Initialize directional prototypes, cosine-classifier weights, or angular attention directions with a spherical t-design rather than iid random vectors. Exact matching of spherical moments through degree t should provide uniform angular coverage and reduce initialization anisotropy, especially when the number of prototypes is small.

Replace a dense or ad hoc sparse attention pattern with a circulant mask generated by the paper's carry word c(m,k). Every query attends to exactly m of k relative positions, and the selected positions are prefix-balanced, avoiding the large gaps and collisions produced by random sparsification. Use several Farey-related slopes across heads or layers to combine local, medium-range, and long-range coverage.

Replace one local spatial aggregation in a CNN or vision transformer with a discretized Riesz potential whose kernel is proportional to $\|x-y\|^{-(n-s)}$. Normalize the layer using the paper's sharp weak-type constant and penalize empirical violations of the resulting tail bound, encouraging nonlocal context without allowing a small set of pixels or tokens to generate arbitrarily large responses.

Replace an unconstrained low-rank adapter or similarity projection with a learned subspace carrying a prescribed signed metric. The module learns an orthonormal basis U for a k=p+q dimensional subspace, forces the compressed form U^*I_{m,n}U to have p positive and q negative eigenvalues, and uses the resulting pseudo-inner product for signed attention or retrieval scores.

Replace or augment standard sinusoidal or RoPE position features with bracket-quadratic phases $e(-\theta n\lfloor\beta n\rfloor)$ generated by a Heisenberg nilmanifold orbit. Multiple irrational coefficients and output frequencies produce a cheap deterministic encoding whose empirical cross-position correlations should exhibit cancellation instead of the periodic aliasing of rational or finite-frequency encodings.

Parameterize a learned token metric as a nonnegative sum of sparse integral rank-one projections with unimodular support, rather than learning an unconstrained dense positive-semidefinite matrix. Graph-incidence covectors give an immediately implementable support family, while nonnegative coefficients guarantee positive semidefiniteness by construction.

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.

Apply a convex Husimi functional as a differentiable regularizer to positive matrices used by attention heads, routers, or feature covariances. Penalizing the squared response suppresses sharp spherical peaks and can prevent collapsed routing or unstable attention without directly forcing uniform eigenvalues.

Represent a small expert router or attention interaction by a homogeneous polynomial with nonnegative coefficients, then penalize violations of the Lorentzian Hessian signature on degree-two derivative slices. Initialize or warm-start the coefficient tensor from a normalized skew-Schur coefficient array, which the paper identifies as a realizable volume polynomial and therefore a structurally valid Lorentzian point.

Replace independent token scores with a query-conditioned positive-semidefinite low-rank quadratic score over a fixed-size selected subset. Repeatedly convert the quadratic objective into a linear exposure vector and apply a cheap top-k oracle, allowing the selector to model joint token interactions without constructing an n-by-n attention matrix. The margin between the current low-dimensional shadow and alternatives provides a practical confidence or early-stopping signal.

Build a differentiable assignment layer whose rows represent tokens and whose columns represent experts, memory slots, or attention slots. Each row has unit probability mass, but no column receives positive mass from two rows; maintaining at least one vacant column makes assignments continuously deformable through elementary vacancy moves instead of abrupt softmax switches.

Use the paper's lower bound on nearest-correlation repair cost to detect when a neural network's pairwise similarity predictions contain too much globally incompatible off-diagonal energy. Instead of projecting every predicted matrix onto the correlation cone, train the network to reduce the repair-risk statistic or trigger expensive repair only when a cheap diagnostic predicts substantial distortion.

Construct a finite neural prototype dictionary from solutions of Mα = α⁻¹, where the inverse is coordinatewise, and assign positive weights so the dictionary obeys the isotropy identity Σᵢ cᵢαᵢαᵢᵀ = I.

Replace raw polynomial interactions between neighboring feature vectors with central polynomial interactions computed after subtracting the local feature mean. Keep separate second-, third-, and fourth-order channels and apply independent residual gates to them, so a uniform shift of every feature in a neighborhood cannot create artificial cross-order responses. This is a drop-in higher-order mixer for a small transformer or graph neural network.

For every unordered pair of scalar features, construct invariant coordinates from the elementary symmetric quantities s=x+y and q=xy, then feed a truncated orthogonalized polynomial basis in (s,q) to the neural network. Estimate the basis by weighted Gram-Schmidt or Cholesky whitening under the paper's triangle weight, so polynomial channels have low redundancy and controlled scale instead of requiring an unconstrained MLP to learn both symmetry and decorrelation.
