The relation between fuzzy soft set and integrative fuzzy set 模糊软集与综合模糊集的关系
Yi Jiang, Hailiang Zhao, Junxuan He
Fuzzy set can be divided into single parameter or multi-parameter's ones with which to depict their fuzzy attributes. In references, it is usual defined in a single parameter universe and yet multi-parameter's ones often appears in so-called fuzzy relation. Fuzzy soft set can be used to describe a fuzzy object by aggregating fuzzy parameters in different attributes. Fuzzy set can be employed to do the same things. It can be concluded that there must be a certain relation between the two concepts. And to give the relation, integrative fuzzy set is proposed in this paper. And which can be decomposed into a fuzzy soft set under certain condition. Fuzzy soft set also can be translated into an integrative fuzzy set by some operator. Both of them can be used for decision-making. Theoretical analysis and examples show the optimal decision-making results are equivalent.
模糊集可以分为单参数集和多参数集,用来描述它们的模糊属性。在参考文献中,它通常定义在单参数范围内,而多参数范围往往以所谓的模糊关系出现。模糊软集通过对不同属性的模糊参数进行聚合来描述一个模糊对象。模糊集可以用来做同样的事情。可以得出结论,这两个概念之间一定存在某种联系。为了给出二者之间的关系,本文提出了模糊集的概念。在一定条件下可分解为模糊软集。模糊软集也可以通过某种算子转化为一个积分模糊集。两者都可以用于决策。理论分析和算例表明,最优决策结果是等价的。

Indexing biomedical documents with Bayesian networks and terminologies 用贝叶斯网络和术语索引生物医学文献
Wiem Chebil, L. Soualmia, Mohamed Nazih Omri, S. Darmoni
We proposed a new approach denoted SDIBN (Semantic Documents Indexing using Bayesian Networks) for indexing biomedical documents with terminologies. The main contribution of SDIBN is to use Bayesian Networks (BN) and the probability inference to perform a partial match between documents and biomedical concepts. The biomedical terminologies exploited are MeSH (Medical Subject Headings) thesaurus and SNOMED CT (Systematized Nomenclature of Medicine-Clinical Terms). Our approach exploits also UMLS (Unified Medical Language System) to filter the extracted concepts which allows to keep only relevant concepts. Our contribution also is to use DCG(Discount Cumulative Gain) measure for the first time to evaluate the indexing approaches. The experiments of SDIBN which are performed on subsets of OHSUMED and Cismef collections showed encouraging results.
我们提出了一种基于贝叶斯网络的语义文档索引(SDIBN)的生物医学文献索引方法。SDIBN的主要贡献是使用贝叶斯网络(BN)和概率推理在文档和生物医学概念之间进行部分匹配。利用的生物医学术语是MeSH(医学主题词)辞典和SNOMED CT(医学-临床术语系统化命名法)。我们的方法还利用了UMLS(统一医学语言系统)来过滤提取的概念,从而只保留相关的概念。我们的贡献还在于首次使用DCG(折扣累积增益)度量来评估索引方法。在OHSUMED和Cismef集合子集上进行的SDIBN实验取得了令人鼓舞的结果。

Conflicting rate based branching heuristic for CDCL SAT solvers 基于冲突率的分支启发式CDCL - SAT求解方法
Qingshan Chen, Yang Xu, Guanfeng Wu, Xingxing He
The modern SAT solvers usually update score of corresponding variables by increasing a bump value on each conflict. Those values are usually constant, but are independent of decision levels and conflicts. Sometimes, it is more efficient for local conflict optimization but weak in global searching. In this paper, we propose a CRB method (Conflicting Rate Branching), which is a variant of VSIDS but different implementation. The CRB updates the score which integrated with the decision level and conflicts whenever a variable is used in conflict analysis. We integrated CRB with MiniSat solvers and evaluated CRB on instances from the SAT Race 2015. Experimental results show that the proposed strategy can solve more instances than EVSIDS and improve performance for both SAT and UNSAT instances.
现代SAT求解器通常通过增加每个冲突的碰撞值来更新相应变量的分数。这些值通常是恒定的,但与决策级别和冲突无关。有时,局部冲突优化效率更高,但全局搜索效率较低。本文提出了一种冲突速率分支(CRB)方法,它是VSIDS的一种变体,但实现方式不同。当冲突分析中使用某个变量时,CRB将更新与决策水平和冲突相结合的得分。我们将CRB与MiniSat求解器集成在一起,并根据2015年SAT竞赛的实例评估了CRB。实验结果表明,该策略可以解决比EVSIDS更多的实例,并提高了SAT和UNSAT实例的性能。

Diverse activation functions in deep learning 深度学习中的多种激活函数
Bin Wang, Tianrui Li, Yanyong Huang, Huaishao Luo, Dongming Guo, S. Horng
We introduce the concept of diverse activation functions, and apply them into Convolutional Auto-Encoder (CAE) to develop diverse activation CAE (DaCAE), which considerably reduces the reconstruction loss. In contrast to vanilla CAE only with activation functions of the same types, DaCAE incorporates diverse activations by considering their cooperation and location. In terms of the reconstruction capability, DaCAE significantly outperforms vanilla CAE and full connected Auto-Encoder, and we conclude rules of thumb on designing diverse activations networks. Based on the high quality of the latent bottleneck features extracted from DaCAE, we demonstrate a satisfying advantage that fuzzy rules classifier performs better than softmax layer in supervised learning. These results could be seen as new research points in the attempts at using diverse activations to train deep neural networks and combining fuzzy inference systems with deep learning.
我们引入了多种激活函数的概念,并将其应用于卷积自编码器(CAE)中,开发了多种激活CAE (DaCAE),大大减少了重构损失。与仅具有相同类型激活函数的普通CAE相比,DaCAE通过考虑它们的协作性和位置而包含了多种激活。在重建能力方面,DaCAE明显优于普通CAE和全连接的Auto-Encoder,我们总结了设计各种激活网络的经验法则。基于从DaCAE中提取的高质量的潜在瓶颈特征,我们证明了模糊规则分类器在监督学习中优于softmax层的令人满意的优势。这些结果可以被视为尝试使用不同激活来训练深度神经网络以及将模糊推理系统与深度学习相结合的新研究点。

Traffic flow forecasting based on hybrid deep learning framework 基于混合深度学习框架的交通流量预测
Shengdong Du, Tianrui Li, Xun Gong, Yan Yang, S. Horng
Traffic flow forecasting is a key problem in the field of intelligent traffic management. In this work, we propose a hybrid deep learning framework for short-term traffic flow forecasting. It is built by the multi-layer integration deep learning architecture and jointly learns the spatial-temporal features. According to the highly nonlinear and non-stationary characteristics of traffic flow data, the framework consists of Recurrent Neural Networks (RNNs) and Convolutional Neural Networks (CNNs). The former is to capture long temporal dependencies by using Long Short-Term Memory (LSTM) units and the latter is to capture the local trend features. The proposed framework is compared with other traditional shallow and deep learning models for traffic flow forecasting on PeMS datasets. The experimental results indicate that the hybrid framework is capable of dealing with complex nonlinear urban traffic flow forecasting with satisfying accuracy and effectiveness.
交通流预测是智能交通管理领域的一个关键问题。在这项工作中,我们提出了一个用于短期交通流量预测的混合深度学习框架。它由多层集成深度学习架构构建,共同学习时空特征。根据交通流数据高度非线性和非平稳的特点,该框架由递归神经网络(rnn)和卷积神经网络(cnn)组成。前者是利用长短期记忆(LSTM)单元捕捉长时间依赖关系,后者是捕捉局部趋势特征。将该框架与其他传统的浅学习模型和深度学习模型进行了比较。实验结果表明,该混合框架能够处理复杂非线性的城市交通流预测,具有满意的精度和有效性。

Semi-supervised deep network representation with text information 文本信息的半监督深度网络表示
Xinchun Ming, Fangyu Hu
Network representation learning aims at learning low-dimensional representation for each vertex in a network, which plays an important role in network analysis. Con­ventional shallow models often achieve sub-optimal network representation results for non-linear network characteristics. Most network representation methods merely concentrate on structure but ignore text information related to each node. In the paper, we propose a novel semi-supervised deep model for network representation learning. We adopt a random surfing model to capture the global structure and incorporate text features of vertices based on the PV-DBOW model. The joint similarity between vertices achieved by combining network structure and text information is applied as the unsupervised component. While the first-order proximity in a network is used as the supervised component. By jointly optimizing them, our method can obtain reliable low-dimensional vector representations. The experiments on two real-world networks show that our method outperforms other baselines in the task of multi-class classification of vertices.
网络表示学习的目的是学习网络中每个顶点的低维表示,在网络分析中起着重要的作用。对于非线性网络特征,传统的浅层模型往往不能得到最优的网络表示结果。大多数网络表示方法只关注结构,而忽略了与每个节点相关的文本信息。在本文中,我们提出了一种新的半监督深度网络表示学习模型。在PV-DBOW模型的基础上,采用随机冲浪模型捕获全局结构,并结合顶点的文本特征。将网络结构与文本信息结合得到的顶点间的联合相似度作为无监督分量。而网络中的一阶接近度被用作监督分量。通过对它们的联合优化,我们的方法可以获得可靠的低维向量表示。在两个真实网络上的实验表明,我们的方法在对顶点进行多类分类的任务中优于其他基线。

Classification of diabetic retinopathy using textural features in retinal color fundus image 利用视网膜彩色眼底图像的纹理特征对糖尿病视网膜病变进行分类
A. Padmanabha, Abhishek M. Appaji, M. Prasad, H. Lu, Sudhanshu Joshi
Early, diagnosis is essential for diabetic patients to avoid partial or complete blindness. This work presents a new analysis method of texture features for classification of Diabetic Retinopathy (DR). The proposed method masks the blood vessels and optic disk segmented and directly extracts the textural features from the remaining retinal region. The proposed method is much simpler with comparison of the other methods that detect the defective regions first and then extract the required features for classification. The Haralick texture measures calculated are used for classification of DR. The proposed method is evaluated through a classification of DR using both Support Vector Machine (SVM) and Artificial Neural Network (ANN). The results of SVM have a better accuracy (87.5%) over ANN (79%). The performance of the proposed method is presented also in terms of sensitivity and specificity.
早期诊断对于糖尿病患者避免部分或完全失明至关重要。本文提出了一种新的纹理特征分析方法用于糖尿病视网膜病变(DR)的分类。该方法对分割后的血管和视盘进行掩盖,直接提取剩余视网膜区域的纹理特征。与其他先检测缺陷区域,然后提取所需特征进行分类的方法相比,该方法简单得多。利用计算得到的Haralick纹理测度对DR进行分类,并结合支持向量机(SVM)和人工神经网络(ANN)对DR进行分类。SVM的准确率为87.5%,优于人工神经网络(79%)。本文还从灵敏度和特异性两方面介绍了该方法的性能。

Modeling and validation for embedded software confidentiality and integrity 嵌入式软件保密性和完整性的建模和验证
Xinwen Hu, Zhuang Yi, Zining Cao, Tong Ye, Mi Li
With the rapid development of embedded software, embedded software has a highly security demand, such as confidentiality and integrity. UML provides the foundation for the construction and analysis of embedded software, but it cannot provide accurate semantics for the validation of embedded software security properties. Using the formal method based on Z language to model the security properties of embedded software, can provide the rigorous semantics for the security properties of embedded software, which can help to discover its early design errors and reduce the cost of testing and maintenance. Developing the model transformation tool of UML model to Z model, which can avoid repetitive modeling of the manual establishment of Z model, reduce the possibility of introducing artificial logic error in the model. Verifying the correctness of the confidentiality and integrity model by using the formal verification tool Z/EVES, which can make the embedded software satisfy the user's security requirement. This paper construct the static structure model and dynamic behavior model of embedded software confidentiality and integrity modeling based on Z at first; and then establish the model transformation rules of UML modeling elements to Z modeling elements, which is designed and implemented based on the XSLT technology; finally, the formal model is validated by using the verification tool Z/EVES through the example of a bicycle parking embedded software, and the correctness of the embedded software security model presented in this paper is explained.
随着嵌入式软件的快速发展,嵌入式软件对保密性、完整性等安全性要求很高。UML为嵌入式软件的构建和分析提供了基础,但是它不能为嵌入式软件安全属性的验证提供准确的语义。采用基于Z语言的形式化方法对嵌入式软件的安全属性进行建模,可以为嵌入式软件的安全属性提供严格的语义,有助于早期发现其设计错误,降低测试和维护成本。开发了UML模型到Z模型的模型转换工具,避免了手工建立Z模型的重复建模,减少了模型中引入人为逻辑错误的可能性。利用Z/EVES形式化验证工具验证机密性和完整性模型的正确性,使嵌入式软件满足用户的安全需求。本文首先建立了基于Z的嵌入式软件机密性和完整性建模的静态结构模型和动态行为模型;建立了UML建模元素到Z建模元素的模型转换规则,并基于XSLT技术进行了设计与实现;最后,利用验证工具Z/EVES,通过一个自行车停放嵌入式软件的实例,对形式化模型进行了验证,说明了本文提出的嵌入式软件安全模型的正确性。

Using the formal method based on Z language to model the security properties of embedded software, can provide the rigorous semantics for the security properties of embedded software, which can help to discover its early design errors and reduce the cost of testing and maintenance. Developing the model transformation tool of UML model to Z model, which can avoid repetitive modeling of the manual establishment of Z model, reduce the possibility of introducing artificial logic error in the model. Verifying the correctness of the confidentiality and integrity model by using the formal verification tool Z/EVES, which can make the embedded software satisfy the user's security requirement. This paper construct the static structure model and dynamic behavior model of embedded software confidentiality and integrity modeling based on Z at first; and then establish the model transformation rules of UML modeling elements to Z modeling elements, which is designed and implemented based on the XSLT technology; finally, the formal model is validated by using the verification tool Z/EVES through the example of a bicycle parking embedded software, and the correctness of the embedded software security model presented in this paper is explained.","PeriodicalId":208009,"journal":{"name":"2017 12th International Conference on Intelligent Systems and Knowledge Engineering (ISKE)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130459501","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}
