Dissipative Neural State-Space Identification

Attach a learned nonnegative storage function to a neural state-space model and penalize violations of a strict dissipativity inequality during rollout training. The resulting telescoping inequality limits cumulative output deviation and provides a monitor for whether long-horizon simulations are entering a stable turnpike regime.

Conley-Certified Latent World Model

Train an encoder-decoder world model together with a latent transition map, but certify latent attractors only when the learned model is approximately semiconjugate to the observed high-dimensional dynamics with residual below the isolating-set margin. Compute a Conley-Morse graph on a latent grid and lift each certified recurrent component through the decoder to obtain a region in the original state space where an attractor or invariant set is predicted to exist.

Fixed-Time Riemannian Barrier Optimizer

Train network parameters on a constrained Riemannian manifold using a loss-plus-barrier potential and a two-power normalized gradient flow. The sublinear term rapidly removes optimization errors near the target, while the superlinear term prevents arbitrarily slow convergence from distant initializations; the barrier keeps iterates inside a prescribed feasible region.

ESS-Aware Byzantine Gradient Fusion

Replace independent-client assumptions in federated learning with a dynamical estimate of conformity-amplified client corruption. Track the fraction of honest clients that have adopted a misleading update direction, predict its equilibrium using a bounded-rational conformity model, and use that effective error probability in a MAP estimator for the global gradient or class label.

Lyapunov-Certified Policy Training

Train a neural policy together with a positive neural Lyapunov function so that the learned closed-loop transition decreases the function at every sampled state in a prescribed operating region. This converts policy learning from an unconstrained reward problem into a constrained dissipativity problem and provides an inference-time monitor that can reject or damp actions when the certificate is violated.

Adaptive SOS Lyapunov Certificate Ladder

Represent a small neural state-update map or optimizer update by polynomial constraints and certify decrease of a polynomial Lyapunov function on the nonnegative activation or state region using successive Parrilo SOS levels. Use the monotone shift-threshold construction to distinguish genuine instability from failure of a weak certificate, and raise the SOS level only when necessary.

Reference-Preserving Martingale Layer

Replace an unconstrained stochastic transition between categorical or discretized latent distributions by a transition matrix that preserves a prescribed reference distribution while mapping relative populations through a martingale. This prevents the layer from inventing arbitrarily sharp deviations from the reference and imposes a convex-order monotonicity condition on uncertainty across layers or diffusion time steps.

Shared-Observation Collective Shield

For z neural branches that share a target, state, or routing observation, add a penalty on fluctuations in the branch direction visible to that shared signal. This implements the paper's centered-square conditioning mechanism: branches remain locally independent in hidden directions, while collective deviations that would produce inconsistent shared outputs are suppressed.

Conservative Density-Functional Network

Predict a scalar excess free-energy functional of a complete density field and obtain the direct-correlation output by automatic differentiation, instead of independently predicting each output-site value. This enforces the integrability and reciprocity constraints of a thermodynamic force field and gives a Lyapunov-like scalar that can control iterative density inference.

Multi-source conditional OT adversarial training

Replace ordinary empirical-risk minimization on pooled heterogeneous data with worst-case conditional risk over joint distributions that remain close to every source under an optimal-transport budget. The adversary transports source context-label pairs toward high-loss, target-event-like examples, while source-specific radii prevent arbitrary shifts. This should improve performance on rare target contexts and unseen domains without requiring abundant target labels.

Lyapunov-Margin Noise Scaling

Treat stochastic optimization as a perturbed stochastic dynamical system and adapt the magnitude of gradient noise, minibatch error, or parameter perturbations using an estimated Lyapunov decay margin. Perturbations may remain larger far from a solution, but their allowed magnitude is reduced when the local stability margin becomes small, implementing the paper's state-dependent robustness and stochastic input-to-state stability mechanism.

Conditional-information-preserving pooling

Replace ordinary token merging or graph pooling with a learned block map whose output preserves information about a remote target conditioned on the surrounding coarse representation. The paper's majority-spin counterexample gives a concrete failure mode: two microscopic configurations mapped to the same pooled token can imply different predictions for distant variables.

Krylov Resonance Regularization

Add a resonance-estimation module to a recurrent network or state-space model and regularize the decay spectrum of its observable correlations. Instead of using eigenvalues of a small projected recurrent matrix as memory timescales, estimate dominant poles from multi-step correlations and a resolvent/Krylov fit, thereby remaining valid when projection eigenvalues are ill-conditioned or hidden resonances occur. The method is intended to preserve useful long memory while suppressing unstable or…

Eigenmode-Targeted Hidden-State Actuator Selection

Treat a recurrent or state-space network as a locally linear dynamical system and select a small set of hidden-state or module coordinates that have unusually high leverage on a target output through a dominant unstable or weakly damped eigenmode. Use the ranking both for red-team targeted perturbations and for defense: penalize, prune, or damp selected coordinates so that target amplification is reduced without uniformly shrinking all recurrent dynamics.

Robust Lyapunov Training Under Model Error

Require Lyapunov decrease not only under the nominal learned transition, but throughout a bounded uncertainty set around that transition. The policy is therefore optimized against identification error and distribution shift rather than trusting a potentially overconfident world model.

Bounded Telegraph Exploration for Optimizers

Add a bounded colored exploration force to an optimizer by filtering a sum of independent two-state telegraph signals through a stable linear relaxation equation. Unlike Gaussian momentum noise, the perturbation has a strict amplitude bound and a tunable finite correlation time, reducing rare destructive parameter excursions while retaining structured exploration.

Inverse-Square Adaptive Parameter Reset

Add a state-dependent stochastic reset to a neural-network parameter vector, optimizer state, or recurrent hidden state. The reset hazard is weak at large displacement but has the marginal inverse-square scaling that produces a predicted power-law excursion distribution and a sharp transition between localized training and runaway parameter drift.

Spherical harmonic spectrum regularizer

Constrain a set of learnable or batch-produced unit-norm embeddings by matching their spherical-harmonic power spectrum to a target spectrum rather than relying only on pairwise Euclidean repulsion. This creates an explicit, tunable mechanism for suppressing low-frequency density fluctuations or enhancing a selected angular frequency, which can improve uniformity and reduce representation collapse on hyperspherical embeddings.

Use the Aitchison distance on the content composition, which compares relative token allocation and prevents a large common sink probability from overwhelming differences between content tokens.

Compare nominal trajectories with perturbed pseudo-trajectories under reparametrizations whose secant slopes lie in [1-epsilon,1+epsilon], and penalize failures of a single near-identity time map to track the perturbed path.
