Parameterize a generative or density-evolving model as a composition of diffeomorphic optimal-mass-transport maps rather than unconstrained residual layers. Each layer transports one smooth positive density to another through a learned squared-distance OT map, while compositions provide a principled universal family for transformations connected to the identity.

Replace a conventional whitening transform with a constrained whitening layer that minimizes cross-channel covariance while requiring every output channel to remain correlated with its designated input channel by at least a threshold \(\rho_{\min}\). The layer exploits the orthogonal freedom in whitening to find a rotation that preserves channel identity instead of arbitrarily mixing features. It can be inserted before an MLP, convolution, or attention projection and compared directly against…

Augment each recurrent or state-space hidden channel with a two-dimensional oscillatory state and periodically compute a pseudo-phase from its Cartesian coordinates. Use sparse event-triggered feedback to reduce the squared phase order parameter, preventing hidden channels from synchronising while avoiding the computation and communication cost of continuously recomputing the control signal. The controller acts as a tangent rotation of each two-dimensional hidden state, changing phase diversity…

Prune redundant attention heads using separate similarity scores for sink behavior and content routing. Two heads are considered safely redundant only when their normalized content compositions are close in Aitchison distance and their sink-mass trajectories are also close, avoiding pruning decisions dominated by a shared sink token.

Distill a teacher's attention into a student by matching sink mass and the normalized content distribution as separate targets rather than applying one KL divergence to the entire attention row. Use the Aitchison distance on the content composition, which compares relative token allocation and prevents a large common sink probability from overwhelming differences between content tokens.

Replace pointwise hidden-state distance penalties with a trajectory metric that measures the largest discrepancy over a short rollout. This directly controls transient amplification: two nearly identical states are considered unstable if their predicted trajectories separate at any intermediate time, even when they happen to reconverge at the final step.

Replace an unconstrained recurrent or neural-ODE hidden state with a positive state driven by reaction-like polynomial flows whose rate vector is modulated by inputs or context. Train the module together with an ISS penalty so bounded gate perturbations produce a bounded hidden-state deviation, preventing long-horizon amplification while retaining nonlinear computation.

Represent local feature channels as a smooth directional signal and aggregate them with a partition-of-unity family of learnable spherical atoms instead of hard angular bins. Use the atom Gram matrix to whiten the descriptor and add a projected-energy loss, so the network is rewarded for retaining information in the directional subspace rather than merely producing large correlated channel responses.

Replace hand-tuned exponentially separated coefficients for multiple neural objectives with weights obtained from a local KKT certificate. For L1 hinge penalties, solve a small linear program that maximizes the smallest tier weight while enforcing approximate stationarity of the weighted objective at the current priority solution. This should preserve high-priority behavior more reliably than fixed loss weights while avoiding unnecessarily large coefficients.

Add a topology-aware loss to a segmentation or implicit-shape network by computing radial extended persistence on the predicted boundary rather than on the full predicted mask. Match signed persistence intervals of the prediction to those of the target, penalizing missing, extra, or incorrectly ordered radial components and holes. This should provide a compact shape prior that is sensitive to anatomy-specific radial organization while avoiding volumetric homology computation.

For systems with a repeating orbit, train a periodic neural dynamical model together with a return map whose transverse deviations contract after each period.

Attach an evidential cost head to a neural graph model, representing each edge cost by a weighted set of interval boxes, and compress this representation before the downstream shortest-path or routing solver. Instead of minimizing Jaccard or Jousselme distance between the original and compressed mass functions, choose merges that minimize the induced cost error on the currently selected route, while enforcing a conservative monotonicity condition so that the resulting path regret is bounded.

Use the reachable-safe-set viewpoint to make training data generation adaptive: maintain an approximation of the states reached by the current neural policy, identify boundary regions with weak barrier margin, and sample there until the set is sufficiently covered.

Add a dedicated near-zero-loss Langevin phase after ordinary training, with inverse temperature increased while the optimizer remains stochastic.

Use dissipative dynamics directly on the SU(d) manifold instead of unconstrained Euclidean recurrent updates. A Riemannian gradient or damped Landau-Lifshitz-Gilbert-like flow preserves the unitary constraint and supplies an explicit Lyapunov certificate: the associative-memory energy should decrease monotonically until the state reaches a recalled attractor.
