Confusion of cluster classifications for a multi-planet population with N-body interactions. Same as Fig. 6, but computed for a population with 100 planets per disk that interact gravitationally. Clusters 2 (icy cores) and 3 (giant planets) are predicted most reliably. Due to giant collisions the classifier cannot predict, the super-Earths in cluster 4 are often mistaken for (sub-)Neptunes (cluster 1).
