Use the paper's finite-width O(n^{-1/2}) Gaussian-process approximation bound as a width-budgeting rule rather than choosing every hidden dimension uniformly. Estimate an architecture-specific constant for each layer or attention contraction, then allocate width according to the smallest dimension satisfying its allowed distributional error. This should produce narrower models at comparable GP-like behavior, or permit the same parameter budget to be concentrated in the layers where finite-width…

Add a fractional Laplacian penalty to neural functions over binary inputs so that high-order coordinate interactions are damped according to \(|S|^\alpha\), rather than treating all Fourier degrees equally. The penalty is estimated with random continuous-time bit-flip perturbations, requiring only extra forward passes and no explicit Fourier transform. It is especially suited to models that overfit through high-order Boolean interactions while retaining useful low-order structure.

Replace a Gaussian regression likelihood with a chart-pulled exponential-family head. The network predicts a natural parameter eta, while each target y is mapped to a bounded probability coordinate u=G(y). Because the sufficient statistic T(u) is bounded, extreme targets cannot create arbitrarily large parameter gradients. The chart determines the tail class, while eta controls the distribution in probability space.

For bandlimited or progressively higher-frequency targets, construct a nested random Fourier layer whose frequency window grows according to the paper's bandwidth laws instead of sampling all frequencies from one fixed range. Train with a low-bandwidth subset first, then activate additional frequency blocks. This creates a mathematically motivated spectral curriculum and may reduce early optimization difficulty while preserving high-frequency accuracy.

Replace a finite-dimensional latent prior for fields or trajectories with a continuous flow acting on function coefficients in a separable Hilbert space. A Gaussian reference with an explicit covariance spectrum is transformed by a learned vector field, so the model can represent smooth, non-isotropic function distributions while sharing parameters across discretization resolutions.

Replace a dense Gaussian random-feature layer by a sparse Poisson-chaos layer with the same learned kernel, and penalize the layer's normalized fourth add-one energy. The penalty suppresses rare single-atom jumps, so the sparse layer approaches the Gaussian same-kernel representation in Wasserstein distance while preserving computational advantages from sparse Poisson sampling.

Insert a projection-space mixer that combines several fixed or learned directions using reciprocal correlations with the current feature, then normalize the result. The exact construction has a universal beta law for its squared input-output cosine, so it can create controlled angular diversity while remaining deterministic and independent of the chosen direction dictionary.

Replace a dense token-mixing, MLP, or low-rank-adapter projection with a Bernoulli-signed sparse matrix normalized by the paper's predicted operator scale. Estimate the active representation dimension and use the effective scale to detect regimes in which extreme sparsity is likely to cause unstable amplification or dead rows.

For a neural network predicting A coupled concentration or density fields, decompose Fourier-space fluctuations into a charge direction and its charge-neutral composition subspace. Hard-project the predicted fields to eliminate the global charge mode, and regularize their low-wavenumber covariance so that neutral modes retain finite susceptibility while the charge structure factor follows the Coulombic suppression S_ZZ(k) proportional to k squared. This should improve long-range physical…

Represent binary nuisance variables or augmentation bits as coordinates of a Hamming cube and penalize the model response that remains predictable from a random k-coordinate subset. Use the theorem's derivative-plus-global-norm certificate as the regularizer, retaining its p/log p dependence instead of using an arbitrary masking penalty. Random coordinate permutations provide a cheap stochastic approximation to the subset average.

Replace a dense directional feature map with a finite stable-zonotope layer: a small set of large random vectors creates a hyperplane arrangement over the input sphere, while a cheaper small-jump residual gives continuous features inside each cell. The layer exposes an explicit compute-versus-resolution knob through the jump cutoff and can be used either as an embedding before an MLP or as a lightweight router for mixture-of-experts blocks.

Use the paper's MBM-GP construction to predict input-dependent big-M constants for ReLU disjunctions during neural-network verification. Exact activation-bound optimization is performed only at a small subset of input points, while a Gaussian-process upper confidence bound supplies conservative bounds elsewhere, reducing verifier preprocessing and potentially tightening the MILP compared with one global worst-case constant.

Construct training and evaluation examples whose every (d-1)-variable marginal is exactly independent, but whose full d-variable distribution contains a parity interaction. This isolates genuine high-order reasoning from shortcuts based on pairwise or lower-order statistics and can expose whether attention or MLP architectures learn the intended interaction.

Attach a finite mixture of zonotopes to each uncertain neural input or hidden state, and propagate every mixture component through affine layers and conservative nonlinear relaxations. When the number of components grows, merge components only with an enclosing zonotope and sum their probability masses, preserving a formal lower bound on the probability that the true activation lies in the represented set.

Replace an unconstrained q-way polynomial or tensorized feature layer with separate decomposable and primitive interaction channels. The decomposable channel models interactions explainable as products of lower physical-weight feature blocks, while the primitive channel captures residual factors that cannot be represented by those products. This should reduce redundant high-order parameters and provide a controllable inductive bias for compositional or disentangled representations.

Use the min-plus phase transition as a training-time controller: begin near p = 1/2 to preserve the initial active-state fraction across depth, then move above or below criticality to deliberately remove or create sparse pathways. The controller uses a measurable state variable, the activation zero fraction, rather than an arbitrary regularization coefficient.

Initialize an invertible neural linear layer from a bounded discrete random matrix only after checking that every leading principal submatrix is nonsingular and that its LU growth factor is below a prescribed threshold.
