PromptAD: Learning Prompts with only Normal Samples for Few-Shot Anomaly Detection

2 code implementations8 Apr 2024 Xiaofan Li, Zhizhong Zhang, Xin Tan, Chengwei Chen, Yanyun Qu, Yuan Xie, Lizhuang Ma

The vision-language model has brought great improvement to few-shot industrial anomaly detection, which usually needs to design of hundreds of prompts through prompt engineering.

DrivingDiffusion: Layout-Guided multi-view driving scene video generation with latent diffusion model

no code implementations11 Oct 2023 Xiaofan Li, Yifu Zhang, Xiaoqing Ye

To alleviate the problem, we propose a spatial-temporal consistent diffusion framework DrivingDiffusion, to generate realistic multi-view videos controlled by 3D layout.

USL-Net: Uncertainty Self-Learning Network for Unsupervised Skin Lesion Segmentation

no code implementations23 Sep 2023 Xiaofan Li, Bo Peng, Jie Hu, Changyou Ma, DaiPeng Yang, Zhuyang Xie

Rather than risk potential pseudo-labeling errors or learning confusion by forcefully classifying these regions, we consider them as uncertainty regions, exempting them from pseudo-labeling and allowing the network to self-learn.

Over-the-Air Aggregation for Federated Learning: Waveform Superposition and Prototype Validation

no code implementations27 Oct 2021 Huayan Guo, Yifan Zhu, Haoyu Ma, Vincent K. N. Lau, Kaibin Huang, Xiaofan Li, Huabin Nong, Mingyu Zhou

In this paper, we develop an orthogonal-frequency-division-multiplexing (OFDM)-based over-the-air (OTA) aggregation solution for wireless federated learning (FL).

Most Probable Evolution Trajectories in a Genetic Regulatory System Excited by Stable Lévy Noise

no code implementations9 Oct 2018 Xiujun Cheng, Hui Wang, Xiao Wang, Jinqiao Duan, Xiaofan Li

We especially examine those most probable trajectories from low concentration state to high concentration state (i. e., the likely transcription regime) for certain parameters, in order to gain insights into the transcription processes and the tipping time for the transcription likely to occur.
