What the math gives to ML

The paper provides a transferable event-triggered estimation mechanism: sensors communicate only when regressor-driven local information changes sufficiently, while a gradient estimator retains global exponential convergence under aggregate persistent excitation. Its important asset is that triggering does not require access to the current parameter estimate, making it compatible with communication-limited federated or distributed neural training. The direct neural-network transfer is an event-triggered optimizer for a shared linear head or local Jacobian statistics, with a stale-information bound controlling the perturbation introduced by suppressed updates. The key falsifiable prediction is a communication-versus-convergence transition: below a threshold determined by estimator gain and excitation, convergence is retained, while larger thresholds produce a residual error or instability.

Regressor-triggered federated gradient updates

Replace periodic client-to-server updates for an online neural-network head with event-triggered transmissions based only on local feature regressors and sufficient statistics, not on the current global parameter estimate. Each client transmits when its local Gram matrix or feature-response statistic changes enough that using the previously transmitted value would violate a prescribed perturbation bound. This should preserve exponential convergence in the strongly excited linear-head regime…
