What the math gives to ML

The paper gives a constructive way to preserve convex-order comparisons through Euler-discretized stochastic dynamics. This can transfer to stochastic neural representations or mixture-of-experts by coupling expert states through a graphon-like interaction matrix and controlling how uncertainty grows while preserving the representation mean. The practical mechanism is an empirical convex-order regularizer built from finitely many convex probes, combined with an Euler stochastic residual update. This is more promising for calibration, robustness, and controlled exploration than for raw speed.

Convex-order stochastic expert layer

Replace a deterministic mixture-of-experts residual block with K population-indexed stochastic expert states coupled through a graphon matrix. The layer uses a shared drift and expert-dependent diffusion, while an empirical convex-order penalty makes later representations more dispersed than a reference representation without permitting a mean shift.
