What the math gives to ML

The paper contributes a nonstandard control mechanism: adaptive prescribed-time stabilization of a continuous-time generalized Bellman-Ford/min-consensus flow, with convergence guaranteed by a user-selected deadline rather than only asymptotically. Its transferable asset is a deadline-aware adaptive gain law that avoids the usual singular gain proportional to $(T-t)^{-1}$. A promising neural-network transfer is a prescribed-time optimizer whose gain is adapted online so that a Lyapunov error reaches a target tolerance by a specified training time. The key falsifiable signature is a predictable relationship between the gain, the deadline, and the transformed loss decay.

Deadline-Adaptive Gradient Flow

Replace a constant learning rate by an adaptive prescribed-time gain calibrated to a user-specified deadline. Apply the mechanism to a nonnegative training Lyapunov error such as the loss under a local Polyak-Lojasiewicz condition, or to disagreement errors in distributed training, so that the error reaches a target tolerance by time T without using a singular learning rate.
