Wittrick–Williams Mode Enumerator

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.

Rankine–Hugoniot Front Tokens

Augment a 1D neural operator or transformer with explicit tokens for detected discontinuities. Advance each front analytically using the local Rankine–Hugoniot speed and train the network only to reconstruct smooth regions and the residual caused by source terms and grid resolution.

Nullspace-coordinate constrained operator blocks

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.

Fractional Memory State-Space Layer

Replace a standard recurrent state update or finite-order SSM filter with a causal relative-history operator using a weakly singular kernel k(s)=s^{p-1}m(s), where 0<p<1. The resulting layer retains information over a power-law range of timescales and introduces tunable frequency-dependent phase and attenuation, while remaining implementable through a small bank of exponentially decaying states.

Orbit-Consistent Equivariant Distillation

Constrain a student policy to transform its action in the same way that the input state is transformed, while constraining its value estimate to remain unchanged. During distillation, augment every teacher-student pair with several symmetry-transformed copies and penalize disagreement after transforming the student action back to the original frame.

Hypoelliptic transport-diffusion layer

Replace an isotropic local mixing layer with a kinetic layer that smooths features in x and transports them in y along the characteristic direction x. The layer should be useful for phase-space data, learned simulators, and world models in which positions or transported quantities evolve through coupled drift and diffusion rather than independent Euclidean motion.

Bounded Telegraph Exploration for Optimizers

Add a bounded colored exploration force to an optimizer by filtering a sum of independent two-state telegraph signals through a stable linear relaxation equation. Unlike Gaussian momentum noise, the perturbation has a strict amplitude bound and a tunable finite correlation time, reducing rare destructive parameter excursions while retaining structured exploration.

Mean-Square Proximal Relaxation Optimizer

Partition neural-network parameters into blocks and update each block using a stochastic proximal best response, followed by Krasnoselskii relaxation. The relaxation factor and minibatch size become explicit stability knobs: aggressive stochastic updates are damped, while larger batches are used when the estimated update variance approaches the mean-square stability boundary.

Tikhonov-Minimum-Norm Hypergradients

Replace the usual inverse-Hessian implicit hypergradient with the derivative of the minimum-norm inner solution. Compute it as the limit of derivatives of a uniquely solvable Tikhonov-regularized problem, using a decreasing damping parameter and conjugate-gradient solves. This should make bilevel training usable when the inner model is overparameterized or has flat directions.

Wasserstein Speed-Limit Controller

Wrap stochastic optimization or iterative neural inference in a controller that measures how far the state distribution moves during each interval and compares this motion with the available noise-dependent entropy-production budget. The controller increases the learning rate or reduces inference steps only while the trajectory remains inside the predicted speed-limit region, preventing fast jumps that cause accuracy collapse.

Adaptive Zonotope Safety Shield

Wrap a neural policy with an online disturbance estimator and a zonotopic reachability shield. Instead of rejecting actions using a permanently worst-case disturbance set, update the disturbance zonotope from observed transition residuals and accept an action only when the resulting reachable set remains inside the safe region.

Fisher-Geodesic Finite-Step Annealing

Replace uniformly spaced diffusion or energy annealing schedules by a finite sequence of quench-relax stages whose intermediary distributions are approximately equally spaced in Fisher-Rao distance. Each stage abruptly changes the model energy or noise level and then runs a short relaxation phase; the schedule concentrates stages where the distribution changes most sharply. This should reduce nonequilibrium mismatch at a fixed number of sampler evaluations and avoid large distributional jumps…

Fractional-memory recurrent state

Construct an efficient recurrent or state-space layer whose impulse response follows Mittag-Leffler relaxation instead of a single exponential. A bank of stable diagonal state channels approximates the long power-law tail, allowing the layer to retain information over widely separated timescales with only \(K\) states per feature.

Mittag-Leffler second-moment optimizer

The resulting preconditioner remembers rare or old gradient directions with a power-law rather than geometric decay, which may improve optimization on nonstationary, sparse-gradient, or long-horizon problems.

Cohomological Quotient RNN

Build a recurrent or state-space model with a base state carrying task-relevant dynamics and an explicitly contracting auxiliary state. If the training loss or energy depends on the auxiliary state, replace it by a quotient loss plus an analytically known telescoping correction; long-run optimization and invariant averages are then unchanged, while transient fiber effects decay geometrically.

Fixed-Penalty Linearized Augmented-Lagrangian Training

Replace a neural-network penalty loss for differentiable equality constraints with a primal-dual update that solves one positive-definite linear system per step and then updates multipliers using the actual nonlinear constraint residual. Keep the penalty coefficient fixed instead of increasing it during training, reducing the usual penalty-conditioning tradeoff while directly controlling constraint violation.

Use this field inside kick-drift-kick proposals and apply an exact Metropolis correction, allowing the proposal field to be measurable and nonconservative rather than an exact neural-energy gradient. The experiment should test whether acceptance rates and posterior samples remain stable as the rough-energy resolution increases.

Persistent Hamiltonian categorical sampler

Replace independent categorical proposals or reversible Metropolis updates for discrete latent variables with a lifted sampler carrying persistent continuous edge momenta. Neighbor transitions are biased by the momentum and use a symmetric energy factor, so momentum reversal gives the required balance relation for the target Gibbs distribution while ordinary dynamics remain non-reversible. This should reduce random-walk behavior when sampling multimodal categorical latents or token sequences.

Dynamic-programming Doob sampler for exact rare-event conditioning

The module computes a backward feasibility message and reweights each neural transition toward states that can still satisfy the constraint, producing a conditioned process equivalent to a Doob transform.

For a stochastic dynamical model, the residual is computed using the infinitesimal generator, while terminal, safe, and failure boundary conditions are imposed through separate penalties.
