Spectral-gap adaptive halting

Use the local Jacobian of a looped transformer to estimate its remaining relaxation time and stop the recurrent computation when the predicted residual reduction is sufficient. Near a saddle-node fold, the paper's asymptotic relation converts an estimated dominant eigenvalue into a compute forecast, allowing dynamic iteration budgets instead of a conservative fixed maximum.

Certified Temporal Budget for Neural Control

Attach a learned controller to a physical or simulated plant and use a continuous safety certificate to compute a conservative remaining-time budget before the current action or latent prediction can become unsafe. Compile this spatial margin into a unit-rate temporal contract, allowing asynchronous inference, batching, or early execution without online rollout integration; trigger a new network evaluation only when the countdown reaches a guard threshold.

Safe Receding-Horizon Neural Topology Switching

Treat a change in a neural network mask, expert set, layer width, or adapter configuration as an optimal transition problem rather than an instantaneous switch. A cheap planner proposes a short sequence of topology masks and parameter interpolations, while an expensive forward-pass feasibility filter rejects each candidate intermediate model if it violates accuracy, activation, norm, latency, or memory limits. This permits dynamic pruning and MoE reconfiguration with a certificate that the…

Lipschitz-Certified Cache Refresh

Attach a certificate to a cached transformer KV state or recurrent latent state and refresh it only while its predicted certificate remains inside a latency-contracted admissible region. The controller uses a bound on certificate drift to guarantee that the state will remain admissible throughout the next sampling, communication, and execution delay, reducing unnecessary recomputation while exposing a measurable refresh boundary.

Fading-Memory Habituation Gate

Add a per-feature or per-token state that accumulates recent stimulation and decays when stimulation is absent, then use a nonlinear decreasing gain to suppress repeatedly activated features. This creates short-term adaptation without changing the core transformer or recurrent weights: familiar inputs are processed with reduced gain, while novel inputs recover their full response.

LQ-Compressed LPV Latent Rollouts

Replace a neural sequence model's unconstrained multi-step latent rollout with a data-driven LPV predictor acting on a learned latent state. Build the predictor from Hankel matrices of past latent observations, inputs, and scheduling features, then use an LQ factorization to project the large data coefficient matrix into a fixed-dimensional coordinate system. The model preserves scheduling-conditioned dynamics while making rollout cost independent of the number of training trajectories.

Phase-controlled Jacobian training

Add a local Jacobian spectral regularizer and an initialization sweep to steer a looped transformer away from uncontrolled near-unit dynamics. The goal is to prevent examples from entering a fold-critical regime with very long relaxation times, or alternatively to deliberately target a controlled critical regime when adaptive test-time compute is useful.

Zeno-Free Minkowski Routing

Represent adaptive computation or MoE routing as a continuous latent trajectory that crosses convex mode walls, with a Minkowski norm defining computational speed. At a wall, choose the outgoing latent velocity by the same constrained variational rule as billiard reflection, and use the local path-length certificate to detect or prevent pathological accumulation of infinitely many routing events in finite depth.

One-Shot Frozen Refinement Layer

Add an asynchronous binary refinement module in which each spatial unit or graph node may change its predicted label once if its current label disagrees with a weighted neighborhood field, after which it is permanently frozen. This prevents recurrent flip-flopping in iterative segmentation or denoising and should preserve large-scale structures while allowing a final interface-localized correction phase.

Hitting-Time Adaptive Transformer Depth

Use attention-graph hitting times to identify tokens whose information has not mixed through the network, then route only those tokens through additional Transformer blocks. Tokens with fast reachability exit early, while slow or isolated tokens receive more computation.

Two-chart refinement cell

Build a recurrent ReLU module that evaluates a binary refinement cascade using a fixed-dimensional state and shared cell weights. Replace hard binary digit selection with two overlapping circle coordinates; switch between their affine state updates only at points where the two candidate updates agree, so the switch is an exact continuous piecewise-linear ReLU operation rather than a multiplicative gate.

Finite-Orbit Circulant State Core

Replace the linear state transition in a small recurrent or state-space module by a circulant matrix acting on a vector over a finite field. The hidden state then has only finitely many possible values and follows an exactly periodic orbit after at most \(q^n\) states, eliminating numerical drift on modular-counting and symbolic-memory tasks. A learned real-valued encoder and decoder can surround the discrete core, while the transition itself is fixed, searched, or trained with a…

Gramian-balanced neural SSM compression

Compress the hidden state of a stable neural state-space layer using low-rank controllability and observability Gramians. States that are difficult to excite from the input or weakly visible at the output are removed, producing a smaller recurrent state with a principled input-output preservation criterion.

WKB-Stokes Sparse Mixer

Replace a dense channel-mixing matrix in a sequence layer with alternating diagonal propagation and sparse unipotent Stokes jumps. The diagonal part carries independently controlled exponential phases, while the unipotent factors implement cheap residual-like mode conversion without changing determinant or requiring a dense matrix multiply. Constrain the phase magnitudes and jump coefficients during training to obtain a reversible, norm-monitorable mixer.

Polynomial Spectral Mode Controller

Replace an eigendecomposition-based spectral controller in a small recurrent or state-space transition layer with explicit polynomial projectors. Each hidden state is split into invariant modes, and each mode receives a separately constrained recurrent multiplier, enabling direct suppression of unstable modes or selective retention of long-memory modes using only matrix-polynomial evaluations.
