A Differentiable 3D Scene Graph Metric via Contextual Hellinger Triplet Geometry
U-Chae Jun, Yoonhyuk Choi, Jiwoo Kang
3D scene graph prediction is commonly supervised with local object and predicate classification losses. Although effective for slot-wise label prediction, this formulation does not…

SWORD: Scene-Grounded Wasserstein Object-Relation Distance for 3D Scene Graph Prediction
U-Chae Jun, Jaeeun Ko, Yoonhyuk Choi +1
3D scene graph prediction is commonly optimized with object-node and relation-edge classification losses. These objectives encourage exact object and relation label recovery, but t…
