Insert a fixed expander channel before a covariance-dependent feature transformation. The channel repeatedly conjugates the feature covariance by a constant number of sparse Pauli/CNOT unitaries, preserving total feature energy while contracting anisotropic covariance components. Use the mixed covariance for whitening or as a regularized normalization statistic, and test whether it gives more stable training than dense whitening or an explicit isotropy penalty.

Add a multiscale Besov penalty to the output of a shallow ReLU^k network, targeting the smoothness threshold that the paper proves is sufficient for finite ridge-variation representation. This suppresses pathological high-frequency output while preserving low-frequency approximation, providing a principled alternative to ordinary parameter weight decay.

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.

Use a sparse multivariate Legendre expansion as the geometry-to-network-weights map, rather than an unconstrained MLP that consumes all shape parameters. The hypernetwork predicts only coefficients for a selected set of polynomial multi-indices, allowing high-dimensional or countably parameterized shape uncertainty to be handled with a number of learned terms determined by coefficient decay rather than ambient dimension.

Replace an unconstrained hidden-to-hidden interaction in an MLP or transformer feed-forward block by two gauge-related branches. Split channels with an orthogonal involution Θ, constrain the learned interaction K to anticommute with Θ, and use opposite signs of K in paired branches. This creates a testable inductive bias in which the learned interaction only transfers information between the two channel subspaces.

Partition a neural network into heterogeneous parameter blocks or maintain several worker replicas, and model each block's optimizer state as a constrained linearized dynamical agent. At every synchronization interval, jointly optimize a finite sequence of parameter updates and a feasible common terminal parameter target, while enforcing consensus through distributed primal-dual iterations. Unlike ordinary gradient descent toward a fixed or implicit target, the target is selected together with…

Parameterize an orthogonal or semi-orthogonal neural weight matrix directly on the Stiefel manifold and update it with a Cayley retraction instead of unconstrained SGD plus a penalty or QR projection. The update preserves orthogonality exactly, is second-order accurate for the appropriate metric, and avoids the cubic QR factorization at every optimizer step.

Replace a neural controller's pointwise action outputs over a finite horizon with Bernstein control points whose convex hull satisfies actuator and trajectory constraints. The network predicts the control points, while a robust margin accounts for bounded tracking or model-prediction error, making continuous-time actuator feasibility checkable from finitely many inequalities.

Construct a generative or recurrent neural architecture with several contractive or mildly expanding branches, and explicitly control the geometric complexity of its invariant set using the sub-additive singular-value pressure of branch-Jacobian products. Instead of regularizing only the operator norm, the model can preserve anisotropic directions while targeting a desired attractor dimension, potentially improving coverage of structured data without uncontrolled folding or collapse.

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…

Regularize a neural representation so that no one-dimensional projection places too much probability mass inside a narrow interval. This transfers the paper's uniform tube estimate into an anti-collapse constraint, making representations robust to adversarial directions and preventing hidden features from becoming effectively low-dimensional.

Use cumulative control measures as the input to a neural surrogate instead of the full sequence of control values. For a quasi-static free-boundary system satisfying the paper's average-pressure path-independence assumption, two nonnegative control histories with identical integrals up to time t should produce the same state at t, allowing a smaller training input and fewer distinct control trajectories in the dataset.

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.

A large singular direction in A is penalized more strongly when the corresponding singular direction in B is also large, directly controlling joint feature amplification.
