Same diagrams as Fig. 5, with the KDE contours of the AGN (orange), SF (green), and Other (blue) distributions, with the predictions of the RF classifier (see Sect. 4.4) for the clusters derived from the ch3-all cubes of the galaxies from the testing sample: NGC 3227 (circles), NGC 4051 (squares), and NGC 7582 (triangles). We indicate the cluster number in each case (see the clustering maps in Fig. 7).
