Represent the propagation of hidden states, layer states, or optimizer states by a locally estimated transfer operator and monitor its leading eigenvalue gap. When two dominant modes undergo an avoided crossing, reduce the update scale or increase damping; after the gap reopens, restore the normal schedule. This imports the paper's sharp-but-continuous pseudo-transition mechanism rather than treating instability as a binary divergence event.

Track a symmetry-asymmetry functional of network outputs or hidden states under a chosen transformation or channel and estimate which relaxation modes control its late-time decay. Use a short warm-up trajectory to suppress the slow asymmetry mode while allowing larger initial asymmetry in faster modes, producing a training trajectory that can overtake a nominally better-initialized trajectory. This transfers the paper's quantum Mpemba effect as a mode-overlap principle rather than requiring an…

Replace the usual parameter-plus-momentum Langevin state with a three-level chain consisting of parameters, velocity, and acceleration, while injecting Gaussian noise only into the highest auxiliary state. At a saddle, the escaping direction has a positive rate given by a cubic characteristic equation; use this rate to choose damping or adapt the temperature so that basin escape is accelerated without making the dynamics unstable.

Construct a robust covariance estimate of layer activations by replacing each feature with its empirical Gaussian normal score before eigendecomposition, then applying coordinate-wise nonlinear eigenvalue shrinkage rather than multiplying all eigenvalues by one scalar. Use the cleaned covariance to whiten activations or precondition updates to the associated linear layer. This targets unstable directions caused by small batches, heavy-tailed activations, and rare outliers while retaining…

Replace ordinary graph propagation by diffusion with a positive node-dependent mass matrix \(\mathbf V\), so high-volume nodes update slowly and low-volume nodes update rapidly. Use node volumes as fixed metadata, a function of degree, or learned positive gates; this makes the architecture sensitive to dynamical localization that degree-normalized GCNs cannot represent.

Train a recurrent or state-space network together with a periodic hidden-state trajectory, then use the Fourier-domain Hill operator of its linearized dynamics to penalize positive Floquet growth rates. The method can retain algebraic hidden-state constraints, avoiding the inaccurate practice of treating a singular descriptor matrix as invertible.

Replace a stationary optimizer by a periodic two- or multi-phase schedule, such as alternating large and small learning rates, SGD and momentum, or gradients from different loss components. Stability is assessed over the complete period using the product of phase-wise linearized update maps, allowing a phase that is individually expansive to be safely combined with a contracting phase.

Use the q-fractional characteristic equation as an online trust-region controller for recurrent gain or residual-memory strength.

Treat parameter-space curvature modes as RG momentum shells and use a smooth cutoff to construct a scale-dependent preconditioner rather than abruptly clipping eigenmodes. The optimizer should expose measurable crossovers between overdamped, KPZ-like, and nearly inviscid relaxation, allowing the learning rate and damping to change at empirically detected transitions instead of following a fixed schedule.

Build a delayed recurrent layer whose state update contains explicit taps at lags k tau, and monitor whether its linearized dynamics support periodic or antiperiodic modes over a window of length m tau. Use the smallest singular value of the corresponding periodic-boundary residual as a bifurcation margin: values near zero indicate that a new oscillatory memory mode is being created or destroyed. The margin can be used either as a diagnostic or as a regularizer that keeps training away from…

Replace independent expert activation or ordinary softmax routing with an exact fixed-m external-field subset router. Parameterize expert weights by logits, use the subset covariance as the Fisher matrix, and precondition router gradients with its Moore-Penrose pseudoinverse on the sum-zero subspace. The paper's resistance bound supplies a data-dependent ceiling for pairwise logit updates, preventing unstable motion when some experts have low inclusion variance.

Construct a positive learning-rate schedule offline by minimizing the worst residual of every prefix on a normalized curvature interval, rather than optimizing only the final training horizon. The schedule is evaluated through the exact quadratic residual polynomial p_n(lambda) = product_{k=1}^n (1 - eta_k lambda), so every prefix is constrained to make progress across multiple curvatures.

Use Adam normally, but periodically estimate the spectrum of the Adam-preconditioned Hessian and add a damped low-rank Newton correction when the preconditioned curvature is strongly ill-conditioned or the gradient is concentrated in flat directions. The correction is computed only in a small Lanczos subspace, so the method targets cross-coupled ill-conditioning without materializing or inverting the full Hessian.

Split the optimizer state into a passive descent sector and an explicitly nonequilibrium current-like sector, then constrain the local update Jacobian to be block triangular.

Apply an inverse-square Calogero barrier to the eigenvalues of a recurrent or state-space transition Jacobian, discouraging unstable eigenvalues and pathological eigenvalue collisions without forcing the matrix to be Hermitian. The paper's non-Hermitian scattering picture motivates treating the spectrum as correlated rather than assuming an ordinary pairwise Coulomb gas; the inverse-square term is used as a local, computable surrogate for that mechanism.
