Adversarial Recurrent Time Series Imputation
Shuo, Yang; Dong, Minjing; Wang, Yunhe; Xu, ChangPublished 2020For the real-world time series analysis, data missing is a ubiquitously existing problem due to anomalies during data collecting and storage. If not treated properly, this problem will seriously hinder the classification, ...Open AccessArticle -
Iterative Privileged Learning
Li, Xue; Du, Bo; Zhang, Yipeng; Xu, Chang; Tao, DachengPublished 2020While in the learning using privileged information paradigm, privileged information may not be as informative as example features in the context of making accurate label predictions, it may be able to provide some effective ...Open AccessArticle -
Long-Term Video Prediction via Criticization and Retrospection
Chen, Xinyuan; Xu, Chang; Yang, Xiaokang; Tao, DachengPublished 2020Video prediction refers to predicting and generating future video frames given a set of consecutive frames. Conventional video prediction methods usually criticize the discrepancy between the ground-truth and predictions ...Open AccessArticle -
Multi-task Learning for Blind Source Separation
Du, Bo; Wang, Shaodong; Xu, Chang; Wang, Nan; Zhang, Liangpei; Tao, DachengPublished 2018Blind source separation (BSS) aims to discover the underlying source signals from a set of linear mixture signals without any prior information of the mixing system, which is a fundamental problem in signal and image ...Open AccessArticle -
Packing Convolutional Neural Networks in the Frequency Domain
Wang, Yunhe; Xu, Chang; Xu, Chao; Tao, DachengPublished 2019Deep convolutional neural networks (CNNs) are successfully used in a number of applications. However, their storage and computational requirements have largely prevented their widespread use on mobile devices. Here we ...Open AccessArticle -
Robust learning with imperfect privileged information
Li, Xue; Du, Bo; Xu, Chang; Zhang, Yipeng; Zhang, Lefei; Tao, DachengPublished 2020In the learning using privileged information (LUPI) paradigm, example data cannot always be clean, while the gathered privileged information can be imperfect in practice. Here, imperfect privileged information can refer ...Open AccessArticle -
ROMIR: Robust Multi-view Image Re-ranking
Li, Jun; Xu, Chang; Yang, Wankou; Sun, Changyin; Kotagiri, Ramamohanarao; Tao, DachengPublished 2019Recently, multi-view features have significantly pro- moted the performance of image re-ranking by providing complementary image descriptions. Without loss of generality, in multi-view re-ranking, multiple heterogeneous ...Open AccessArticle -
Self-supervised Pose Adaptation for Cross-Domain Image Animation
Wang, Chaoyue; Xu, Chang; Tao, DachengPublished 2020Image animation is to animate a still image of the object of interest using poses extracted from another video sequence. Through training on a large-scale video dataset, most existing approaches aim to explore disentangled ...Open AccessArticle
