Refinement-consistent bipartite routing

Represent hierarchical routing decisions by one weighted bipartite graph between parent experts or regions and fine cells or token groups. Select a regularized edge set once, then derive both coarse parent activation and fine-grained routing from it, preventing later refinement from invalidating earlier load balancing.

Certified Component Projection for Learnable Graphs

Insert a projection step after a graph neural network proposes edge weights, replacing the proposed Laplacian by the closest valid Laplacian with a prescribed block-component structure. The projection removes cross-block interactions while minimally changing within-block weights, and a block spectral-gap constraint guarantees that each block is connected rather than accidentally splitting into smaller components.

Probability-Preserving Zonotopic Neural Uncertainty

Attach a finite mixture of zonotopes to each uncertain neural input or hidden state, and propagate every mixture component through affine layers and conservative nonlinear relaxations. When the number of components grows, merge components only with an enclosing zonotope and sum their probability masses, preserving a formal lower bound on the probability that the true activation lies in the represented set.

Polymatroid Exchange Router

Replace overflow dropping in a mixture-of-experts layer with a discrete-convex load repair procedure. The router first chooses experts from neural logits, then applies capacity-aware exchange moves that preserve the total number of dispatched tokens and monotonically improve the routing objective whenever a feasible swap exists.

PSD-Relaxed Multiplicative Gate

Replace an unconstrained multiplicative interaction between two nonnegative neural features by a lifted gate whose first and second moments satisfy the paper's semidefinite relaxation for the set F = {(x1,x2): x1,x2 >= 0, x1 x2 <= 1}. Insert the gate into an MLP, attention score, or MoE router to prevent explosive feature products while retaining a tractable convex feasible set.

Use the inferred design structure matrix as a hard mask or soft gate on recurrent, state-space, graph, or mixture-of-experts couplings, replacing a dense unconstrained interaction matrix with a data-supported sparse graph.

Differentiable Octahedron Message-Passing Layer

The layer propagates information between two time slices while preserving the paper's characteristic tropical local consistency, which may provide a parameter-efficient inductive bias for grid reasoning, image patches, or graph layouts.

The controller stops when the calibrated expected terminal error is no greater than the cost plus expected value of executing another neural block, permitting time-dependent and nonmonotone stopping regions.

Ambiguity-Flat Weyl Feature Layer

Replace a random cyclic filter bank or patch projection with the Weyl–Heisenberg orbit of one normalized learnable prototype. Regularize the prototype so that all nonzero shift and modulation correlations have a large and nearly equal magnitude, maximizing the smallest eigenvalue of the induced feature Gram matrix and preventing poorly observed feature directions.

Successive Orthogonal Innovation Blocks

Add a neural feature, adapter, or expert block only through the component of its outputs that is orthogonal to the span of all previously installed blocks. Quotient coefficient directions that produce nearly identical outputs with an SVD or pseudoinverse, so the new block contributes intrinsic representational dimensions instead of duplicating old features. The expected benefit is a smaller effective architecture and better-conditioned block expansion.

Tree-Hall Collision-Free Router

Replace independent top-k routing by a tree-structured hypergraph assignment layer. Each candidate route is a singleton or pair of resources, and the router selects exactly q_e routes for every tree edge e while ensuring that no resource is consumed twice. This removes capacity collisions before expert computation instead of repairing them with token dropping or load-balancing penalties.

Vector-Balanced MoE Routing

Replace count-only MoE load balancing with greedy balancing of aggregate token-feature vectors.

Minimax-balanced progressive MoE splitting

Grow a mixture-of-experts layer by splitting one expert into two children while conserving its routing mass, and choose the split ratio to minimize the worst imbalance over all intermediate expert counts. Use the paper's sharp threshold as a hard design target: with n experts, some intermediate stage must have capacity ratio at least D_n = 2^{1-1/\lceil n/2\rceil}, so schedules substantially below this are impossible rather than merely difficult to discover.

Round allocations downward rather than to the nearest lattice point, preserving per-example capacity feasibility, and train or evaluate against the resulting granularity ratio rather than treating discretization as an implementation detail.

Replace top-k token pruning by greedy maximization of a diversity-aware monotone submodular utility under a spacing or coverage constraint. The selector repeatedly chooses the feasible token with the largest marginal utility, avoiding the redundant-token failure mode of independent score ranking while inheriting a constant-factor approximation guarantee under the stated 2-system abstraction.

During or after training, retain the largest coefficients to obtain a structured truncation analogous to truncated SVD. This should produce better-conditioned tensorized layers than unconstrained CP factors while preserving a directly controllable accuracy/compute tradeoff.
