Fig. 6: Atom-normalized volume model.
From: Machine learning assisted prediction of organic salt structure properties
Heat map showing the performance of the volume model on the 'testing set', with results from the testing set averaged over all 10 fitting-validation iterations. Data shown corresponds to Fig. 5a with volumes normalized per atom in the unit cell. Colors toward the red end of the color spectrum indicate regions of higher densities of data points. Dashed red line guides the eye to show vDFT = vML.
