RoboSemanticBench: Diagnosing Semantic Grounding in Action Prediction for VLA Models

Bin Yu, Yao Zhang, Haishan Liu +9

Vision-language-action (VLA) models are built on the premise that semantic understanding from pretrained language or vision-language backbones should guide robot action prediction.…

HunterAgent: Neuro-Symbolic Attack Trace Reconstruction under Anti-Forensics

Guangze Zhao, Yongzheng Zhang, Weilin Gai +3

Modern alert-triage systems reduce SOC burden by filtering false positives, but flagging a high-risk alert is only the start of incident response. Threat hunting requires reconstru…

FrameSkip: Learning from Fewer but More Informative Frames in VLA Training

Bin Yu, Shijie Lian, Xiaopeng Lin +8

Vision-Language-Action (VLA) policies are commonly trained from dense robot demonstration trajectories, often collected through teleoperation, by sampling every recorded frame as i…

3D-Mix for VLA: A Plug-and-Play Module for Integrating VGGT-based 3D Information into Vision-Language-Action Models

Bin Yu, Shijie Lian, Xiaopeng Lin +8

Vision-Language-Action (VLA) models leverage Multimodal Large Language Models (MLLMs) for robotic control, but recent studies reveal that MLLMs exhibit limited spatial intelligence…

TwinBrainVLA: Unleashing the Potential of Generalist VLMs for Embodied Tasks via Asymmetric Mixture-of-Transformers

Bin Yu, Shijie Lian, Xiaopeng Lin +8

The fundamental premise of Vision-Language-Action (VLA) models is to harness the extensive general capabilities of pre-trained Vision-Language Models (VLMs) for generalized embodie…

TrajSelector: Harnessing Latent Representations for Efficient and Effective Best-of-N in Large Reasoning Model

Bin Yu, Xinming Wang, Shijie Lian +6

Large language models (LLMs) have shown remarkable progress in complex reasoning tasks, largely enabled by test-time scaling (TTS) paradigms that allocate additional compute during…
