Rectified Schr\"odinger Bridge Matching for Few-Step Visual Navigation

Wuyang Luan et al. · arXiv:2604.05673v1 Announce Type: cross Abstract: Visual navigation is a core challenge in Embodied AI, requiring autonomous agents to translate high-dimensional sensory observations into continuous, long-horizon action trajectories. While generative policies based on diffusion models and Schr\"odinger Bridges (SB) effectively capture multimodal action distributions, they require dozens of integration steps due to high-variance stochastic transport, posing a critical barrier for real-time roboti

Discrete Flow Matching Policy Optimization

Maojiang Su et al. · 提出离散流匹配策略优化框架 DoMinO,统一了多种策略梯度方法。理论上有价值,但主要针对离散动作空间,与当前连续控制为主的 VLA 主流略有距离。
