add mixup augmentation (alpha=0.2, p=0.5)
Measurements
| Metric | BaselineThe benchmark measurement of the unmodified code | CandidateThe code with the proposed optimization applied | Candidate/Parent ΔThe performance change from baseline to candidate |
|---|
| val_acc (%) primary | 0.988 % (n=1) | 0.984 % (n=1) | -0.40% REGRESSED |
Annotations
| hypothesis | add mixup augmentation (alpha=0.2, p=0.5) |
| next_action_hint | try lower alpha or combined with other tweaks |
| rollback_reason | val_acc 0.984 < best 0.988, close but not improvement |
| Base CommitThe starting commit before the optimization was applied | 5bb1919633791dc9cfd6d4e69afc936452b5310d |
| Candidate CommitThe code with the proposed optimization applied | no new code recorded — metadata only |
