Use a window of observed neural-network update trajectories to identify the set of local quadratic objectives and preconditioners that are consistent with the observed optimizer behavior. Rather than selecting one arbitrary curvature model, retain the nullspace of compatible parameters and use its dimension or smallest singular value as an identifiability and stability diagnostic.

Attach a finite mixture of zonotopes to each uncertain neural input or hidden state, and propagate every mixture component through affine layers and conservative nonlinear relaxations. When the number of components grows, merge components only with an enclosing zonotope and sum their probability masses, preserving a formal lower bound on the probability that the true activation lies in the represented set.

Replace independent top-k token selection by a quality-weighted determinantal subset objective based on the Hardy–Szegő kernel. Tokens with high learned quality are preferred, but geometrically redundant tokens have a small determinant contribution, encouraging diverse sets of routed experts, retrieved items, or attended context tokens.

Replace unconstrained latent or neural-ODE dynamics with a strict-feedback cascade whose virtual controls are generated recursively by nonadaptive backstepping. Add a fixed internal-model oscillator when the desired output contains known-frequency periodic components, so the network tracks persistent targets without learning an unstable long-memory representation. The controller is designed to tolerate bounded neural-model mismatch and disturbances through an input-to-state stability margin.

Construct a contractive multi-branch recurrent or generative network whose branches define an iterated-function system, and regularize it so that branch entropy is high relative to average contraction while compositions remain exponentially separated. The target is a measurable attractor-dimension law rather than only a benchmark improvement: the invariant measure dimension should approach min(d, H divided by chi), where d is state dimension.

Augment a neural-network update with an auxiliary, damped stochastic branch that acts like the paper's floating dissipative reservoir. A trainable mixing phase \(\phi\) combines the task-gradient branch and auxiliary branch; \(\phi\) is adapted to make the auxiliary response to a chosen control perturbation nearly zero while retaining a finite task-gradient response. The intended benefit is selective insensitivity to nuisance hyperparameters or perturbations, with a measurable response peak…

Replace an unconstrained multiplicative interaction between two nonnegative neural features by a lifted gate whose first and second moments satisfy the paper's semidefinite relaxation for the set F = {(x1,x2): x1,x2 >= 0, x1 x2 <= 1}. Insert the gate into an MLP, attention score, or MoE router to prevent explosive feature products while retaining a tractable convex feasible set.

Replace unconstrained or entropy-regularized MoE routing with a minimally disruptive update that preserves a lower bound on the log-determinant of the experts' weighted output span. The router still tracks the desired mixture, but a projection prevents the active experts from becoming linearly redundant or collapsing onto a low-rank subset.

Treat a selected neural submodule as an open dynamical system embedded in the rest of the network.

Replace a conventional covariance or density-matrix discrepancy with the geodesic quantum f-divergence between an example's predicted positive-definite matrix and its target matrix. Use t as a controllable interpolation between the standard Petz divergence at t=0 and the maximal divergence at t=1, with f(x)=x log x or another operator-convex power generator.

Replace a neural network head that predicts a covariance or other SPD matrix entrywise with regression in the matrix-log domain. The network predicts a symmetric matrix in unconstrained Euclidean coordinates, the matrix exponential guarantees an SPD output, and training can use intrinsic log-Euclidean or affine-invariant errors rather than Frobenius error on raw entries.

Replace fixed-path robustness testing with a coupled continuation procedure that increases an adverse perturbation while simultaneously optimizing a bounded corrective response, such as feature-gating, normalization, or a small adapter. Define the model's margin as the cumulative perturbation at which its equilibrium, prediction, or input-output Jacobian becomes singular or exceeds a prescribed gain threshold; train the corrective response to enlarge this margin subject to an explicit cost.

Augment a graph neural network with structural features computed from counts of small pattern homomorphisms whose pattern vertices are constrained to lie in selected vertex subsets. Unlike ordinary local aggregation, these features encode dense subgraph structure and can separate graphs or node sets that have identical low-order neighborhood statistics. Use a small learned bank of pattern graphs and sampled subset tuples so the method remains practical.

Regularize neural features indexed by a compact transformation group using the three conditions from the vector-valued Pego theorem: nearby group transformations should produce nearby features, high group-Fourier coefficients should have small energy, and feature energy should remain concentrated in a fixed low-dimensional value-space subspace.

Represent a collection of neural directions as generators of a zonotope and reward the volume spanned by their subsets. The objective favors complementary, non-collapsed vectors rather than merely pairwise-separated vectors, making it suitable for attention heads, MoE expert signatures, or embedding prototypes.

Replace an unconstrained q-way polynomial or tensorized feature layer with separate decomposable and primitive interaction channels. The decomposable channel models interactions explainable as products of lower physical-weight feature blocks, while the primitive channel captures residual factors that cannot be represented by those products. This should reduce redundant high-order parameters and provide a controllable inductive bias for compositional or disentangled representations.
