Table C.1.
Accuracy scores (as defined in Sect. 3.3) for the three target galaxy properties (Σ⋆, Z⋆, and t⋆) inferred using the four Euclid surface brightnesses, six colours modelled from them, and six squared colours using a DNN.
| Target | R2 | RMSE | fout | NMAD | ⟨ΔY⟩ | ρ |
|---|---|---|---|---|---|---|
| Σ⋆ / (M⊙ pc−2) | 0.927 | 0.130 | 0.0325 | 0.1088 | 0.0020 | 0.963 |
| Z⋆ | 0.595 | 0.076 | 0.0007 | 0.0719 | 0.0024 | 0.773 |
| t⋆ / Gyr | 0.382 | 0.128 | 0.0281 | 0.0994 | −0.0017 | 0.623 |
Notes. Left to right: Target; coefficient of determination (R2); root-mean-square error (RMSE); fraction of catastrophic outliers (fout); normalised median absolute deviation (NMAD); and bias (⟨ΔY⟩, where Y represents the target galaxy property); Pearson ρ coefficient.
