What the math gives to ML

The paper gives a constructive reduction of observables in Gaussian random potentials to the joint distribution of local Taylor coefficients, whose covariances are determined by derivatives of the potential Green function. It connects local curvature and barrier statistics to thermal and quantum activation rates, relating observable escape dynamics to disorder in the landscape. A transferable neural-network mechanism is curvature- and escape-rate-controlled Langevin training: estimate loss-landscape barriers and adapt optimizer noise to maintain a prescribed basin-escape rate. The main falsifiable prediction is an Arrhenius relation between escape frequency and inverse effective temperature, with a measurable trapping-to-exploration transition.

Activation-Calibrated Langevin Optimizer

Treat stochastic gradient training as motion in a random potential given by the neural-network loss, and use local curvature and barrier estimates to control injected Langevin noise. Instead of applying a fixed temperature, adapt the optimizer noise so that the observed escape rate from a basin matches a target rate predicted by thermal activation. This should reduce premature trapping in sharp minima while avoiding destabilization from excessive gradient noise.
