The analysis shows with solid blue circles the CNN-estimated material properties, \(\hat{m}\), versus their real values (ground truth), m, where m represents \({\log }_{10}(K)\), \({\log }_{10}(G)\), ρ, and η. The \(\hat{m}=m\) ground truth line is shown with a solid magenta line. The R2 and SMAPE metrics of each parameter are listed in the lower right corner of each panel.
