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.

Directional H-distribution regularizer

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.
