D-Loop: Looped Diffusion Drafting for Speculative Decoding

Kecheng Chen, Yuyang He, Cheng Gong +8

Block diffusion accelerates speculative decoding by drafting multiple tokens in one forward pass. However, each position predicts a marginal distribution without observing earlier…

How Should Diffusion Language Models Edit Code?

Xijia Tao, Ziru Liu, Shansan Gong +7

Code editing requires a model to decide where to make changes, generate the new content, and preserve everything else. We study how masked diffusion language models divide these re…

RedEvoAgent: Automatic Red-Teaming Agent with Experience-Driven Skill Evolution

Junjie Zhang, Hui Liu, Kecheng Chen +3

LLM-based agents are increasingly deployed in product-level execution harnesses, where jailbreaks can trigger harmful tool use and persistent state changes, creating greater risks…

LiST: Local-Simplex Test-Time LoRA Fusion

Yihua Shao, Jia Li, Siyu Chen +12

Task-specific LoRA adapters offer a modular way to specialize large language and vision-language models. However, existing adapter composition methods are mostly static and cannot…

LUMI: Tokenizer-Agnostic LLM-Based Lossless Image Compression

Chris Xing Tian, Chengkai Wu, Ziyu Wang +6

Large language model (LLM)-based lossless image compression methods typically represent pixel data through the native text interface of a pretrained model, converting pixel values…

SoftSkill: Behavioral Compression for Contextual Adaptation

Xijia Tao, Yihua Teng, Xinyu Fu +6

Natural-language skills let agents reuse task knowledge, yet deploying a long Markdown document makes the model interpret that knowledge anew on every call. We ask whether the beha…

Self-Distilled Trajectory-Aware Boltzmann Modeling: Bridging the Training-Inference Discrepancy in Diffusion Language Models

Kecheng Chen, Ziru Liu, Xijia Tao +9

Diffusion Language Models (DLMs) have recently emerged as a promising alternative to autoregressive language models, offering stronger global awareness and highly parallel generati…

Beyond Heuristic Prompting: A Concept-Guided Bayesian Framework for Zero-Shot Image Recognition

Hui Liu, Kecheng Chen, Jialiang Wang +3

Vision-Language Models (VLMs), such as CLIP, have significantly advanced zero-shot image recognition. However, their performance remains limited by suboptimal prompt engineering an…

Efficient Test-Time Adaptation through Latent Subspace Coefficients Search

Xinyu Luo, Jie Liu, Kecheng Chen +6

Real-world deployment often exposes vision models to distribution shifts, making test-time adaptation (TTA) important for reliable prediction. Existing TTA methods can be difficult…

Disentangling Instruction Influence in Diffusion Transformers for Parallel Multi-Instruction-Guided Image Editing

Hui Liu, Bin Zou, Suiyun Zhang +3

Instruction-guided image editing enables users to specify modifications using natural language, offering more flexibility and control. Among existing frameworks, Diffusion Transfor…

Large Language Models for Lossless Image Compression: Next-Pixel Prediction in Language Space is All You Need

Kecheng Chen, Pingping Zhang, Hui Liu +6

We have recently witnessed that ``Intelligence" and `` Compression" are the two sides of the same coin, where the language large model (LLM) with unprecedented intelligence is a ge…

Test-time adaptation for image compression with distribution regularization

Kecheng Chen, Pingping Zhang, Tiexin Qin +3

Current test- or compression-time adaptation image compression (TTA-IC) approaches, which leverage both latent and decoder refinements as a two-step adaptation scheme, have potenti…

Domain Generalization with Small Data

Kecheng Chen, Elena Gal, Hong Yan +1

In this work, we propose to tackle the problem of domain generalization in the context of \textit{insufficient samples}. Instead of extracting latent feature embeddings based on de…
