Kavli Affiliate: Zheng Zhu | First 5 Authors: Yiwei Chen, Yan Huang, Qingxin Li, Bingbing Tong, Guangli Kuang | Summary: The fractional quantum Hall (FQH) states are exotic quantum many-body phases whose elementary charged excitations are neither bosons nor fermions but anyons, obeying fractional braiding statistics. While most FQH states are believed to have Abelian […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yunqi Gu, Tao Zhou, Yizhe Zhang, Yi Zhou, Kelei He | Summary: Automatic polyp segmentation plays a crucial role in the early diagnosis and treatment of colorectal cancer (CRC). However, existing methods heavily rely on fully supervised training, which requires a large amount of labeled data with […]

However, existing methods heavily rely on fully supervised training, which requires a large amount of labeled data with time-consuming pixel-wise annotations. Moreover, accurately segmenting lesions […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Bingzhi Liu, Yin Cao, Haohe Liu, Yi Zhou, | Summary: Diffusion models have demonstrated promising results in text-to-audio generation tasks. However, their practical usability is hindered by slow sampling speeds, limiting their applicability in high-throughput scenarios. To address this challenge, progressive distillation methods have been effective in […]
