Gaussian Extreme-Logit Calibration

Normalize attention or router logits and control their upper tail using the paper's sharper Gaussian-maximum exponent rather than a correlation-blind sub-Gaussian bound. Use the resulting threshold to add a soft penalty or adaptive temperature whenever the observed maximum exceeds the calibrated level, reducing rare one-token or one-expert domination.

Geodesic curvature regularization for hidden trajectories

Represent a sequence of hidden states as points on a Riemannian sphere and penalize discrete geodesic curvature rather than merely penalizing adjacent-state differences. The regularizer discourages sharp bends in representation trajectories while remaining comparatively insensitive to uniform traversal speed, making it suitable for transformer depth trajectories or diffusion denoising paths.

Signed Partition-Path Attention

Replace one dense attention layer with a sparse hierarchical attention module whose states are clusters of tokens and whose transitions merge two clusters or reverse a previous merge. Enforce the flag-space cancellation law on pairs of alternative two-step merge paths, so redundant hierarchical routes destructively interfere instead of producing duplicated features. Normalize merge-then-unmerge loops using the product of the sizes of the merged clusters, preventing large clusters from…

Flip-Order Local Reconfiguration

Use local split-fusion rewrites as a structured alternative to globally recomputing token clusters. A model proposes a small number of neighboring tree edits per input, accepts only valid edits that reduce a learned energy, and retains the previous hierarchy across layers or decoding steps.

Non-crossing d-arc sparse attention

Represent sequence positions as vertices on a circle and use a maximal family of mutually non-crossing d-arcs to define the allowed attention interactions. Rotate the family by d positions, or use several phase-shifted families across successive layers, so each layer has only O(N) edges but repeated layers propagate information over long distances. The geometric compatibility rule replaces arbitrary local-window or hand-designed sparse masks with a structured family whose maximality gives broad…

Signed-triangle Nyström lookahead

Replace one-step greedy landmark selection in Nyström attention or kernel compression with a restricted pairwise-lookahead rule. The lookahead is motivated by the paper's explicit obstruction: a signed triangle can make individual column gains exhibit increasing rather than diminishing returns, so the best next column need not belong to the best pair.

Yang–Baxter Pairwise Router

Replace unconstrained pairwise token-routing interactions with a structured two-token router derived from an involutive set-theoretical Yang–Baxter solution. The pair operator is a convex interpolation between identity and a permutation of discrete routing states, so it cannot amplify probability mass or logits when applied to routing distributions. The Yang–Baxter relation provides a falsifiable test for whether three-token routing updates are insensitive to the two admissible…

High-Degree Jordan Anchor

Preprocess a noisy input graph into a high-degree core and compute a Jordan-center anchor in that core. Feed each node its distance to the anchor, and optionally use the anchor to bias graph-transformer attention; the hypothesis is that this suppresses spurious low-degree noise and gives the network a stable global coordinate system.

Worst-pair hyperedge smoothness

Add a hypergraph p-Laplacian penalty to hidden representations of samples or tokens grouped by a known relation, such as augmentations of one image, mentions of one entity, or tokens in one retrieved semantic cluster. Unlike mean pairwise smoothing, the penalty targets the maximum weighted discrepancy within each hyperedge, preventing a single representation from becoming an outlier while allowing moderate variation among the remaining members.

Centrally Extended Fourier Mode Mixer

Construct a neural mixing layer on Fourier or positional modes using a small set of exponentiated Virasoro generators instead of a dense mode-to-mode matrix. The generator coefficients are shared across all inputs, while the Lie bracket fixes how different mode shifts interact; an optional central channel captures the special coupling between modes whose indices sum to zero.

Følner Block-Replacement Curriculum

Construct augmented sequences by tiling long contexts with large finite blocks sampled from a library whose local-pattern frequencies match a target dataset, replacing only block interiors and leaving boundary zones untouched. This produces globally coherent synthetic contexts while controlling the distortion of short-range statistics through an explicit boundary-to-volume ratio.

Incremental Gray-code counter state

Use the one-edit Hamiltonian walk as an explicit state machine for counters in autoregressive models or world models. Instead of regenerating and re-embedding an entire numeric string after every increment, update only the digit that changes, or append the single leading digit at a block transition.

Descent-Set Shuffle Composition

Represent each sequence chunk by a distribution over local descent-set patterns, then compose two chunks using the shuffle-algebra product rather than concatenating their embeddings alone. The module explicitly models how local order statistics change under interleaving, providing an inductive bias for event streams, code tokens, time-series segments, or mixtures of independently generated sequences.

Additive-energy sparse offset design

Learn or select sparse cyclic convolution or relative-attention offsets whose pairwise differences collide less often modulo the sequence length. The paper's Fourier fourth-power identity turns this combinatorial objective into an FFT-computable differentiable loss, enabling fixed-K sparse patterns with lower aliasing and interference than random offsets.

Monadic Bar Refinement Network

Aggregate the resulting representations with a learned or fixed realization weighting, while training an algebra-action map θ:ΓY→Y to make one-step refinement compatible with the original representation.

Delocalization-regularized sparse masks

Use eigenvector delocalization as a mask-quality criterion rather than selecting a random sparse graph blindly. Penalize masks whose normalized adjacency has concentrated leading eigenvectors or disconnected or weakly connected components, while preserving the power-law distance prior. This creates a sparse routing graph that is less likely to trap information in local regions.

Criticality-Gated Resolution Switching

Use effective coupling and field values from a local coarse-grained motif to decide whether a neural network should operate at fine or coarse resolution. Near the continuous critical boundary, retain fine-scale features because correlations become long-ranged; away from criticality, aggregate aggressively. Near discontinuous or reentrant boundaries, hysteresis prevents rapid switching between resolutions.

Cyclotomic-Quotient Phase Embedding

Build a deterministic complex-valued embedding for discrete IDs by evaluating finite-field polynomials through an additive character, but learn coefficients only for one representative of each Frobenius or cyclotomic orbit. The quotient removes parameters that generate exactly the same feature function after the trace map, avoiding flat optimization directions and reducing the size of the embedding layer.

Porous Fourier concentration regularizer

Add a loss that prevents an intermediate feature map from being simultaneously concentrated inside a porous spatial region and a porous frequency region. The regularizer is based on the fractal uncertainty inequality: if frequency support is restricted to a porous set Y, then the fraction of feature energy inside a porous spatial set X is at most C h^beta; violations of this bound are penalized.

Ground-State Fractional Attention

Replace or augment relative-position attention with a positive fractional-integration mixing kernel whose radial behavior has separate inner and outer power laws. Tokens close to one another interact through the usual fractional singularity, while tokens near different radial scales receive a ground-state correction that can improve multiscale information transport without introducing a dense learned positional table.

Dyck-Polytope Sparse Routing

Replace independent top-k expert or attention-edge selection with a gate vector constrained by hierarchical path budgets modeled on the paper's extended-Dyck-path polytope. Ordinary interactions receive continuous nonnegative capacities, while a designated class of cross-group interactions receives binary or clipped-to-one gates, producing structured sparsity and preventing many correlated paths from consuming the same routing budget.

Takagi-Regularized Hierarchical Routing

Represent MoE experts as leaves of a balanced ternary tree and regularize the hierarchical boundary of each expert's assignment mask. At fixed routing mass x, the ternary martingale isoperimetric theorem supplies the explicit minimum one-variation T_3(x), so the router can be penalized according to an occupancy-dependent profile rather than a uniform parent-child disagreement cost. This should favor coherent, stable routing regions while preventing small expert supports from obtaining…

Zoomed and Pole-Safe Rational Activation

Use a barycentric rational activation or filter whose interpolation nodes are periodically zoomed into the range of preactivations or eigenvalues actually encountered by the network. Protect the layer from catastrophic poles by monitoring the associated generalized eigenproblem and penalizing poles close to the active input interval. This targets rational networks whose expressivity comes from localized poles but whose training is destabilized by denominator zeros.
