Correlations of latent features with atmospheric parameters.
| Target feature | zM | zC | zα |
|---|---|---|---|
| [Fe/H] | 0.92 ± 0.01* | 0.05 ± 0.08 | 0.30 ± 0.11 |
| [C/Fe] | 0.33 ± 0.08 | 0.92 ± 0.01* | 0.09 ± 0.03 |
| [α/Fe] | 0.33 ± 0.07 | 0.09 ± 0.03 | 0.82 ± 0.02* |
| Teff | 0.03 ± 0.01 | 0.01 ± 0.01 | 0.03 ± 0.02 |
| log g | 0.03 ± 0.01 | 0.01 ± 0.01 | 0.03 ± 0.02 |
Notes. Average and standard deviation values of the absolute Pearson correlation coefficients r between each latent feature and stellar parameters are computed over the test sets. The asterisk (*) highlights the correlation between each chemical abundance and its associated latent feature. Low correlations with Teff and log g indicate successful disentanglement from nonchemical parameters. The strongest correlations align each latent feature with its intended chemical abundance, confirming effective specialization in the latent space.
