Researchers have developed Velocityformer, a novel equivariant graph transformer architecture designed to enhance the reconstruction of galaxy velocities for cosmological studies. This model specifically addresses the broken symmetry inherent in observational data, leading to a significant 35% improvement in the correlation coefficient compared to standard linear theory baselines. Velocityformer demonstrates high data efficiency, achieving accuracy with minimal simulations, and shows strong generalization capabilities across different input geometries and cosmological parameters.
