Optimal feedback control under stepwise equilibration and partial observation

What the math gives to ML

The paper provides a constructive reduction of a partially observed nonequilibrium control problem to a finite-horizon Bellman recursion when the system re-equilibrates between interventions. Its transferable asset is an information-aware control rule that trades progress toward a target against exploitation of noisy state estimates, while accounting for a fixed cost per intervention and an endpoint constraint. In neural-network training, this suggests treating parameter updates as controlled interventions, estimating a low-dimensional uncertainty state from recent stochastic gradients, and using a finite-horizon dynamic program to choose update magnitudes and whether another update is worthwhile.
