Reference-Preserving Martingale Layer

Replace an unconstrained stochastic transition between categorical or discretized latent distributions by a transition matrix that preserves a prescribed reference distribution while mapping relative populations through a martingale. This prevents the layer from inventing arbitrarily sharp deviations from the reference and imposes a convex-order monotonicity condition on uncertainty across layers or diffusion time steps.

Pointwise complexity-gated inference

Use a local chaining complexity computed from an empirical input metric to predict stochastic output error for each individual input. Easy, locally concentrated inputs can use fewer dropout, ensemble, or diffusion samples, while high-complexity inputs receive additional computation; unlike a global confidence threshold, the allocation varies with the input.

Gaussian-mixture kinetic neural solver

Make a neural network predict a positive Gaussian-mixture representation of the distribution function rather than independent values on a momentum grid. Use the mixture parameters inside a differentiable Boltzmann collision operator, so training directly enforces the interaction mechanism and exposes the relaxation spectrum responsible for ballistic-to-hydrodynamic crossover.

Autocatalytic Hysteresis Memory Cell

Replace or augment a recurrent hidden coordinate with a nonnegative bistable autocatalytic state driven by an external control signal. The cell retains information through metastable low and high states, while a periodic or slowly varying control produces a controlled phase lag and hysteresis useful for temporal regime detection. Explicit noise can be injected to test whether it enhances switching near the predicted intermediate-frequency regime.

KS-Adaptive Graph Halting

Use the KS ratio to decide how many message-passing layers to execute per graph or per node, rather than selecting a fixed depth. In the subcritical regime, stop once the predicted remaining effect is below a tolerance; in the supercritical regime, continue until the observed logit change becomes small or a larger budget is reached.

Subcritical Ancestral Attention

Construct a sparse attention layer by sampling backward token histories as a continuous-time branching process rather than allowing every query to attend to every key. Each active ancestor either dies or branches into a bounded number of candidate ancestors, with branching probability controlled by a small parameter. The branch-out penalty predicts exponentially small probability of long, highly branching histories, providing a direct knob for receptive-field size and attention FLOPs.

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.
