Each grey point represents a possible composition given the number of atoms in the nuclei. The color around each point shows the relative weight of that region of the composition space. The composition area sharing the same weight increases with the decreasing number of atoms from (a) to (c)...

Many atomic descriptors are currently limited by their unfavourable scaling with the number of chemical elements S e.g. the length of body-ordered descriptors, such as the SOAP power spectrum (3-body) and the (ACE) (multiple body-orders), scales as (NS)
