Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Replace Moco pre-training with UP-ReID pre-training | MGN with ResNet50 · CUHK03 | mAP: 74.7 -> 85.3 | Helped |
| Replace Moco pre-training with UP-ReID pre-training | SpCL · Market1501 (M, unsupervised) | mAP: 72.2 -> 75.1 | Helped |
| Add global consistency constraint (ablation) | UP-ReID pre-training · CUHK03 | mAP: 74.7 -> 79.1(+4.4) | Helped |
| Add intrinsic contrastive constraint (ablation) | UP-ReID pre-training · CUHK03 | mAP: 74.7 -> 81.4(+6.7) | Helped |
| Add both global consistency and intrinsic contrastive constraints (ablation) | UP-ReID pre-training · CUHK03 | mAP: 74.7 -> 85.3(+10.6) | Helped |
| Add hard mining to ICC (ablation) | UP-ReID pre-training · CUHK03 | mAP: 80.7 -> 85.3 | Helped |
| Set patch count to M=8 instead of M=4 or M=12 (ablation) | UP-ReID ICC · CUHK03 | mAP: 81.3 -> 85.3; 80.7 -> 85.3 | Helped |
| Use random or online positive patch selection instead of horizontally symmetric positives (ablation) | UP-ReID ICC · LUPerson pre-training | patch-wise contrastive loss convergence | Hurt |
