . In other words, the new DNN architecture proposed herein enabled us to improve the DRT and impedance recoveries, which we confirmed with ten synthetic spectra (Tables and). . The left panel of Figure shows for 𝑁 = 10 𝑀 and each 2×ZARC model the exact, pretrained DNN, and trained DNN DRTs.
