FA-98882 / Gradient accumulation weighting / Member archive
Vector coordinates use the number of microbatches as denominator · case 02
Vector coordinates use the number of microbatches as denominator.
Case contract
Equal-width vectors contain coordinatewise summed gradients. Divide every coordinate by the same total example count; empty input returns [].
Why this case matters
A deterministic toy model isolates one local accumulation contract.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| two coordinates | [14.0, 12.0] | [3.5, 3] | Failed |
