Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Replace full-class proxy comparisons with batch-selected proxy pairs | PCR · Split CIFAR100, buffer 1000 | final accuracy rate: 23.1 ±0.8 -> 25.6 ±0.6 | Helped |
| Replace full-class proxy comparisons with batch-selected proxy pairs | PCR · Split MiniImageNet, buffer 1000 | final accuracy rate: 20.3 ±1.3 -> 24.2 ±0.9 | Helped |
| Add selected anchor-to-proxy pairs, excluding duplicate pairs (ablation) | ER · Split CIFAR100, buffer 1000 | final accuracy rate: 17.6 ±0.9 -> 25.5 ±0.6 | Helped |
| Keep duplicate selected anchor-to-proxy pairs (ablation) | ER+A · Split CIFAR100, buffer 1000 | final accuracy rate: 25.5 ±0.6 -> 25.6 ±0.6 | Helped |
| Add SCR's original anchor-to-sample pairs alongside proxy pairs (ablation) | PCR · Split CIFAR100, buffer 1000 | final accuracy rate: 25.6 ±0.6 -> 24.1 ±0.5 | Hurt |
