Train a neural finite-time Hamiltonian-style path from an easy base density to a Boltzmann target by minimizing its generalized nonequilibrium work. The work is a path-space log-density ratio, so its mean is a forward KL divergence up to a constant and the endpoint marginal mismatch is bounded by the same quantity. Unlike an uncorrected neural sampler, this produces a global proposal whose bias and overlap can be measured quantitatively.

Replace ordinary momentum-like accumulation with a PI controller whose integral state is reset when the proportional error changes sign, indicating that the trajectory has crossed its local target. Apply the mechanism to each parameter block or to a scalar block residual, and impose a dwell time so that minibatch noise cannot trigger arbitrarily frequent resets.

Use the paper's random fixed-point attractor and associated Poisson-kernel invariant density as an explicit distributional target for an ensemble of recurrent latent states. Instead of forcing hidden states toward zero, estimate the attractor induced by the recent random map sequence and regularize the ensemble toward its analytically specified angular density.

Add a learned phase coordinate to an RNN, state-space model, or latent neural ODE and train it to advance at constant angular velocity along recurrent trajectories. This separates genuine phase progression from amplitude and embedding distortions, encouraging coherent long-horizon oscillations while providing a quantitative monitor for impending loss of a limit cycle.

Replace unconditional stochastic MGDA in a multi-task network with a regularity-gated update. Compute the conflict-avoidant simplex combination when the objective-gradient geometry is sufficiently regular, but use a fixed scalarization weight when the MGDA solution is near a degenerate simplex face or changes sharply between mini-batches. The gate targets the paper's distinction between 1/2-Hölder behavior in the worst case and Lipschitz behavior on regular subproblems.

Turn a path-complete graph into a stability regularizer for a recurrent or state-space neural network whose update can switch among M learned operators. Maintain a neural quadratic or positive scalar certificate V_alpha for each graph node and penalize every graph edge that violates contraction under its corresponding operator. The resulting architecture is designed to remain stable even when the mode sequence is arbitrary rather than generated by a trained gate.

Use the family predictor not only as a post-processing estimator but also as a feedback controller for data collection. Reweight Monte Carlo proposals or minibatch selection toward under-sampled families whose signed contribution and predictive uncertainty are large, rather than spending samples on already well-known positive families.

Equip each neural-network expert or robot with a locally calibrated e-value for every candidate label, then fuse neighboring e-values using uncertainty-attenuated convex weights. At inference time, retain all labels whose fused e-value does not cross the finite-sample rejection threshold, so the model abstains instead of making an unsupported point prediction. This transfers the paper's coverage-recovery mechanism to ensembles, federated models, and graph neural networks.

Fine-tune a denoiser by matching its action to a target-domain proximal operator, instead of minimizing only pixelwise denoising error. Apply the loss on the intermediate states and noise levels actually encountered by the downstream iterative solver, so the adaptation directly reduces the error that controls PnP reconstruction stability.

Use the observer contraction rate as an online inference controller. Run the latent observer when its estimated contraction is strong, and invoke expensive retrieval or latent-state reinitialization only when contraction is weak or observation residuals indicate model mismatch.

Augment an RNN or state-space model with a region-valued latent state, such as an ellipsoid or polytope, rather than propagating only a point estimate. Train every transition to map the successor region inside the predecessor-compatible region with a positive margin; this creates a neural version of the paper’s nested coder and makes long-horizon predictions robust to small parameter and input perturbations. A point prediction is decoded from the intersection of the propagated regions, while…

Train a conditional flow-matching model against a sequence of intermediate states generated by an expensive optimisation or refinement process, rather than only matching noise to the final sample. The resulting vector field should require fewer inference steps and remain closer to the solver's feasible trajectory than endpoint-only flow matching.

Replace the naive sample variance of correlated rollout returns with a recursive variance target attached to every state-action node or latent rollout node. The target separates uncertainty caused by immediate reward noise, stochastic next-state selection, and uncertainty already present in child value estimates, enabling calibrated heteroscedastic Bellman updates and uncertainty-aware rollout allocation.

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.

Replace a linear restoring drift in score-based sampling, latent dynamics, or stochastic regularization with a state-dependent nonlinear restoring term that is at least as contractive globally and more contractive away from the origin.

Use held-out calibration trajectories to convert decoded latent-filter residuals into distribution-free error thresholds.

Replace a fixed temperature schedule in a population-based, derivative-free neural-network optimizer with a feedback controller driven by the entropy of candidate importance weights. When candidate losses are diffuse, the optimizer cools rapidly to exploit progress; when one or a few candidates dominate, cooling slows to prevent irreversible population collapse and loss of exploration.

Build a complex-valued coordinate map q(x) whose components are harmonic and whose gradients are mutually null, then feed q(x) into an otherwise unconstrained neural function v. Any learned output of the form u(x)=v(q(x)) is analytically harmonic when the constraints are satisfied, so the network does not need to rediscover the Laplace structure from collocation data. This is especially suitable for two-dimensional elliptic PDEs, where q=x+iy is the canonical example.

Replace an unconstrained recurrent block with two coupled modules: a contractive perceptual estimator and an input-to-state-stable cognitive state transition.

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.
