Estimate the temporal spectrum of each sequence channel using a locally private procedure, then apply a regularized inverse-square-root spectral filter before the sequence enters attention or an SSM. The filter removes predictable low-frequency or narrow-band redundancy while avoiding unstable amplification at frequencies where the private estimate is small.

Replace unconstrained combinations of several attention or adapter operations with a brace-style composition that inserts each operation into a distinct ordered interval of a base sequence. The resulting computation preserves the order of host and inserted operations and forbids crossing dependencies, producing hierarchical attention patterns with an explicit structural bias.

Represent each of m neural branches by a positive input field f_i and a positive output field g_i, then penalize violations of the paper's multi-output Borell-Brascamp-Lieb bound at weighted barycenters. The constraint couples branches through both local normalized ratios and global mass ratios, encouraging calibrated multi-view predictions without requiring all output functions to be identical.

Construct a directional attention head whose admissible slopes are leaves of an M-adic interval tree with a prescribed finite splitting number. Instead of evaluating all K directions independently at every spatial location, route each query through only the branch decisions of the tree and share feature projections among directions that remain in the same multiscale angular interval.

Replace scalar entropy penalties on attention maps with a matrix-valued heat-flow regularizer over a circular or periodic token coordinate. Each position stores a positive semidefinite matrix describing coupled heads, experts, or channels; heat smoothing is constrained by the sharp modified log-Sobolev and Bogoliubov–Kubo–Mori contraction rather than an arbitrary smoothing coefficient. This should suppress high-frequency routing noise while preserving positive matrix structure and reducing…

Use an approximate decision diagram to select a structured subset of neurons, channels, attention heads, or attention edges when their quadratic interactions are sparse or inverse-sparse. Merge states that agree on a local interaction boundary and accept a tunable epsilon loss in the pruning objective, obtaining a representation whose size is linear in model width for fixed accuracy tolerance.

Represent candidate two-dimensional attention windows as dyadic rectangles and penalize local regions where many deeply embedded windows overlap. Use complementary horizontal and vertical depth exponents rather than independently penalizing one coordinate. The resulting router should reduce pathological concentration of sparse attention computation while preserving access to multiscale context.

Construct a sparse attention support by solving multiple small perturbed assignment problems between query and key embeddings and taking the union of the selected optimal matchings.

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.

Approximate a graph's adjacency by a learned abelian Cayley host and use one shared message-passing operator for every edge in the same inverse-pair generator class. Keep only the unexplained original edges as a residual branch, so the layer interpolates between a parameter-efficient group convolution and ordinary graph message passing.

Use the adjacency matrix of a vertex-transitive strongly regular graph as a fixed sparse attention or token-mixing mask. Every vertex has the same degree, and every pair of vertices has exactly one of two common-neighbor counts, giving predictable two-hop coverage and avoiding the degree and connectivity irregularities of random sparsification.

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 random or learned routing hashes for tokens arranged on a d by d grid with a fixed family of mutually orthogonal anti-Latin squares. Each channel assigns exactly d of the d squared tokens to every bucket, while any two channels jointly distinguish every grid position.

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.
