LookinGood^π: Real-time Person-independent Neural Re-rendering for High-quality Human Performance Capture

no code implementations15 Dec 2021 Xiqi Yang, Kewei Yang, Kang Chen, Weidong Zhang, Weiwei Xu

The guidance of the rendered image is realized by blending features from two branches effectively in the training of the detail branch, which improves both the warping accuracy and the details' fidelity.

SPatchGAN: A Statistical Feature Based Discriminator for Unsupervised Image-to-Image Translation

1 code implementation ICCV 2021 Xuning Shao, Weidong Zhang

For unsupervised image-to-image translation, we propose a discriminator architecture which focuses on the statistical features instead of individual patches.

no code implementations29 Dec 2020 Xiu-Shen Wei, Yu-Yan Xu, Yazhou Yao, Jia Wei, Si Xi, Wenyuan Xu, Weidong Zhang, Xiaoxin Lv, Dengpan Fu, Qing Li, Baoying Chen, Haojie Guo, Taolue Xue, Haipeng Jing, Zhiheng Wang, Tianming Zhang, Mingwen Zhang

WebFG 2020 is an international challenge hosted by Nanjing University of Science and Technology, University of Edinburgh, Nanjing University, The University of Adelaide, Waseda University, etc.

Soft policy optimization using dual-track advantage estimator

1 code implementation15 Sep 2020 Yubo Huang, Xuechun Wang, Luobao Zou, Zhiwei Zhuang, Weidong Zhang

In reinforcement learning (RL), we always expect the agent to explore as many states as possible in the initial stage of training and exploit the explored information in the subsequent stage to discover the most returnable trajectory.

SARG: A Novel Semi Autoregressive Generator for Multi-turn Incomplete Utterance Restoration

1 code implementation4 Aug 2020 Mengzuo Huang, Feng Li, Wuhe Zou, Weidong Zhang

Dialogue systems in open domain have achieved great success due to the easily obtained single-turn corpus and the development of deep learning, but the multi-turn scenario is still a challenge because of the frequent coreference and information omission.

The Expressivity and Training of Deep Neural Networks: toward the Edge of Chaos?

no code implementations11 Oct 2019 Gege Zhang, Gangwei Li, Ningwei Shen, Weidong Zhang

In this paper, we provide a quantitative analysis of the expressivity for the deep neural network (DNN) from its dynamic model, where the Hilbert space is employed to analyze the convergence and criticality.

Edge-Semantic Learning Strategy for Layout Estimation in Indoor Environment

no code implementations3 Jan 2019 Weidong Zhang, Wei zhang, Jason Gu

More specifically, we present an encoder-decoder network with shared encoder and two separate decoders, which are composed of multiple deconvolution (transposed convolution) layers, to jointly learn the edge maps and semantic labels of a room image.
