Descriptors from principal component analysis. Descriptors for a metals \(\{({t}_{i1},{t}_{i2})\}\) and b adsorbates \(\{({w}_{1j},{w}_{2j})\}\), obtained by PCA. The color scale in b measures the robustness of each species of being a predictor (\({\iota }_{j}\)). Those marked in brown are more suitable predictors, as they have large projections in at least one \({w}_{jk}\) and a low SD, Supplementary Eq. 12. Those marked in yellow are the least suitable. Relevant species are labeled
