Action-aware Dynamic Pruning for Efficient Vision-Language-Action Manipulation

ICLR 2026poster

Robotic manipulation with Vision-Language-Action models requires efficient inference over long-horizon multi-modal context, where attention to dense visual tokens dominates computational cost. Existing methods optimize inference speed by reducing visual redundancy within VLA models, but they overloo…

Affordance Field Intervention: Enabling VLAs to Escape Memory Traps in Robotic Manipulation

CVPR 2026

Vision-Language-Action (VLA) models have shown great performance in robotic manipulation by mapping visual observations and language instructions directly to actions. However, they remain brittle under distribution shifts: when test scenarios change, VLAs often reproduce memorized trajectories inste

Seeing Realism from Simulation: Efficient Video Transfer for Vision-Language-Action Data Augmentation

ICML 2026poster

Vision-language-action (VLA) models typically rely on large-scale real-world videos, whereas simulated data, despite being inexpensive and highly parallelizable to collect, often suffers from a substantial visual domain gap and limited environmental diversity, resulting in weak real-world generaliza…

VLA-Cache: Efficient Vision-Language-Action Manipulation via Adaptive Token Caching

NeurIPS 2025poster

Vision-Language-Action (VLA) models have demonstrated strong multi-modal reasoning capabilities, enabling direct action generation from visual perception and language instructions in an end-to-end manner. However, their substantial computational cost poses a challenge for real-time robotic control,…
