Momentum dampening scales the carried buffer · case 03
Momentum dampening scales the carried buffer.
Case contract
v_next=mu*v+(1-dampening)*g; return [p-lr*v_next,v_next].
Why this case matters
Optimizer implementations must associate each parameter with its own mathematically specified update state.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| retained velocity | [4.5, 3.5] | [3, 5] | Failed |
