Medical Image Segmentation via Single-Source Domain Generalization with Random Amplitude Spectrum Synthesis

1 code implementation7 Sep 2024 Qiang Qiao, Wenyu Wang, Meixia Qu, Kun Su, Bin Jiang, Qiang Guo

The proposed Random Amplitude Spectrum Synthesis for Single-Source Domain Generalization (RAS^4DG) is validated on 3D fetal brain images and 2D fundus photography, and achieves an improved DG segmentation performance compared to other SSDG models.

Breaking the Curse of Quality Saturation with User-Centric Ranking

no code implementations24 May 2023 Zhuokai Zhao, Yang Yang, Wenyu Wang, Chihuang Liu, Yu Shi, Wenjie Hu, Haotian Zhang, Shuang Yang

A key puzzle in search, ads, and recommendation is that the ranking model can only utilize a small portion of the vastly available user interaction data.

Ignorance Is Bliss: The Screening Effect of (Noisy) Information

no code implementations22 Feb 2023 Felix Zhiyu Feng, Wenyu Wang, Yufeng Wu, Gaoqing Zhang

This paper studies the value of a firm's internal information when the firm faces an adverse selection problem arising from unobservable managerial abilities.

Learning to Dub Movies via Hierarchical Prosody Models

1 code implementation CVPR 2023 Gaoxiang Cong, Liang Li, Yuankai Qi, ZhengJun Zha, Qi Wu, Wenyu Wang, Bin Jiang, Ming-Hsuan Yang, Qingming Huang

Given a piece of text, a video clip and a reference audio, the movie dubbing (also known as visual voice clone V2C) task aims to generate speeches that match the speaker's emotion presented in the video using the desired speaker voice as reference.

LS-GAN: Iterative Language-based Image Manipulation via Long and Short Term Consistency Reasoning

2 code implementations journal 2022 Gaoxiang Cong, Liang Li, Zhenhuan Liu, Yunbin Tu, Weijun Qin, Shenyuan Zhang, Chengang Yan, Wenyu Wang, Bin Jiang

To address this issue, we propose a novel Long and Short term consistency reasoning Generative Adversarial Network (LS-GAN), which enhances the awareness of previous objects with current instruction and better maintains the consistency with the user's intent under the continuous iterations.

In this paper, we develop a physics-informed graphical learning algorithm to estimate network parameters of three-phase power distribution systems.

Testing Untestable Neural Machine Translation: An Industrial Case

no code implementations6 Jul 2018 Wujie Zheng, Wenyu Wang, Dian Liu, Changrong Zhang, Qinsong Zeng, Yuetang Deng, Wei Yang, Pinjia He, Tao Xie

To fill the gap of lacking test oracle for in-vivo testing of an NMT system, in this paper, we propose a new approach for automatically identifying translation failures, without requiring reference translations for a translation task; our approach can directly serve as a test oracle for in-vivo testing.
