Action-Sketcher: From Reasoning to Action via Visual Sketches for Robotic Manipulation

CVPR 2026

Long-horizon robotic manipulation is increasingly important for real-world deployment, requiring spatial disambiguation in complex layouts and temporal resilience under dynamic interaction. However, existing end-to-end and hierarchical Vision-Language-Action (VLA) policies often rely on text-only cu

General Covariant Action Modeling: Constructing Generalized Manifolds via Spatio-Temporal Decoupling

ICML 2026poster

Achieving robust generalization from limited data is a central challenge in embodied intelligence. Prevailing methods fail by regressing absolute coordinates, which violates the principle of general covariance. Theoretically, this conflates the intrinsic task geometry with rigid execution patterns, …

General Process Reward Modeling for Robotic Reinforcement Learning

CVPR 2026

The primary obstacle for applying reinforcement learning (RL) to real-world robotics is the design of effective reward functions. While recently learning-based Process Reward Models (PRMs) are a promising direction, they are often hindered by two fundamental limitations: their reward models lack ste

LAST: Bridging Vision-Language and Action Manifolds via Gromov-Wasserstein Alignment

ICML 2026poster

We formulate the learning of generalist Vision-Language-Action (VLA) models as a Gromov-Wasserstein alignment problem, aiming to map semantically similar VL embeddings to physically similar motion primitives. However, solving this is challenging due to the mathematical heterogeneity between the doma…

Scaling Up AI-Generated Image Detection with Generator-Aware Prototypes

CVPR 2026

The pursuit of a universal AI-generated image (AIGI) detector often relies on aggregating data from numerous generators to improve generalization. However, this paper identifies a paradoxical phenomenon we term the "Benefit then Conflict" dilemma, where detector performance stagnates and eventually
