Add a bounded routing state to an RNN, state-space model, or mixture-of-experts layer, with several neutral fixed points representing persistent modes. The state moves between modes when far from a fixed point but escapes each mode only polynomially when close to it, creating controllable long memory without setting a linear eigenvalue arbitrarily close to one. A temperature parameter selects between an entropy-rich phase using many modes and a low-entropy phase concentrated near one preferred…

Replace random or k-means initialization of a k-expert router with a moment-based range finder on a calibration batch of hidden states. Estimate a low-dimensional second-moment subspace, enlarge it using one-free-index third-Hermite contractions, and fit the router's expert centroids and weights only in this resulting subspace. The router can then operate on projected hidden states while retaining an optional small residual adapter.

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.

Use the paper's explicit pixel-spacing error bound to make radial topological features and losses resolution-aware. Treat intervals whose endpoint changes are below the discretization tolerance as unreliable, and use the bound to select contour resolution or a persistence threshold instead of tuning these quantities arbitrarily. This can improve robustness to rasterization, small contour perturbations, and multi-resolution training.

Make Laplacian latency attention hardware-friendly by quantizing the exponential decay and row normalization to powers of two. Exponentials and divisions can then be implemented with lookup tables and integer shifts, enabling a low-bit attention kernel for neuromorphic and edge accelerators.

Approximate a long hidden-state or key/value trajectory by a small sum of exponential modes, storing only the mode nodes and vector weights instead of every timestep. Recover the modes from a Hankel matrix through an annihilating polynomial, then reconstruct the trajectory or a compact recurrent state during inference.

Give a token, patch, retrieval-item, or expert-selection module a learned utility f_theta(S) over subsets S, and penalize violations of the paper's submodularity and strong-submodularity inequalities. The resulting selector should prefer complementary elements: the marginal value of adding an item decreases when the current selected set is already rich in similar information. At inference, use greedy marginal-gain selection rather than independently thresholding token scores.

Add a neural feature, adapter, or expert block only through the component of its outputs that is orthogonal to the span of all previously installed blocks. Quotient coefficient directions that produce nearly identical outputs with an SVD or pseudoinverse, so the new block contributes intrinsic representational dimensions instead of duplicating old features. The expected benefit is a smaller effective architecture and better-conditioned block expansion.

Replace an unconstrained recurrent transition with a second-order resonant state whose restoring matrix is full-rank but whose damping is low-rank. The low-rank damping creates a small set of rapidly controlled bright modes and a large dark subspace with long memory, while a small optional damping term prevents numerical drift in completely dark modes.

Construct a sparse recurrent network with positive edge weights and Leaky-ReLU updates so that one selected hidden node, observed over a finite time window, contains enough information to reconstruct the full hidden state. Add an auxiliary decoder from the observed trajectory to the initial state or current state, and use graph rewiring or edge-growth until every hidden node has a directed path to the sensor within the observation horizon.

Replace isotropic variance control in a bottleneck or router with a spectral polarization penalty that drives each latent direction toward either variance 0 or variance 1. The intended result is an automatically selected active subspace: inactive coordinates can be pruned or quantized aggressively, while active coordinates retain information instead of being uniformly attenuated.

Replace a learned dense bilinear map with a structured family of signed orthogonal matrices. Given feature vectors y,z in R^n, produce r interaction features h_a = y^T H_a z / sqrt(n), where the H_a form a Hadamard/Clifford-like family; the resulting bilinear map has operator norm at most one when r is within the Hurwitz–Radon limit. Learn only channel projections and optional scalar gates around this fixed mixer.

Replace a uniformly sampled trajectory sequence by a binary temporal partition whose intervals are split only when the observed trajectory makes an excursion larger than a threshold. Encode one summary token per retained leaf, optionally including duration and endpoint displacement, so smooth trajectory regions receive fewer tokens while rapidly changing regions retain resolution.

Use a low-rank controller that observes and actuates only the graph's harmonic coordinates rather than all edge features. For a graph with first Betti number beta_1 = dim ker(B), a beta_1-dimensional cycle basis is sufficient to represent the entire harmonic sector, yielding a compact recurrent memory or adapter for circulation-dependent graph dynamics.

Replace top-k token pruning by greedy maximization of a diversity-aware monotone submodular utility under a spacing or coverage constraint. The selector repeatedly chooses the feasible token with the largest marginal utility, avoiding the redundant-token failure mode of independent score ranking while inheriting a constant-factor approximation guarantee under the stated 2-system abstraction.

Implement f(A)b inside a neural network with a short Lanczos recurrence instead of an eigendecomposition or dense matrix-function operation. Use an SPD operator A such as a regularized graph Laplacian or feature covariance matrix, and choose the number of iterations by monitoring successive approximations. For Stieltjes functions, Lanczos is guaranteed to be close to the best vector in the same Krylov subspace.

Replace an unconstrained spatial gate or interpolation kernel by a compactly supported function whose translates under a lattice exactly sum to one. Impose zero products between translates under a second lattice, so active gates do not collide; thresholding a positive superlevel set then provides a nonzero separation margin and predictable sparse computation.
