Overfitting a development set used for model tuning

What most clearly indicates that a manually inspected dev slice has been over-tuned during error analysis?

Inspecting a manually reviewed validation set can make you adapt to that set more quickly than if you never looked at its examples.

Keeping a Reviewed Subset Separate from a Hidden Check Set

Match each validation-set concept to its description in a reviewed-vs-reserved split.

Order the steps for checking whether repeated manual review is causing overfitting to a reviewed validation subset.

What is the most likely conclusion when manual review keeps pushing one dev set score far above another?

In the Eyeball/Blackbox approach, the Blackbox dev set is checked manually during routine error analysis.

If the Eyeball dev set improves much faster than the Blackbox dev set, you have _____ the Eyeball dev set.

Match each performance pattern with the most appropriate interpretation when comparing a hand-reviewed set with a separate hidden set.
