Replace dense aggregation over patches, points, or graph neighbors with a state-dependent positive quadrature rule. A latent encoder produces the current manifold coordinate z, a small controller chooses a subset of entities, and a convex redistribution step assigns nonnegative weights so that the subset preserves the full aggregation on a learned feature basis. The method is especially suitable for neural operators and vision attention where many spatial entities are redundant along the data…

Construct a sparse directed attention mask over ordered tokens by treating token pairs as edges labeled by time or position. Apply a recursive three-hop spanner construction so that every dense temporal route has a sparse route using at most three times as many hops. Run attention only on the selected edges and use three sparse message-passing layers, or a small learned hop-composition block, to approximate dense causal attention.

Replace repeated high-dimensional quadratic interactions in a neural operator or world model with a reduced latent quadratic map whose basis-pair interactions are precomputed offline. The online computation becomes a small polynomial in latent coefficients, preserving quadratic interaction structure while avoiding repeated full-resolution contractions.

Replace ordinary dropout or soft sparsity penalties on a nonnegative spatial or token activation field with sublinear multiplicative stochastic dynamics. The field receives local diffusion or graph smoothing, while noise amplitude u^gamma vanishes at zero but is relatively strong near zero; this creates an absorbing zero state and may produce exact contiguous inactive regions. The module is suitable for feature maps, graph-node fields, token routing scores, or continuous neural operators.

Replace a sparse graph layer's separate edge transformations with one joint low-rank factorization of all transformations entering each target node. For target node i, concatenate the neighbor matrices horizontally, project all neighbor features into a shared low-dimensional receiving basis, and reconstruct one output; retain the self transformation exactly. This can reduce edge-parameter storage and message-passing FLOPs when the incoming block row has rapidly decaying singular values.

Replace random node or token subsampling by a subset selected to preserve the averages of low-frequency graph signals exactly or approximately. Build a graph over nodes or tokens, compute its Laplacian eigenspace, and choose a fixed-cardinality subset whose eigenvector moments match those of the full graph; use the retained subset for graph pooling or downstream attention.

Represent a higher-order neural computation as a bipartite incidence graph between node features and hyperedges, and assign each node-hyperedge incidence an anchor probability or learned anchor score. Add a regularizer that maximizes the predicted size of the surviving (k,n)-core under random node, hyperedge, or token dropout, thereby preventing structured pruning or routing from disconnecting essential higher-order computations. At inference, retain only incidences belonging to the predicted…

Construct a residual neural network or graph message-passing layer whose skip edges are sampled with probability proportional to their distance as $|i-j|^{-(1+\sigma)}$, while retaining a small local backbone. The paper's mechanism predicts that coarse-grained propagation is governed by the long-range kinetic operator and is therefore asymptotically insensitive to the particular Bernoulli graph realization, yielding controllable superdiffusive information transport without dense all-to-all…

Approximate a dense symmetric interaction matrix in a neural layer by \(\widehat A=C\widehat M C^{\top}\), but compute the small core \(\widehat M\) from a two-sided sketched least-squares fit rather than from the landmark principal submatrix. This preserves signed or indefinite directions and avoids exploding outputs caused by an almost-singular \(A(I,I)\).

Replace ordinary stride-2 pooling by a stochastic block-to-center map that is equivariant under global sign reversal and monotone in every input spin. For a binary feature channel, the layer computes the probability of a positive coarse feature from the number of positive fine features, samples or relaxes the resulting Bernoulli variable, and learns only a constrained scalar rather than an unconstrained pooling kernel. The same construction can be applied independently to channels or to graph…

Represent hierarchical or tree-structured hidden states on words over d symbols and replace a dense mixing layer by a noncommutative Toeplitz operator composed of shared word shifts. Coefficients are reused at every tree location, so the parameter count depends on maximum interaction depth rather than the number of nodes; an optional spectral penalty controls the amplification profile of finite-depth truncations.

At propagation time \(t\), interactions with effective distance larger than \(r(t,\varepsilon)\) are removed because their total reachability probability is bounded by a prescribed error budget \(\varepsilon\).
