Minkowski Attractor Networks: Closed-Form Hyperbolic Flows for Visual Representations

By framing hyperbolic manifolds as quadric level sets, MAN resolves hyperbolic geometry by combining linear Lorentz group transport with non-linear cone lifting and closed-form radial rescaling, evaluating in a single forward pass without numerical ODE solvers or iterative retractions.

Ananke: Contractive Torus Attractor Networks

Ananke is introduced, a representation-learning framework that scaffolds latent representations onto a structured product-torus prior, and its flagship visual backbone realization, Contractive Torus Attractor Networks (CTAN), and both exact trigonometric flows and hardware-friendly symplectic dual-shear variants are an...
