TIGeR: Tool-Integrated Geometric Reasoning in Vision-Language Models for Robotics

ICRA 2026poster

Vision-Language Models (VLMs) have shown remarkable capabilities in spatial reasoning, yet they remain fundamentally limited to qualitative assessments and lack the computational precision required for real-world robotics. Current approaches fail to leverage metric information from depth sensors and…

AGFSync: Leveraging AI-Generated Feedback for Preference Optimization in Text-to-Image Generation

AAAI 2025technical

Text-to-Image (T2I) diffusion models have achieved remarkable success in image generation. Despite their progress, challenges remain in both prompt-following ability, image quality and lack of high-quality datasets, which are essential for refining these models. As acquiring labeled data is costly,…

Medical MLLM Is Vulnerable: Cross-Modality Jailbreak and Mismatched Attacks on Medical Multimodal Large Language Models

AAAI 2025technical

Security concerns related to Large Language Models (LLMs) have been extensively explored; however, the safety implications for Multimodal Large Language Models (MLLMs), particularly in medical contexts (MedMLLMs), remain inadequately addressed. This paper investigates the security vulnerabilities of…

RoboRefer: Towards Spatial Referring with Reasoning in Vision-Language Models for Robotics

NeurIPS 2025poster

Spatial referring is a fundamental capability of embodied robots to interact with the 3D physical world. However, even with the powerful pretrained VLMs, recent approaches are still not qualified to accurately understand the complex 3D scenes and dynamically reason about the instruction-indicated lo…
