What the math gives to ML

The paper gives a tunable hierarchy of temporal moment constraints: a dynamical system can reproduce Haar statistics through order k while retaining state dependence in higher-order moments. The transferable asset is the explicit separation between low-order distributional invariance and higher-order memory, rather than the specific quantum drive construction. This suggests a regularizer for recurrent, state-space, or diffusion trajectories that matches hidden-state moments up to a chosen order k, using k as a knob between strong mixing and preservation of dynamical information. The first test should determine whether low-order moment matching stabilizes hidden dynamics without erasing task-relevant temporal structure.

Tunable Haar-Moment Mixing Regularizer

Regularize hidden-state trajectories so that their temporal statistics match the moments of an isotropic Haar-distributed state up to order k, while deliberately leaving moments above k unconstrained. Use k as a controllable mixing knob: k=1 or 2 suppresses drift and anisotropic variance, whereas larger k imposes stronger distributional invariance and may remove useful temporal information.
