Replace a full-resolution global flow-matching or diffusion model with a hierarchy of local velocity fields operating on progressively finer grids. Coarse levels generate long-wavelength structure and pass it to fine levels through upsampling and residual conditioning, while every velocity network uses only a locality radius prescribed by the RG bound. This should preserve long-range correlations without quadratic global attention or a full-resolution global receptive field.

Replace recurrence or nearest-neighbour analogue lookup with a learned delay-coordinate observer that continuously corrects a latent state using the current observation. Constrain the observer's closed-loop Jacobian or linear state matrix to have spectral radius below one, so prediction error contracts geometrically and required burn-in grows logarithmically with target accuracy.

For a recurrent or graph neural network with known local connectivity, estimate each node's local Jacobian row using only graph neighbors rather than all hidden coordinates. Use the resulting sparse Jacobian both to compute a contraction certificate and to regularize training toward dynamically local interactions, reducing estimator variance and the number of samples required for reliable stability decisions.

Compress each hidden layer by retaining directions that are simultaneously reachable from the observed input distribution and observable at the network output. Unlike PCA or SVD, the retained subspace is weighted by downstream task sensitivity, so high-variance but output-irrelevant directions can be removed while low-variance predictive directions are preserved.

Build a label-free router for a finite library of neural operators by estimating one shared physical target response from an anchor prediction and using it to rank every candidate through inner products with candidate differences. The method avoids running a full residual-based diagnostic independently for every expert and can be used either to select the best expert or to form a corrected weighted combination.

Replace a dense Haar or Gaussian random projection with a streamed product of random two-coordinate rotations followed by coordinate subsampling. The transform is exactly orthogonal before subsampling, requires only a list of rotation triples, and the paper's pseudo-mixing result predicts that degree-two statistics relevant to norm preservation and Johnson–Lindenstrauss embeddings become Haar-like after only O(n polylog(n)) rotations.

Insert a linear Johnson–Lindenstrauss bottleneck around a set of jointly processed representations, choosing its width from the sharp finite-set dimension bound rather than from the model's nominal hidden size. The projection should preserve pairwise distances between tokens, patches, or retrieved items, allowing a downstream attention or MLP block to operate at lower width while retaining the geometry relevant to similarity computations.

Use trajectory sensitivities to remove neural units or parameter groups whose effects are redundant over the available data support. A parameter group is pruned when its Fisher contribution is small or its sensitivity is nearly collinear with other groups, producing a compact neural ODE without relying only on parameter magnitude.

Replace the single global MoE capacity factor with expert-specific capacity reservations chosen from a small reliability menu. Experts with highly variable or operationally important token loads receive larger robust buffers, while predictable experts run closer to their mean load. This should reduce token dropping and padding waste simultaneously, especially under distribution shift or bursty routing.

Construct overlapping attention windows from a block design instead of using one dense sequence-by-sequence attention matrix. Every token appears in exactly $r$ windows and every token pair co-occurs in exactly $\lambda$ windows, giving uniform coverage and avoiding the uneven connectivity of arbitrary sparse masks.

Split hidden dynamics into relaxation bands when the Jacobian spectrum has a gap, evolve each band with its own timescale, and retain an explicit cross-band exchange term. This yields a principled dual-timescale RNN or SSM rather than choosing fast and slow branches heuristically.

Partition tokens into a rectangular grid and use Latin-square labels to define several sparse attention heads. Each head attends only to tokens sharing a row, column, or Latin label, while orthogonality guarantees that every pair of labels occurs at most once, reducing systematic blind spots and repeated collisions. The resulting masks are deterministic, reusable across examples, and can be generated without learned routing scores.

Construct a graph of cheap prediction agents or reasoning traces and use a sparse set of expensive verifier calls as graph anchors. Select the next verifier location by the exact reduction in a trace-inverse coherence objective per unit cost, rather than by uncertainty or random sampling. This creates a budgeted mixture-of-agents architecture that can spend computation where it most improves global consensus.

Replace quadratic self-attention over a sequence with a bank of K auxiliary exponentially decaying states whose rates are fitted directly from the empirical autocorrelation of the sequence features. Each mode captures a distinct time scale, so the module can represent short- and long-range dependencies with O(TK) computation and O(K) recurrent memory rather than storing all previous tokens. Constrain decay rates to be positive and use the paper's extended Markovian block structure to obtain a…

Replace a weight-tied residual or neural-ODE stepper with an explicit Runge–Kutta method satisfying the reused-last-stage conditions. The final derivative is evaluated at the exact endpoint and becomes the first derivative of the next step, saving one expensive neural-vector-field call per step while preserving the designed integration order.

Prune hidden units only after testing whether their nonlinear gate is task-visible and downstream-used. For ReLU, a unit is removable when its preactivation does not cross zero on the task patch or its outgoing weight column is zero; this is a more structural criterion than weight magnitude and can be applied during width search or post-training compression.

Construct a sparse token-interaction graph from attention affinities and recursively split it by removing the closed neighborhoods of a small set of separator tokens. Separator tokens retain global communication, while the resulting anti-adjacent components perform local attention independently, reducing quadratic attention and KV-cache costs.

Enumerate structured pruning masks only up to exact permutations of exchangeable channels, hidden units, or experts. Replace exhaustive mask search with canonical augmentation: retain a subset only when it is lexicographically smallest among all masks obtained by the model's symmetry group, while recursively generating only canonical predecessors.
