With the continuous expansion of software applications,people’s requirements for software quality are increasing.Software defect prediction is an important technology to improve software quality.It often encodes the software into several features and applies the machine learning method to build defect prediction classifiers,which can estimate the software areas is clean or buggy.However,the current encoding methods are mainly based on the traditional manual features or the AST of source code.Traditional manual features are difficult to reflect the deep semantics of programs,and there is a lot of noise information in AST,which affects the expression of semantic features.To overcome the above deficiencies,we combined with the Convolutional Neural Networks(CNN)and proposed a novel compiler Intermediate Representation(IR)based program encoding method for software defect prediction(CIR-CNN).Specifically,our program encoding method is based on the compiler IR,which can eliminate a large amount of noise information in the syntax structure of the source code and facilitate the acquisition of more accurate semantic information.Secondly,with the help of data flow analysis,a Data Dependency Graph(DDG)is constructed on the compiler IR,which helps to capture the deeper semantic information of the program.Finally,we use the widely used CNN model to build a software defect prediction model,which can increase the adaptive ability of the method.To evaluate the performance of the CIR-CNN,we use seven projects from PROMISE datasets to set up comparative experiments.The experiments results show that,in WPDP,with our CIR-CNN method,the prediction accuracy was improved by 12%for the AST-encoded CNN-based model and by 20.9%for the traditional features-based LR model,respectively.And in CPDP,the AST-encoded DBNbased model was improved by 9.1%and the traditional features-based TCA+model by 19.2%,respectively.

Crosstalk Aware Register Reallocation Method for Green Compilation

Computers, Materials & Continua 2020年第6期63卷 1357-1371页

作者： Sheng Xiao Jing Selena He Xi Yang Yazhe Wang Lu Jin Information Science and Engineering Department Hunan First Normal UniversityChangsha410205China Computer School Wuhan UniversityWuhan430072China Department of Computer Science Kennesaw State UniversityKennesaw30144-5588USA Hunan Guangyi Experimental Middle School Changsha410205China

As nanoscale processing becomes the mainstream in IC manufacturing,the crosstalk problem rises as a serious challenge,not only for energy-efficiency and performance but also for security requirements.In this paper,we propose a register reallocation algorithm called Nearby Access based Register Reallocation(NARR)to reduce the crosstalk between instruction buses.The method includes construction of the software Nearby Access Aware Interference Graph(NAIG),using data flow analysis at assembly level,and reallocation of the registers to the software.Experimental results show that the crosstalk could be dramatically minimized,especially for 4C crosstalk,with a reduction of 80.84%in average,and up to 99.99%at most.

Spreading Social Influence with both Positive and Negative Opinions in Online Networks

引用

Big Data Mining and Analytics 2019年第2期2卷 100-117页

作者： jing (selena) he Meng Han Shouling Ji Tianyu Du Zhao Li College of Computing and Software Engineering at Kennesaw State University Department of Computer Science at Zhejiang University Alibaba Group

Social networks are important media for spreading information, ideas, and influence among individuals.Most existing research focuses on understanding the characteristics of social networks, investigating how information is spread through the "word-of-mouth" effect of social networks, or exploring social influences among individuals and groups. However, most studies ignore negative influences among individuals and groups. Motivated by the goal of alleviating social problems, such as drinking, smoking, and gambling, and influence-spreading problems, such as promoting new products, we consider positive and negative influences, and propose a new optimization problem called the Minimum-sized Positive Influential Node Set(MPINS) selection problem to identify the minimum set of influential nodes such that every node in the network can be positively influenced by these selected nodes with no less than a threshold of ?. Our contributions are threefold. First, we prove that, under the independent cascade model considering positive and negative influences, MPINS is APX-hard. Subsequently, we present a greedy approximation algorithm to address the MPINS selection problem. Finally, to validate the proposed greedy algorithm, we conduct extensive simulations and experiments on random graphs and seven different realworld data sets that represent small-, medium-, and large-scale networks.

本科学位课程已逐渐发展到包括研究类项目在本科生的毕业设计课程里,同时企业越来越需要具有先进技术和研究技能的毕业生。文章详细介绍了一个由2位导师、4位本科生和1位研究生组成的团队,在肯尼索州立大学(KSU)最后一年的毕业设计课程中,设计和实现一个基于物联网(Io T)的概念证明的研究项目的成功经验。物联网涉及连接物理对象或现象到互联网,这提供了利用射频识别(RFID)、近场通信(NFC)、无线传感器网络(WSN)和通用移动访问的先进技术来构建智能化的系统和应用的机会。在这个案例中,办公室/实验室椅子要被连接到互联网。具体而言,一个组装的Arduino系统负责自动扫描用户的ID且获取座椅的占用状态,然后把这些信息发送到云服务器。在云中收集和分析的数据可以在Android的应用程序中显示。该物联网案例的成功就是一个很好的例子,学生在研究过程中学习先进的技术,以跟上计算机科学快速变化的步伐。

A Cross Language Code Security Audit Framework Based on Normalized Representation

引用

Journal of Quantum Computing 2022年第2期4卷 75-84页

作者： Yong Chen Chao Xu Jing Selena He Sheng Xiao School of Information Engineering Nanjing Audit UniversityNanjing211815China Department of Computer Science Kennesaw State UniversityKennesaw30144-5588USA Information Science and Engineering Department Hunan First Normal UniversityChangsha410205China

With the rapid development of information technology,audit objects and audit itself are more and more inseparable from software.As an important means of software security audit,code security audit will become an important aspect of future audit that cannot be ignored.However,the existing code security audit ismainly based on source code,which is difficult to meet the audit needs of more and more programming languages and binary commercial software.Based on the idea of normalized transformation,this paper constructs a cross language code security audit framework(CLCSA).CLCSA first uses compile/decompile technology to convert different highlevel programming languages and binary codes into normalized representation,and then usesmachine learning technology to build a cross language code security audit model based on normalized representation to evaluate code security and find out possible code security vulnerabilities.Finally,for the discovered vulnerabilities,the heuristic search strategy will be used to find the best repair scheme from the existing normalized representation sample library for automatic repair,which can improve the effectiveness of code security audit.CLCSA realizes the normalized code security audit of different types and levels of code,which provides a strong support for improving the breadth and depth of code security audit.

Plant pests and diseases threaten food security by causing over 10%loss of global crops yield.Plant immunity relies on a complex hormonal signaling network in which jasmonates(JAs)play a central role.JAs are fatty acid–derived hormones ubiquitous in the plant kingdom similar to animal prostaglandins,and are essential phytohormones regulating development,environmental adaptation and defense against necrotrophic pathogens and insects in plants.
