Conservative amortized collision layer

Add a learned stochastic pair-interaction layer to a particle graph neural network, with a conditional normalizing flow generating the post-interaction relative state. Parameterize the update in center-of-mass and invariant relative coordinates so every sampled interaction preserves pair momentum and kinetic energy exactly. The flow learns the transition law directly from observed scattering or trajectory data, replacing repeated numerical collision solves or unconstrained message-passing…

Polynomial Jacobian Non-Collapse

Add a two-output anti-collapse regularizer based on the determinant of the Jacobian Gram matrix, together with a penalty against proportional highest-degree coefficient tensors. The paper's inequality predicts that preserving coefficient non-proportionality prevents the output distribution from concentrating on thin curves or tiny regions, potentially improving coverage of a two-dimensional latent or generative output.

Distribution-Preserving Fragmentation Augmentation

Augment spatial training examples by replacing a compact active region with several separated components while preserving its exact value histogram, total active area, and amplitude. The augmentation probes the nonlinear interaction between diffusion-like receptive fields and threshold activations, which the paper shows can make fragmented and compact inputs evolve in opposite directions despite identical distributions.
