Replace raw molecular orientation vectors with local scalar features invariant under common three-dimensional rotations and the apolar transformation u_i -> -u_i. Feed these channels to a CNN autoencoder, VAE, or contrastive encoder so that configurations on the same physical symmetry orbit have identical inputs or latent codes. This should improve unsupervised phase discovery without supplying order-parameter labels.

Train a generator with a Coulomb discrepancy rather than, or in addition to, a local adversarial or reconstruction loss. The induced force attracts generated mass toward the target while repelling excess source mass, giving a geometry-aware anti-collapse regularizer.

Add a learnable cyclic-coordinate mechanism to latent dynamics so that selected latent coordinates do not enter the Hamiltonian and their conjugate momenta become conserved. This provides an explicit dimensionality-discovery and invariance bias, encouraging the model to represent nuisance or symmetry directions compactly instead of spending independent dynamics capacity on them.

Replace a conventional two-layer channel mixer in a reversible architecture with the tropicalization of two cluster mutations. For every pair of channels, the block applies sign-dependent integer shears and reflections, giving a cheap piecewise-linear transformation that is exactly invertible and requires no stored activations during backpropagation. Continuous trainable affine scale and mixing parameters can be placed around the fixed tropical core.

Use the differentiable covariance chart to construct a Fisher-information preconditioner for the edge and innovation parameters of a linear-Gaussian neural module. Instead of applying an isotropic Euclidean update, whiten parameter steps according to how strongly they change the predicted Gaussian distribution. This targets ill-conditioning caused by redundant paths, correlated latent nodes, and badly scaled innovation covariances.

Replace an unconstrained covariance or dependency module with a topologically ordered linear-Gaussian DAG whose edge transforms and innovation covariances are neural-network parameters. The layer computes a joint covariance by a differentiable triangular solve, allowing downstream losses to use uncertainty, conditional prediction, or dependency penalties while preserving positive semidefiniteness by construction. This is especially suitable for graph neural networks, structured VAEs, and…

Replace the usual gradient-descent or conjugate-gradient data-fidelity step in an unrolled reconstruction network with an exact Woodbury proximal layer for grouped multiplexed measurements. The layer can be inserted between learned denoising blocks and should provide stronger measurement consistency at a fixed number of unrolled stages, while avoiding inner iterative linear solves.

Train a conditional generator or set-valued predictor so that stochastic target refinements preserve the barycentric representation required by the source while allowing valid target-side diversity. The regularizer discourages collapse of multiple legitimate outcomes to one point without treating mean-preserving spread as semantic misalignment.

Replace an unconstrained latent-to-data map in a small generative model with a learned Brenier map T equal to the gradient of a convex potential, transporting a Gaussian latent distribution toward a density proportional to exp(-B) times the Gaussian density. Constrain B to be globally L-Lipschitz and use the resulting dimension-free Jacobian ceiling as an adaptive stability target. This should reduce pathological local expansion without requiring B itself to be convex or its Hessian to be…

Add a post-processing or differentiable output layer that first matches each predicted marginal distribution to the data marginal and then corrects the remaining joint dependence by transporting the predicted copula to the observed copula. This directly targets the discrepancy that sequential marginal or quantity-of-interest constraints cannot remove.

When a neural model defines a product distribution over coordinates, compute the discrepancy to a target product distribution from per-coordinate divergences using the exact tensorization rule instead of sampling full vectors and estimating a joint divergence. Implement KL, chi-squared, and squared-Hellinger variants as drop-in losses, with an optional learned choice among these mathematically tensorizable families.

Use coordinate hit-and-run rather than isotropic Gaussian random walks to generate latent negatives or augmentation trajectories inside a convex latent domain K. At each step, select one coordinate and resample the entire feasible chord along that coordinate; the paper's l0-isoperimetric theorem predicts that sets of non-negligible mass cannot be separated by severe coordinate-only bottlenecks when K is well-conditioned relative to an unconditional body Q.

Construct a recurrent or generative network from finitely many contractive branches whose hidden-state attractor has a prescribed similarity dimension.

Add a theorem-guided regularizer to neural optimal-transport potentials that limits curvature separately in each direction according to the target support width. Unlike an isotropic Hessian penalty, it permits larger curvature along directions where the target is wide and enforces stronger smoothing along narrow directions, preserving anisotropic structure while controlling the transport map's Lipschitz constant.

Replace raw squared penalties on generated feature means with the paper's nested information-projection statistic. A model output distribution is projected once onto structural constraints and once onto structural-plus-test constraints; their KL divergence produces a sample-size-scaled loss and an approximate chi-square p-value. This should help when constraints have different variances or are strongly correlated, because the KL geometry automatically adapts to their covariance instead of…

Place doubly stochastic stream mixing immediately before a quantizer, activation compressor, or latent bottleneck and jointly optimize task loss with estimated code length. The paper's entropy argument says that this linear mixing cannot increase differential entropy, so it can provide cross-stream representation capacity without an ideal entropy-rate penalty; the entropy bottleneck then learns which feature values deserve bits.

For models that predict probability distributions, replace the usual Wasserstein-2 loss or a Huber penalty on the final Wasserstein distance with a Huber penalty on quantile-by-quantile prediction errors. This suppresses gradients from localized outliers while retaining quadratic gradients on the majority of the distribution, which is useful for uncertainty prediction, histogram prediction, and distributional distillation.

This should reduce redundant high-order parameters and provide a controllable inductive bias for compositional or disentangled representations.
