Add a Fourier-domain residual loss whose per-frequency weight is determined by the geometric overlap of a convex bandwidth domain with its reflection about that frequency. Frequencies close to the boundary receive larger weight through \(\omega_\Omega^{-d}\), forcing the network to model fragile spectral components instead of optimizing only the high-energy interior. Use clipping or a bounded transform of the singular weight so that a few boundary bins cannot dominate training.

Train a scalar neural field on a bounded convex domain with a restricted half-Laplacian residual and an explicit strict-concavity barrier. The paper's theorem motivates requiring the learned potential to have negative-definite Hessian throughout the domain, while the nonlocal residual gives the model a global Cauchy-process-style inductive bias rather than only local smoothness.

Replace or augment the first embedding layer for antipodally identified inputs with the normalized traceless quadratic map from the Veronese construction. Because q and -q produce exactly the same feature, the layer enforces projective invariance by construction rather than learning it from augmented examples. The resulting matrix-valued features can be flattened, projected, or processed by an equivariant linear layer.

Replace a time-homogeneous recurrent update by a sequence of parameterized maps f_t, and regularize late-time pairs of updates to approximately commute: applying block f_t followed by f_r should agree with applying f_r followed by f_t. This should make long-horizon predictions robust to local time-step reorderings and schedule perturbations, while proximal statistics provide a diagnostic for whether trajectories repeatedly approach one another rather than diverging permanently.

Replace rejection sampling or coordinate random walks for adversarial and augmentation perturbations in a convex feasible set with Hit-and-Run: choose a random direction through the current perturbation, compute the exact feasible chord, and sample uniformly on that chord. The paper's spectral-gap result predicts faster global exploration when the perturbation polytope is rounded or whitened, while preserving feasibility at every step.

Apply a weighted Caffarelli–Kohn–Nirenberg deficit to selected intermediate feature channels. The penalty discourages features that obtain large weighted responses only by becoming sharply localized or highly sensitive to small input perturbations. It can be evaluated with input-Jacobian estimates and added to the ordinary task loss.

Replace an ordinary elementwise interaction between two feature matrices by a noncommutative functional-calculus layer \(\varphi(A,B)\), where \(A\) and \(B\) are Hermitian channel operators that need not commute. Add a soft penalty on \([A,B]=AB-BA\), and use a Besov-smooth parameterization of \(\varphi\) so that perturbations are controlled in Schatten \(p\)-norm for \(p\leq2\). This creates a principled matrix interaction module that can remain stable when feature operators or graph…

Replace the symmetric Euclidean contrastive loss between embeddings with a two-point quadratic contrast whose displacement is generated by a local affine connection and measured using the metric at the source endpoint. Because the metric and transport need not be compatible, the loss can be asymmetric, allowing the model to represent directional relations between examples.

Replace ordinary isotropic residual noise in a normalized continuous-depth block with projected Brownian forcing on the unit sphere. Apply a shared random symmetric quadratic drift to all tokens, plus a small token-specific tangent perturbation; the shared term preserves structured antipodal dynamics while the independent term removes persistent symmetry and cluster degeneracy. This is intended as a controlled stochastic regularizer, not merely additive Gaussian noise.

Construct a classifier whose normalized class vectors form an explicit 2d-line equiangular tight frame instead of using independently initialized weights. The ETF gives every class the same norm, equal pairwise coherence, and an isotropic frame operator, which should make final-layer gradients better conditioned and reduce accidental class crowding. The classifier can be fixed, or restricted to a learned unitary rotation of the ETF so that its geometry is preserved during training.

Add a metric-learning loss whose local geometry changes according to several learned or supplied boundary coordinates. Use a product conformal factor when violations of multiple constraints should accumulate, or a sum conformal factor when the most severe constraint should dominate; on a face where several coordinates vanish, impose the corresponding snowflake exponent on tangential distances.

For a neural model predicting a scalar response as a function of a continuous dynamical parameter, replace an unconstrained MLP output head by an analyticity-constrained spectral head. Train it on observations covering a positive-measure subset of the parameter interval and regularize the remaining coefficients so that the learned response satisfies a quasi-analytic derivative-growth bound; the intended benefit is reliable continuation from sparse parameter coverage rather than ordinary…

Replace pointwise pair interactions between mesh cells by quadrature of the interaction kernel over the full Cartesian product of the two cells. Decompose each cell pair into convex-hull pieces and apply a Duffy-like radial transformation so the coincidence singularity is confined to one quadrature coordinate, allowing fixed Gauss-Jacobi or adaptive quadrature to produce smooth, low-variance interaction features.

Replace a complex latent vector x in C^d by squared magnitudes of m learned complex linear projections. Set m equal to 2d: the paper proves that m less than or equal to 2d minus 1 cannot generically preserve the latent up to global phase, whereas m equal to 2d is generically sufficient, giving a principled minimal width for a phase-invariant neural bottleneck.

Constrain an embedding table to the unit sphere and penalize repeated or nearly repeated pair sums. This discourages additive quadruples a+b approximately equal to c+d, reducing unwanted linear structure and making distinct tokens less interchangeable under downstream composition.
