FA-100014 / Evaluation metric aggregation / Member archive
Sample weights are applied only to correct rows · case 04
Sample weights are applied only to correct rows.
Case contract
Return weighted accuracy for aligned labels and nonnegative weights; zero total weight yields 0.
Why this case matters
A small explicit evaluation contract makes aggregation behavior reproducible across labeled examples.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| unequal weights | 2.0 | 0.8 | Failed |
