Replace raw powers or unconstrained polynomial spectral features with normalized Jacobi features whose amplitude is provably bounded on the entire input interval. Use trainable mixtures of these features in a positional encoding, graph spectral layer, or MLP front end, while preserving the theorem's normalization and optionally constraining the learned mixture norm.

Replace raw polynomial features in a scalar MLP expansion with endpoint-weighted orthonormal Jacobi features. The paper's envelope gives a degree- and parameter-aware scale for each feature, preventing high-degree terms or endpoint behavior from dominating gradients while preserving a richer approximation basis than low-degree monomials.

Replace a dense token- or channel-mixing matrix with a product of local braid generators acting on adjacent coordinates. Each generator is an exactly invertible 2-by-2 transformation, while the braid and far-commutativity identities give multiple equivalent factorizations of the same global operator. This creates a sparse, reversible mixer with O(kn) cost for a braid word of length k, rather than O(n^2) cost for a dense matrix.

Replace a dense learned polynomial-feature transform with a d-orthogonal recurrence whose production matrix is constrained to a (d+2)-banded lower-Hessenberg form. The layer generates successive features using only local recurrence coefficients, giving O(dN) arithmetic and O(dN) parameters for N basis functions instead of O(N^2) dense mixing.

Insert an overcomplete sparse feature bottleneck into an MLP or embedding stream: encode an activation h with z = ReLU(W^T h + b), then reconstruct or continue computation from Wz. Normalize dictionary columns and train them to remain nearly tight and low-coherence, while choosing a negative bias from an estimate of worst-case cross-feature interference. The hypothesis is that this gives cleaner, more stable feature supports than an ordinary L1 sparse autoencoder at the same latent width.

Construct a Fourier layer whose active frequencies lie on several nonparallel polygonal patches or thin annular sectors, and cap repeated difference vectors generated by pairs of patches. The bounded-multiplicity geometry limits how many input frequency pairs can contribute to the same output frequency, potentially reducing spectral aliasing and gradient variance in nonlinear Fourier mixing.

Interpret successive neural representations as an RG flow and constrain coarse-graining layers to remove unstable or redundant information monotonically. The paper reports monotonic decrease of an effective central charge along measurement-induced RG flows; a neural analogue can use a measurable information-complexity proxy and reject compression steps that increase it while preserving task-relevant information.

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.

Construct multiplicative neural gates directly on encoded tensors so that operands are multiplied coordinatewise without decoding between every operation. Polynomial evaluation makes this operation algebraically consistent with multiplication, allowing redundant gated MLPs or bilinear layers to retain fault tolerance while reducing the frequency of expensive correction steps.

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…

Augment a hidden representation with positively homogeneous interaction features built from approximate eigenmodes of a linear layer.

Replace a fixed quantile output with a Lambda-quantile head that receives a predictive sample set and applies a learned value-dependent threshold \(\Lambda(x)\).

Replace a dense channel-mixing matrix in a sequence layer with alternating diagonal propagation and sparse unipotent Stokes jumps.

Use the layer at which persistent connected components and holes disappear to allocate capacity nonuniformly across a network. If representations simplify much earlier than desired, widen the responsible layers or insert an additional block; if simplification is excessively delayed, avoid spending parameters there. This turns persistent-homology COM into an actionable architecture-search signal rather than a post-hoc visualization.

Replace a dense third-order channel-interaction tensor by a fixed sparse support selected through the paper's uniform-marginal infeasibility certificate. Supports with a large dual margin have an effective entropy base below the channel alphabet size, suggesting fewer independent interaction slices and cheaper contractions.

For each scalar activation, replace its empirical rank u by the cumulative interval map induced by the Type-III derangetropy kernel, optionally followed by Gaussian or affine output calibration. The transform is invariant to strictly increasing reparameterizations of the feature and contracts the marginal toward central ranks, potentially reducing sensitivity to heavy tails and outliers.
