SSOG-Attention introduces a novel attention mechanism using Sum of Separable Gaussians to achieve sub-quadratic complexity, outperforming or matching SDPA with faster convergence and improved efficiency.

PRISM introduces a theory for designing reference processes in Schrödinger bridge models, showing that under finite computational budgets the optimal reference noise spectrum is determined by the sensor's information destruction spectrum. Experiments confirm the theory in Gaussian settings and identify where real images deviate.
