PACE: Physics Augmentation for Coordinated End-To-End Reinforcement Learning Toward Versatile Humanoid Table Tennis

ICRA 2026poster

Humanoid table tennis (TT) demands rapid perception, proactive whole-body motion, and agile footwork under strict timing—capabilities that remain difficult for end-to-end control policies. We propose a reinforcement learning (RL) framework that maps ball-position observations directly to whole-body …

DRCap: Decoding CLAP Latents with Retrieval-Augmented Generation for Zero-shot Audio Captioning

ICASSP 2025accepted

While automated audio captioning (AAC) has made notable progress, traditional fully supervised AAC models still face two critical challenges: the need for expensive audio-text pair data for training and performance degradation when transferring across domains. To overcome these limitations, we prese…

Enhancing Speech-to-Speech Dialogue Modeling with End-to-End Retrieval-Augmented Generation

EMNLP 2025

End-to-end speech-to-speech (S2S) dialogue systems have recently garnered increasing research attention for their lower latency and more natural integration of nonverbal cues such as emotion and speaker identity. However, these systems face key challenges, particularly in incorporating external know

Leveraging Perturbation Robustness to Enhance Out-of-Distribution Detection

CVPR 2025poster

Out-of-distribution (OOD) detection is the task of identifying inputs that deviate from the training data distribution. This capability is essential for the safe deployment of deep computer vision models in open-world environments. In this work, we propose a post-hoc method, Perturbation-Rectified O…
