Modeling Heterogeneous Statistical Patterns in High-dimensional Data by Adversarial Distributions: An Unsupervised Generative Framework
Han Zhang, Wenhao Zheng, Charley Chen +4
Since the label collecting is prohibitive and time-consuming, unsupervised methods are preferred in applications such as fraud detection. Meanwhile, such applications usually requi…
Dilated-Scale-Aware Attention ConvNet For Multi-Class Object Counting
Wei Xu, Dingkang Liang, Yixiao Zheng +1
Object counting aims to estimate the number of objects in images. The leading counting approaches focus on the single category counting task and achieve impressive performance. Not…
FAWA: Fast Adversarial Watermark Attack on Optical Character Recognition (OCR) Systems
Lu Chen, Jiao Sun, Wei Xu
Deep neural networks (DNNs) significantly improved the accuracy of optical character recognition (OCR) and inspired many important applications. Unfortunately, OCRs also inherit th…
Beamforming Optimization for IRS-Aided Communications with Transceiver Hardware Impairments
Hong Shen, Wei Xu, Shulei Gong +2
In this paper, we focus on intelligent reflecting surface (IRS) assisted multi-antenna communications with transceiver hardware impairments encountered in practice. In particular,…
Sliding Differential Evolution Scheduling for Federated Learning in Bandwidth-Limited Networks
Yifan Luo, Jindan Xu, Wei Xu +1
Federated learning (FL) in a bandwidth-limited network with energy-limited user equipments (UEs) is under-explored. In this paper, to jointly save energy consumed by the battery-li…
Robots State Estimation and Observability Analysis Based on Statistical Motion Models
Wei Xu, Dongjiao He, Yixi Cai +1
This paper presents a generic motion model to capture mobile robots' dynamic behaviors (translation and rotation). The model is based on statistical models driven by white random p…
