Use farthest-triplet entropy as a low-bandwidth observable of whether a hyperbolic embedding is angular- or radial-dominated, then adapt the hyperbolic curvature rather than fixing it arbitrarily. In the isotropic shell regime, invert the entropy-to-signal curve to estimate the effective radial/angular parameter and select curvature that reaches a chosen geometric operating point.

Use several phase-locked states as distinct attractors of one recurrent network and shape their basin asymmetry through the phase-delay composite spectrum. This creates a controllable associative-memory architecture in which a desired memory receives a larger basin without adding a separate classifier or explicit nearest-neighbor lookup.

Replace an unconstrained continuous-depth neural update with a constrained implicit Runge–Kutta step whose internal stages and final state are required to remain in a convex feasible set. For box-constrained latent states, this prevents exploding or negative states while retaining the high-order structure of Radau or Gauss integration and avoiding the order-destroying behavior of post-step clipping.

Train a recurrent neural network or state-space model using a Poincare-style event loss: identify two consecutive latent alignment events and require the latent position and velocity at the second event to equal a transformed version of the first. Evaluate the Jacobian of this return map and penalize unstable non-neutral Floquet multipliers, producing long-horizon trajectories that are both periodic or symmetry-periodic and locally stable.

Replace a fixed gradient-clipping threshold or fixed optimizer trust region by a dynamic envelope that expands when proposed parameter updates are repeatedly clipped, contracts after clipping disappears, and tightens further during sustained unsaturated convergence. This transfers the paper's bidirectional modification mechanism to training while retaining an explicit safety cap on the actual parameter update.

Use a spectral eigenvalue-counting function to bracket each target mode before neural optimization. The network then solves only within an interval containing exactly one eigenfrequency, preventing optimization from repeatedly collapsing to the lowest mode or jumping between modes.

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…

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.

Turn a latent recurrent model into an observer that continuously corrects its hidden state from noisy or partial observations while certifying both estimation-error convergence and disturbance attenuation. The bounded-real operator inequality becomes a trainable regularizer for a neural correction gain, providing a principled alternative to unconstrained teacher forcing or ad hoc residual correction.

Replace an unconstrained recurrent transition by a ring-coupled cubic vector field whose radial component drives hidden states toward a prescribed sphere.

Train decentralized agents using only individual rewards for discovering replenishable targets, while their observations contain conspecifics but not target locations. Give the policy a tunable visual or attention radius and test whether aggregation and improved search emerge above the predicted crossover, without adding alignment, proximity, or group rewards. This creates a controllable collective phase that can reduce redundant exploration and improve multi-agent resource discovery.

Build a neural operator from frozen ambient mechanism blocks and a geometry-specific algebraic constraint adapter. The adapter parameterizes all outputs in the affine set satisfying sampled linear constraints exactly, so the network never produces boundary-violating states and does not require a penalty coefficient or post-step projection.

Add an observer correction to a recurrent or state-space neural model and constrain its local dynamics so latent-state errors contract according to a quadratic Lyapunov certificate. The design tolerates nonlinear residuals that are not globally Lipschitz, provided their one-sided growth and quadratic inner-bound constants satisfy a computable matrix inequality.

Add a low-dimensional feedback correction to the neural reference so that accumulated position mismatch is removed when actuator saturation or kinematic mismatch causes the shaped trajectory to lag the requested one. Unlike ordinary integral action, the correction is passed through the same feasibility-preserving reference shaper, preventing integral windup while ensuring that compensation cannot violate current, voltage, speed, or acceleration limits.

Build a recurrent module from two finite-state factors: a normalization state and a winner-selection state. Choose or learn their coupling so that the joint transition system contains a certified composite two-cycle, giving the network a small robust memory state, while every fixed-input generator still collapses most states toward attractors. The module can be embedded in a continuous RNN using soft state assignments during training and straight-through discretization for algebraic auditing.

Use a cyclic forward-neighbor recurrent or state-space layer and regularize its coupling so selected discrete Fourier modes are contracting while task-critical modes remain weakly damped.

Construct a recurrent layer whose hidden states evolve as directed phase oscillators with a prescribed nonzero common frequency and fixed phase offsets.

Partition a neural network into interacting modules and constrain the product of their local finite-region gains and coupling strengths so that the resulting gain matrix has spectral radius below one. This transfers the paper's small-gain-like mechanism and gives a quantitative large-signal boundary: instability or exploding activations should emerge as the spectral radius approaches one, while a weighted Lyapunov function should contract below that boundary.

Modify an L-BFGS curvature pair only when the observed secant curvature is negative. Replace the gradient-difference vector by the smallest Euclidean or inverse-metric correction that enforces positive curvature, then use the unmodified BFGS update and two-loop recursion.

Use the random-attractor construction as a training and inference diagnostic: initialize latent trajectories far in the past with different states but the same recent noise sequence, then measure whether they contract toward the same current set.

Replace an unconstrained recurrent or state-space update with a delayed continuous-time hidden-state block and constrain its local closed-loop Jacobian using an output-to-output dissipativity LMI. The certificate bounds amplification from external perturbations, such as corrupted observations, injected hidden-state noise, or delayed-input errors, to the task output. Training rejects or penalizes parameter updates for which the certified gain becomes too large.
