Replace independent per-sensor temporal encoders with a shared two-dimensional transform whose temporal and spatial phase channels remain algebraically distinguishable. Train a neural residual detector and localization head on the transformed coefficients, forcing perturbations with the same temporal signature but different positions to differ primarily in their spatial phase.

Augment an RNN or state-space model with a finite-state binary-context module whose transitions are those of a de Bruijn graph, while a signed transition channel records a quadratic parity function of the recent context. The exact finite-memory branch preserves cancellation-sensitive parity features that a continuous hidden state may forget, and a learned readout can combine it with the ordinary neural state.

Replace a local smoothness penalty or local state transition along a sequence or depth coordinate by a marginal fractional quadratic energy with Fourier multiplier |k|. The sigma=1 kernel is nonlocal and scale-free, so it can preserve long-range correlations while suppressing high-frequency instability more selectively than an ordinary Laplacian penalty.

Insert a sparse heavy-tailed nonlocal mixing operator into a residual sequence, graph, or spatial network so that information can traverse distant positions without stacking many local layers. Use the critical tail exponent s = 1/2, whose truncated first moment grows logarithmically and predicts an effective propagation distance proportional to depth times log depth rather than merely depth.

Add a fixed, spatially correlated perturbation field to every layer of a CNN or 2D state-space model, with the perturbation decomposed into transverse and longitudinal Fourier components. Unlike ordinary injected noise, the same field is reused for all training examples and all forward passes, allowing it to act as a structured architectural flow that can promote global feature alignment. Sweep the transverse fraction at fixed total perturbation variance and test for the predicted ordering…

Replace the dense output of selected linear projections with a two-sided magnitude threshold that emits zero for small values but preserves signed large values. Learn one positive threshold per projection, or optionally one threshold per output channel, so the network discovers where sparse events can be removed while retaining outlier information.

Replace an explicit recurrent transition with a learned descriptor relation in latent space, allowing some latent coordinates to satisfy algebraic constraints rather than being numerically integrated. Fit the relation using total-least-squares or iterative PCA on the jointly observed trajectory, so noise in every channel is treated symmetrically and the model can discover whether the latent system is index-0 or index-1.

Use exhaustive finite-state analysis as an architecture-search objective for coupled recurrent motifs. Instead of independently tuning a normalization gate and a WTA gate, enumerate their possible interfaces and select couplings that create group action only on a small joint image set, yielding controlled reversible subdynamics embedded in an otherwise dissipative system.

Construct a neural state-space model with an explicit first-order input-to-output path instead of forcing every output to depend only on deeply propagated hidden states. Penalize or reject learned linearizations whose transfer matrix has relative degree greater than one, then train a storage-function certificate for the remaining passive dynamics. This preserves the paper's relative-degree compatibility condition while allowing high-order internal memory.

Replace an Erlang delay or exponential smoothing cascade in a recurrent or state-space layer by a positive rational kernel of the form \(\kappa(u)=C e^{-a u}p(u)^2\). Choose the degree-\(m\) polynomial by deleting the adjacent pair of Laguerre zeros with smallest relative gap from \(L_{m+2}\), then rescale the resulting density to unit mean. This preserves a nonnegative impulse response while reducing temporal jitter relative to Erlang filters.

Construct a residual neural network or graph message-passing layer whose skip edges are sampled with probability proportional to their distance as $|i-j|^{-(1+\sigma)}$, while retaining a small local backbone.

Replace an unconstrained Fourier-domain linear mixer with a bank of positive spectral kernels and a max-times erosion aggregator. For a nonnegative Fourier magnitude f, each kernel produces a quotient response f/psi_k and the layer takes the pointwise supremum over kernels, giving exact positive homogeneity and monotonicity. This is most suitable as a drop-in spectral mixing block in a CNN, vision transformer, or state-space model.

Replace an unconstrained multiscale residual block by the sum of a fractional diffusion branch and a drift or transport branch whose strength follows the PDE scaling law. At finer spatial scales, the drift coefficient is multiplied by R^{2s-1}; this suppresses unstable transport when s>1/2 while preserving equal-strength diffusion and drift at the critical value s=1/2.
