Use the paper's edge-to-area incidence structure to choose a small set of geometrically independent simplices instead of processing every possible hyperedge. A greedy rank-increasing router retains a triangle only when its Jacobian adds a new direction, reducing higher-order message-passing cost while preserving diverse geometric information.

Represent a parameter objective locally as a difference of convex terms, compute approximate proximal points for both terms, and update parameters using the difference of their high-order Moreau-envelope gradients rather than the raw DC gradient. Start with the quadratic case p=2, then test p=4 as a sharper penalty for large proximal residuals; solve each proximal subproblem with a small fixed number of inner steps and decrease the smoothing scale during training.

Replace dense attention between grid-arranged tokens by a deterministic block-sparse pattern generated from modular permutations. In each block, connect row token i to column token p(i)=2i modulo B; because i, i-p(i), and i+p(i) are injective modulo B when gcd(B,6)=1, the pattern avoids repeated horizontal, vertical, and diagonal projections. Use shifted permutations across heads to increase receptive-field coverage while retaining structured sparsity.

Replace repeated rejection sampling from a neural proposal P with a Poisson race that selects one proposal candidate with exactly the target distribution Q. Candidate i receives a Poisson arrival time A_i and race score A_i divided by Q(X_i)/P(X_i); the smallest score wins. When Q is close to P in KL divergence, the selected index has low expected logarithmic rank, providing an adaptive compute budget instead of a fixed number of candidates.

Bootstrap the optimizer curvature scale from a deliberately nondegenerate pair of gradient queries, then perform steepest descent in lp geometry with a local secant backtracking rule. The method does not require a supplied learning rate, smoothness constant L, initial distance R, or optimum value f*, and it automatically uses the dual norm associated with p.

Choose the retained context length by balancing the statistical complexity of adding lag j against the squared prediction bias from discarding it. Unlike a fixed context window, the rule uses both the remaining-horizon spectrum and the estimated tail energy, allowing a model to expand or shrink its memory online.

Use the attention probability distribution over an ordered context to choose contiguous token groups whose pooled attention masses have entropy as close as possible to a prescribed upper budget R. Replace the corresponding key/value vectors by one weighted representative per group, preserving token order and reducing the KV-cache length from n to m. Unlike unconstrained token merging, the entropy constraint gives a direct control knob over how concentrated or diffuse the retained attention…

Replace dense token-to-token attention by a learned binary relation generated from a small number of hierarchical predicates, while rejecting masks that contain a fixed K_{t,t} biclique. The paper's incidence bound predicts near-linear active edges for these structured relations, giving sparse attention with a measurable worst-case complexity target rather than relying only on average sparsity.

Use the paper's heavy-ball recursion as a runtime diagnostic for momentum optimizers. Detect when recent parameter differences form an approximately periodic orbit or when the estimated local two-step transition matrix has spectral radius near or above one, then reduce the learning rate and momentum temporarily. This targets the failure mode proved in the paper: fixed momentum parameters can produce attracting cycles even on smooth potentials with bounded curvature.

Replace dense grid tokens or global spectral features with coefficients of compactly supported kernels centered on a nested hierarchy of spatial points. Encode an input field into coarse-to-fine coefficients, apply a neural map to those coefficients, and decode the predicted coefficients at arbitrary query locations; the contribution from each level provides an explicit multiscale output decomposition.

Use the weighted quadrature identity as a training or inference constraint for a compressed activation path: retain only a minimal set of binary evaluations and compute normalization or residual-energy statistics exactly on the modeled Rademacher component.

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.

Add a cheap spectral gate to a state-space model or recurrent event detector that decides whether multi-step lookahead can change the threshold decision. If the learned threshold readout is approximately a nonnegative left eigenvector of the transition matrix, use the current state only; otherwise activate predictive heads and search over a small horizon. This avoids unnecessary rollout computation while preserving early-warning behavior in oscillatory or rotating dynamics.

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.
