Super-resolution: Sparse dictionary design method using quantitative comparison 超分辨率:采用定量比较的稀疏字典设计方法
Marwa Moustafa, H. M. Ebeid, A. Helmy, Taymoor M. Nazamy, M. Tolba
Single image super resolution (SISR) is the process that obtains a high resolution image from a single low resolution (LR) image by increasing the high frequency information and removing the degradation of the noise. Sparse representation of signal assumes linear combinations of a few atoms from a pre -specified dictionary. Sparse representation has been used successfully as a prior in signal reconstruction. Dictionary design is crucial for the success of reconstruction high resolution images. This paper evaluates the performance of dictionary design models in both mathematical and learning based models, it also compares the wavelet method, Haar method, DCT method, MOD method and K-SVD method. Various experiments are conducted using a real SPOT-4 satellite image. Experimental results demonstrate that the learning based approaches are very effective in increasing resolution and compare favorably to mathematical based approaches.
单幅图像超分辨率(SISR)是通过增加高频信息和消除噪声的退化,从单幅低分辨率图像中获得高分辨率图像的过程。信号的稀疏表示假定来自预先指定的字典的几个原子的线性组合。稀疏表示已被成功地用作信号重构的先验算法。字典设计对于高分辨率图像的成功重建至关重要。本文对基于数学和基于学习的词典设计模型的性能进行了评价,并对小波方法、Haar方法、DCT方法、MOD方法和K-SVD方法进行了比较。利用真实的SPOT-4卫星图像进行了各种实验。实验结果表明,基于学习的方法在提高分辨率方面非常有效,并且优于基于数学的方法。

MinCAR-Classifier for classifying lung cancer gene expression dataset 肺癌基因表达数据集的mincar分类器
Wael Zakaria, Y. Kotb, F. Ghaleb
DNA microarray technology assists researchers to learn more about different diseases especially the study of the cancer diseases. Using the microarray technology, it will be possible for the researchers to further classify the types of cancer on the basis of the patterns of gene activity (gene expression) in the tumor cells. This will tremendously help the pharmaceutical community to develop more effective drugs as the treatment strategies will be targeted directly to the specific type of cancer. The classification technique is one of the important data mining techniques that is used for classifying the DNA microarray datasets. The aim of this paper is to build an accurate classifier framework called MinCAR-Classifier that mines all minimal high confident class association rules, MinCAR, from cancer microarray datasets. Based on lung cancer microarray dataset, the comparative studies show that our proposed MinCAR-Classifier framework is more accurate than other well-known classifier frameworks.

A. Kleschev, S. Smagin
The paper provides an introduction into the area of inductive formation of knowledge bases. It presents traditional definitions of main problems in this area and highlights the current topical questions including the interpretability of the results. For solving of current problems in defined area the method of inductive formation of easily interpretable medical diagnostic knowledge bases is suggested. It includes the new definitions of classification and clustering problems for dependence models with parameters and the learning algorithm (solving mentioned problems in their new definitions) developed for the practically useful and easily interpretable mathematical dependence model with parameters which is a near real-life ontology of medical diagnostics (defined by a system of logical relationships with parameters). Also it includes the software package InForMedKB (INductive FORmation of MEDical Knowledge Bases) which implements above mentioned learning algorithm. InForMedKB allows to create training sets (consisting of clinical histories from various therapeutic areas) and to use them for inductive formation of medical diagnostic knowledge bases. These knowledge bases are presented in form accepted in the medical literature and contain descriptions of diseases (from specified therapeutic areas) as well as an explanation of these knowledge bases based on descriptions of clinical histories from used training sets. The formal representation of medical knowledge bases enables their usage for intelligent systems for medical diagnostics.

Accurate individualized therapeutic plans ontology based on evidence based medicine 基于循证医学的准确个体化治疗方案本体
Asmaa A. Alkhouly, A. Mancy, Khaled El-Bahnasy, M. AbdEl-Azeem
Overflow of medical information, lack of knowledge about medications and clinical experience could cause health care professionals to disregard vital information which affects patient safety. Health care professionals should base their decisions on the best-updated evidence for diagnosis, prognosis, and therapeutics, and on patient values and preferences as well as on the results of the clinical experience of both the professional and patient. Such practice is called evidence-based medicine.
医疗信息泛滥、缺乏药物知识和临床经验可能导致医疗保健专业人员忽视影响患者安全的重要信息。卫生保健专业人员的决策应基于最新的诊断、预后和治疗证据,以及患者的价值观和偏好,以及专业人员和患者的临床经验结果。这种做法被称为循证医学。

Evolutionary-based hybrid algorithm for 2D cutting stock problem 二维切料问题的进化混合算法
M. Fathy, M. Osama, M. El-Mahallawy
Cutting stock problem (CSP) affects cost of production and stock use efficiency in many industries. The majority of such industries handle stock of raw material in sheet form with the priority of waste reduction. Thus, in this paper we study the two-dimensional CSP (2-D CSP) with main goal of minimizing trim loss. Current approaches are primarily designed to deal with regular stock sheets only and do not handle irregular or defective sheets. That is why the problem is considered to be partially solved from an industrial stand point. In this paper, we introduce a novel algorithm for 2D CSP to minimize the waste and address the issue of defective and/or irregular stock sheets. The algorithm utilizes image processing, evolutionary-programming (EP), and Linear programming (LP) to form a practical solution. Detection & Isolation of sheets' defects and conversion of irregular sheets to regular is accomplished by image processing. Further processing is done by the remaining techniques to efficiently minimize the waste. Experimental results show that the proposed algorithm succeeds in achieving lower waste values compared to conventional EP algorithms.
切削库存问题影响着许多行业的生产成本和库存利用效率。大多数这类工业处理以单张形式储存的原材料,优先考虑减少浪费。因此,在本文中,我们研究二维CSP (2-D CSP)的主要目标是最小化修剪损失。目前的方法主要是设计来处理正常的库存单,而不处理不规则或有缺陷的单。这就是为什么从工业的角度来看,这个问题被认为部分解决了。在本文中,我们介绍了一种新的二维CSP算法,以最大限度地减少浪费,并解决不良和/或不规则库存单的问题。该算法利用图像处理、进化规划(EP)和线性规划(LP)来形成一个实用的解决方案。通过图像处理实现板材缺陷的检测与隔离,将不规则板材转化为规则板材。进一步的处理由剩余的技术来完成,以有效地减少浪费。实验结果表明,与传统的EP算法相比,该算法可以获得更低的浪费值。

A novel energy efficient vice Cluster Head routing protocol in Wireless Sensor Networks 无线传感器网络中一种新型节能副簇头路由协议
Tawfik Abdel Hakam Hassan, G. Selim, R. Sadek
In Wireless Sensor Networks (WSN) with a clustered hierarchical structure, Cluster-Head (CH) nodes are considered the interface between the leaf normal sensors and the Base Station (BS). The energy dissipation of the sensors, whatever their type, can be optimized by a load balancing in the packet TX/RX process in order to prolong the network lifetime and minimize the advertisement phase time for cluster head selection in each round of the LEACH-C protocol. This paper proposes a routing protocol for LEACH_C WSN in which the system lifetime can be extended by assigning a vice cluster head (VCH) to each of the CHs. Unlike other different VCH based protocols, the assigned VCH doest not remain in the idle state and receive its responsibility by the death of the CH, rather the VCH shares the TX/RX load with its CH in order to balance the load distribution, shortly after the death of the CH a VCH is fully loaded until a new VCH receives the TX load. The simulation results confirm that the theoretically expected results. The functionality of the proposed protocol is tested under different simulation conditions such as the size of the WSN field and the results of simulation prove that the proposed protocol prolongs the network lifetime as expected.
在具有聚类分层结构的无线传感器网络(WSN)中,簇头(CH)节点被认为是叶子法向传感器与基站(BS)之间的接口。无论哪种类型的传感器,都可以通过数据包TX/RX过程中的负载平衡来优化其能量消耗,以延长网络生命周期并最小化每轮LEACH-C协议中簇头选择的公告阶段时间。本文提出了一种LEACH_C无线传感器网络的路由协议,该协议通过为每个簇头分配一个副簇头(VCH)来延长系统的生存期。与其他不同的基于VCH的协议不同,分配的VCH不会保持在空闲状态,并在CH死亡时接收其责任,而是VCH与其CH共享TX/RX负载以平衡负载分配,在CH死亡后不久,VCH被完全加载,直到新的VCH接收TX负载。仿真结果证实了理论预期的结果。在WSN字段大小等不同的仿真条件下对所提协议的功能进行了测试,仿真结果证明所提协议如预期的那样延长了网络生存期。

Ranking of news items in rule-stringent social media based on users' importance: A social computing approach 基于用户重要性的严格规则的社交媒体新闻项目排名:一种社会计算方法
K. Ntalianis, Abdel-badeeh M. Salem
In this paper an innovative social media news items ranking scheme is proposed. The proposed unsupervised architecture takes into consideration user-content interactions, since social media posts receive likes, comments and shares from friends and other users. Additionally the importance of each user is modeled, based on an innovative algorithm that borrows ideas from the PageRank algorithm. Finally, a novel content ranking component is introduced, which ranks posted news items based on a social computing method, driven by the importance of the social network users that interact with them. Initial experiments on real life social networks news items illustrate the promising performance of the proposed architecture. Additionally comparisons with three different ranking ways are provided (SUMF, RSN-CO and RSN-nCO), in terms of user satisfaction.

A business intelligent technique for sentiment estimation by management sectors 一种用于管理部门情绪估计的商业智能技术
S. Rady
People express emotions in response to everyday situation and personal communication. With diversity of language expressions, it is challenging to provide an accurate estimation of emotion or sentiment. This paper proposes intelligent technique and system for sentiment estimation and prediction in the business domain. It is useful for management sectors where tools can automatically analyze collected data and reveal employees' opinion about their organization, or any ongoing topic. The challenge in this work is to detect sentiment classes from relatively long text, where writers merge sentences and expressions when asked to write reviews, instead of being directly asked to write their sentiment degree. The approach is data-driven, which uses machine learning to train classifier features to recognize the sentiment. A system is implemented and tested (on real data collected from employee reviews at big IT organizations) towards two and five classification degrees problems. Recorded results prove efficiency of the technique.
人们表达情绪是对日常情况和个人交流的反应。由于语言表达的多样性,提供对情感或情绪的准确估计是具有挑战性的。本文提出了商业领域情感估计和预测的智能技术和系统。对于管理部门来说,它很有用,因为工具可以自动分析收集的数据,并揭示员工对其组织或任何正在进行的主题的看法。这项工作的挑战在于从相对较长的文本中检测情感类别,其中作者在被要求写评论时合并句子和表达,而不是直接被要求写他们的情感程度。该方法是数据驱动的,它使用机器学习来训练分类器特征来识别情感。系统的实现和测试(基于从大型IT组织的员工评论中收集的真实数据)针对两个和五个分类等级问题。记录结果证明了该技术的有效性。

The goal is to enhance the provision of information via program websites by standardized semantic annotation based on a domain-specific ontology. Starting with a description of the knowledge domain, the paper discusses different solution approaches and outlines a system design for the chosen approach. The basic technical feasibility of the system is shown in a proof of concept. The paper ends with a short survey of further work, comprising research and development tasks, as well as social and management tasks.
