Attach a dynamic space-time barrier filter to a neural policy instead of directly imposing a noisy, memoryless CBF constraint on its action. The filter state integrates recent barrier residuals with a proper low-pass kernel, while the online safety QP continues to depend affinely on the policy correction, so high-frequency observation noise is attenuated without removing control authority.
For z neural branches that share a target, state, or routing observation, add a penalty on fluctuations in the branch direction visible to that shared signal. This implements the paper's centered-square conditioning mechanism: branches remain locally independent in hidden directions, while collective deviations that would produce inconsistent shared outputs are suppressed.
Make a neural network predict a positive Gaussian-mixture representation of the distribution function rather than independent values on a momentum grid. Use the mixture parameters inside a differentiable Boltzmann collision operator, so training directly enforces the interaction mechanism and exposes the relaxation spectrum responsible for ballistic-to-hydrodynamic crossover.
