Replace a pixelwise density decoder with a decoder that predicts coefficients of a transport potential relative to a fixed reference density. The reconstructed density is the pushforward of the reference measure through a differentiable transport map, so positivity and total mass are structural properties rather than learned penalties.
Replace orthogonal Procrustes alignment between two latent dynamical systems with a learned bijection h that makes their transitions commute: h(f(z)) approximately equals g(h(z)). Parameterize h as an invertible affine map or coupling flow, allowing the correspondence to be non-orthogonal while retaining an exact inverse. The same constraint can be applied over multiple rollout steps, encouraging two models to represent the same computation even when their latent coordinates differ…
