A review of early detection of cancers using breath analysis 呼吸分析在癌症早期检测中的应用综述
D. Arul, Pon Daniel, K. Thangavel, R. Subash, C. Boss
Authentic and accurate information is basic to any disease control initiative. More than 70% of diseases are related to life-style factors such as food and beverage practices, personal habits, infections, tobacco consumption and social customs. In addition, urbanization, industrialization and increasing life-span are also known to influence the cancer pattern globally. This necessitates proper appreciation of risk factors and other causes of cancer by the people. Various modalities for early detection through screening are being investigated. Majority of the patients have locally advanced or disseminated disease at presentation and are not candidates for surgery. Chemotherapy applied as an adjunct with radiation improves survival and the quality of life. New anticancer drugs, which have emerged during the last decade, have shown an improved efficacy toxicity ratio. This review is more about the diagnosing cancer at an early stage using invasive electronic sensors and intelligent computing methods by capturing only the breath of the human being. Strengthening the methods for early diagnosis of cancers and improved treatments will have a significant impact on cutting death rates.
真实和准确的信息是任何疾病控制行动的基础。70%以上的疾病与生活方式因素有关,如饮食习惯、个人习惯、感染、烟草消费和社会习俗。此外,已知城市化、工业化和寿命延长也会影响全球癌症格局。这就需要人们正确认识癌症的危险因素和其他原因。正在研究通过筛查进行早期发现的各种方式。大多数患者在发病时已局部进展或弥散性疾病,不适合手术。化疗作为放疗的辅助手段可以提高生存率和生活质量。新的抗癌药物,在过去的十年中出现,已经显示出改善的疗效和毒性比。本文综述了利用侵入性电子传感器和智能计算方法,通过捕捉人类的呼吸,在早期诊断癌症。加强癌症早期诊断方法和改进治疗方法将对降低死亡率产生重大影响。

Unsupervised hybrid PSO — Relative reduct approach for feature reduction 特征约简的无监督混合粒子群-相对约简方法
H. Inbarani, P. K. Nizar Banu
Feature reduction selects more informative features and reduces the dimensionality of a database by removing the irrelevant features. Selecting features in unsupervised learning scenarios is a harder problem than supervised feature selection due to the absence of class labels that would guide the search for relevant features. Rough set is proved to be efficient tool for feature reduction and needs no additional information. PSO (Particle Swarm Optimization) is an evolutionary computation technique which finds global optimum solution in many applications. This work combines the benefits of both PSO and rough sets for better data reduction. This paper describes a novel Unsupervised PSO based Relative Reduct (US-PSO-RR) for feature selection which employs a population of particles existing within a multi-dimensional space and dependency measure. The performance of the proposed algorithm is compared with the existing unsupervised feature selection methods USQR (UnSupervised Quick Reduct) and USSR (UnSupervised Relative Reduct) and the effectiveness of the proposed approach is measured by using Clustering evaluation indices.
特征约简选择更多的信息特征,并通过删除不相关的特征来降低数据库的维数。在无监督学习场景中选择特征是一个比有监督特征选择更难的问题,因为缺乏指导搜索相关特征的类标签。粗糙集被证明是一种有效的特征约简工具,不需要额外的信息。粒子群算法(PSO)是一种寻找全局最优解的进化计算方法,在许多应用中得到广泛应用。这项工作结合了粒子群算法和粗糙集的优点,以更好地减少数据。本文描述了一种新的基于无监督粒子群的相对约简(US-PSO-RR)特征选择方法,该方法利用存在于多维空间中的粒子群和依赖度量。将所提算法的性能与现有的无监督特征选择方法USQR (unsupervised Quick约简)和USSR (unsupervised Relative约简)进行了比较,并使用聚类评价指标来衡量所提方法的有效性。

K. Kuppusamy, K. Thamodaran
An encryption scheme provides security against illegal duplication and manipulation of multimedia contents especially to digital images. In this paper a novel optimized partial image encryption scheme based on Particle swarm optimization and the Daubechies4 transform is developed which provide solutions to the issues such as statistical attacks and confidentiality. The selected coefficients are encrypted in Daubechies4 domain with help of particle swarm optimization(PSO). The IQIM is used to measure the image quality distortion based on three factors such as loss of correlation, luminance distortion, and contrast distortion. The experimental results are presented to demonstrate the effectiveness of the proposed scheme.

Rule extraction from neural networks — A comparative study 神经网络规则提取的比较研究
Gethsiyal Augasta M, T. Kathirvalavakumar
Though neural networks have achieved highest classification accuracy for many classification problems, the obtained results may not be interpretable as they are often considered as black box. To overcome this drawback researchers have developed many rule extraction algorithms. This paper has discussed on various rule extraction algorithms based on three different rule extraction approaches namely decompositional, pedagogical and eclectic. Also it evaluates the performance of those approaches by comparing different algorithms with these three approaches on three real datasets namely Wisconsin breast cancer, Pima Indian diabetes and Iris plants.
尽管神经网络在许多分类问题上取得了最高的分类精度,但由于神经网络通常被认为是黑盒子,因此得到的结果可能无法解释。为了克服这一缺点,研究人员开发了许多规则提取算法。本文讨论了基于分解、教学和折衷三种不同的规则提取方法的各种规则提取算法。此外,它还通过比较这三种方法在三个真实数据集上的不同算法来评估这些方法的性能,这些数据集分别是威斯康星州乳腺癌、皮马印第安人糖尿病和鸢尾植物。

Cubical key generation and encryption algorithm based on hybrid cube's rotation 基于混合立方体旋转的立方体密钥生成与加密算法
D. Rajavel, S. Shantharajah
We propose a new cryptographic algorithm based on combination of hybridization and rotation of cubes. Hybridization was performed using magic cubes with m number of n order magic square for the generating hybrid cubes. The obtained hybrid cube was shuffled via rotation square, which in turn generated from randomly selected magic square. Cubic rotation was performed as same that of simple Rubik's cube shuffling. In general, two phase of rotation was carried out, in which first one involves in the rotation of hybrid cube to generate a key and the second one involves in the rotation of original text to give rise a cipher text. The generated key was in cubical form and cipher text generated from this encryption algorithm is more secure from cryptanalysis.
提出了一种新的基于立方体杂化和旋转相结合的密码算法。对生成的杂交立方体采用m个n阶魔方的魔方进行杂交。通过旋转方块对得到的混合立方体进行洗牌,旋转方块由随机选择的魔方生成。立方体旋转与简单的魔方洗牌相同。一般情况下,旋转过程分为两个阶段,第一个阶段是旋转混合立方体生成密钥,第二个阶段是旋转原始文本生成密文。生成的密钥为立方形式,该加密算法生成的密文具有较强的密码分析安全性。

Enhancing the performance of MANET using EESCP 利用EESCP提高MANET的性能
G. Kumar, M. Kaliappan, L. J. Julus
Recent year a rapid development and widespread application of mobile ad hoc networks suffer from security attacks and privacy issues which dramatically impede their applications. To cope with the attacks, a large variety of intrusion detection techniques such as authentication, authorization, cryptographic protocols and key management schemes have been developed. Clustering methods allow fast connection, better routing and topology management of mobile ad hoc networks (MANET). This paper, we have introduced new mechanism called Energy Efficiency and Secure Communication Protocol (EESCP) is to divide the MANET into a set of 2-hop clusters where each node belongs to at least one cluster. The nodes in each cluster elect a leader node (cluster head) to serve as the IDS for the entire cluster. To balance the resource consumption weight based leader election model is used, which elected an optimal collection of leaders to minimize the overall resource consumption and obtaining secure communication using diffie-Hellman key exchange protocol.
近年来,移动自组织网络得到了迅速发展和广泛应用,但安全攻击和隐私问题严重阻碍了其应用。为了应对这些攻击,人们开发了各种入侵检测技术,如身份验证、授权、加密协议和密钥管理方案。聚类方法允许快速连接,更好的路由和拓扑管理的移动自组织网络(MANET)。在本文中,我们引入了一种新的机制,称为能源效率和安全通信协议(EESCP),该机制将MANET划分为一组2跳集群,其中每个节点至少属于一个集群。每个集群中的节点选举一个领导节点(集群头)作为整个集群的IDS。为了平衡资源消耗,采用基于权重的领导者选举模型,选择最优的领导者集合,使整体资源消耗最小,并使用diffie-Hellman密钥交换协议获得安全通信。

Computational time factor analysis of K-means algorithm on actual and transformed data clustering K-means算法在实际和转换后的数据聚类中的计算时间因子分析
D. A. Kumar, M. Annie, T. Begum
Clustering is the process of partitioning a set of objects into a distinct number of groups or clusters, such that objects from the same group are more similar than objects from different groups. Clusters are the simple and compact representation of a data set and are useful in applications, where we have no prior knowledge about the data set. There are many approaches to data clustering that vary in their complexity and effectiveness due to its wide number of applications. K-means is a standard and landmark algorithm for clustering data. This multi-pass algorithm has higher time complexity. But in real time we want the algorithm which is time efficient. Hence, here we are giving a new approach using wiener transformation. Here the data is wiener transformed for k-means clustering. The computational results shows that the proposed approach is highly time efficient and also it finds very fine clusters.
聚类是将一组对象划分为不同数量的组或集群的过程,这样来自同一组的对象比来自不同组的对象更相似。聚类是数据集的简单而紧凑的表示,在我们对数据集没有先验知识的应用程序中非常有用。有许多数据聚类方法,由于其广泛的应用程序,它们的复杂性和有效性各不相同。K-means是一种标准的、具有里程碑意义的数据聚类算法。这种多通道算法具有较高的时间复杂度。但在实时情况下,我们需要的是时间效率高的算法。因此,这里我们给出了一种使用维纳变换的新方法。这里的数据是k均值聚类的维纳变换。计算结果表明,该方法具有很高的时间效率,并且能够找到非常精细的聚类。

M. Sumathi, R. Barani
Image fusion is the process of combining information from two or more images of a same scene into a single composite image that is more informative and is more suitable for visual perception or computer processing. The main objective of this paper is to implement the various pixel level fusion algorithms and to determine how well the information contained in the source images are represented in the fused images on multimodality and multifocusing images. Experiments and qualitative metrics dictate that Laplacian Pyramid method performs better on both multimodality and multifocusing images.

An efficient leaf recognition algorithm for plant classification using support vector machine 基于支持向量机的植物叶片识别算法
Arunpriya C P S G R, Balasaravanan T, Antony Selvadoss Thanamani
Recognition of plants has become an active area of research as most of the plant species are at the risk of extinction. This paper uses an efficient machine learning approach for the classification purpose. This proposed approach consists of three phases such as preprocessing, feature extraction and classification. The preprocessing phase involves a typical image processing steps such as transforming to gray scale and boundary enhancement. The feature extraction phase derives the common DMF from five fundamental features. The main contribution of this approach is the Support Vector Machine (SVM) classification for efficient leaf recognition. 12 leaf features which are extracted and orthogonalized into 5 principal variables are given as input vector to the SVM. Classifier tested with flavia dataset and a real dataset and compared with k-NN approach, the proposed approach produces very high accuracy and takes very less execution time.

Classifier tested with flavia dataset and a real dataset and compared with k-NN approach, the proposed approach produces very high accuracy and takes very less execution time.","PeriodicalId":148511,"journal":{"name":"International Conference on Pattern Recognition, Informatics and Medical Engineering (PRIME-2012)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129234976","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}
