Autonomous UAV–Quadruped Docking in Complex Terrains Via Active Posture Alignment and Constraint-Aware Control

ICRA 2026poster

Autonomous docking between Unmanned Aerial Vehicles (UAVs) and ground robots is essential for heterogeneous systems, yet most existing approaches target wheeled platforms whose limited mobility constrains exploration in complex terrains. Quadruped robots offer superior adaptability but undergo frequ…

Beyond Single Labels: Improving Conversational Recommendation through LLM-Powered Data Augmentation

ACL 2025long

Conversational recommender systems (CRSs) enhance recommendation quality by engaging users in multi-turn dialogues, capturing nuanced preferences through natural language interactions. However, these systems often face the false negative issue, where items that a user might like are incorrectly labe…

STR-Saliency: Decomposition-based Perturbations to Generate Saliency Maps for Temporal Black-box Model Interpretation

ICASSP 2025accepted

The interpretability of deep black-box temporal models is crucial in modern machine learning. Identifying crucial time steps and temporal patterns is an important way in understanding how a black-box model makes a decision on a time series instance. Saliency methods are widely used for the interpret…

HAZARD Challenge: Embodied Decision Making in Dynamically Changing Environments

ICLR 2024poster

Recent advances in high-fidelity virtual environments serve as one of the major driving forces for building intelligent embodied agents to perceive, reason and interact with the physical world. Typically, these environments remain unchanged unless agents interact with them. However, in real-world sc…
