Replace fixed-strength projection or constraint-repair steps during low-rank neural fine-tuning with a regularized affine subproblem whose damping is proportional to the current distance from the model manifold. Use strong damping when a gradient update leaves the low-rank manifold substantially, then automatically remove the damping near a clean intersection so that the method can recover higher-order local convergence. This is suitable for LoRA-style updates, structured matrix compression…

Add a two-sided cone-restricted spectral penalty to a recurrent or state-space model. Instead of estimating growth using a symmetric singular-value surrogate, jointly optimize a positive right vector and positive left vector in the extended quotient from the paper, targeting a real generalized eigenvalue of the learned non-selfadjoint transition operator.

Represent a parameter objective locally as a difference of convex terms, compute approximate proximal points for both terms, and update parameters using the difference of their high-order Moreau-envelope gradients rather than the raw DC gradient. Start with the quadratic case p=2, then test p=4 as a sharper penalty for large proximal residuals; solve each proximal subproblem with a small fixed number of inner steps and decrease the smoothing scale during training.

Replace spectral-radius-only stabilization of a recurrent or state-space transition matrix with a numerical-range constraint.

Replace the usual softmax router or soft one-hot penalty with a vector-valued phase-field regularizer whose low-energy states are exactly the expert one-hot vectors. Component-wise barriers create stable categorical phases, while a weaker coupling term suppresses invalid states such as the all-zero vector or multi-expert activation; annealing \(\varepsilon\) produces increasingly discrete routing.

Insert a weighted negative-semidefinite fourth-order mixing operator into a residual or state-space layer. Instead of learning an unconstrained token-mixing matrix, parameterize its dissipative component as Q = -a W^{-1} B^T W B, ensuring that this component cannot increase the chosen weighted feature energy. Use a boundary-aware finite-difference matrix B along the sequence axis, optionally with learnable banded coefficients while preserving the factorization.

Add a diagnostic and optional regularizer that measures whether a neural block's multi-step directed interactions differ strongly when traversed forward versus backward. This catches transient directional amplification in deep acyclic or nearly nilpotent networks, which eigenvalue or spectral-radius penalties can miss because all eigenvalues may be zero even though short directed walks are large.

Replace the random or gradient-aligned perturbation in sharpness-aware minimization with a unit perturbation direction selected by a polynomial of the local Hessian. With \(\mathscr{P}(s)=(s-\rho)^2\), the direction converges toward Hessian eigenspaces whose eigenvalues are closest to the target curvature \(\rho\), allowing regularization of a chosen curvature band instead of indiscriminately penalizing only the sharpest direction.

Add a loss term requiring a neural optimizer or recurrent module to decrease a nonnegative Lyapunov-like energy over M update steps, rather than forcing monotonic one-step decrease. The term includes an empirically estimated mismatch allowance, so stochastic or delayed updates are tolerated while persistent instability remains penalized.

Regularize a neural dynamical map so that its log-volume expansion is cohomologous to a constant rather than forcing the Jacobian determinant to be constant at every state. Learn a scalar potential that explains transient expansion and penalize only the non-telescoping component, which should reduce long-horizon gradient explosion or collapse while retaining useful average expansion.

Replace or augment a low-dimensional recurrent transition with affine maps whose linear parts belong to a structured unipotent holonomy family, and train the cell so that positive accumulated translation produces a controlled projective attractor.

Use the paper's multicycle result to distinguish useful parameter motion from internally circulating optimizer activity. Add an auxiliary two-cycle diagnostic to an optimizer or recurrent training loop: one cycle represents net loss-improving motion, while another represents momentum or noise circulation that can remain active even when the net parameter update is nearly zero. Penalize or throttle this hidden circulation to prevent apparent convergence from masking high update variance and…

Partition a neural network into coupled parameter or activation blocks with distinct effective noise temperatures, and inject Gaussian perturbations whose covariance contains off-diagonal terms induced by the coupling. Unlike standard independent gradient noise, equal-temperature or detached blocks should have negligible cross-correlation, whereas unequal-temperature coupled blocks should exhibit measurable correlated fluctuations.

Regularize hidden-state trajectories so that their temporal statistics match the moments of an isotropic Haar-distributed state up to order k, while deliberately leaving moments above k unconstrained. Use k as a controllable mixing knob: k=1 or 2 suppresses drift and anisotropic variance, whereas larger k imposes stronger distributional invariance and may remove useful temporal information.

Replace the fixed decay coefficient of a stochastic recurrent or state-space layer by an adaptive mean-reversion coefficient driven by the cumulative squared hidden-state energy.

For a neural ODE or physics-informed neural network whose residual cancellation is reliable only after temporal averaging, add an analytic temporal corrector that integrates the zero-mean part of the residual over each time cell. The corrector vanishes at cell boundaries and is smaller by a factor of the cell duration, so it improves pointwise-in-time residuals without changing the learned state at synchronization times.

Replace a time-homogeneous recurrent update by a sequence of parameterized maps f_t, and regularize late-time pairs of updates to approximately commute: applying block f_t followed by f_r should agree with applying f_r followed by f_t. This should make long-horizon predictions robust to local time-step reorderings and schedule perturbations, while proximal statistics provide a diagnostic for whether trajectories repeatedly approach one another rather than diverging permanently.

Replace or augment the transition map of a recurrent state-space model with bounded analytic maps of a latent complex coordinate, using several finite Blaschke generators that share a fixed point. Enforcing a superattracting fixed point of local degree p creates a tunable hierarchy of memory erasure: the theory predicts double-exponential decorrelation with exponent log p, while a merely attracting fixed point gives ordinary exponential decay.
