Machine learning subfields define useful representations differently: disentanglement strives for semantic meaning and symmetries, identifiability for recovering the ground-truth factors of the (unobservable) data generating process, group-structured representations for equivariance. We demonstrate that despite their merits, each approach has shortcomings. Surprisingly, joining forces helps overcome the limitations: we use insights from latent space statistics, geometry, and topology in our examples to elucidate how combining the desiderata of identifiability, disentanglement, and group structure yields more useful representations.
