GQL Safe Residual Layer

Insert a scalar flux-correction-style limiter after a neural operator predicts a conservative state or residual. Interpolate between a known-admissible baseline state and the learned high-order candidate, choosing the largest coefficient that satisfies a geometric family of linear inequalities encoding positive density, positive pressure, and subluminal velocity. This retains as much of the neural prediction as possible instead of independently clipping physical variables.

Collision-Aware Subset Attention

Replace ordinary one-token-to-one-expert or one-token-to-one-attention routing with a local latent subset router: a pooled observation can be explained by a compatible subset of tokens. Pairwise compatibility scores assign probability to subsets, and each token receives the marginal probability that it belongs to the selected subset. This should help when tokens represent overlapping objects, occluded entities, or multiple features that should be processed jointly.

Positive Mellin Mixture Gate

Replace a free-form order-dependent gate with a positive mixture of Mellin powers $(1+s)^{-a}$. This gives a small, interpretable module whose response across the order variable is automatically generated by a positive measure and therefore inherits complete monotonicity, log-convexity, and Hankel-moment structure.

Fast-Class MoE Router

Replace a flat stochastic MoE router by a two-level continuous-time routing model: experts within a group communicate rapidly, while transitions between groups occur slowly. Use the effective class-level stationary distribution as a soft load-balancing prior, reducing routing oscillation while preserving expert specialization.

Completely Monotone Multiscale Attention Decay

Parameterize a relative-position or lag-decay function as a finite positive mixture of exponentials instead of learning arbitrary attention bias values. The resulting kernel is completely monotone on positive distances, so it is nonnegative, decreasing, and has alternating derivative signs; the mixture provides several learned memory scales without allowing oscillatory or unstable long-range biases.

Markov-coded synchronization-robust latent streams

Replace an independently generated discrete latent sequence or redundancy stream with a symmetric two-state Markov source whose transition probability is tuned or learned. Train the downstream transformer to reconstruct the semantic target after random insertions, while using the paper's insertion-capacity expression to select the latent rate and redundancy budget. The representation should preserve information under timing drift, repeated tokens, and inserted distractors better than iid token…

Modular collision-free sparse attention

Replace dense attention between grid-arranged tokens by a deterministic block-sparse pattern generated from modular permutations. In each block, connect row token i to column token p(i)=2i modulo B; because i, i-p(i), and i+p(i) are injective modulo B when gcd(B,6)=1, the pattern avoids repeated horizontal, vertical, and diagonal projections. Use shifted permutations across heads to increase receptive-field coverage while retaining structured sparsity.

Path-Holonomy Attention

Replace ordinary additive path aggregation in graph attention with ordered products of edge operators equipped with learned reversal and color-switch maps. Closed-loop products become a consistency signal, allowing the model to retain direction-sensitive relational information that standard permutation-invariant message passing can lose.

Reversible Matrix Cluster Layer

Construct a latent layer whose node states are small positive-definite matrices and whose local updates follow a weighted cluster exchange relation rather than an unconstrained affine map. The update is reversible when the old state is retained, while noncommuting matrix products preserve relational structure that scalar cluster variables cannot represent.

Minkowski-Additive Convex Latents

This creates a structured residual or compositional layer where convexification is nonexpansive, making perturbation amplification controllable and avoiding repeated generic geometric optimization.

Dual-Rail Ratio Arithmetic Layer

Replace scalar neural activations by pairs of nonnegative channels whose ratio represents the signed or unsigned activation. Implement multiplication and addition through pair algebra, and renormalize each pair because the representation is invariant under multiplying both rails by the same positive scalar. This creates an explicitly bounded, cancellation-aware arithmetic layer for deep multiplicative MLPs, rational networks, and neural fields.

Wick-Matching Polynomial Interaction Layer

The resulting interactions are sums of products of power-sum invariants, with coefficients fixed by perfect-matching counts, providing a low-parameter inductive bias for permutation- or orthogonal-structured data.

Entropy-Budgeted Contiguous KV Pooling

Use the attention probability distribution over an ordered context to choose contiguous token groups whose pooled attention masses have entropy as close as possible to a prescribed upper budget R. Replace the corresponding key/value vectors by one weighted representative per group, preserving token order and reducing the KV-cache length from n to m. Unlike unconstrained token merging, the entropy constraint gives a direct control knob over how concentrated or diffuse the retained attention…

Biclique-free hierarchical attention

Replace dense token-to-token attention by a learned binary relation generated from a small number of hierarchical predicates, while rejecting masks that contain a fixed K_{t,t} biclique. The paper's incidence bound predicts near-linear active edges for these structured relations, giving sparse attention with a measurable worst-case complexity target rather than relying only on average sparsity.

The network predicts a local gauge-fixed field u and global coefficients a, then reconstructs the physical field as y = u + Ha, so local message passing does not need to synthesize global modes through many layers.

Positive Garside-factor tokenizer

Replace raw braid-generator sequences by sequences of positive simple Garside factors obtained from the left-greedy normal form. Because powers of \(\Delta\) lie in the Hilden subgroup, they can be removed while preserving the relevant double-coset presentation, reducing non-uniqueness and often shortening the sequence. Feed the resulting factor tokens to a Transformer or sequence classifier, and train it to be invariant to inserted removable \(\Delta\)-powers.
