EvoSCM: Scientific Belief Revision Through Causal Model Evolution and Experimentation

Qing Zhao, Haowei Li, Weijian Deng +3

Scientific discovery depends on the ability to form hypotheses, test them through experiments, and revise them when evidence disagrees. Existing LLM agents support this process by…

Ground4D: Consistency-Aware 4D Reconstruction from Monocular Video

Qing Zhao, Weijian Deng, Pengxu Wei +1

Learning a 4D scene representation from a single monocular video that supports dynamic novel-view synthesis while maintaining faithful geometry over time remains challenging. Dynam…

Unveiling Perceptual Artifacts: A Fine-Grained Benchmark for Interpretable AI-Generated Image Detection

Yao Xiao, Weiyan Chen, Jiahao Chen +8

Current AI-Generated Image (AIGI) detection approaches predominantly rely on binary classification to distinguish real from synthetic images, often lacking interpretable or convinc…

Delving into Cascaded Instability: A Lipschitz Continuity View on Image Restoration and Object Detection Synergy

Qing Zhao, Weijian Deng, Pengxu Wei +4

To improve detection robustness in adverse conditions (e.g., haze and low light), image restoration is commonly applied as a pre-processing step to enhance image quality for the de…

Thinking Before You Speak: A Proactive Test-time Scaling Approach

Cong Liu, Wenchang Chai, Hejun Wu +3

Large Language Models (LLMs) often exhibit deficiencies with complex reasoning tasks, such as maths, which we attribute to the discrepancy between human reasoning patterns and thos…

Can We Achieve Efficient Diffusion without Self-Attention? Distilling Self-Attention into Convolutions

ZiYi Dong, Chengxing Zhou, Weijian Deng +3

Contemporary diffusion models built upon U-Net or Diffusion Transformer (DiT) architectures have revolutionized image generation through transformer-based attention mechanisms. The…

Towards Understanding the Robustness of Diffusion-Based Purification: A Stochastic Perspective

Yiming Liu, Kezhao Liu, Yao Xiao +4

Diffusion-Based Purification (DBP) has emerged as an effective defense mechanism against adversarial attacks. The success of DBP is often attributed to the forward diffusion proces…

Towards Real-World Burst Image Super-Resolution: Benchmark and Method

Pengxu Wei, Yujing Sun, Xingbei Guo +4

Despite substantial advances, single-image super-resolution (SISR) is always in a dilemma to reconstruct high-quality images with limited information from one input image, especial…
