Analysis of evolutionary algorithms to improve software defect prediction 分析改进软件缺陷预测的进化算法
R. Malhotra, Anshul Khurana
Defect prediction of software is necessary to determine defective parts of software. Defect prediction models are elaborated with the help of software metrics when combined with defective data to predict the classes that are defective. In this paper we have used datasets that statistically resolve the relationship among software metrics and defect vulnerability. The main intent of this paper are 1) Feature selection for defect prediction using proposed evolutionary algorithm 2) Comparing machine learning techniques 3) Use of precision and recall as performance measure for defect prediction 4) 10- fold validation is performed on every model. In this discourse, we predict defective class using 5 machine learning techniques and 2 evolutionary techniques for feature selection. In this work, we have applied evolutionary algorithms for feature selection suitable for each of the classification techniques applied on five open source android packages. Finally, for validation of calculated results, 10-fold validation is used. The results show that using evolutionary algorithms for feature selection can improve precision and recall for RF, DT and SVM. Precision and recall have best rise using SVM model. The use of evolutionary algorithms don't effect precision and recall for statistical classifier. The results obtained from evaluation thus confirm about the prediction of default classes using evolutionary algorithms is better than using only machine learning techniques. The analyzed and calculated results gave us the view about the usage of evolutionary algorithm with statistical classifier is of no use.
软件缺陷预测是确定软件缺陷部分的必要条件。当与有缺陷的数据相结合时,缺陷预测模型在软件度量的帮助下被详细阐述,以预测有缺陷的类。在本文中,我们使用数据集来统计地解决软件度量和缺陷脆弱性之间的关系。本文的主要目的是:1)使用提出的进化算法进行缺陷预测的特征选择;2)比较机器学习技术;3)使用精度和召回率作为缺陷预测的性能度量;4)对每个模型进行10倍验证。在本文中,我们使用5种机器学习技术和2种进化技术进行特征选择来预测缺陷类。在这项工作中,我们应用进化算法进行特征选择,适用于五个开源android软件包上应用的每种分类技术。最后,对计算结果进行10倍验证。结果表明,使用进化算法进行特征选择可以提高RF、DT和SVM的查全率和查全率。支持向量机模型的准确率和召回率均有较好的提高。进化算法的使用不影响统计分类器的准确率和召回率。因此,从评估中获得的结果证实了使用进化算法预测默认类比仅使用机器学习技术更好。分析和计算的结果使我们认识到使用统计分类器的进化算法是无用的。

Identification & enhancement of different skin lesion images by segmentation techniques 基于分割技术的不同皮肤病变图像识别与增强
Neetu Mittal, Sudhir Tanwar, S. Khatri
A skin lesion is a portion of skin with an abnormal growth or presence due to a skin disease. Skin diseases at their early stages can be cured very easily; otherwise they begin to spread to other parts of the body and may be deadly. An early detection of skin disease is essential for such patients. Due to the high cost involved in various dermatology testing procedures for every patient, an automated system is required to give better lesion images and vision to help the doctors to further diagnose and prescribe the correct prescription and medication. In this paper, an innovative approach for automatic identification of skin lesions is proposed. To improve the quality of skin lesion images, Median filtering and Sobel edge detection techniques have been implemented for filtering and segmentation. The efficacy of the proposed work has been verified by measuring the entropy of the resultant images obtained for different skin diseases. The performance is tested on a dataset of 70 samples from 150 medical images of different body parts with 10 different classes of skin diseases.
皮肤病变是皮肤的一部分,由于皮肤疾病而出现异常生长或存在。早期的皮肤病很容易治愈;否则,它们开始扩散到身体的其他部位,可能是致命的。对这类患者来说,早期发现皮肤病至关重要。由于每位患者的各种皮肤科检查程序成本高昂,因此需要一个自动化系统来提供更好的病变图像和视力,以帮助医生进一步诊断并开出正确的处方和药物。本文提出了一种新颖的皮肤损伤自动识别方法。为了提高皮肤病变图像的质量,采用中值滤波和Sobel边缘检测技术对图像进行滤波和分割。通过测量不同皮肤疾病所获得的图像的熵,验证了所提出工作的有效性。该性能在70个样本的数据集上进行了测试,这些样本来自150个不同身体部位的医学图像,包含10种不同类型的皮肤病。

Research on channel estimation algorithm of MIMO relay system based on PARAFAC model 基于PARAFAC模型的MIMO中继系统信道估计算法研究
Kuiyuan Zhang, Jianping Li, E. J. Guo
For the semi-blind estimation problem of two-hop multi-input multi-output amplified forwarding (MIMO-AF) relay system, the parallel factor (PARAFAC) model is constructed for the received signal. Using the uniqueness of its decomposition, an ALS-LS algorithm is proposed. Based on the algorithm of least squares alternating (ALS) and adding relaxation factor, the ALS algorithm is used to achieve certain convergence conditions. The estimation result of the former algorithm is taken as the initial value, and then based on the ALS algorithm adding relaxation factor, using the relaxation factor to change the gradient direction, so as to speed up the convergence rate. And the performance of the channel model is analyzed by different parameters of the channel model. Simulation results show: compared with the existing least squares alternate algorithm, the complexity and iteration times of the algorithm are reduced, and the convergence speed of the algorithm is accelerated.

Relative performance of multipliers: A fault tolerance perspective for parallel FFTs 乘法器的相对性能:并行fft的容错角度
Sai Satish Inala, P. Pushpalatha
As technology will increase as quality of circuits additionally will increase that tends face reliableness challenges and creates want for fault-tolerant implementations. Signal processing and communication circuits are effected by soft errors. The complexity increases as protection against soft errors increases in many applications. There are distinct advancements in VLSI technology i.e., number of circuits called Fast Fourier Transforms (FFTs) increased on a small chip. In this case we have to implement the fault tolerance in order to preserve the data efficiently. There are distinct techniques exist to achieve fault tolerance. The most used technique is algorithmic-primarily based fault tolerance (ABFT) techniques that attempt to use recursive properties to find and accurate errors. But in advanced systems it is not unusual that variety of the filters function in parallel, as an instance a filters having same response are connected in parallel and subjected to different inputs. ECC (error correction codes) is the one of the method to detect and correct errors in FFTs. We propose different multipliers in FFTs architecture for which multiplier is most suitable in whole design. In this proposed method each filter can be considered as a bit. This method allows most efficient protection when there is large number of parallel filters present. The method is evaluated employing a Array, changed booth, Wallace tree and Dadda multipliers showing the potency in terms of speed, low power consumption and space.
随着技术的发展和电路质量的提高,往往会面临可靠性方面的挑战,并产生对容错实现的需求。信号处理和通信电路受到软误差的影响。在许多应用程序中,随着对软错误保护的增加,复杂性也随之增加。VLSI技术有明显的进步,即在小芯片上增加了称为快速傅里叶变换(fft)的电路数量。在这种情况下,为了有效地保存数据,我们必须实现容错。有不同的技术可以实现容错。最常用的技术是基于算法的容错(ABFT)技术,它尝试使用递归属性来查找和精确错误。但在先进的系统中,各种滤波器并联工作并不罕见,例如,具有相同响应的滤波器并联连接并受到不同的输入。纠错码(ECC)是fft中检测和纠错的一种方法。我们在fft架构中提出了不同的乘法器,其中乘法器在整个设计中是最合适的。在该方法中,每个滤波器都可以看作是一个比特。当存在大量并联滤波器时,这种方法允许最有效的保护。该方法采用阵列、改变摊位、华莱士树和Dadda乘数器进行评估,显示出在速度、低功耗和空间方面的潜力。

The method is evaluated employing a Array, changed booth, Wallace tree and Dadda multipliers showing the potency in terms of speed, low power consumption and space.","PeriodicalId":357118,"journal":{"name":"2017 6th International Conference on Reliability, Infocom Technologies and Optimization (Trends and Future Directions) (ICRITO)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115224264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anti social comment classification based on kNN algorithm 基于kNN算法的反社会评论分类
Nidhi Chandra, S. Khatri, S. Som
Billions of contributions are made every day across multiple online communities and social media websites in the form of social messages, social blogs and online discussion. The aim of this paper is to identify such comments and posts which are racist and malicious in nature so that they could be effetely banned and removed in order to counter them. This article uses set of documents with racist comments as text corpus on which appropriate machine learning algorithm is applied to detect racist comments or meaning. To detect anti-social content there is a need to find the extent of similarity between a pair of text messages as a source and classified terms which are antisocial or in discriminating terms. The approach devised in this article to detect antisocial behavior is a technique based on term frequency based content classification.
每天在多个在线社区和社交媒体网站上,以社交信息、社交博客和在线讨论的形式做出数十亿的贡献。本文的目的是确定这些评论和帖子是种族主义和恶意的性质,以便他们可以有效地禁止和删除,以对抗他们。本文使用一组带有种族主义评论的文档作为文本语料库,并在其上应用适当的机器学习算法来检测种族主义评论或含义。为了检测反社会内容,需要找到作为来源的一对短信与反社会或歧视性术语的分类术语之间的相似性程度。本文设计的检测反社会行为的方法是一种基于词频的内容分类技术。
