Multilabel micro recall counts samples instead of labels · case 02
Multilabel micro recall counts samples instead of labels.
Case contract
Return total true label instances divided by total actual label instances; empty actual label sets yield 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 |
|---|---|---|---|
| multiple labels | 0.5 | 0.75 | Failed |
