Replace a single local message-passing or convolution operator by a spectrally controlled mixture of fractional and ordinary diffusion. The exponent σ is learned or scheduled, while a crossover gate forces the model to change parameterization near the renormalization-group threshold σ*=2, allowing long-range propagation when useful without retaining an unnecessarily nonlocal operator at short scales.

Replace a purely diagonal or block-diagonal optimizer preconditioner with a truncated Woodbury correction selected in interaction coordinates. Per-example gradient combinations are ranked by their response through the base inverse preconditioner, so the retained directions are those most affected by curvature after normalization rather than merely those with the largest raw gradient norm.

Replace a dense neural interaction graph by a dynamically activated graph whose edge $(u,v)$ is retained only when its effective coupling exceeds the local spacing of response modes. The network remains sparse below the connectivity transition but becomes globally communicating once a giant component forms, providing a controllable alternative to arbitrary magnitude pruning.

Add a distributed spectral positional encoding to a graph neural network, graph transformer, sparse-attention model, or MoE router by computing the dominant eigenvector of the current weighted adjacency matrix with a few warm-started power iterations. Unlike a Fiedler-vector feature, this encoding uses only local neighbor aggregation, is naturally nonnegative for nonnegative adjacency weights, and can be updated incrementally when the graph or edge weights change.

Use the OT spectral bound as a conditioning signal for optimizing parameters of a neural cost or inverse-OT objective. Adapt the parameter step size and add a covariance floor whenever the estimated Jacobian lower bound collapses, preventing optimization from entering regions where Sinkhorn outputs become insensitive to the learned cost.

Replace a dense translation-invariant interaction matrix with a positive-definite Toeplitz kernel K_n(e^f) whose log-spectrum is parameterized by a small number of Fourier coefficients with 1/|k| decay. Use the paper's explicit quadratic term as a spectral-volume budget, allowing long-range structure while discouraging uncontrolled determinant growth and ill-conditioning. Subtracting this term from a log-determinant regularizer leaves a residual intended to capture higher-order deviations from…

Search sparse reservoir wiring in graph space rather than repeatedly testing every candidate with its full nonlinear dynamics.

Replace ordinary absolute positional embeddings with coordinates on a learned flat torus and use dual-lattice Fourier characters as positional features. Control the covariance of the coordinate fundamental domain so that the paper's inequality guarantees a lower bound on the smallest nonzero positional frequency, preventing the learned periodic coordinate system from developing arbitrarily weak or nearly constant modes.

Constrain a recurrent or state-space transition matrix so that its eigenvalues avoid a configurable annulus around the unit circle.

Replace fixed graph message weights with a source-node activity gate that amplifies or suppresses every outgoing message from that node. Use the linearized epidemic growth condition to calibrate the residual propagation strength so that the dominant graph mode is near, but below, an explicitly chosen stability threshold rather than being determined accidentally by the graph spectrum.

Insert a proximal layer after a graph, mesh, or spherical convolution that groups all coordinates belonging to the same Laplacian eigenspace and applies one shared shrinkage gate to the whole group. Unlike coefficientwise spectral pruning, the result is unchanged if the eigenvectors inside a repeated eigenspace are rotated, preventing arbitrary basis-dependent feature selection.

Replace unconstrained attention score vectors by normalized SU(2) coherent-state responses of a positive operator on an (N+1)-dimensional spin space. Each query produces a smooth bounded response over a fixed spherical grid, while values are aggregated normally. The coherent-state kernel imposes geometric structure and exposes a controllable concentration parameter N.

Use the conditioning of a learned symmetry-commutant manifold as a training-time detector for frozen or weakly reachable hidden-state regions. When replica observables become nearly linearly dependent, the commutant Gram matrix becomes ill-conditioned; reduce injected noise and learning rate there, or perturb only directions with measurable response. The mechanism predicts a transition in relaxation curves at a conditioning threshold rather than relying only on validation loss.

Replace an unconstrained recurrent transition with a second-order resonant state whose restoring matrix is full-rank but whose damping is low-rank.

Augment a sequence network with a learned staggered matrix-product-operator symmetry and penalize its commutator with the network map.

The model should preserve generalized symmetry sectors and exhibit lower commutator error on…
