Replace dense token-to-token attention on a 2D token grid with local attention plus sparse horizontal and vertical communication axes. Tokens at intersections of selected axes receive extra cross-axis attention edges, creating a reinforced sparse graph that can transmit information across large blocks while using far fewer edges than dense attention. The mask should use light-tailed, approximately geometric spacing in both directions rather than heavy-tailed spacing in one direction.

Replace independent top-k expert decisions by a global fractional routing problem that enforces token-side and expert-side capacities together with an additional diversity constraint represented by a partition or laminar matroid. Use the resulting Hall-type deficiency certificate to identify overloaded token subsets and penalize the actual structural cause of routing failure rather than relying only on an aggregate load-balancing loss.

Compress a module whose output changes with a scalar condition such as diffusion time, temperature, or compute budget by representing its response in a low-rank basis generated by resolvent-like functions. Distinct spectral modes produce rational factors \((1-\tau\lambda_k)^{-1}\), allowing a small number of learned components to approximate a large hypernetwork or condition-dependent parameter table.

Constrain a sparse attention graph to split into a k-degenerate backbone and a residual graph with maximum degree at most k-1. Orient the backbone according to a degeneracy order so that each token receives or emits at most k structured interactions in the relevant direction, while the residual edges form a bounded-degree correction layer. This replaces arbitrary sparse attention with a topology that is easier to schedule and whose worst-case edge and local-degree costs are explicit.

Represent a neural computation or verification pipeline as a directed acyclic graph whose nodes carry cached certificates for tensor shapes, numerical ranges, Lipschitz estimates, quantization error, or equivalence to a reference module. After locally replacing or optimizing one node, compare its old and new interface fingerprints and revoke certificates only along the dependency cone when the interface changed. This enables safe incremental verification during architecture search, compiler…

Replace a complex latent vector x in C^d by squared magnitudes of m learned complex linear projections. Set m equal to 2d: the paper proves that m less than or equal to 2d minus 1 cannot generically preserve the latent up to global phase, whereas m equal to 2d is generically sufficient, giving a principled minimal width for a phase-invariant neural bottleneck.

For a neural model whose outputs lie on a d-dimensional analytic family in a very high-dimensional space, replace the full output vector by 2d+1 or a modestly oversampled number of fixed Gaussian scalar measurements. The paper's theorem predicts almost-sure injectivity in the noiseless setting, so an inverse network or decoder can recover the same latent instance without processing the full observation. Because the theorem does not provide a noise-stability constant, use M=4d+8 or M=8d in the…

Construct a sparse token-mixing architecture by interleaving learned per-token transformations with fixed perfect-shuffle and cyclic-pile permutations. For n not a power of k, the generated permutation group is 2-transitive, so sufficiently rich sequences of generator words can expose every ordered token pair without constructing a dense N by N attention matrix.

Replace an unrestricted additive recurrent or fast-weight memory with a sign-selectable update: for each incoming update vector, choose between adding and subtracting it so that a smooth compact potential of the memory state is minimized. This is appropriate when the memory representation has sign symmetry, such as signed random features or a learned linear sketch; it is not a drop-in replacement for ordinary gradient updates where the sign carries semantic information.

Represent structured neural masks or routing states as order ideals of a finite prerequisite poset, then use a modular score whose exact minimizers are a desired decomposition-closed family of valid configurations. This replaces many pairwise constraint penalties with one additive potential that gives zero cost to every intended valid state and positive cost to invalid intermediate states.

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.

Replace a dense attention pattern by the exact intersection of a fixed or cheaply computed base graph H and a learned shared-label relation. Two tokens can exchange information only when they are adjacent in H and share at least one of d labels, producing a controllable structured sparsity pattern. The label count d becomes an explicit capacity and compute knob: increasing d enlarges the relation vocabulary without requiring a dense pairwise mask.

Replace part of an attention matrix with a mixture of fuzzy permutation matrices induced by short permutations. Each basis element represents an order-preserving k-token matching smeared over all embeddings into the sequence, while a balancing constraint makes the aggregate attention receive uniform global coverage. Retain a standard low-rank or local-attention residual so the structured branch does not prevent arbitrary content-dependent interactions.

Add a small number of latent region-offset variables to a graph or token-mixing layer, interpreting selected edges as low-permeability barriers that suppress cross-region information flow. Eliminate the latent variables analytically, yielding a visible-node update with a structured low-rank correction rather than adding persistent hidden node states. The module is intended to preserve within-cluster propagation while preventing oversmoothing or contamination across learned boundaries.

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.

Use the model's non-monotonicity result to make graph connectivity a learned resource rather than assuming that every extra edge helps. An edge router assigns transmission scores but also charges a source-side collision cost for exposing an infected node to many susceptible neighbors.

Replace independent softmax expert choices with a collision-free Markov router whose particles occupy expert positions on a one-dimensional or circular index lattice. A particle can move only to an empty neighboring expert, and the move rate contains a product of sine ratios that globally repels nearby assignments; this should reduce expert collapse and produce more evenly spread routing without requiring a separate pairwise diversity loss.
