Total number of galaxies in the training sample (TNG-train) and testing sample (TNG-test, Horizon-AGN, and HSC).

| Horizon-AGN | 196 835 | 80 687(41%) | 116 148 (59%) | 62 096 (32%) | 17 597 (9%) | 36 455 (18%) | – |

Notes. We show how many galaxies in each sample are mergers (and more specifically pre-, ongoing-, and post-mergers, as determined from the merger trees) and non-mergers. For the HSC sample, we show the total number of galaxies along with galaxies that were visually classified as merger, non-merger, and disturbed or minor-mergers, as described in Sect. 3.3.
