Fig. 4

Comparison of apparent resistivity of different methods without noise. The first column is the designed resistivity model, the second column is the apparent resistivity calculated by FEM, the third column is the apparent resistivity simulated by T-Unet, and the fourth column is the apparent resistivity simulated by T-Unet. The fifth column shows the relative error distribution of apparent resistivity between FEM and Unet method, which is recorded as RE Unet. The sixth column shows the relative error distribution of apparent resistivity between FEM and T-Unet method, which is recorded as RE T-Unet.
