We highly encourage readers to explore our interactive visualization of the latent space at simonensemble.github.io/latent-cage-space; upon hovering the mouse over a point in latent space, an image of the cage structure displays to facilitate interpreting the latent space. We duly address that any set of invented features of a porous organic cage molecule stacked into a vector technically serves as a latent space of cages. For example, let the first entry of vector x ∈ R 2 be the diameter of the largest included sphere in the cavity and the second entry be the molecular mass of the cage; the set of all x defines a 2D latent space.
