Social Internet of Things (SIoT) is a new model that has integrated into two technologies, Internet of Things (IoT) and Social Networks. The SIoT defines as a social network of objects that are not only smarter but also socially conscious. The major issues related to IoT are; communication between the objects, service composition and service discovery. To address the after-mentioned needs, this paper proposes a possible approach named social pal. The social pal collects and provides the information to the IoT, and hence our proposed social network provides glue to allow the human to device interaction. This study leverages the social relationships among the participants (devices and users) in the system for delivering the required services to the users. By using this platform the capability to select and find the devices, discover the services in the IoT paradigm is augmented. Briefly, the main features of social pal are; create an object, define the relationship, find and discover the pairs of objects that can offer services, etc.
社交物联网(Social Internet of Things, SIoT)是一种融合了物联网(Internet of Things, IoT)和社交网络(Social Networks)两种技术的新模式。SIoT将其定义为一个不仅更智能而且具有社会意识的物体的社交网络。与物联网相关的主要问题有:对象之间的通信、服务组合和服务发现。为了解决上述需求,本文提出了一种可能的方法,称为社交伙伴。社交伙伴收集并提供信息给物联网,因此我们提出的社交网络提供了胶水,允许人与设备交互。本研究利用系统中参与者(设备和用户)之间的社会关系为用户提供所需的服务。通过使用该平台,增强了在物联网范式中选择和查找设备、发现服务的能力。简而言之,社交伙伴的主要特征有:创建对象,定义关系,查找和发现可以提供服务的对象对,等等。

In recent years, people’s demand for data analysis and knowledge acquisition from big data is becoming more urgent. Large-scale crowd evacuation also requires a wealth of decision-making knowledge to provide emergency solution guidance. This paper corresponds the crowd size to the granularity of knowledge objects, and proposes a variablegrained knowledge acquisition model for the evolution mechanism of crowd evacuation stability. The rough set matrix calculation model is used to generate the meta-rules. Through the rigorous discretization of the reversible process analysis logic, the meta-rules are automatically simplified into generalized rules with evacuation guiding significance. The explicit knowledge of stability situation in crowd evacuation is discovered. This study provides a scientific decision-making method for timely and accuratejudgment of the crowd stability, rational organization and guidance of safe evacuation, and also provides scientific basis for the prevention of malignant crowding and trampling events with important theoretical and social significance.
近年来,人们对数据分析和从大数据中获取知识的需求越来越迫切。大规模人群疏散也需要丰富的决策知识来提供应急解决指导。本文将人群规模与知识对象的粒度相对应,提出了一种变粒度的知识获取模型来研究人群疏散稳定性的演化机制。采用粗糙集矩阵计算模型生成元规则。通过对可逆过程分析逻辑的严格离散化,将元规则自动简化为具有疏散指导意义的广义规则。发现了人群疏散过程中稳定状态的显式知识。本研究为及时准确判断人群稳定性、合理组织和指导安全疏散提供了科学的决策方法,也为预防恶性拥挤踩踏事件提供了科学依据,具有重要的理论和社会意义。

Quantum Annealing is an algorithm for solving instances of quadratic unconstrained binary optimization (QUBO) that is implemented in hardware utilizing quantum effects to quickly find approximate solutions. However, QUBO can obviously also be solved by any classical optimization technique, for which various implementations exist. The UQ platform provides a unified interface to various means of solving QUBO that allows for a seamless switch between classical and quantum methods while implementing features such as load and user management.

Since the dimension of the measured scattering field is usually much smaller than the dimension of the unknown parameter, this makes the electromagnetic field integral equation ill-conditioned, and the solution of the equation can be obtained using sparse constraint regularization. For this reason, this paper introduced a nonlinear electromagnetic field inverse scattering imaging algorithm under sparse domain, namely: sparse constraints subspace optimization method (SP-SOM) algorithm, the algorithm is used to reconstruct the spatial distribution information of electrical performance parameters of multi-media targets. To use the inexact Newton method, it can be handled that the scattered field equations is reconstructed using the SP-SOM algorithm. The simulation results show that SP-SOM algorithm can effectively reconstruct the spatial distribution information of electrical performance parameters.
由于被测散射场的维数通常远小于未知参数的维数,这使得电磁场积分方程是病态的,可以使用稀疏约束正则化方法得到方程的解。为此,本文引入了一种稀疏域下的非线性电磁场逆散射成像算法,即:稀疏约束子空间优化法(SP-SOM)算法,该算法用于重建多媒体目标电性能参数的空间分布信息。采用不精确牛顿法,可以采用SP-SOM算法对散射场方程进行重构。仿真结果表明,SP-SOM算法可以有效地重构电性能参数的空间分布信息。

Sparse Bayesian learning (SBL) has been a popular method for sparse signal recovery under the standard linear model (SLM). Since SBL involves a matrix inversion in each iteration, the computation complexity is usually very high when applied to problems with large data set. Consequently, an inversefree sparse Bayesian learning (IF-SBL) algorithm has been proposed to achieve lower reconstruction errors than other state-of-the-art fast sparse recovery methods in low signal-to-noise ratio (SNR) scenarios. In practice, many problems can be formulated as a generalized linear model (GLM) where measurements are obtained in a nonlinear way such as image classification and estimation from quantized data. This work develops inverse-free generalized sparse Bayesian learning (IF-Gr-SBL), which can be viewed as performing iterations between two modules, where one module performs the standard IF-SBL algorithm, the other module performs the minimum mean squared error (MMSE) estimation. Finally, numerical experiments show the effectiveness
由于SBL在每次迭代中都涉及到矩阵的反演,因此在处理大数据集问题时,计算复杂度通常非常高。因此,在低信噪比(SNR)情况下,提出了一种无逆稀疏贝叶斯学习(IF-SBL)算法,以实现比其他最先进的快速稀疏恢复方法更低的重建误差。在实践中,许多问题都可以用广义线性模型(GLM)来表述,其中测量值以非线性的方式获得,例如图像分类和从量化数据中估计。这项工作开发了无逆广义稀疏贝叶斯学习(IF-Gr-SBL),它可以被视为在两个模块之间执行迭代,其中一个模块执行标准IF-SBL算法,另一个模块执行最小均方误差(MMSE)估计。最后,通过数值实验验证了该方法的有效性

Due to the increasing complexity of power grid, SGCC hopes to have a computer-aided decision-making scheme for ICT system fault identification. This paper proposes an ICT fault analysis technology which integrates text classification and image recognition. It aims to solve the problem that only relying on the knowledge reserve and personal experience of a single staff member is often unable to analyze and judge the fault of power grid system. In this paper, the main work is as follows: first, preprocess the ICT fault report data to get more easily recognized structured data by computer; second, build a text recognition model to classify the text content; then build an image recognition model to classify the image content; finally, integrating the text and image classification based on the above content, linear regression is applied to the weight parameters to improve the accuracy and reliability of the classification results. According to the test results of comprehensive test data, the accuracy of the method is good and it can be used as a reliable scheme test.

Autonomous vehicle technology will make possibility of significant benefits to social welfare such as reducing traffic casualties, assisting the mobility of the elderly, and reducing the burden of driving. Among them, collision prediction and avoidance system are especially important topics in real road scenes. In order to realize a collision avoidance system, it is necessary to accurately grasp the surrounding environment of the self-location and predict the behavior of the target. Camera information or Light Detection and Ranging (LiDAR) information are used for behavior prediction. However, LiDAR is impractical due to its high cost. For camera information, the accuracy is lower than that of LiDAR, however there is a possibility that the accuracy can be compensated by introducing machine learning that has been developing in recent years. In this study, we investigate the usefulness of 3D box estimation in behavior prediction using camera information. In 3D box estimation, the dimensions and orientation of the target in the 2D box are regressed using a CNN model. We use MultiBin loss when we regress orientation. And we estimate final 3Dbox parameters based on regression values. Finally, we predict the trajectory using the center of the box and four vertices as inputs, and we verify its usefulness.
自动驾驶汽车技术将使减少交通事故伤亡、帮助老年人的行动、减轻驾驶负担等对社会福利产生重大效益成为可能。其中,碰撞预测与避碰系统在真实道路场景中尤为重要。为了实现避碰系统的自动定位,需要准确地掌握周围环境并预测目标的行为。相机信息或光探测和测距(LiDAR)信息用于行为预测。然而,激光雷达由于其高成本而不切实际。对于相机信息,精度低于LiDAR,但有可能通过引入近年来发展起来的机器学习来补偿精度。在这项研究中,我们研究了三维盒估计在使用相机信息进行行为预测中的有用性。在三维盒估计中,使用CNN模型对目标在二维盒中的尺寸和方向进行回归。当我们回归方向时,我们使用MultiBin损耗。并根据回归值估计出最终的3Dbox参数。最后,我们使用框的中心和四个顶点作为输入来预测轨迹,并验证其有效性。

This paper explores the role of digital platforms and their potential future developments. It makes three contributions. First, the concept of digital platform ecosystem is introduced instead of platform economy. The development of digital platforms depends on a number of political and social factors in addition to economic and technological drivers. Particularly, the role of governance and institutions is emphasized for structuring platform ecosystems. Second, the future of digital platform ecosystems is explored on the basis of scenario planning. This approach allows to consider alternative future trajectories rather than rely on extrapolation of current trends. Last but not least, paper discusses different scenarios developed by international and national organizations which highlight potential futures for digital platform ecosystems.
本文探讨了数字平台的作用及其潜在的未来发展。它有三个贡献。首先,引入数字平台生态系统的概念,取代平台经济。除了经济和技术驱动因素外,数字平台的发展还取决于许多政治和社会因素。特别强调了治理和制度在构建平台生态系统中的作用。其次,在情景规划的基础上探索数字平台生态系统的未来。这种方法允许考虑备选的未来轨迹,而不是依赖于当前趋势的外推。最后但并非最不重要的是,本文讨论了国际和国家组织开发的不同场景,这些场景突出了数字平台生态系统的潜在未来。

It makes three contributions. First, the concept of digital platform ecosystem is introduced instead of platform economy. The development of digital platforms depends on a number of political and social factors in addition to economic and technological drivers. Particularly, the role of governance and institutions is emphasized for structuring platform ecosystems. Second, the future of digital platform ecosystems is explored on the basis of scenario planning. This approach allows to consider alternative future trajectories rather than rely on extrapolation of current trends. Last but not least, paper discusses different scenarios developed by international and national organizations which highlight potential futures for digital platform ecosystems.","PeriodicalId":105556,"journal":{"name":"2020 5th International Conference on Computer and Communication Systems (ICCCS)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114531418","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}
