Predicted distributions of six output quantities from the MDN trained on mass and radius inputs only versus the actual values obtained from the interior models for the testing data set: water radial fraction, mantel radial fraction, core radial fraction, core mass fraction, as well as pressure and temperature at the core-mantle-boundary (CMB). Blue dashed diagonal lines denote a perfect performance of the MDN. The predicted distributions are colored according to the local probability density (the color scale is black at the maximum).
