Prime-Gated Maximal-Length Binary Reservoir

Replace a learned recurrent transition with a sparse binary reservoir compiled from prime-count gates. Three permanently active control vertices implement copy and XNOR transitions, allowing the signal state to realize an affine feedback register over \(\mathbb F_2\) with period \(2^m-1\) using only \(O(m)\) edges and bounded in-degree. Train only an input projection and readout, or use straight-through estimators if end-to-end adaptation is required.

Multiset Distance Positional Encoding

Add a permutation-invariant positional channel to a graph neural network by encoding each node through the histogram of shortest-path distances to a selected landmark set. Unlike standard ordered landmark distances, this representation is unchanged when landmarks are permuted and can be optimized to reduce node collisions. Use a small learned projection of the histogram alongside ordinary node features, with an optional collision penalty during training.

Crossover-Aware Multiscale Attention

Build a neural architecture whose receptive field or attention span is increased according to an estimated disorder-to-order crossover scale. Local branches process windows below the crossover as if they were stochastic, while a global branch is activated only when the context exceeds the predicted scale needed to expose deterministic recurrence. This targets sequences or images containing long-range quasiperiodic, hierarchical, or algorithmically generated structure that is statistically…

Spherical Height-Routed Multiscale Network

Replace an unconstrained deep routing tree by a q-ary descendant hierarchy with an explicit even height h=0,2,4,... labeling feature scale or computation depth. Train the router so that empirical occupancy of heights follows the exact even-sector law from the Nagao quotient, preventing concentration at shallow layers or unstable overuse of very deep paths.

Ensemble-Averaged Sparse Graph Search

Replace a binary neural connectivity mask by independent Bernoulli edge probabilities and optimize a deterministic expected message-passing objective before discretization.

Compact Abelian Graph Positional Codes

Replace one-hot node IDs or large positional encodings in a GNN with coordinates from a compact abelian Cayley graph. The coordinates preserve graph-shortest-path geometry exactly, while Fourier characters of cyclic factors provide smooth neural features with fewer channels.

Rayleigh–Jeans Condensation Routing

Replace softmax attention or dense MoE routing with a normalized Rayleigh–Jeans distribution over tokens or experts. If an item's energy is close to the chemical potential, its probability becomes disproportionately large, creating controllable low-energy condensation instead of the exponentially smooth allocation produced by softmax.

Masked Universal Host Layer

Represent many related sparse graph or attention patterns inside one fixed host connectivity pattern and activate each target instance with binary directional masks. The learned edge transformation and sparse-kernel layout are shared across instances, while the mask selects the target graph, enabling one compiled operator to process heterogeneous structures.

Matroid-rank interaction bottleneck

Construct a candidate feature for every edge pair or structured token pair, then retain a numerically independent subset under a feature-Jacobian matroid. The neural layer computes only the selected interactions, preserving directions that add new information rather than pruning solely by magnitude or attention score.

Build an implicit layer from a piecewise-linear maximal monotone operator on visible variables z_* and auxiliary variables z_**, then eliminate the auxiliary block rather than exposing it in the network output. Compute the layer through a fixed point of the eliminated component of a nonexpansive resolvent, with damping when the auxiliary map is not strictly contractive.

Apply a shared truncated exponential to these combinations and aggregate symmetric pairwise products, producing controlled quadratic and higher-order interactions without materializing a full trilinear tensor.

Random-label irregular sparse attention

Construct a sparse attention mask from a fixed regular candidate graph and one scalar random label per token, retaining edge $(u,v)$ when $x_u+x_v\geq\tau$. Unlike independent random pruning, this produces correlated neighborhoods and a controllable distribution of token degrees, potentially giving some tokens broad receptive fields while retaining a fixed sparse budget.

Peel-and-pass polynomial latent dynamics

Replace step-by-step hidden-state storage in a latent ODE, state-space model, or world model with a polynomial trajectory represented independently on short time blocks. At the end of each block, pass the next hidden state by summing temporal coefficients, allowing training and inference to discard the completed block while retaining a mathematically exact block interface.

Cyclic Non-Backtracking Mixer

Replace a dense token or channel mixing matrix by a fixed sparse directed graph whose states are ordered pairs of symbols and whose transitions advance through a cyclic phase. Each state has exactly two allowed successors, obtained by appending a symbol different from the previous two, producing a strongly connected, vertex-transitive sparse mixer with shared local dynamics. The prescribed phase structure prevents arbitrary short-cycle routing and can act as an anti-collapse inductive bias in…

Matroid-circuit equivariant message passing

Represent each matroid circuit as a structured hyperedge and perform message passing from circuit embeddings back to their constituent elements. Tie all circuit-update parameters that lie in the same automorphism orbit, so relabelings preserving the matroid produce exactly relabeled hidden states rather than requiring the network to learn this symmetry from data.

Tree-Cone Distribution Head

Represent a neural network's categorical output over a rooted tree using cumulative probability mass on each rooted subtree. Train pairs of examples with a stochastic-dominance loss that compares these subtree masses, avoiding enumeration of all upper sets and making hierarchical monotonicity explicit. This is suitable for taxonomies, severity levels, hierarchical intents, and structured world-model states.

Rank-safe Bernoulli layer initialization

Use the Bernoulli corank asymptotic to choose sparsity for binary or sparse linear layers and reject initial matrices with excessive numerical rank deficiency. The layer should also explicitly prevent zero columns, because the paper's probability law indicates that zero-column events are a leading mechanism behind large corank in the sparse regime.

Simplex-Complexity Depth Diagnostic

Estimate the simplex-based ratio of a target or learned convex piecewise-linear polytope and use the theorem \(\rho_\Delta(P)\le 2^d-1\) to choose a minimum useful ReLU depth. During training, monitor whether the learned polytope is approaching a high-\(\rho\) target; if it is, widen the model without increasing depth only when the diagnostic indicates that depth is the bottleneck.

Leading-Term Strand Router

Build a sparse neural mixing layer from colored directed strands rather than a dense all-to-all matrix. Feature channels are assigned ordered colors, local trivalent junctions conserve every color, and an edge width is the weighted sum of the colors carried by that edge; a differentiable penalty favors monotone, crossing-free routings that define a canonical leading term. This creates a structured routing prior that can be compared directly against dense attention and unconstrained sparse…

Boxicity-guided constraint attention

Replace an unconstrained pairwise attention score with an intersection of coordinate-wise threshold or interval compatibility heads. Each head is a supergraph that permits pairs satisfying one constraint, while the final attention edge exists only when every head permits the pair. This provides an interpretable inductive bias for multi-constraint relations and prevents the model from approximating a conjunction using a single unstable nonlinear score.

Collision-free ternary attention

Represent a sparse higher-order attention head by a 3-uniform hypergraph whose hyperedge $(v,x,y)$ allows anchor token $v$ to aggregate a pairwise interaction between tokens $x$ and $y$. During mask construction, greedily reject edges that would create a $4$-cycle in the link graph $L(v)$, so the same pair of source tokens cannot reach an anchor through multiple redundant pairings. This produces a diversity-constrained sparse attention pattern with an explicit, measurable collision bound.
