Any-Diffusion: Unified Multimodal Understanding and Generation with Masked Discrete Diffusion

ICML 2026poster

While recent multimodal large language models (MLLMs) have made impressive strides, they mostly employ a conventional autoregressive architecture as their backbone, leaving significant room for exploring effective and efficient alternatives in architectural design. Meanwhile, recent studies have suc…

SX-Stitch: An Efficient VMS-UNet Based Framework for Intraoperative Scoliosis X-Ray Image Stitching

ICASSP 2025accepted

In scoliosis surgery, the limited field of view of the C-arm Xray machine restricts the surgeons’ holistic analysis of spinal structures. This paper presents an end-to-end efficient and robust intraoperative X-ray image stitching method for scoliosis surgery, named SX-Stitch. The method is divided i…

VITA-1.5: Towards GPT-4o Level Real-Time Vision and Speech Interaction

NeurIPS 2025spotlight

Recent Multimodal Large Language Models (MLLMs) have typically focused on integrating visual and textual modalities, with less emphasis placed on the role of speech in enhancing interaction. However, speech plays a crucial role in multimodal dialogue systems, and implementing high-performance in bot…

VITA-Audio: Fast Interleaved Audio-Text Token Generation for Efficient Large Speech-Language Model

NeurIPS 2025poster

With the growing requirement for natural human-computer interaction, speech-based systems receive increasing attention as speech is one of the most common forms of daily communication. However, the existing speech models still experience high latency when generating the first audio token during stre…

Speech Self-Supervised Learning Using Diffusion Model Synthetic Data

ICML 2024oral

While self-supervised learning (SSL) in speech has greatly reduced the reliance of speech processing systems on annotated corpora, the success of SSL still hinges on the availability of a large-scale unannotated corpus, which is still often impractical for many low-resource languages or under privac…

Listen, Decipher and Sign: Toward Unsupervised Speech-to-Sign Language Recognition

ACL 2023findings

Existing supervised sign language recognition systems rely on an abundance of well-annotated data. Instead, an unsupervised speech-to-sign language recognition (SSR-U) system learns to translate between spoken and sign languages by observing only non-parallel speech and sign-language corpora. We pro…

ContentVec: An Improved Self-Supervised Speech Representation by Disentangling Speakers

ICML 2022spotlight

Self-supervised learning in speech involves training a speech representation network on a large-scale unannotated speech corpus, and then applying the learned representations to downstream tasks. Since the majority of the downstream tasks of SSL learning in speech largely focus on the content inform…
