Description of the training, validation, test, and SNEMO15-only test set used in this work.
| Training set | 50% light curves from theoretical |
| SN Ia models | |
| + | |
| 50% light curves from SNEMO15-T | |
| Validation set | 50% light curves from theoretical |
| SN Ia models | |
| + | |
| 50% light curves from SNEMO15-V | |
| Test set | 50% light curves from theoretical |
| SN Ia models | |
| + | |
| 50% light curves from SNEMO15-E | |
| SNEMO15-only test set | 100% light curves from SNEMO15-E |
Notes. The SNEMO15 light curves are split randomly into three distinct subsets with no overlap in light curves: SNEMO15-T for training, SNEMO15-V for validation and SNEMO15-E for testing. This ensures that light curves used in one process (e.g., validation) are not used in another process (e.g., training or testing).
