Improving robustness of softmax corss-entropy loss via inference information

no code implementations1 Jan 2021 Bingbing Song, wei he, Renyang Liu, Shui Yu, Ruxin Wang, Mingming Gong, Tongliang Liu, Wei Zhou

Several state-of-the-arts start from improving the inter-class separability of training samples by modifying loss functions, where we argue that the adversarial samples are ignored and thus limited robustness to adversarial attacks is resulted.

Discriminatively Constrained Semi-supervised Multi-view Nonnegative Matrix Factorization with Graph Regularization

no code implementations26 Oct 2020 Guosheng Cui, Ruxin Wang, Dan Wu, Ye Li

In recent years, semi-supervised multi-view nonnegative matrix factorization (MVNMF) algorithms have achieved promising performances for multi-view clustering.

Smoothness Sensor: Adaptive Smoothness-Transition Graph Convolutions for Attributed Graph Clustering

no code implementations12 Sep 2020 Chaojie Ji, Hongwei Chen, Ruxin Wang, Yunpeng Cai, Hongyan Wu

Clustering the nodes of an attributed graph, in which each node is associated with a set of feature attributes, has attracted significant attention.

Graph Polish: A Novel Graph Generation Paradigm for Molecular Optimization

no code implementations14 Aug 2020 Chaojie Ji, Yijia Zheng, Ruxin Wang, Yunpeng Cai, Hongyan Wu

In this study, we present a novel molecular optimization paradigm, Graph Polish, which changes molecular optimization from the traditional "two-language translating" task into a "single-language polishing" task.

Boundary-aware Context Neural Network for Medical Image Segmentation

no code implementations3 May 2020 Ruxin Wang, Shuyuan Chen, Chaojie Ji, Jianping Fan, Ye Li

In this paper, we formulate a boundary-aware context neural network (BA-Net) for 2D medical image segmentation to capture richer context and preserve fine spatial information.

Digital image splicing detection based on Markov features in QDCT and QWT domain

no code implementations28 Aug 2017 Ruxin Wang, Wei Lu, Shijun Xiang, Xianfeng Zhao, Jinwei Wang

In this paper, a color image splicing detection approach is proposed based on Markov transition probability of quaternion component separation in quaternion discrete cosine transform (QDCT) domain and quaternion wavelet transform (QWT) domain.
