Rectified Schrödinger Bridge Matching for Few-Step Visual Navigation
A new framework called Rectified Schrödinger Bridge Matching (RSBM) has been introduced by researchers to enhance few-step visual navigation in Embodied AI. This approach leverages a common velocity-field structure shared by standard Schrödinger Bridges and deterministic Optimal Transport, regulated by a single entropic parameter. It demonstrates that the functional form of the conditional velocity field remains consistent throughout the entire regularization spectrum, facilitating efficient navigation with fewer integration steps. This innovation tackles the significant challenge of high-variance stochastic transport in diffusion models and Schrödinger Bridges, which typically necessitate numerous steps for real-time robotic control. The findings are detailed in a paper available on arXiv with the ID 2604.05673.
