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…

Confidence-Tested LoRA Pruning

Replace deterministic LoRA importance scores with one-sided tests of whether each rank-one update has population contribution at least a user-selected threshold. Maintain empirical contribution samples during fine-tuning, estimate their uncertainty, and prune the components with the weakest statistical evidence while respecting the target rank budget. The method should avoid deleting components merely because their latest minibatch gradient was small.

Annihilating Density-Transport Feature Mixer

Replace an ordinary local convolution or token-mixing block by two nonnegative feature populations A and B that diffuse and drift along the spatial or token axis, with transport rates increasing quadratically with local population and with an optional directional bias. Add a local A plus B to empty reaction so mutually conflicting feature mass is removed rather than merely averaged. The module should produce adaptive competition, and its isolated relaxation should exhibit a measurable t raised…

Screened Cross-Correlation Regularizer

Impose a screened pair-correlation dynamics on stochastic neural replicas so that correlation fluctuations relax locally instead of propagating across the entire representation. The key control knob is a learned or scheduled relaxation rate \(\mu_{FB}\), which predicts a measurable correlation length \(\xi_{FB}=\sqrt{D_{eff}/\mu_{FB}}\). This can be used as a locality regularizer for token representations, diffusion trajectories, or recurrent hidden states.

Stable-charge attention kernel

Attach each token or graph node a learned scalar charge q_i and add a fractional stable kernel K_ij = exp(-tau D |q_i-q_j|^alpha) to the interaction mechanism. Constrain 0 < alpha <= 2, the exact range in which the kernel is positive semidefinite for arbitrary finite real charge sets, and optionally make tau layer-dependent to obtain multiscale interactions. This provides a principled alternative to unconstrained learned distance biases and can be used either as an attention-logit bias or as a…

Service-Cost-Independent Admission

Use the paper's independence condition as a design principle: prevent the gate's type-dependent admission behavior from being strongly correlated with downstream service cost. In an MoE or dynamic inference system, this discourages the gate from rejecting cheap requests and then preferentially admitting expensive requests when the queue happens to be shorter.

Conserved Poisson Feature Noise

Replace iid dropout or iid activation noise on spatial tokens with fluctuations generated by a conserved diffusing density. Each token receives a positive mass variable whose total mass is preserved, while Poissonian stochastic flux produces correlated perturbations that explore coherent local patterns rather than independently corrupting every feature. The density is autonomous and detached from autograd, so the regularizer adds little computational overhead.

Fast-Class MoE Router

Replace a flat stochastic MoE router by a two-level continuous-time routing model: experts within a group communicate rapidly, while transitions between groups occur slowly. Use the effective class-level stationary distribution as a soft load-balancing prior, reducing routing oscillation while preserving expert specialization.

Futile-Cycle Dissipation Monitor

Use the paper's multicycle result to distinguish useful parameter motion from internally circulating optimizer activity. Add an auxiliary two-cycle diagnostic to an optimizer or recurrent training loop: one cycle represents net loss-improving motion, while another represents momentum or noise circulation that can remain active even when the net parameter update is nearly zero. Penalize or throttle this hidden circulation to prevent apparent convergence from masking high update variance and…

Tangent Brownian symmetry breaking

Replace ordinary isotropic residual noise in a normalized continuous-depth block with projected Brownian forcing on the unit sphere. Apply a shared random symmetric quadratic drift to all tokens, plus a small token-specific tangent perturbation; the shared term preserves structured antipodal dynamics while the independent term removes persistent symmetry and cluster degeneracy. This is intended as a controlled stochastic regularizer, not merely additive Gaussian noise.

Spin-Wave Nonlinearity Damping

Use the paper's exponential dressing of an activity coupling as an adaptive gate on a neural network's nonlinear residual branch. The branch is strongly suppressed when the local activation fluctuation variance is high, producing an automatically linearized and more stable update, while low-variance representations preserve the learned nonlinear interaction.

Log-Correlated Extreme-Value Logit Regularizer

Calibrate the maximum attention logit in each head against the log-correlated extreme-value law instead of applying fixed clipping or a fixed max-norm penalty. Penalize only maxima that exceed the predicted log N minus three-quarter log log N baseline by an unusually large order-one fluctuation, allowing ordinary sharp attention while suppressing rare pathological spikes.

Rough Multiplicative Random Features

Replace explicitly stored independent random positional features with deterministic multiplicative phase features generated from a small table of random phases indexed by primes. Restrict positions to integers whose prime factors exceed a slowly growing threshold, because the paper's central-limit result says periodic weighted sums over these rough integers recover Gaussian behavior despite strong multiplicative dependence.
