SEES: A Self-Evolving Embodied System via Failure-Guided VLA Policy Adaptation

Recent vision-language-action (VLA) policies demonstrate promising generalization across diverse short-horizon tasks. However, they remain unreliable on long-horizon tasks, partly because the large-scale training data is biased toward single-stage manipulation tasks that are cheaper to demonstrate. A single weak atomic...

High-Quality Exposure Correction With Diffusion-Based Image Generation Priors

This paper proposes DPEC (Diffusion Prior-based Exposure Correction), a novel framework for image exposure correction that utilizes diffusion-based image generation priors encapsulated in pre-trained large-scale diffusion models, and seamlessly combines the strengths of diffusion models and regression models.
