Replace the usual random or elementwise-positive linear-attention feature map with a rank-one positive-semidefinite feature map derived from query and key vectors. For normalized inputs, the resulting kernel is the squared inner product, which is nonnegative and gives a geometrically structured interference pattern that is better suited to associative recall than an arbitrary low-rank feature map.

Replace a dense directed attention matrix by a collection of K learned source-to-hub-to-target interactions. Each hub corresponds to a directed biclique, allowing many source tokens to communicate with many target tokens using O(NK) rather than O(N^2) pair interactions. The construction preserves asymmetric information flow and can be initialized from a graph cover of high-attention edges.

Replace token-by-token KV storage after an SSM or recurrent encoder with an online allocate-on-novelty cache. A new slot is created only when the incoming key is sufficiently dissimilar from every stored key; otherwise the incoming value is merged into its nearest slot, so repeated or redundant content does not grow the cache.

Represent a batch of token or feature directions as columns of a matrix X, and construct a complementary feature basis Y whose columns are annihilated by X under a diagonal gauge. Use Y as a second algebraically complementary channel for attention or token mixing, either replacing redundant feature projections or regularizing them toward an exact nullspace relation.

Replace dense token-to-token attention by a multiscale spiderweb communication pattern. Tokens first aggregate upward through a dyadic hierarchy, communicate horizontally only with a small number of cells at the appropriate height, and then receive information broadcast downward. Hyperbolic distance supplies a principled rule for choosing the height at which two tokens interact: nearby tokens interact at fine scales, while far-apart tokens interact through coarse representatives.

Replace unconstrained softmax cross-attention with a many-to-many transport matrix whose row and column masses have explicit upper bounds. Compute the attention cost from both feature similarity and pairwise relational disagreement, so a token is attended to only when its relationships to other tokens are jointly compatible. The inequality constraints provide a principled dustbin-free mechanism for ignoring distractor tokens.

Replace dense coarse-to-fine cross-attention at multiresolution interfaces with a sparse, nonnegative overlap operator whose weighted feature average is exactly conserved between the two resolutions. Use this operator as a low-order path and blend it with an unrestricted neural cross-attention path through a convex limiter that keeps features inside a box or simplex domain. The construction is especially suitable for adaptive token grids, hierarchical graph neural networks, neural operators…

Construct a spatiotemporal neural block from localized functions of a learned parabolic operator instead of unrestricted attention or convolution. Use one filter for fine-scale diffusion and another for coarse-scale temporal aggregation, with the scale ratio controlling information propagation. The block should suppress distant interactions while still permitting long-range mixing through coarse filters.

Use separate measurement-domain and target-domain token sets so a network can infer a field on one spatial domain from sparse observations on another in one forward pass. The same decoder can answer arbitrary target query points, avoiding an optimization loop for each inverse instance.

Replace dense attention weights with a compactly supported anisotropic bump derived from the obstacle solution, using one learnable ellipsoid per attention head or feature group. Tokens outside the learned ellipsoid receive exactly zero weight, while tokens inside receive smoothly decaying weights according to a fractional exponent. The learned positive-definite matrix represents orientation, scale, and correlations between feature dimensions.

Replace an unconstrained spatial gate or interpolation kernel by a compactly supported function whose translates under a lattice exactly sum to one. Impose zero products between translates under a second lattice, so active gates do not collide; thresholding a positive superlevel set then provides a nonzero separation margin and predictable sparse computation.

Replace dense spatial attention on a 2D feature grid by attention from every non-landmark token to a small periodic set of landmark tokens. Choose landmarks using the paper's residue construction so that every non-landmark token has at least one landmark exactly k Manhattan steps away. Use this guaranteed edge as a sparse global-information route, combined with a cheap local convolution or residual path for accuracy.

Represent each Euclidean input point by its responses to randomly sampled half-spaces, then center those responses by the minibatch or source-distribution half-space occupancy.

Turn the paper's graphon refinement operation into an adaptive mixture-of-experts or relational-attention router whose number of blocks is learned rather than fixed. Split a block when its members produce incompatible constraint gradients, and merge blocks when their relation rows are statistically indistinguishable, yielding a compact architecture that grows only where the data require extra structure.

Replace explicit quotient construction by a differentiable projection that removes learned group-orbit directions from both source and target features.

Replace independent top-k MoE routing with a submodular polyhedral allocation over experts. A learned set function assigns a marginal gain to each additional expert allocation, so the router exhibits diminishing returns and can enforce global capacity constraints rather than making unrelated per-token choices. The allocation is obtained by sorting marginal gains, giving a fast greedy router with piecewise-linear routing regions.
