The ability of Ethernet Ring Protection Switching (ERPS) to provide carrier grade switchover has made Ethernet technology viable in telecommunication carrier networks enabling network operators to replace SONET/SDH/PDH. Adaptive modulation (AM) is another evolution in technology which may effectively double the capacity of microwave links in favorable weather condition. In this paper, we propose an enhancement of ERPS protocol to support adaptive modulation in ERPS protected microwave access network for improved throughput, reliability and energy efficiency. We present a mathematical model to verify the effectiveness of our proposed modification. Simulation results show that the proposed enhancement achieves significantly higher throughput compared to existing ITU-T G.8032 protocol in varying channel conditions.
以太网环保护交换(ERPS)提供载波级切换的能力使以太网技术在电信运营商网络中可行,使网络运营商能够取代SONET/SDH/PDH。自适应调制(AM)是另一项技术的发展,它可以在有利的天气条件下有效地使微波链路的容量翻倍。在本文中,我们提出了一种增强ERPS协议,以支持ERPS保护的微波接入网中的自适应调制,以提高吞吐量、可靠性和能源效率。我们提出了一个数学模型来验证我们所提出的修改的有效性。仿真结果表明,在不同信道条件下,与现有的ITU-T G.8032协议相比,该增强协议的吞吐量显著提高。

Barreto-Naehrig (BN) curve is a well studied pairing friendly curve of embedding degree 12, that uses arithmetic in Fpi2. Therefore the arithmetic of Fp12 extension field is well studied. In this paper, we have proposed an efficient approach of arithmetic operation over the extension field of degree 18 by towering. Fp18 extension field arithmetic is considered to be the basis of implementing the next generation pairing based security protocols. We have proposed to use Fp element to construct irreducible binomial for building tower of extension field up to Fp6, where conventional approach uses the root of previous irreducible polynomial to create next irreducible polynomials. Therefore using Fp elements in irreducible binomial construction, reduces the number of multiplications in Fp to calculate inversion and multiplication over Fp18, which effects acceleration in total arithmetic operation over Fp18.
Barreto-Naehrig (BN)曲线是一种嵌入度为12的配对友好曲线,在Fpi2中使用了算法。因此,对Fp12扩展域的算法进行了深入的研究。在本文中,我们提出了一种有效的18次参天扩展域的算术运算方法。Fp18扩展域算法被认为是实现下一代基于配对的安全协议的基础。我们提出使用Fp元素构造不可约二项式来构建Fp6以下的扩展域塔,而传统方法使用前一个不可约多项式的根来创建下一个不可约多项式。因此,在不可约二项结构中使用Fp元素,可以减少Fp18上计算反转和乘法的Fp乘法次数,从而影响Fp18上总算术运算的加速。

The demand of text classification is growing significantly in web searching, data mining, web ranking, recommendation systems and so many other fields of information and technology. This paper illustrates the text classification process on different dataset using some standard supervised machine learning techniques. Text documents can be classified through various kinds of classifiers. Labeled text documents are used to classify the text in supervised classifications. This paper applied these classifiers on different kinds of labeled documents and measures the accuracy of the classifiers. An Artificial Neural Network (ANN) model using Back Propagation Network (BPN) is used with several other models to create an independent platform for labeled and supervised text classification process. An existing benchmark approach is used to analysis the performance of classification using labeled documents. Experimental analysis on real data reveals which model works well in terms of classification accuracy.

Recommendation systems use utility matrix to represent the user ratings for a particular items. But that matrix is sparse, that is, most of the user ratings are unknown. Predicting those unknown ratings is a big challenge of recommendation data mining task. Due to the sparse of data in utility matrix, few features become less important. Those features should be reduced to decline the computational complexity. Singular Value Decomposition (SVD) is a most powerful algorithm to predict unknown ratings by reducing the less significant features. Before applying SVD on utility matrix, all unknown ratings should be filled with some initial values. This paper focuses to generate two predictive matrixes by assigning two different initial values, where one is Zero and other is replacing unknown values with average item rating and then subtracting corresponding average user rating from the values. The accuracy of forecasted ratings has been justified over a sample dataset in this paper as well.
推荐系统使用效用矩阵来表示用户对特定项目的评分。但是这个矩阵是稀疏的,也就是说,大多数用户的评分是未知的。预测这些未知的评级是推荐数据挖掘任务的一大挑战。由于效用矩阵中数据的稀疏性,一些特征变得不那么重要。应该减少这些特征以降低计算复杂度。奇异值分解(SVD)是一种通过减少不太重要的特征来预测未知评级的最强大的算法。在对效用矩阵应用奇异值分解之前,所有未知的评级都应该用一些初始值填充。本文的重点是通过分配两个不同的初始值来生成两个预测矩阵,其中一个是0,另一个是用平均物品评分替换未知值,然后减去相应的平均用户评分。预测评级的准确性也在本文的样本数据集上得到了证明。

Sentiment is the only things that separate human and machine. To simulate the feelings for machines many researchers have been trying to create method and automated the process to extract opinion of particular news, product or life entity. Sentiment Analysis (SA) is a combination of opinions, emotions and subjectivity of a text. Currently SA is the most demanding task in Natural Language Processing. Social networking site like Facebook are mostly used in expressing the opinions about a particular entity of life. Newspaper published news about a particular event and user expressed their feedback in news comments. Online product feedback is increasing day by day. So reviews and opinions mining play a very important role in understanding people satisfactions. Such opinion mining has potential for knowledge discovery. The main target of SA is to find opinions from text extract sentiments from them and define their polarity, i.e positive or negative. In this domain most of the model was designed for English Language. This paper describes a novel approach using Naive Bayes classification model for Bengali Language. Here a supervised classification method is used with language rules for detecting sentiment for Bengali Facebook Status.
情感是人类和机器的唯一区别。为了模拟机器的感受,许多研究人员一直在尝试创造方法并自动化提取特定新闻,产品或生命实体的意见。情感分析是对语篇的观点、情感和主观性的综合分析。自然语言分析是当前自然语言处理中要求最高的任务。像Facebook这样的社交网站主要用于表达对特定生活实体的看法。报纸刊登关于某一特定事件的新闻,用户在新闻评论中表达他们的反馈。在线产品反馈日益增多。所以评论和意见挖掘在理解人们的满意度方面起着非常重要的作用。这种意见挖掘具有知识发现的潜力。语篇分析的主要目标是从文本中寻找观点,从中提取情感,并确定其极性,即积极或消极。在这个领域中,大多数模型是为英语语言设计的。本文描述了一种利用朴素贝叶斯分类模型对孟加拉语进行分类的新方法。这里使用监督分类方法和语言规则来检测孟加拉语Facebook状态的情绪。

Recognition of handwritten numerals has gained much interest in recent years due to its various application potentials. Bangla is a major language in Indian subcontinent and is the first language of Bangladesh; but unfortunately, study regarding handwritten Bangla numeral recognition (HBNR) is very few with respect to other major languages such as English, Roman etc. Some noteworthy research works have been conducted for recognition of Bangla handwritten numeral using artificial neural network (ANN) as ANN and its various updated models are found to be efficient for classification task. The aim of this study is to develop a better HBNR system and hence investigated deep architecture of stacked auto encoder (SAE) incorporating printed text (SAEPT) method. SAE is a variant of neural networks (NNs) and is applied efficiently for hierarchical feature extraction from its input. The proposed SAEPT contains the encoding of handwritten numeral into printed form in the course of pre-training and finally initializing a multi-layer perceptron (MLP) using these pre-trained weights. Unlike other methods, it does not employ any feature extraction technique. Benchmark dataset with 22000 hand written numerals with different shapes, sizes and variations are used in this study. The proposed method is shown to outperform other prominent existing methods achieving satisfactory recognition accuracy.
近年来,手写体数字识别由于具有多种应用潜力而引起了人们的广泛关注。孟加拉语是印度次大陆的主要语言,也是孟加拉国的第一语言;但不幸的是,关于手写孟加拉数字识别(HBNR)的研究很少,相对于其他主要语言,如英语,罗马语等。人工神经网络及其各种更新模型在孟加拉语手写体数字识别方面取得了一些值得关注的研究成果。本研究的目的是开发一个更好的HBNR系统,因此研究了结合印刷文本(SAEPT)方法的堆叠式自动编码器(SAE)的深度架构。SAE是神经网络(NNs)的一种变体,可以有效地从其输入中提取分层特征。所提出的SAEPT包括在预训练过程中将手写数字编码为打印形式,最后使用这些预训练的权重初始化多层感知器(MLP)。与其他方法不同,它不使用任何特征提取技术。本研究使用了22000个不同形状、大小和变化的手写数字的基准数据集。结果表明,该方法优于现有的其他主要方法,取得了令人满意的识别精度。

The proposed method is shown to outperform other prominent existing methods achieving satisfactory recognition accuracy.","PeriodicalId":287635,"journal":{"name":"2016 19th International Conference on Computer and Information Technology (ICCIT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129581648","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}

Ability to allocate task on the fly is considered to be one of the most desirable features in a swarm intelligent system. This paper presents a computational model in which swarms of autonomous agents (robots) carry out the task of cleaning the environment by collecting boxes from the environment and dumping them in a dump area. As agents work, they lose energy and when the energy is too low they need to go to the charging area to gain energy. Our model is inspired by how social insects and in particular how ants behave. Experimental results show that incorporating trophallactic behavior in swarms of robots improve the performance of the swarm in terms of the energy consumption over earlier strategies. The proposed model is found to be efficient, accurate and consistent with the biological equivalents.
动态分配任务的能力被认为是群智能系统最理想的特征之一。本文提出了一个计算模型,在该模型中,一群自主智能体(机器人)通过从环境中收集盒子并将它们倾倒在倾倒区域来执行清洁环境的任务。当智能体工作时,它们会失去能量,当能量过低时,它们需要去充电区域获取能量。我们的模型受到群居昆虫的启发,尤其是蚂蚁的行为。实验结果表明,与早期策略相比,在机器人群体中加入营养行为可以提高群体的能量消耗性能。所提出的模型是有效的,准确的,并与生物当量一致。
