A new research paper investigates the limitations of diffusion models in generating multiple objects within images. The study introduces a controlled dataset generation framework called 'mosaic' to analyze concept generalization and compositional generalization. Findings indicate that scene complexity, rather than data imbalance, is the primary factor affecting multi-object generation, with counting tasks proving particularly difficult in low-data scenarios.
