Fig. 2: Two-dimensional maps of the chemical elements obtained by reducing the dimensions of the Pettifor embeddings (top panel) and of the one-hot embeddings (bottom panel).

The axes indicate the two dimensions returned by UMAP. The points are colored in both panels according to the group of the periodic table to which the elements belong. Comparison with other common embeddings is available in the ESI.
