Answering climate change challenges, the paper proposes an intelligent decision support system (DSS) for the management of green-blue infrastructure (GBI). Addressing the gaps identified in other studies, the designed DSS incorporates four key elements: 1/interdisciplinary collaboration among all stakeholders 2/inclusion of practical operation and maintenance activities, 3/main components of distributed DSS, with practical examples of use, 4/consideration of conditions specific to the location. The multi-layered DSS architecture can be implemented as a unified platform that provides a comprehensive, customizable, and flexible framework based on AI tools, big data and analytics, edge computing, cloud, and mobile, IIoT, and biometric system tools. The use of cobots and digital clones alongside humans results in the implementation of hybrid human-machine units. DSS for GBI increases decision-making capacity and can serve as a foundation for the implementation of similar systems by governments and local communities to build sustainable and resilient communities.

With the advent of the information age, the iterative speed of software update is gradually accelerating which makes software development severely limited by software testing. Test case prioritization is an effective way to accelerate software testing progress. With the introduction of heuristic algorithm to this task, the processing efficiency of test cases has been greatly improved. However, to overcome the shortcomings of slow convergence speed and easy fall into local optimum, the improved whale optimization algorithm is proposed for test case prioritization. Firstly, a model called n-dimensional directed search space is established for the swarm intelligence algorithm. Secondly, the enhanced whale optimization algorithm is applied to test case prioritization while the backtracking behavior is conducted for individuals when hitting the wall. In addition, a separate storage space for Pareto second optimization is also designed to filter the optimal solutions of the multi-objective tasks. Finally, both single-objective and multi-objective optimization experiments are carried out for open source projects and real-world projects, respectively. The results show that the improved whale optimization algorithm using n-dimensional directed search space is more conducive to the decisions of test case prioritization with fast convergence speed.
随着信息时代的到来,软件更新的迭代速度逐渐加快,这使得软件开发受到软件测试的严重限制。测试用例优先级是加快软件测试进度的有效方法。在该任务中引入启发式算法,极大地提高了测试用例的处理效率。然而,为了克服收敛速度慢、容易陷入局部最优的缺点,提出了改进的鲸鱼优化算法进行测试用例的优先级排序。首先,建立了群智能算法的n维有向搜索空间模型;其次,应用增强型鲸鱼优化算法对测试用例进行优先级排序,同时对个体在撞墙时进行回溯行为。此外,还为Pareto二次优化设计了单独的存储空间,用于过滤多目标任务的最优解。最后,分别针对开源项目和现实项目进行了单目标和多目标优化实验。结果表明,采用n维有向搜索空间的改进鲸鱼优化算法更有利于测试用例优先级的决策,收敛速度快。

The measurement of uncertainty has been an important topic of research. In Dempster’s framework, Deng entropy serves as a reliable tool for such measurements. However, it fails to consider more comprehensive information, resulting in the loss of critical data. An improved belief entropy is proposed in this paper, which preserves all the merits of Deng entropy. When there is only a single element, it can be degraded to Shannon entropy. When dealing with multiple elements, the partitioning method employed for mass functions makes it more responsive and efficient than alternative measures of uncertainty. Some numerical examples are given to further illustrate the effectiveness and applicability of the proposed entropy measure. Additionally, a case study is conducted on software risk analysis, demonstrating the practical value and relevance of the proposed method in real-world scenarios.
不确定度的测量一直是一个重要的研究课题。在登普斯特的框架中,邓熵作为一种可靠的测量工具。然而,它没有考虑到更全面的信息,导致关键数据的丢失。本文提出了一种改进的信念熵,它保留了邓熵的优点。当只有一个元素时,它可以退化为香农熵。当处理多个元素时,质量函数所采用的分划方法比其他不确定度度量方法反应更快,效率更高。数值算例进一步说明了所提出的熵测度的有效性和适用性。此外,还对软件风险分析进行了案例研究,证明了该方法在实际场景中的实用价值和相关性。

Business Analytics – which unites Descriptive, Predictive and Prescriptive Analytics – represents an important component in the framework of Big Data. It aims to transform data into information, enabling improvements in making decisions. Within Big Data, optimization is mostly related to the prescriptive analysis, but in this paper, we present one of its applications to a predictive analysis based on regression in fuzzy environment.The tools offered by a regression analysis can be used either to identify the correlation of a dependency between the observed inputs and outputs; or to provide a convenient approximation to the output data set, thus enabling its simplified manipulation. In this paper we introduce a new approach to predict the outputs of a fuzzy in – fuzzy out system through a fuzzy regression analysis developed in full accordance to the extension principle. Within our approach, a couple of mathematical optimization problems are solve for each desired α−level. The optimization models derive the left and right endpoints of the α−cut of the predicted fuzzy output, as minimum and maximum of all crisp values that can be obtained as predicted outputs to at least one regression problem with observed crisp data in the α−cut ranges of the corresponding fuzzy observed data. Relevant examples from the literature are recalled and used to illustrate the theoretical findings.
商业分析——将描述性、预测性和规范性分析结合在一起——是大数据框架中的一个重要组成部分。它旨在将数据转化为信息,从而改进决策。在大数据中,优化主要与规定性分析相关,但在本文中,我们提出了它在模糊环境下基于回归的预测分析中的一个应用。回归分析提供的工具可以用来确定观察到的输入和输出之间的依赖关系;或者为输出数据集提供方便的近似值,从而简化操作。本文介绍了一种完全按照可拓原理发展的模糊回归分析方法来预测模糊输入-模糊输出系统的输出。在我们的方法中,为每个期望的α−水平解决了几个数学优化问题。优化模型推导出预测模糊输出的α - cut的左端点和右端点,作为至少一个回归问题的预测输出中所有脆度值的最小值和最大值,这些回归问题具有相应模糊观测数据的α - cut范围内的观测脆度数据。回顾了文献中的相关例子,并使用它们来说明理论发现。

Friend Recommendation Engine for Facebook Users via Collaborative Filtering 通过协同过滤的Facebook用户好友推荐引擎
Pub Date : 2023-04-03 DOI: 10.15837/ijccc.2023.2.4998

Today’s internet consists of an abundant amount of information that makes it difficult for recommendation engines to produce satisfying outputs. This huge stream of unrelated data increases its sparsity, which makes the recommender system’s job more challenging. Facebook’s main recommendation task is to recommend a friendship connection based on the idea that a friend of a friend is also a friend; however, the majority of recommendations using this approach lead to little to no interaction. We propose a model using the matrix factorization technique that leverages interactions between Facebook users and generates a list of friendship connections that are very likely to be interactive. We tested our model using a real dataset with over 33 million interactions between users. The accuracy of the proposed algorithm is measured using the error rate of the predicted number of interactions between possible friends in comparison to the actual values.
今天的互联网包含了大量的信息,这使得推荐引擎很难产生令人满意的输出。这种巨大的不相关数据流增加了它的稀疏性,这使得推荐系统的工作更具挑战性。Facebook的主要推荐任务是基于“朋友的朋友也是朋友”这一理念来推荐朋友关系;然而,使用这种方法的大多数建议几乎没有交互。我们提出了一个使用矩阵分解技术的模型,利用Facebook用户之间的互动,并生成一个很可能是互动的友谊联系列表。我们使用真实的数据集测试了我们的模型,其中包含了用户之间超过3300万次的交互。所提出的算法的准确性是用预测的可能朋友之间的互动次数与实际值的错误率来衡量的。

The ranking of intuitionistic fuzzy numbers is paramount in the decision making process in a fuzzy and uncertain environment. In this paper, a new ranking function is defined, which is based on Robust’s ranking index of the membership function and the non-membership function of trapezoidal intuitionistic fuzzy numbers. The mentioned function also incorporates a parameter for the attitude of the decision factors. The given method is illustrated through several numerical examples and is studied in comparison to other already-existent methods. Starting from the new classification method, an algorithm for solving fuzzy multi-criteria decision-making (MCDM) problems is proposed. The application of said algorithm implies accepting the subjectivity of the deciding factors, and offers a clear perspective on the way in which the subjective attitude influences the decision-making process. Finally, a MCDM problem is solved to outline the advantages of the algorithm proposed in this paper.

Video transmission using sensor networks plays a most significant role in industrial and surveillance applications. Multimedia transmission is also a challenging task in case of guaranteeing quality of service in conditions like limited bandwidth, high congestion, multi-hop routing, etc. Cross layer approach is carried out to handle multimedia transmission over sensor networks for improving network adaptivity. Cross layer based energy aware and packet scheduling algorithm is proposed here to reduce congestion ratio and to improve link quality between the routing nodes. Link quality estimation among nodes is done using Semi-Markov process. Node congestion rate is determined for identifying node’s data channel rate. Packet scheduling process determines the highly prioritized packets by using queue scheduler component thereby the active nodes are selected through link quality process and the packets are transmitted to sink based on prioritize level. Simulation analysis is carried out and the efficiency of the proposed mechanism is proved to be better while comparing with the conventional schemes.
利用传感器网络进行视频传输在工业和监控应用中发挥着重要作用。在带宽有限、拥塞严重、路由多跳等条件下,要保证服务质量,多媒体传输也是一项具有挑战性的任务。采用跨层方法处理传感器网络上的多媒体传输,提高网络自适应能力。为了降低拥塞率,提高路由节点间的链路质量,提出了基于跨层能量感知和分组调度算法。节点间的链路质量估计采用半马尔可夫过程。节点拥塞率用于识别节点的数据通道速率。数据包调度过程利用队列调度组件确定高优先级的数据包,通过链路质量处理选择活动节点,并根据优先级级别将数据包发送到sink。仿真分析表明,与传统方案相比,该机构的效率更高。

A Novel Generative Image Inpainting Model with Dense Gated Convolutional Network 一种基于密集门控卷积网络的生成式图像补绘模型

Damaged image inpainting is one of the hottest research fields in computer image processing. The development of deep learning, especially Convolutional Neural Network (CNN), has significantly enhanced the effect of image inpainting. However, the direct connection between convolution layers may increase the risk of gradient disappearance or overfitting during training process. In addition, pixel artifacts or visual inconsistencies may occur if the damaged area is inpainted directly. To solve the above problems, we propose a novel Dense Gated Convolutional Network (DGCN) for generative image inpainting by modifying the gated convolutional network structure in this paper. Firstly, Holistically-nested edge detector (HED) is utilized to predict the edge information of the missing areas to assist the subsequent inpainting task to reduce the generation of artifacts. Then, dense connections are added to the generative network to reduce the network parameters while reducing the risk of instability in the training process. Finally, the experimental results on CelebA and Places2 datasets show that the proposed model achieves better inpainting results in terms of PSNR, SSIM and visual effects compared with other classical image inpainting models. DGCN has the common advantages of gated convolution and dense connection, which can reduce network parameters and improve the inpainting effect of the network.
损伤图像的修复是计算机图像处理领域的研究热点之一。深度学习,尤其是卷积神经网络(CNN)的发展,极大地增强了图像补图的效果。然而,卷积层之间的直接连接可能会增加训练过程中梯度消失或过拟合的风险。此外,如果直接涂入受损区域,可能会出现像素伪像或视觉不一致。为了解决上述问题,本文通过修改门控卷积网络结构,提出了一种用于生成图像绘制的新型密集门控卷积网络(DGCN)。首先,利用整体嵌套边缘检测器(HED)预测缺失区域的边缘信息,辅助后续的补漆任务,减少伪影的产生;然后,在生成网络中加入密集连接,以减少网络参数,同时降低训练过程中不稳定的风险。最后,在CelebA和Places2数据集上的实验结果表明,与其他经典图像喷漆模型相比,该模型在PSNR、SSIM和视觉效果方面都取得了更好的喷漆效果。DGCN具有门控卷积和密集连接的共同优点,可以减少网络参数,提高网络的涂漆效果。

The development of deep learning, especially Convolutional Neural Network (CNN), has significantly enhanced the effect of image inpainting. However, the direct connection between convolution layers may increase the risk of gradient disappearance or overfitting during training process. In addition, pixel artifacts or visual inconsistencies may occur if the damaged area is inpainted directly. To solve the above problems, we propose a novel Dense Gated Convolutional Network (DGCN) for generative image inpainting by modifying the gated convolutional network structure in this paper. Firstly, Holistically-nested edge detector (HED) is utilized to predict the edge information of the missing areas to assist the subsequent inpainting task to reduce the generation of artifacts. Then, dense connections are added to the generative network to reduce the network parameters while reducing the risk of instability in the training process. Finally, the experimental results on CelebA and Places2 datasets show that the proposed model achieves better inpainting results in terms of PSNR, SSIM and visual effects compared with other classical image inpainting models. DGCN has the common advantages of gated convolution and dense connection, which can reduce network parameters and improve the inpainting effect of the network.\u0000","PeriodicalId":179619,"journal":{"name":"Int.

During the COVID-19 epidemic, the online prescription pattern of Internet healthcare provides guarantee for the patients with chronic diseases and reduces the risk of cross-infection, but it also raises the burden of decision-making for doctors. Online drug recommendation system can effectively assist doctors by analysing the electronic medical records (EMR) of patients. Unlike commercial recommendations, the accuracy of drug recommendations should be very high due to their relevance to patient health. Besides, concept drift may occur in the drug treatment data streams, handling drift and location drift causes is critical to the accuracy and reliability of the recommended results. This paper proposes a multi-model fusion online drug recommendation system based on the association of drug and pathological features with online-nearline-offline architecture. The system transforms drug recommendation into pattern classification and adopts interpretable concept drift detection and adaptive ensemble classification algorithms. We apply the system to the Percutaneous Coronary Intervention (PCI) treatment process. The experiment results show our system performs nearly as good as doctors, the accuracy is close to 100%
在新冠疫情期间,互联网医疗的在线处方模式为慢性病患者提供了保障,降低了交叉感染的风险,但也增加了医生的决策负担。在线药物推荐系统可以通过分析患者的电子病历,有效地辅助医生。与商业推荐不同,药物推荐的准确性应该非常高,因为它们与患者健康相关。此外,药物治疗数据流中可能出现概念漂移,处理漂移和定位漂移原因对推荐结果的准确性和可靠性至关重要。本文提出了一种基于药物与病理特征关联的多模型融合在线推荐系统。该系统将药物推荐转化为模式分类,采用可解释概念漂移检测和自适应集成分类算法。我们将该系统应用于经皮冠状动脉介入治疗(PCI)过程。实验结果表明,该系统的准确率接近100%,接近医生的水平
