Regularize the spatial curvature of a scalar-output image network using the paper's Burkholder integrand instead of an isotropic squared-Hessian norm. The energy is nonconvex pointwise but quasiconvex on symmetric Hessians, so compactly supported Hessian perturbations cannot lower the total energy relative to an affine field; this may suppress oscillatory curvature while allowing sharper anisotropic transitions than quadratic smoothing.
Replace an ordinary input-convex potential with a potential whose Hessian is encouraged to be symmetric positive definite and symplectic. Add a curvature penalty based on the scalar curvature of the Hessian metric, together with a theorem-derived interior target proportional to the inverse squared distance to the domain boundary. This should suppress pathological third-derivative oscillations while preserving nonquadratic structure near boundaries.
Use the hysteresis threshold as a regularizer for attractor diversity. Estimate how many initial states converge to each fixed point and select thresholds that maximize basin entropy or penalize domination by one attractor, reducing attractor collapse in discrete recurrent classifiers and memory modules.
Add a curvature-aware structural regularizer to a graph neural network or learned graph-rewiring module. The regularizer raises low-curvature edges toward the sharp 1/2 threshold, which is predicted to suppress first-dimensional cycle-space structure and reduce redundant or conflicting message-passing routes without explicitly computing graph homology.
Build a graph neural network on the dual graph of a triangulated surface whose messages are transported by \(\mathfrak{S}_3\) permutation matrices associated with adjacent-face color transports. This removes dependence on arbitrary local color-label choices and gives the network an explicit representation of noncontractible topology through holonomy around cycles.
Parameterize a nonnegative neural penalty or energy function as a sum of weighted power-mean differences applied to polynomial features of the network representation. Each atom is globally nonnegative by the power-mean inequality, so the learned penalty cannot become negative or destabilize constrained training, while the cone can represent polynomials outside SOS-plus-nonnegative-circuit certificates.
Add a spectral regularizer to a learned graph or sparse attention adjacency that penalizes violation of the paper's energy floor. The regularizer discourages adjacency matrices that retain many edges but collapse into a low-dimensional spectral structure, which may reduce graph-message-passing diversity and worsen oversmoothing.
Calibrate the scales of several additive self-adjoint residual or attention operators so their aggregate spectrum has a controlled higher-moment Berry–Esseen certificate. Penalize unusually large normalized (2+δ)-moments, which should reduce spectral outliers and make the summed operator closer to a predictable semicircle-shaped spectrum.
Add a two-output anti-collapse regularizer based on the determinant of the Jacobian Gram matrix, together with a penalty against proportional highest-degree coefficient tensors. The paper's inequality predicts that preserving coefficient non-proportionality prevents the output distribution from concentrating on thin curves or tiny regions, potentially improving coverage of a two-dimensional latent or generative output.
