What the math gives to ML

The paper's transferable asset is a structure-preserving low-rank evolution: compression is not allowed to discard directions representing conserved moments, and stochastic integration is chosen to respect the geometry of the original transport equation. This suggests a constrained latent-state compressor for neural operators, world models, or SSMs in which the low-rank basis is augmented with known invariant vectors before truncation. The most direct implementation is to combine augmented low-rank projection with an exact affine correction that preserves selected linear statistics after every learned or stochastic transition.

Invariant-Preserving Latent Compression

Replace unconstrained low-rank compression of a neural state with an augmented basis that always contains vectors representing known conserved quantities or diagnostically important linear statistics. After each learned transition, project the state back onto the affine constraint set with an exact minimum-norm correction, preventing rank truncation and model error from accumulating in those statistics.
