CRY — An improved crop yield prediction model using bee hive clustering approach for agricultural data sets 基于蜂箱聚类方法的农业数据集作物产量预测模型
M. G. Ananthara, T. Arunkumar, R. Hemavathy
Agricultural researchers over the world insist on the need for an efficient mechanism to predict and improve the crop growth. The need for an integrated crop growth control with accurate predictive yield management methodology is highly felt among farming community. The complexity of predicting the crop yield is highly due to multi dimensional variable metrics and unavailability of predictive modeling approach, which leads to loss in crop yield. This research paper suggests a crop yield prediction model (CRY) which works on an adaptive cluster approach over dynamically updated historical crop data set to predict the crop yield and improve the decision making in precision agriculture. CRY uses bee hive modeling approach to analyze and classify the crop based on crop growth pattern, yield. CRY classified dataset had been tested using Clementine over existing crop domain knowledge. The results and performance shows comparison of CRY over with other cluster approaches.
世界各地的农业研究人员坚持需要一种有效的机制来预测和改善作物生长。农业社区对综合作物生长控制和准确预测产量管理方法的需求高度敏感。由于多维变量指标和预测建模方法的不可用性,导致作物产量预测的复杂性很高,从而导致作物产量损失。本文提出了一种基于动态更新的作物历史数据集的作物产量预测模型(CRY),该模型采用自适应聚类方法来预测作物产量,以提高精准农业的决策水平。CRY采用蜂箱建模方法,根据作物生长模式、产量对作物进行分析分类。CRY分类数据集使用Clementine在现有作物领域知识上进行了测试。结果和性能表明了该方法与其他聚类方法的比较。

Personal approach for mobile search: A review 移动搜索的个性化方法:综述
Amol D. Gaikwad, Ctech Deptt
Web service is a popular standard to publish services for users. However, diversified users need to access web service according to their particular preferences. Mobile search is quite different from standard PC-based web search in a number of ways: (a) the user interfaces and I/O are limited by screen real state, (b) key pads are tiny and inconvenient for use, (c) limited bandwidth and (d) costly connection fees. This review paper focuses on the personalization strategies which explicitly and implicitly infer user search context at individual user level. The paper also focuses on an architecture which collects user information (at mobile device and carrier network) and derives user intention in given situations.
Web服务是为用户发布服务的流行标准。然而,多样化的用户需要根据自己的特定偏好来访问web服务。手机搜索与标准的基于pc的网页搜索在很多方面都有很大的不同:(a)用户界面和I/O受到屏幕实际状态的限制;(b)键盘很小,不方便使用;(c)有限的带宽;(d)昂贵的连接费用。本文主要研究了在个体用户层面上显式和隐式推断用户搜索上下文的个性化策略。本文还重点研究了一种收集用户信息(在移动设备和运营商网络上)并在给定情况下导出用户意图的体系结构。

Outliers detection on protein localization sites by partitional clustering methods 用分割聚类方法检测蛋白质定位位点的异常值
P. Ashok, G. M. Kadhar Nawaz, K. Thangavel, E. Elayaraja
A large molecule composed of one or more chains of amino acids in a specific order, the order is determined by the base sequence of nucleotides in the gene that codes for the protein. Proteins are required for the structure, function, and regulation of the body's cells, tissues, and organs and each protein has unique functions. Localization sites of proteins are identified by the mechanism and moved to its corresponding organelles. In this paper, we introduce the method clustering and its type's K-Means and K-Medoids. The clustering algorithms are improved by implementing the two initial centroid selection methods instead of selecting centroid randomly. K-Means algorithm can be improved by implementing the initial cluster centroids are selected by the two proposed algorithms instead of selecting centroids randomly, which is compared by using Davie Bouldin index measure, hence the proposed algorithm1 overcomes the drawbacks of selecting initial cluster centers then other methods. In the yeast dataset, the defective proteins (objects) are considered as outliers, which are identified by the clustering methods with ADOC (Average Distance between Object and Centroid) function. The outlier's detection method and performance analysis method are studied and compared, the experimental results shows that the K-Medoids method performs well when compare with the K-Means clustering.
一种由一条或多条氨基酸链按特定顺序组成的大分子,其顺序由编码蛋白质的基因中核苷酸的碱基序列决定。蛋白质是人体细胞、组织和器官的结构、功能和调节所必需的,每种蛋白质都有独特的功能。蛋白质的定位位点通过该机制被识别并移动到相应的细胞器上。本文介绍了聚类方法及其K-Means和k - medium类型。通过实现两种初始质心选择方法来改进聚类算法,而不是随机选择质心。K-Means算法可以通过实现由两种算法选择初始聚类质心而不是随机选择质心来改进K-Means算法,并通过Davie Bouldin指数度量进行比较,从而克服了K-Means算法选择初始聚类质心的缺点。在酵母数据集中,将缺陷蛋白(对象)视为离群值,采用ADOC(对象与质心之间的平均距离)函数聚类方法对其进行识别。对离群点检测方法和性能分析方法进行了研究和比较,实验结果表明,与K-Means聚类方法相比,K-Medoids方法具有较好的性能。

Background subtraction based on threshold detection using modified K-means algorithm 基于改进K-means算法阈值检测的背景减法
A. N. Kumar, C. Sureshkumar
In video surveillance systems, background subtraction is the first processing stage and it is used to determine the objects in a particular scene. It is a general term for a process which aims to separate foreground objects from a relatively stationary background. It should be processed in real time. It is obtained in human detection system by computing the variation, pixel-by-pixel, between the current frame and the image of the background, followed by an automatic threshold. This paper proposed a K means based background subtraction for real time video processing in video surveillance. We have analyzed and evaluate the performance of the proposed method, with standard K-means and other background subtractions algorithms. The experimental results showed that the proposed method provides better output.

The selection of the most appropriate network in heterogeneous Wireless environment is one of the critical issues to provide the best Quality of Service (QOS) to the users. The selection of an apt network among various alternatives is a kind of Multi Criteria Decision Making (MCDM) problem. This paper describes a novel Multi Criteria Decision Making (MCDM) method to evaluate and select the suitable network for homogeneous wireless network environment. The proposed MCDM technique involves Fuzzy Analytical Hierarchy Process (FAHP) is integrated with Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) techniques. FAHP is used to determine the criteria weights, whereas TOPSIS and VIKOR used to find the performance ranking of the alternative networks. This study focuses on five network alternatives such as WLAN, GPRS, UMTS, WIMAX, and CDMA and ten evaluation criteria such as bandwidth, latency, jitter, BER, Retransmission, Packet loss, through put, preference, security, cost to select the appropriate network.

A novel approach for speech feature extraction by Cubic-Log compression in MFCC 基于立方对数压缩的MFCC语音特征提取新方法
M. R. Devi, T. Ravichandran
Speech Pre-processing is measured as major step in development of feature vector extraction for an efficient Automatic Speech Recognition (ASR) system. A novel approach for speech feature extraction is by applying the Mel-frequency cepstral co-efficient (MFCC) algorithm using Cubic-Log compression instead of Logarithmic compression in MFCC. In proposed MFCC, the frequency axis is initially warped to the mel-scale which is roughly below 2 kHz and logarithmic above this point. Triangular filter are equally spaced in the mel-scale are applied on the warped spectrum. The result of the filters are compressed using Cubic-Log function and cepstral co-efficient are computed by applying DCT to obtain minimum MFCC feature vector for spoken words. These feature vectors are given as input to classification and Recognition phase. The system is trained and tested by generating MFCC feature vector for 600 isolated words, 256 connected words and 150 sentences in clear and noisy environment. Experiment results shows that with minimum MFCC feature vector is enough for speech recognition system to achieve high recognition rate and its performance is measured based on Mean Square Error (MSE) rate.
语音预处理是实现高效自动语音识别(ASR)系统特征向量提取的重要步骤。一种新的语音特征提取方法是采用三对数压缩代替对数压缩的Mel-frequency倒谱协效率(MFCC)算法。在所提出的MFCC中,频率轴最初被扭曲到梅尔尺度,梅尔尺度大致低于2khz,在该点以上为对数。三角滤波器在梅尔尺度上等距分布,应用于扭曲光谱。利用立方对数函数对滤波结果进行压缩,利用离散余弦变换计算倒谱系数,得到最小的MFCC特征向量。这些特征向量作为分类和识别阶段的输入。通过在清晰和嘈杂的环境中生成600个孤立词、256个连通词和150个句子的MFCC特征向量,对系统进行了训练和测试。实验结果表明,最小的MFCC特征向量足以使语音识别系统获得较高的识别率,并基于均方误差(MSE)率来衡量其性能。

Data property analyzer for information storage in cloud 用于云信息存储的数据属性分析器
S. Srinivasan, R. Krishnan
This paper inscribes a new approach for maintaining the data usage report for the cloud data storage using a novel data property analyzer. Cloud data storage is a technology that uses the internet and central remote servers to maintain data and share the applications. It allows consumer to use applications without installation and access their personal files at any computer with internet access. In general data property analysis system, Source and destination file content is compared in the form of bytes. In the cloud environment, data verification is needed for every computation in the storage correctness. So every time the data is retrieved from local system and compared with the destination file from the cloud zone. This procedure takes too much of time to find out a tiny change in the cloud file content. The proposed system is implemented with the idea of checking the file properties to find out the change in file content instead of verifying the entire file content. To check properties we have taken some of the file attributes such as file size, file modification date, file name and location.
本文介绍了一种使用新型数据属性分析器维护云数据存储数据使用报告的新方法。云数据存储是一种使用互联网和中央远程服务器来维护数据和共享应用程序的技术。它允许消费者在没有安装的情况下使用应用程序,并在任何可以上网的计算机上访问他们的个人文件。在一般的数据属性分析系统中,源文件和目标文件的内容以字节的形式进行比较。在云环境下,存储正确性中的每一次计算都需要进行数据验证。因此,每次从本地系统检索数据并与来自云区域的目标文件进行比较。这个过程花费了太多的时间来发现云文件内容中的微小变化。该系统的实现思路是通过检查文件属性来发现文件内容的变化,而不是对整个文件内容进行验证。为了检查属性,我们已经采取了一些文件属性,如文件大小,文件修改日期,文件名和位置。

Cloud data storage is a technology that uses the internet and central remote servers to maintain data and share the applications. It allows consumer to use applications without installation and access their personal files at any computer with internet access. In general data property analysis system, Source and destination file content is compared in the form of bytes. In the cloud environment, data verification is needed for every computation in the storage correctness. So every time the data is retrieved from local system and compared with the destination file from the cloud zone. This procedure takes too much of time to find out a tiny change in the cloud file content. The proposed system is implemented with the idea of checking the file properties to find out the change in file content instead of verifying the entire file content. To check properties we have taken some of the file attributes such as file size, file modification date, file name and location.","PeriodicalId":123210,"journal":{"name":"2013 International Conference on Pattern Recognition, Informatics and Mobile Engineering","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122223411","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}
