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 an unconstrained recurrent or residual transition with a block-structured contractive realization whose input-dependent multiplier is a direct sum of bounded branches. The resulting layer has a built-in non-expansive energy bound on the chosen normalized input domain, while still allowing different branches to respond to different coordinates or feature groups.

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.

Store a finite library of successful robot configurations or action-conditioned waypoints and construct a smooth soft minimum of their distances. Use the negative distance gradient as a structured action prior, add a learned residual policy, and pass the combined action through a quadratic-program safety layer. This gives a neural controller an explicit attraction basin toward demonstrated solutions while preventing violations of known state constraints.

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.

Attach a symbolic sparse head to a neural encoder instead of using a dense final MLP. The head evaluates a library of learnable power-law and interaction terms on nonnegative learned features, jointly optimizes linear coefficients and exponents, and removes inactive terms with coefficient sparsity. This should provide a compact model with better relative-error behavior on positive targets spanning several orders of magnitude.

Model stochastic training or recurrent inference as a random dynamical system and penalize the exponential growth of volumes transported by its Jacobian. This converts the paper's entropy and volume-growth relation into a computable regularizer that discourages chaotic sensitivity while retaining directions needed for fitting.

Replace an unconstrained recurrent transition on several probability-valued latent states with a nonlinear Markov operator whose transition coefficients depend on pairwise inner products between the states. Enforce the paper's coefficient margin so the layer preserves nonnegativity and normalization for every input, avoiding exploding or invalid probability states while allowing state-to-state interference.

Replace or augment a mixture-of-experts router with a relative transverse-curvature score computed between experts, rather than relying only on the router MLP logits. Experts that provide a broader, less stiff local response in task-relevant directions receive higher routing probability, while common nuisance or spectator directions cancel from the comparison. The score is invariant under a common linear reparameterization of the routing coordinates and can be restricted to a low-dimensional…

Build a one-dimensional recurrent or neural-ODE model whose global generator is a sum of translated nearest-neighbour operators H = sum_i h_(i,i+1), and penalize the three-site Reshetikhin residual. The resulting model is encouraged to conserve its total local energy current, which should reduce secular errors in long-horizon rollout while retaining a local, parameter-efficient interaction structure.

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 ordinary dense or floating-point eigendecomposition of small Hessian or Fisher blocks with a sequence of rational Jacobi rotations. The rotations preserve Euclidean norms and can be stored using fixed-point coefficients, while approximately diagonalizing curvature so the optimizer can use separate coordinate-wise step sizes. This is especially relevant to low-precision training and blocks with mixed-sign curvature.

Replace an expensive global resolvent calculation for a recurrent or state-space transition operator by measurements on overlapping finite patches. Penalize patches whose shifted operator has small minimum gain, while adding the paper's explicit O(1/n) truncation penalty so that increasing the patch size produces a predictable tightening of the stability certificate. This targets non-normal transient amplification that is invisible to ordinary eigenvalue or spectral-radius regularization.

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.

Use three learned state-transition operators corresponding to three data axes, and train them to satisfy the paper's pullback-style interchange rule. For every local pair of axes, two successive updates should reach the same square state; for triples of axes, all six update orders should agree. This reduces sensitivity to scan direction and limits long-horizon drift caused by inconsistent local transitions.

Add an action-level exploitability penalty to alternating training of two neural policies that play against each other. For each observed state, estimate the value of forcing every available action against the opponent's current policy, then penalize positive gaps from the player's minimax value rather than relying only on the sampled action or episode return. This should expose locally exploitable decisions earlier and reduce oscillation between adversarial policies.

Train a neural network that predicts a symmetric matrix family without choosing a particular latent basis. In addition to matching pointwise eigenvalues, match gauge-invariant relational quantities formed by traces of products of matrices at several inputs; these distinguish matrix families that have identical spectra at every input but differ in their shared eigenvector geometry.
