Next, we compared the DNN-DRT model against the DRTtools for 𝑁 = 𝑀. Both led to similar results for the DRT recovery of the fractal model (𝜀 , = 73.94% and 73.69% for the DNN-DRT and DRTtools, respectively, see Table ), and for the impedance recovery of the PWC (𝜀̅ , = 4.17% and 4.16%) and Gerischer (𝜀̅ , = 4.14% and 4.03%) models (see Figure
