New diffusion model generates complex 3D scene graphs

Researchers have developed a novel autoregressive diffusion model capable of generating high-level concepts within 3D scene graphs. This unified approach jointly learns graph structure and spatial node features, enabling bottom-up construction of complete 3D scene graphs from observed geometric primitives. The model demonstrates superior performance across various datasets compared to existing learning-based and random baselines, and introduces an adaptation of the Fused Gromov--Wasserstein distance for evaluating generated graphs.
