Bounded independence for the inverse star discrepancy

What the math gives to ML

The paper provides a constructive way to replace large collections of independent uniform samples by only k-wise independent points while retaining a Monte Carlo-scale star-discrepancy guarantee, with k growing only as O(d(1+log(1+N/d))). The transferable asset is not merely reduced randomness: the generated point set is globally space-filling for all axis-aligned boxes, which can reduce integration error for bounded-variation stochastic objectives. A practical neural-network use is to drive repeated augmentation, masking, or latent-variable evaluations with a deterministic finite-field polynomial sampler, then compare its training variance and convergence against iid sampling at equal sample count. The method should be applied first to uniform-parameter augmentation or quadrature-like objectives, where the Koksma–Hlawka guarantee is relevant, rather than assumed to improve arbitrary Gaussian noise injection.

Polynomial bounded-independence sampler for augmentation

Replace iid uniform augmentation draws or Monte Carlo quadrature points by a space-filling k-wise independent point set generated from random polynomials over a finite field. The construction uses far fewer random bits and can reduce integration error whenever the network loss as a function of augmentation parameters has moderate Hardy–Krause variation.
