Replace raw control-barrier-function value penalties with an invariance-authority demand computed from boundary geometry and available control authority. For a learned or known control-affine neural dynamical system, penalize states where the uncontrolled vector field points outward more strongly than the actuator can push inward. The resulting quantity is invariant to positive rescaling of the barrier representation and directly predicts the actuator-strength threshold at which controlled…

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.

Approximate the minibatch loss Hessian by a positive-semidefinite bulk curvature plus a small signed transverse correction, and treat only the correction with explicit negative-curvature steps. This imports the paper's observation that all unstable directions can be confined to a low-dimensional subspace, producing a curvature-aware optimizer whose step-size boundary is governed by a small matrix rather than the full Hessian.

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.

Construct a neural acceptance or abstention set from calibration samples together with an explicit boundary map selecting the samples that determine the set. If the map is proper projective and its cross-sample complexity profile is stable, the conditional violation risk has an exact beta law indexed by boundary size rather than network parameter count. This provides a falsifiable, distribution-free certificate for neural selective classifiers and learned safety filters.

Estimate the largest certified input perturbation radius for a neural network using nested reduced primal and dual linear programs rather than solving the complete verification LP immediately. The primal sequence gives certified feasible robustness reserves, while the dual sequence gives valid upper bounds; verification may stop as soon as the interval width is below a prescribed tolerance.

Represent a learned optimizer or recurrent training controller as a discrete-time feedback system and certify its sensitivity to one-sample dataset replacement using an IQC dissipativity inequality. Penalize the smallest certified disturbance-to-state gain during meta-training or use it as a post-training acceptance test, favoring update dynamics that do not amplify microscopic data perturbations over many iterations.

Train a neural barrier function that certifies a lower bound on the probability of reaching a target before entering an unsafe set, uniformly over an entire compact set of initial states. Add boundary and expected-drift penalties to a learned world model or policy, and enforce a positive slack margin rather than fitting only pointwise trajectories. The mechanism should improve safety under distribution shift because the certificate constrains one-step stochastic transitions throughout the…

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.

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.

Replace an unconstrained scalar MLP certificate with an anchored positive-definite network whose value and gradient are fixed at the equilibrium. Train it so that its Lie derivative along a neural or physical vector field is strictly negative on a prescribed region of attraction. The construction makes stability robust to approximation error: a certificate remains valid whenever the value, gradient, and Lie-derivative errors stay below the target's strict-decrease margin.

Treat a neural-network training update as a control input and impose control-barrier inequalities on quantities that must remain safe, such as parameter norm, activation variance, attention-logit magnitude, or an estimated Lipschitz margin. At each step, solve a small quadratic program that stays as close as possible to the nominal gradient update while guaranteeing a first-order forward-invariance condition.

Represent a scalar energy or free-energy functional of a three-dimensional neural field using translation- and rotation-equivariant convolutions, and produce the field prediction by minimizing the total functional rather than by a direct decoder. The same functional can then generate equilibrium states, forces, and response observables under new external fields, resolutions, and system sizes.

Train and select neural ODE architectures using parameter sensitivities and Fisher information, so that a model is penalized or rejected when different parameters produce nearly indistinguishable trajectory effects. The neural component remains inside the ODE vector field, but its width, depth, and parameterization are selected using predictive error together with the smallest Fisher-information eigenvalue, effective rank, and confidence intervals.

Evaluate a neural network’s learned state by comparing its normal future-task performance with a matched blind counterfactual in which the stored representation, adapter, optimizer state, or memory slots are inaccessible and the model must re-optimize from the same compute budget.

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.

Augment a latent neural state-space model with an observable-coordinate residual that is first learned flexibly and then projected onto a constrained library of interpretable coupling terms. Train or collect data only after checking that the trajectory sufficiently excites the candidate terms; this prevents a latent model from fitting arbitrary hidden-state effects that are unidentifiable from the observations.

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.
