In-Order Chart-Based Constituent Parsing

no code implementations8 Feb 2021 Yang Wei, Yuanbin Wu, Man Lan

We propose a novel in-order chart-based model for constituent parsing.

SRQA: Synthetic Reader for Factoid Question Answering

1 code implementation2 Sep 2020 Jiuniu Wang, Wenjia Xu, Xingyu Fu, Yang Wei, Li Jin, Ziyan Chen, Guangluan Xu, Yirong Wu

This model enhances the question answering system in the multi-document scenario from three aspects: model structure, optimization goal, and training method, corresponding to Multilayer Attention (MA), Cross Evidence (CE), and Adversarial Training (AT) respectively.

A Span-based Linearization for Constituent Trees

1 code implementation ACL 2020 Yang Wei, Yuanbin Wu, Man Lan

We propose a novel linearization of a constituent tree, together with a new locally normalized model.

RRU-Net: The Ringed Residual U-Net for Image Splicing Forgery Detection

1 code implementation cvpr 2019 workshop 2019 Xiuli Bi, Yang Wei, Bin Xiao, Weisheng Li

The core idea of the RRU-Net is to strengthen the learning way of CNN, which is inspired by the recall and the consolidation mechanism of the human brain and implemented by the propagation and the feedback process of the residual in CNN.

TightCap: 3D Human Shape Capture with Clothing Tightness Field

1 code implementation4 Apr 2019 Xin Chen, Anqi Pang, Yang Wei, Lan Xui, Jingyi Yu

In this paper, we present TightCap, a data-driven scheme to capture both the human shape and dressed garments accurately with only a single 3D human scan, which enables numerous applications such as virtual try-on, biometrics and body evaluation.

Virtual Try-on

Adversarial Metric Learning

no code implementations9 Feb 2018 Shuo Chen, Chen Gong, Jian Yang, Xiang Li, Yang Wei, Jun Li

In distinguishment stage, a metric is exhaustively learned to try its best to distinguish both the adversarial pairs and the original training pairs.
