Train a neural state-space model using all replayed transitions, but assign larger weights to samples near the current operating context rather than discarding distant samples. Add a strictly positive weight floor so local adaptation cannot eliminate global coverage or make the regression problem rank-deficient. This should improve prediction across nonlinear regimes while retaining the numerical robustness of full-data training.

Equip a neural policy or learned world model with an MPPI-style rollout planner whose perturbation covariance is conditioned on a discretized latent-state cell and updated from observed transition residuals. Apply spatial diffusion to neighboring covariance estimates using a kernel matched to the empirical visitation distribution, so covariance adaptation is smoothing rather than an unstable independent estimate at every state.

Make a diffusion policy or MPPI-style action-sequence sampler less committed to model-predicted cost rankings when the learned world model is inaccurate. Estimate a normalized prediction residual or ensemble disagreement, increase the sampling temperature with that residual, and retain ordinary low-temperature exploitation when the model is accurate.

Separate a pretrained sequence model's passive prediction from the causal effect of an action, and learn only the latter with a compact monotone adapter. The adapter receives the current latent state and an action deviation, but its action-to-output Jacobian is constrained to have the physically correct sign, preventing intervention predictions that move opposite to the applied control.

Attach a finite-state monitor to a neural policy and allow only actions whose successor remains in the simultaneous backward-reachable winning set for all active modes. Modes may encode safety, hardware configuration, and independent task goals. This gives a hard runtime constraint rather than relying on a reward penalty to teach the policy not to enter irreversible dead ends.

Add a safety projection step to every or selected Euler updates of a flow-matching action sampler. Instead of correcting only the first action, differentiate a collision-risk function through the predicted full action chunk, construct local linear inequality constraints, and apply the smallest correction that makes the future trajectory safe.

Attach a sampling-based rollout correction head to a neural policy or learned world model, and adapt its temperature and number of rollouts so that approximation error stays within the contraction margin of a nominal policy. The controller should spend samples only when the local state-dependent error gain is close to violating the small-gain condition, instead of using a fixed MPPI sample count everywhere.

Train a neural controller as a uniformly accurate surrogate of a trusted but expensive controller, and use a measured small-gain condition to decide whether the surrogate is safe for closed-loop deployment. The approximation tolerance becomes an interpretable residual-state budget instead of an opaque validation metric.

Build a recurrent or state-space model with latent coordinates split into tangent variables that carry the modeled dynamics and transverse variables that contract toward a learned invariant manifold. Penalize violations of invariance and enforce a spectral gap between tangent and transverse Jacobian dynamics, preserving useful noncontracting behavior while suppressing off-manifold drift during long rollouts.

Add a separately identified constant or slowly varying force channel to a neural dynamics model, analogous to the paper's online gravity-trim and mass adaptation. This isolates persistent low-frequency prediction bias from state-dependent dynamics, reducing repeated corrective action by the planner and avoiding expensive network retraining after a systematic shift.

Attach a small, online-adapted Taylor-polynomial residual model to a neural dynamics model instead of adapting all network weights. Construct the dictionary from the local Taylor structure, remove monomials forbidden by known joint-odd symmetry, and update its coefficients with recursive least squares. This yields fast adaptation with an interpretable parameter count and a direct test of whether the assumed symmetry is valid.

Add an explicit memory field to a recurrent or state-space model and make the memory feedback act through a discrete biharmonic operator, producing the paper’s characteristic \(z=4\) long-wavelength relaxation. This should preserve slowly varying sequence structure while damping high-frequency hidden-state noise, potentially improving long-horizon prediction without requiring a very large recurrent state.

Add a pressure-like recurrent state to a neural surface-flow decoder and update it from the predicted local divergence, creating a learned or fixed feedback loop that drives vector outputs toward local incompressibility.

Replace a neural controller's pointwise action outputs over a finite horizon with Bernstein control points whose convex hull satisfies actuator and trajectory constraints.

Replace an explicit recurrent transition with a learned descriptor relation in latent space, allowing some latent coordinates to satisfy algebraic constraints rather than being numerically integrated. Fit the relation using total-least-squares or iterative PCA on the jointly observed trajectory, so noise in every channel is treated symmetrically and the model can discover whether the latent system is index-0 or index-1.

Train a neural state-space model whose one-step dynamics are linear in a fixed analytic feature vector, and use the empirical feature Gram matrix to detect whether passive trajectories identify the dynamics. Add data collection or replay only when the Gram matrix is poorly conditioned; the analytic-feature assumption predicts that persistent excitation should emerge without deliberately visiting every operating mode.

Replace an unconstrained recurrent hidden-state channel with a two-dimensional oscillator constrained to the supercritical Hopf normal form.

Replace online enumeration over a finite action set with a classifier or lookup map whose regions directly return the action minimizing a one-step predictive-control cost. For affine dynamics and quadratic tracking loss, exact action regions are separated by pairwise cost boundaries, so the approximation can be audited against exhaustive predictive control rather than treated as an unconstrained policy.

Split a neural controller into a slow model-based planner and a fast policy instead of requiring either component to perform the entire control task. The MPC output provides a slowly varying nominal action or operating envelope, while the neural policy generates high-frequency residual corrections.
