Miner-State Monotone Prognostics

Add an explicit cumulative damage state to a neural sequence model and penalize predictions whose degradation estimate decreases as this state increases. This transfers the paper's separation of physics-informed history encoding and monotonicity regularization to battery-health prediction, remaining-useful-life estimation, thermal aging, and other nonstationary sequence problems.

Information-Gated Attention

Use predicted covariance reduction as a differentiable gate for selecting tokens, views, sensors, or retrieved demonstrations. The gate favors inputs with high expected information gain while accounting for acquisition cost, turning attention and data collection into active observability optimization.

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.

Smooth Barrier Tube Controller

Treat undesirable neural-network states as obstacles and steer training or inference away from them with a smooth distance barrier while preserving a nominal loss descent direction. The barrier can protect against exploding activations, excessive attention concentration, unsafe controller outputs, or leaving a certified representation region without introducing discontinuous gradient clipping.

BDD-Certified Modular Equilibrium Network

Partition a neural network into N interacting modules and constrain the Jacobian of its implicit residual map to be block diagonally dominant. Each module can compute its update locally while cross-module coupling is monitored through a normalized block-row margin. The certificate guarantees local nonsingularity of the equilibrium equations and predicts a sharp loss of robustness when the largest BDD ratio approaches one.

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.

Lyapunov-Calibrated Multiplicative Noise

Use measured local Jacobian growth to set the variance of dropout, feature noise, or stochastic-depth perturbations, implementing the paper's fluctuation-response idea that multiplicative noise is tied to the positive scrambling or Lyapunov rate. The controller maintains a target growth regime instead of applying a fixed noise schedule throughout training. It predicts a stability transition when the estimated growth rate crosses zero and a variance-growth proportionality that can be tested…

Gain-Weighted Cluster Co-Design

Use small-gain diagnostics to jointly learn module normalization and a communication partition rather than imposing a fixed global spectral constraint. Clusters should be formed around high-gain feedback loops, because grouping weakly related modules cannot improve the certificate and only adds bookkeeping.

Control-Cost Laguerre MoE Routing

Route tokens to experts using Laguerre cells defined by the minimum control energy needed to move a token embedding to each expert prototype, rather than by Euclidean distance or an unconstrained learned router logit. Per-expert dual weights deform the cells so that minibatch routing follows prescribed expert capacities, giving a geometrically interpretable alternative to auxiliary load-balancing losses.

Predictive Zonotope Compression for Certified Neural Inference

Propagate uncertain inputs or parameter perturbations through a neural network with zonotopes, and choose the reduction rule after each layer using short lookahead that predicts downstream certified-bound error. Candidate reducers can include largest-generator retention, box conversion, and norm-based merging; unlike a fixed policy, the chosen rule depends on the current generator geometry and remaining network depth. The goal is tighter robustness bounds at the same generator budget, or the…

Cumulative-Control Surrogate Encoder

Use cumulative control measures as the input to a neural surrogate instead of the full sequence of control values. For a quasi-static free-boundary system satisfying the paper's average-pressure path-independence assumption, two nonnegative control histories with identical integrals up to time t should produce the same state at t, allowing a smaller training input and fewer distinct control trajectories in the dataset.

Schur-Certified Homeostatic Depth Controller

Add a small dynamical state on the transformer module graph and use it to control adaptive computation, but reject controller parameters whose discrete-time update has latent roots outside the unit disk. The state can modulate halting thresholds, residual-block gains, and memory gates; the certificate applies to the controller integrator and prevents unstable oscillations or exploding internal control signals during long adaptive-depth rollouts.

Subcritical Gradient-Cascade Control

Treat a small activation, gradient, or parameter perturbation as a seed and measure the number of newly affected downstream units or layers. Use the estimated branching ratio to control the optimizer step size or residual gains, keeping training in a subcritical regime where perturbation cascades have finite expected size instead of amplifying through the whole network.

Forward-Invariant Expert Authority Router

Replace unconstrained or entropy-regularized MoE routing with a minimally disruptive update that preserves a lower bound on the log-determinant of the experts' weighted output span. The router still tracks the desired mixture, but a projection prevents the active experts from becoming linearly redundant or collapsing onto a low-rank subset.

Boundary-Hankel Mediator Regularization

Treat a selected neural submodule as an open dynamical system embedded in the rest of the network. Regularize it to contain internal modes that are simultaneously reachable from many external features and observable through many external outputs, rather than behaving as a one-sided receiver, broadcaster, or disconnected read/write split.

Cactus-Graph Phase Budgeting

Build neural computation graphs with explicitly phase-budgeted serial and parallel branches, treating serial compositions as SRG products and parallel residual branches as SRG sums. Allocate phase centers theta_i so that every loop or branch aggregate stays away from -1, enabling stability-aware architecture search and constructive control of branch gains.

Oja Gradient-Subspace Optimizer

Track the dominant rank-r subspace of the gradient covariance online, then use that basis to construct a low-rank adaptive update or a controlled preconditioner. Unlike offline PCA refreshes, the Oja flow continuously follows changing training geometry while preserving orthonormality, potentially reducing the cost of second-order or Shampoo-like methods.

Lyapunov Sign-Search Optimizer

Wrap a nominal gradient-based optimizer with a diagonal sign matrix that flips updates independently for parameter blocks, while a scheduler tests candidate sign configurations using short-horizon decrease of a Lyapunov-like training energy. The wrapper never changes the magnitude of the nominal update, and when the effective sign pattern is constant, it should recover the behavior of the correctly oriented nominal optimizer after a finite search period.

Blow-Up Annealing for Heterogeneous Sharpness

Assign separate sharpness or temperature parameters to two nonlinear subnetworks and anneal them according to a directional chart instead of driving both to their singular limits at the same rate. The optimizer explicitly tracks the ratio of the two scales and changes the schedule when the local Jacobian approaches a stability or bifurcation boundary. This tests whether the order and relative rate of sharpening, rather than only the final activation shape, controls optimization stability and…
