E³SAM2: Entropy-Aware and Edge-Guided Adaptation of SAM2 for Echocardiography Video Segmentation

AAAI 2026technical

Foundation segmentation models, such as SAM and its video-oriented variant SAM2, have achieved remarkable success in natural image and video segmentation. However, their direct application to echocardiography video is challenged by structural uncertainty arising from severe speckle noise and blurry

S${3}$aDPWo: Spatial-, Semantic-, and Shape-Aware Diffusion Policy Toward Autonomous Wound Repair

RA-L 2026

Imitation learning (IL) offers a promising pathway for enabling surgical robots to perform autonomous wound repair. However, existing methods often neglect spatial semantics and wound-shape information, leading to poor generalization and low success rates. This paper presents the <bold>S</bold>patia

EPIC: Efficient Position-Independent Caching for Serving Large Language Models

ICML 2025poster

Large Language Models (LLMs) show great capabilities in a wide range of applications, but serving them efficiently becomes increasingly challenging as requests (prompts) become more complex. Context caching improves serving performance by reusing Key-Value (KV) vectors, the intermediate representati…

DSVP: Dual-Stage Viewpoint Planner for Rapid Exploration by Dynamic Expansion

IROS 2021poster

We present a method for efficiently exploring highly convoluted environments. The method incorporates two planning stages - an exploration stage for extending the boundary of the map, and a relocation stage for explicitly transiting the robot to different sub-areas in the environment. The exploratio…

Sensor Embedded Soft Fingertip for Precise Manipulation and Softness Recognition

RA-L 2021

Up to this day, precise manipulation still relies on human hands, which benefits from the rich neural sensing in the fingertips. For robotic hands, force perception, recognizing the softness of objects, and detecting slip can significantly improve the grasping and manipulating abilities. However, it
