What the math gives to ML
The paper constructs H-distributions that record localized correlations between weakly convergent Lp sequences and their conjugate-dual sequences, resolved by Fourier direction. The transferable asset is a non-Hilbert-space directional multiplier pairing that detects persistent anisotropic oscillatory structure. A practical neural-network adaptation is a regularizer on activation and residual tensors that penalizes excessive concentration of this cross-spectrum in particular directions.

Estimate localized directional Fourier correlations between intermediate activations and their loss residuals, then penalize anisotropic concentration. The method can discourage unstable feature directions and improve robustness without requiring a full microlocal distribution reconstruction.
