Transformer-Based Multi-Branch Single Image Deraining Method Postprint

Tan Fuxiang, Qian Yurong, Kong Yuting, Zhang Hao, Zhou Daxin, Fan Yingying, Chen Long
2022-04-07 ChinaXiv: chinaxiv-202204.00073

Rain streaks severely degrade the quality of captured images, affecting subsequent computer vision tasks. To improve the quality of rainy images, we propose a Transformer-based single image deraining algorithm. First, the algorithm obtains a large receptive field through a transformer with a windowi…

Postprint: P4-Based Consistency Verification of SDN Control-Data Plane Flow Rules

Xia Jiqiang, Cui Pengshuai, Li Ziyong, Lan Julong
2022-04-07 ChinaXiv: chinaxiv-202204.00074

To address the problem of inconsistency between control-plane and data-plane flow rules caused by hardware/software failures and misconfigurations in the SDN data plane, we propose a P4-based consistency verification mechanism for SDN control-data plane flow rules (P4CV, P4-based Consistency Verific…

Postprint of IDNC Cooperative Retransmission Scheme Based on Device Heterogeneity and D2D Networks

Yao Yukun, Chen Xinyao, Yang Jie
2022-04-07 ChinaXiv: chinaxiv-202204.00078

To satisfy the personalized requirements of end users and reduce the transmission delay in D2D networks, a cooperative retransmission scheme based on instantly decodable network coding (IDNC) with terminal differentiation is proposed. First, this scheme introduces a novel IDNC algorithmic framework …

Design and Implementation of an FPGA-based 10 Gigabit Ethernet UDP/IP Hardware Protocol Stack Postprint

Dong Yongji, Wang Yu, Yuan Zheng
2022-04-07 ChinaXiv: chinaxiv-202204.00081

To address the inability of traditional software-based protocol stacks to meet the demands of high-speed data transmission and processing, a hardware-accelerated UDP protocol stack design scheme is proposed. Based on the highly efficient parallel characteristics of hardware, this scheme implements a…

Multi-Objective Optimization for Vehicle Following Based on Joint Lateral and Longitudinal Control: Postprint

Li Mengfan, Qin Wenhu, Cloud China
2022-04-07 ChinaXiv: chinaxiv-202204.00083

To address issues such as poor car-following stability, ineffective tracking, or unsafe conditions caused by significant speed fluctuations of vehicles in congested environments, a multi-objective optimization car-following scheme based on vehicle models and deep reinforcement learning is proposed. …

Postprint of Clothing Compatibility Prediction Model Based on Hypergraph Representation

Li Jian, Li Zhuo, Ma Tianxiang, Liang Jifeng
2022-04-07 ChinaXiv: chinaxiv-202204.00085

To address the limitation that existing clothing compatibility models predominantly focus on exploring compatibility between paired items, we propose a clothing compatibility prediction model based on hypergraph representation. The model first constructs a clothing hypergraph based on the different …

RA-GCN: Mitigating the Over-smoothing Phenomenon in Text Classification (Postprint)

Fanjun Su, Ma Mingxu, Tong Guoxiang
2022-04-07 ChinaXiv: chinaxiv-202204.00086

Most existing algorithms utilizing Graph Neural Networks for text classification have overlooked the over-smoothing problem inherent in GNNs and the discrepancies arising from text graph topological differences, leading to suboptimal performance in text classification. To address this issue, we prop…

A Creativity Survey of Distributed Database System
