Relation between disk features and planet species. Upper panel: mean decision boundaries of the classifier, indicating the importance of each feature and its preferred magnitude for the different clusters. The starting location of the planet embryo a_start shows the largest variance in decision boundary. Giant planets (yellow) are also very sensitive on M_solid,0 and somewhat sensitive on M_gas,0. Lower panels: relationship of the input features with planet mass. The starting location of the planet embryo a_start shows the strongest correlation with cluster affiliation and planet mass.
