Replace ordinary reverse-mode differentiation through a long sequence of stiff relaxation updates with a projected adjoint that separates slow conserved features from rapidly relaxing residual features. The neural layer can use large outer time steps even when its internal relaxation time is very small, while reconstructing only the microscopic gradient component required by the preceding layer.

Represent a neural-network weight tensor by rank-one terms whose mode factors are selected from shared orthonormal bases, and impose the same basis alignment across tensor flattenings. 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.

Use a strictly upper-triangular block operator to represent interactions between ordered layers, experts, or token groups, and compute its inverse exactly with a finite Neumann series. Because nilpotency truncates the series after a known number of blocks, the module avoids an iterative solver while retaining controlled long-range interactions.

Use the paper's monotone allocation viewpoint to decide which parameters receive progressively more pruning, bit reduction, or update opportunities. A van der Corput order prevents a fixed early prefix of structured groups from being systematically over-pruned, while the logarithmic comb bound quantifies worst cumulative imbalance across nested groups.

Replace communicated floating-point gradients in synchronous federated or data-parallel training with one-bit threshold queries whose thresholds are sampled publicly before gradients are observed. Use several fixed geometric amplitude scales so the same protocol handles unknown gradient means and heavy-tailed client updates without an interactive localization round. Decode each coordinate from the scale whose neighboring estimates are statistically consistent, then apply the decoded aggregate…

Replace heuristic magnitude pruning in a layerwise convex reconstruction problem with safe screening based on a perspective relaxation of the cardinality constraint. A channel is removed only when a lower bound for every solution containing that channel exceeds the loss of a feasible incumbent; conversely, a channel is forced to remain when every solution excluding it is provably worse.

Replace a learned sequence-mixing matrix with a structured lower-triangular Sprugnoli operator whose square is exactly the identity. Applying the same operator in reverse reconstructs activations exactly, so it can be used as a reversible Transformer mixer or reversible channel permutation while retaining nontrivial long-range mixing.

Replace a generic recurrent update by a positive-state continuous-time cell whose interactions are restricted to a quadratic zero-one reaction-network motif with three state variables and six reactions. Select a motif known to possess three positive equilibria, then use the two stable equilibria as binary memory states and the intervening unstable equilibrium as the separatrix. This creates an explicitly multistable RNN module with a bounded attractor count and a measurable stability…

Build a neural feature-mixing block from a sparse exchange matrix and a fixed sequence of cluster-style mutations. Transpose-related channels share parameters through orbit tying, while positive multiplicative-additive updates are evaluated with log-sum-exp. The block is a concrete alternative to a dense MLP projection and can be tested at equal parameter count and compute.

Construct a symmetric token affinity matrix and approximate only its spectrally outlying token-mixing modes using a small set of sampled landmark columns. The resulting low-rank operator replaces an \(O(n^2)\) dense mixer by two skinny matrix multiplications, while the paper's residual guarantee predicts that large-magnitude global interaction modes are preserved.

Replace a learned nonnegative banded transition matrix by an ordered product of learnable stochastic bidiagonal factors. Each factor performs one local left or right transport step, so a product of p lower and q upper factors creates an effective bandwidth of p+q while retaining nonnegative entries, row sums equal to one, and a highly structured propagation kernel.

Replace unconstrained low-rank compression of a neural state with an augmented basis that always contains vectors representing known conserved quantities or diagnostically important linear statistics. After each learned transition, project the state back onto the affine constraint set with an exact minimum-norm correction, preventing rank truncation and model error from accumulating in those statistics.

Replace dense spatial attention on a 2D feature grid by attention from every non-landmark token to a small periodic set of landmark tokens. Choose landmarks using the paper's residue construction so that every non-landmark token has at least one landmark exactly k Manhattan steps away. Use this guaranteed edge as a sparse global-information route, combined with a cheap local convolution or residual path for accuracy.

Construct one reference Lanczos basis for a symmetric propagation operator H, then derive several seed-specific spectral responses for Q_a(H)x_0 through finite-band polynomial connectors. With degree-r seeds, each transformed basis vector uses at most 2r+1 neighboring reference basis vectors, avoiding a separate Lanczos factorization for every seed.

Replace an SVD-based pseudoinverse of a learned rectangular matrix with a low-degree polynomial initialization followed by a few Newton–Schulz iterations. The polynomial approximates the inverse Gram operator, while a cheap residual test accepts it only when the iteration is contractive and otherwise selects a conservative transpose-scaled initialization.

Replace random or degree-based graph positional anchors with a greedy set chosen to maximize the entropy of the graph's Weisfeiler-Lehman equivalence partition. Give each selected anchor a unique trainable embedding, then run several WL-inspired refinement rounds to produce positional cell features. The resulting positional signal should distinguish nodes that ordinary message passing treats identically while using only a small anchor budget.

Replace a dense Gaussian or learned projection from dimension N to m with a normalized partial circulant projection generated by a single Gaussian vector. For K-sparse hidden states, the restricted-isometry guarantee predicts approximate norm preservation while reducing stored projection parameters from O(mN) to O(N). The projection can be evaluated with an FFT and should be combined with explicit top-k gating so that the sparse-input assumption is enforced.

Replace direct source-to-target attention connectivity by two sparse incidence relations through a set of latent witness tokens. A source token attends only to a small set of witnesses, and each witness attends only to a small set of target tokens; the composed relation is trained to contain exactly one witness for desired pairs and no witnesses for undesired pairs. This produces a controllable sparse attention pattern whose errors can be measured entrywise against a dense teacher or known mask.
