Measured effects reported in the paper
| What was changed | Where | Measured | Effect |
|---|---|---|---|
| allow multiple predicate labels per object pair instead of single-predicate classification (ablation) | 3DSSG scene graph prediction · 3DSSG | R@3 predicate prediction: 0.42 -> 0.89 | Helped |
| allow multiple predicate labels per object pair instead of single-predicate classification (ablation) | 3DSSG scene graph prediction · 3DSSG | R@50: 0.37 -> 0.40 | Mixed |
| predict object classes from GCN features instead of PointNet features (ablation) | Multi Predicate scene graph predictor · 3DSSG | R@5 object classification: 0.68 -> 0.60 | Hurt |
| add semantic relationships to node-based graph matching (ablation) | 3D-3D scene retrieval with ground-truth graphs · 3D-3D changing-scene retrieval | Top-1: 0.89 -> 0.95 | Helped |
| use Szymkiewicz-Simpson similarity instead of Jaccard similarity (ablation) | 2D-3D scene retrieval with ground-truth graphs · 2D-3D changing-scene retrieval | Top-1: 0.49 -> 0.98 | Helped |
| add semantic relationships to node-only matching with proposed predicted graphs (ablation) | 2D-3D scene retrieval · 2D-3D changing-scene retrieval | Top-1: 0.17 -> 0.13 | Hurt |
