SD-GRPO: Verifiable Segment Decomposition for Long-Form Vision-Language Generation
Hyunwoong Kim, Seongeun Lee, Hannah Yun +2
Group Relative Policy Optimization (GRPO) and its variants, originally developed for Large Language Models (LLMs), have recently been applied to Multimodal LLMs and produced strong…
GLINT: Sparsely Gated Vision-Language Alignment for Fine-Grained Radiology Representations
Jonggwon Park, Seongeun Lee, Junhyun Park +6
Vision-language models (VLMs) for radiology have emerged as a scalable paradigm by leveraging image-report pairs naturally produced in clinical workflows. However, this pairing rev…
SSTL: Self-Sensing Tendon Loop for Hysteresis Modeling and Compensation in Tendon-Sheath Mechanisms
Myeongbo Park, Junhyun Park, Ihsan Ullah +2
Flexible endoscopic robots enable minimally invasive access through natural orifices, but their control accuracy is limited by configuration-dependent hysteresis in the tendon-shea…
MarUco: A Markerless 6D Pose Estimation Framework for Closed-Loop Control of Surgical Continuum Manipulators
Junhyun Park, Chunggil An, Myeongbo Park +3
Flexible endoscopic continuum manipulators offer high dexterity and access to complex anatomy, but nonlinear hysteresis limits feedforward control accuracy. Closed-loop control can…
Vibration-Assisted Hysteresis Mitigation for Achieving High Compensation Efficiency
Myeongbo Park, Chunggil An, Junhyun Park +2
Tendon-sheath mechanisms (TSMs) are widely used in minimally invasive surgical (MIS) applications, but their inherent hysteresis-caused by friction, backlash, and tendon elongation…
OFF-CLIP: Improving Normal Detection Confidence in Radiology CLIP with Simple Off-Diagonal Term Auto-Adjustment
Junhyun Park, Chanyu Moon, Donghwan Lee +2
Contrastive Language-Image Pre-Training (CLIP) has enabled zero-shot classification in radiology, reducing reliance on manual annotations. However, conventional contrastive learnin…
