A stained-glass studio watches training loss keep falling while the held-out loss turns upward. What training-loop idea fits ending the run when the unused split no longer improves?
Select an answer to reveal the explanation.
Short Explanation
When practice keeps getting easier but the spare pane set gets worse, it is time to put the tools down. Early stopping ends the run using that held-out signal. It is a training-loop guardrail, not a metric-shopping exercise.
Full Explanation
Early stopping monitors a held-out loss or similar validation signal and ends training when that signal no longer improves, even if training loss continues to fall. That practice helps limit overfitting. It is defined by the training loop’s use of a held-out check, not by inventing unrelated civic KPIs.
