Use the paper's families of local graph embeddings to identify repeated occurrences of the same causal substructure across time steps, environments, or entities. Feed every aligned occurrence through one shared transition mechanism and impose an explicit equivariance penalty under the symmetry group acting on occurrence indices, rather than learning an independent predictor for every context.

Construct a graph and its spectral positional features using affinities between inputs after optimally aligning one input over the known symmetry group. Feed these quotient-space eigenvectors to a transformer or graph neural network, so symmetry-equivalent examples receive the same structural coordinates without storing augmented copies.

Replace uniform minibatch sampling by a fixed-size determinantal point process whose similarity matrix is a diffusion kernel on the training-data k-NN graph. The sampler repels nearby or redundant examples while preserving multiple diffusion modes, so a small batch should cover intrinsic data geometry and provide lower-variance estimates of losses and gradients.

Replace the arbitrary labelled target graph in each flow-matching pair by the node permutation that minimizes its Euclidean distance to the source graph. Construct the conditional interpolation and velocity target using this aligned representative, so the model learns transport in graph quotient space rather than wasting capacity on node-order mismatches.

Replace pointwise cross-modal or prototype-to-instance matching with a loss that compares source pairwise inner products to inner products between target conditional means. A source prototype can align to a cloud of target instances while preserving its semantic barycenter, instead of being forced to match every target instance individually.

Replace a fragile learned similarity score for continuous object coordinates with a projection residual against a learned signal subspace. Candidate coordinates are represented by normalized Fourier or positional feature vectors, and the score is the fraction of feature energy outside the estimated subspace. The score remains useful even when the estimated subspace is adversarially rotated, because the perturbation is controlled directly by a sine-theta distance rather than by assumptions about…

Add a bounded probing perturbation to the inputs or intermediate outputs of a neural sensor-fusion model, and choose the perturbation by maximizing separation between the predicted trusted-output set and output sets induced by candidate sensor attacks. Bounded feature and measurement uncertainty are propagated through local neural Jacobians as zonotopes, giving a conservative, geometry-based exposure objective rather than relying on random noise. Training can use the resulting margin as a…

Use farthest-triplet entropy as a low-bandwidth observable of whether a hyperbolic embedding is angular- or radial-dominated, then adapt the hyperbolic curvature rather than fixing it arbitrarily. In the isotropic shell regime, invert the entropy-to-signal curve to estimate the effective radial/angular parameter and select curvature that reaches a chosen geometric operating point.

Build a neural operator from frozen ambient mechanism blocks and a geometry-specific algebraic constraint adapter. The adapter parameterizes all outputs in the affine set satisfying sampled linear constraints exactly, so the network never produces boundary-violating states and does not require a penalty coefficient or post-step projection.

Use a learned scalar ordering function to turn a symmetric local Gaussian graph kernel into a directed, row-stochastic message-passing operator. The asymmetric tilt lets neighboring nodes communicate preferentially along an inferred dynamical direction, while the Gaussian factor retains locality and diffusion-like smoothing.

Parameterize an entropic OT cost only in directions that can change the transport plan, removing row-plus-column potential directions that are invisible because of OT gauge invariance. Whiten the remaining feature coordinates using their empirical covariance, producing an OT layer whose identifiable parameters have substantially more uniform sensitivity.

Convert each persistence diagram produced from an input, intermediate feature map, or graph filtration into a discretized persistence landscape and feed it to an MLP or concatenate it with ordinary neural features. Unlike a variable-size list of birth-death pairs, the landscape has a fixed tensor shape and is provably nonexpansive with respect to the diagram Wasserstein distance.

Replace an unconstrained edge-feature residual update in a graph neural network with separate cut-space and harmonic-space updates. The cut branch carries transfer information visible at nodes, while the harmonic branch models cycle circulation and can be given an independently chosen contraction rate, preventing persistent or unstable circulation features from contaminating node predictions.

Replace ordinary sum or mean pooling in a permutation-invariant set network by the complete family of basic tropical multisymmetric values. For an input set of n points in R^r, each feature computes the maximum total coordinate score obtainable by assigning disjoint rows to prescribed coordinate channels. The resulting representation is invariant to row permutations, separates all multisets, and inherits a bi-Lipschitz relation to optimal row matching, so nearby sets cannot be arbitrarily…

Train one functional flow-matching network against conditional velocity targets formed from randomly varying finite-rank reconstructions, including sensor sets that are not nested across training examples. Decode predictions from two sensor layouts into a common function representation and add a cross-layout consistency penalty.

Replace uniform node minibatches in a GNN with a coreset selected from a small random candidate set using local Laplacian-column coherence. Select nodes whose connectivity signatures are least redundant with already selected nodes, while retaining inverse-probability weights for unbiased loss estimates.

For an input with exactly $\alpha_a$ occurrences of each state $a\in\{0,\ldots,n-1\}$, corrupt it by repeatedly swapping two positions with different states instead of independently resampling tokens. This defines a Markov process on the connected fixed-profile multislice, preserving global composition exactly and avoiding the distribution shift caused by ordinary categorical masking.
