Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| Use point-moving deformation with PMP-Net instead of the strongest reported baseline | Completion3D · Completion3D | per-point L2 Chamfer distance × 10^4: 10.64 -> 9.23 | Helped |
| Use point-moving deformation with PMP-Net instead of the strongest reported baseline | PCN · PCN | per-point L1 Chamfer distance × 10^3: 8.51 -> 8.66 | Hurt |
| Add the RPA module rather than removing it (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 11.95 -> 11.58 | Helped |
| Replace element-wise addition with RPA (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 12.23 -> 11.58 | Helped |
| Replace RNN with RPA (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 12.12 -> 11.58 | Helped |
| Replace LSTM with RPA (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 11.99 -> 11.58 | Helped |
| Replace GRU with RPA (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 11.87 -> 11.58 | Helped |
| Add PMP loss rather than training with Chamfer distance alone (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 13.66 -> 11.58 | Helped |
| Use 2 or 3 deformation steps instead of 1 (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 12.26 -> 11.90; 12.26 -> 11.58 | Helped |
| Use 4 deformation steps instead of 3 (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 11.58 -> 11.67 | Hurt |
| Decrease searching radius across steps instead of keeping it constant (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 12.01 -> 11.58 | Helped |
| Use the sharper radius schedule [1.0,0.1,0.01] instead of [1.0,0.5,0.25] (ablation) | PMP-Net · Completion3D validation (plane, chair, car, table) | average Chamfer distance: 11.77 -> 11.58 | Helped |
