The paper's transferable asset is a finite-horizon alternative to confidence sequences: instead of protecting against infinitely many future peeks, it allocates error only across a predeclared maximum of H monitoring times. This yields tighter simultaneous uncertainty bands while retaining asymptotic coverage under repeated inspection. In neural-network workflows, the most direct use is statistically controlled early stopping or checkpoint selection on a noisy validation stream with a known evaluation budget. The implementation should calibrate a single finite-horizon boundary for the planned number of checks, rather than repeatedly applying pointwise confidence intervals or using an unnecessarily conservative infinite-horizon bound.
Replace pointwise validation tests or infinite-horizon confidence sequences with a confidence horizon covering exactly the next H validation checks. Use the resulting simultaneous band to stop evaluating or stop training once the probability of further improvement falls below a target threshold, while spending less statistical slack than an anytime-valid method.
