A Cable-Driven Home-Based Upper-Limb Rehabilitation Robot for ADL-Based Training in Unstructured Daily Environments

RA-L 2026

This paper presents a portable, cable-driven upper-limb rehabilitation robot designed for home-based activities of daily living (ADLs). The proposed robot is intended to assist hemiplegia patients with ADL-based rehabilitation, such as drinking water from a cup, in home settings. The robot features

State-Dependent Safety Failures in Multi-Turn Language Model Interaction

ICML 2026poster

Safety alignment in large language models is typically evaluated under isolated queries, yet real-world use is inherently multi-turn. Although multi-turn jailbreaks are empirically effective, the structure of conversational safety failure remains insufficiently understood. In this work, we study saf…

EMO-RL: Emotion-Rule-Based Reinforcement Learning Enhanced Audio-Language Model for Generalized Speech Emotion Recognition

EMNLP 2025

Although large audio-language models (LALMs) have demonstrated remarkable capabilities in audio perception, their performance in affective computing scenarios, particularly in emotion recognition, reasoning, and subtle sentiment differentiation, remains suboptimal. Recent advances in reinforcement l

Exploring Scene Affinity for Semi-Supervised LiDAR Semantic Segmentation

CVPR 2025poster

This paper explores scene affinity (AIScene), namely intra-scene consistency and inter-scene correlation, for semi-supervised LiDAR semantic segmentation in driving scenes. Adopting teacher-student training, AIScene employs a teacher network to generate pseudo-labeled scenes from unlabeled data, whi…

IDEAW: Robust Neural Audio Watermarking with Invertible Dual-Embedding

EMNLP 2024main

The audio watermarking technique embeds messages into audio and accurately extracts messages from the watermarked audio. Traditional methods develop algorithms based on expert experience to embed watermarks into the time-domain or transform-domain of signals. With the development of deep neural netw…

Knowledge Triplets Derivation from Scientific Publications via Dual-Graph Resonance

COLING 2024main

Scientific Information Extraction (SciIE) is a vital task and is increasingly being adopted in biomedical data mining to conceptualize and epitomize knowledge triplets from the scientific literature. Existing relation extraction methods aim to extract explicit triplet knowledge from documents, howev…

Hierarchical Supervision and Shuffle Data Augmentation for 3D Semi-Supervised Object Detection

CVPR 2023poster

State-of-the-art 3D object detectors are usually trained on large-scale datasets with high-quality 3D annotations. However, such 3D annotations are often expensive and time-consuming, which may not be practical for real applications. A natural remedy is to adopt semi-supervised learning (SSL) by lev…
