Autonomous and AI-enabled systems present a challenge for integration within the System of Sys-tems (SoS) paradigm. A full system of systems (SoS) testbed is necessary to verify the integrity of a given system and preserve the modularization and accountability of its constituent systems. This integrated system needs to support iterative, continuous testing and development. This need war-rants the development of a virtual environment that provides the ground truth in a simulated sce-nario, interfaces with real-world data, and uses various domain-specific and domain-agnostic simulation systems for development, testing, and evaluation. These required features present a non-trivial challenge wherein constructive models and systems at different levels of fidelity need to interoperate to advance the testing, evaluation, and integration of complex systems. Such a virtual and constructive SoS architecture should be independent of the underlying computational infra-structure but must be cloud-enabled for wider integration of AI-enabled software components. This paper will present a modular Simulation, Experimentation, Analytics, and Test (SEAT) Lay-ered Architecture Framework, a 10-step methodology. This paper will also demonstrate a case study of a hybrid cloud-enabled simulation SoS that allows extensibility, composability, and de-ployability in different target environments.
自主和人工智能支持的系统对系统-系统(SoS)范式中的集成提出了挑战。一个完整的系统的系统(so)测试平台是必要的,以验证给定系统的完整性,并保持其组成系统的模块化和责任。这个集成系统需要支持迭代的、持续的测试和开发。这需要开发一个虚拟环境,在模拟场景中提供真实情况,与现实世界数据接口,并使用各种特定领域和不可知领域的仿真系统进行开发、测试和评估。这些必需的特性提出了一个重要的挑战,其中不同保真度级别的建设性模型和系统需要互操作,以推进复杂系统的测试、评估和集成。这种虚拟和建设性的SoS架构应该独立于底层计算基础设施,但必须支持云,以便更广泛地集成支持人工智能的软件组件。本文将介绍一个模块化的模拟、实验、分析和测试(SEAT)分层架构框架,一个10步的方法。本文还将演示一个支持混合云的模拟so的案例研究,该模拟so允许在不同的目标环境中具有可扩展性、可组合性和可部署性。

The musical key serves as a crucial element in a piece, offering vital insights into the tonal center, harmonic structure, and chord progressions while enabling tasks such as transposition and arrangement. Moreover, accurate key estimation finds practical applications in music recommendation systems and automatic music transcription, making it relevant across academic and industrial domains. This paper presents a comprehensive comparison between standard deep learning architectures and emerging vision transformers, leveraging their success in various domains. We evaluate their performance on a specific subset of the GTZAN dataset, analyzing six different deep learning models. Our results demonstrate that DenseNet, a conventional deep learning architecture, achieves remarkable accuracy of 91.64%, outperforming vision transformers. However, we delve deeper into the analysis to shed light on the temporal characteristics of each deep learning model. Notably, the vision transformer and SWIN transformer exhibit a slight decrease in overall performance (1.82% and 2.29%, respectively), yet they demonstrate superior performance in temporal metrics compared to the DenseNet architecture. The significance of our findings lies in their contribution to the field of musical key estimation, where accurate and efficient algorithms play a pivotal role. By examining the strengths and weaknesses of deep learning architectures and vision transformers, we can gain valuable insights for practical implementations, particularly in music recommendation systems and automatic music transcription. Our research provides a foundation for future advancements and encourages further exploration in this area.
音阶是乐曲中至关重要的元素,它提供了对音调中心、和声结构和和弦进行的重要见解,同时也实现了诸如换位和编曲等任务。此外,准确的键估计在音乐推荐系统和自动音乐转录中找到了实际应用,使其在学术和工业领域都具有相关性。本文介绍了标准深度学习架构和新兴视觉转换器之间的全面比较,利用它们在各个领域的成功。我们在GTZAN数据集的特定子集上评估了它们的性能,分析了六种不同的深度学习模型。我们的研究结果表明,传统深度学习架构DenseNet的准确率达到了91.64%,优于视觉变压器。然而,我们更深入地分析了每个深度学习模型的时间特征。值得注意的是,视觉变压器和SWIN变压器的整体性能略有下降(分别为1.82%和2.29%),但与DenseNet架构相比,它们在时间指标上表现出优越的性能。我们的发现的意义在于它们对音乐键估计领域的贡献,其中准确和高效的算法起着关键作用。通过研究深度学习架构和视觉转换器的优缺点,我们可以为实际实现获得有价值的见解,特别是在音乐推荐系统和自动音乐转录方面。我们的研究为未来的发展奠定了基础,并鼓励了该领域的进一步探索。

Nowadays, Augmented Reality flourishes in educational settings. Yet, little is known about teachers’ and children’s views of Augmented Reality applications in Preschool. This paper explores 71 preschoolers’ opinions of Augmented Reality teaching integrated into a traditional learning activity. Additionally, five educators’ views of Augmented Reality applications in Preschool are captured. Mixed methods with questionnaires and semi-structured interviews were used. The questionnaires record children’s preferences regarding their favorite learning activity between traditional and the Augmented Reality one. Additionally, they explore the activity preschoolers would like to repeat and found most enjoyable: playful. Regarding quantitative data analysis, independent/paired samples t-tests and chi-square test along with bootstrapping with 1000 samples were used. As for the qualitative data collection, educators’ semi-structured interviews focused on three axes: (a) children’s motivation and engagement in Augmented Reality activities, (b) Augmented Reality’s potential to promote skills, and (c) Augmented Reality as a teaching tool in preschool. The emerging results are: Preschoolers prefer more Augmented Reality activities than traditional ones. There are no statistically significant gender differences in preferences for Augmented Reality activities. Educators regard Augmented Reality technology as an innovative, beneficial teaching approach in preschool. However, they express concern regarding the promotion of collaboration among preschoolers via Augmented Reality.
如今,增强现实在教育环境中蓬勃发展。然而,教师和儿童对增强现实在学前教育中的应用的看法却知之甚少。本文调查了71名学龄前儿童对将增强现实教学融入传统学习活动的看法。此外,本文还收集了五位教育工作者对增强现实在学前教育中的应用的看法。采用问卷调查和半结构化访谈的混合方法。问卷记录了孩子们对传统学习活动和增强现实学习活动的偏好。此外,他们探索学龄前儿童喜欢重复的活动,并发现最有趣的:好玩。在定量数据分析方面,采用独立/配对样本t检验和卡方检验以及1000样本的bootstrapping。在定性数据收集方面,教育者的半结构化访谈集中在三个方面:(a)儿童在增强现实活动中的动机和参与度,(b)增强现实提升技能的潜力,以及(c)增强现实作为学前教育的教学工具。新出现的结果是:学龄前儿童比传统活动更喜欢增强现实活动。在对增强现实活动的偏好上,没有统计学上显著的性别差异。教育工作者认为增强现实技术是一种创新的、有益的学前教育教学方法。然而,他们对通过增强现实促进学龄前儿童之间的合作表示关注。

In this paper, we present a new egocentric metaphor for graph visualization that consists in positioning a graph between two concentric spheres of different radii. It improves the expansion of nodes in space, contrary to 3D spatialization algorithms. The edge drawing is optimized by pushing all the edges into the area delimited by our two concentric spheres so that a user can move freely without being encumbered by edges. Our new metaphor also makes it possible to reduce the display angles in order to have a global view of the graph without leaving the egocentricity.
在本文中,我们提出了一种新的图形可视化的自我中心隐喻,它包括将一个图形定位在两个不同半径的同心球体之间。与3D空间化算法相反,它改善了节点在空间中的扩展。通过将所有边缘推入我们的两个同心球体划定的区域来优化边缘绘制,以便用户可以自由移动而不受边缘的阻碍。我们的新隐喻也可以减少显示角度,以便在不离开自我中心的情况下拥有图形的全局视图。

An Agent-Based Simulation Platform for a Safe Election: From Design to Simulation 基于agent的安全选举仿真平台:从设计到仿真

Managing the logistics and safety of an election system, from delivering voting machines to the right locations at the right time to ensuring that voting lines remain reasonable in length is a complex problem due to the scarcity of resources, especially human poll workers, and the impact of human behavior and disrupting events on the performance of this critical system. These complexities grew with the need for physical distancing during the COVID-19 pandemic coinciding with multiple key national elections, including the 2020 general presidential election in the USA. In this paper, we propose a digital clone platform leveraging agent-based simulation to model and experiment with resource allocation decisions and voter turnout fluctuations and facilitate “what-if” scenario testing of any election. As a use case, we consider three different concurrent polling location problems, namely, resource allocation, polling layout, and management. The main aim is to reduce voter waiting time and provide visibility of different scenarios for polling and state-level managers. We explain the proposed simulation platform based on Fulton County for the 2020 presidential US election. Fulton County had 238 polling locations in 2020, which provided publicly available voter turnout data. The developed platform realistically models at the county level and at specific locations, suggesting the possible allocation of finite resources among locations in the county and the configuration of each location, accounting for physical, legal, and technical constraints. Multiple realistic scenarios were developed and embedded into the simulation platform to evaluate and verify the different systems. The system performance and key attributes of the election system, such as waiting time, resource utilization, and layout safety, were tested and validated.
管理选举系统的后勤和安全,从在正确的时间将投票机运送到正确的地点,到确保投票队伍保持合理的长度,是一个复杂的问题,因为资源稀缺,特别是人类投票工作人员,以及人类行为和干扰事件对这一关键系统性能的影响。在2019冠状病毒病大流行期间,包括2020年美国总统大选在内的多个关键全国选举期间,需要保持身体距离,这些复杂性随之增加。在本文中,我们提出了一个数字克隆平台,利用基于智能体的模拟对资源分配决策和选民投票率波动进行建模和实验,并促进对任何选举的“假设”场景进行测试。作为一个用例,我们考虑三个不同的并发轮询位置问题,即资源分配、轮询布局和管理。主要目的是减少选民等待时间,并为投票和州级管理人员提供不同场景的可见性。我们解释了基于富尔顿县的2020年美国总统大选的拟议模拟平台。2020年,富尔顿县有238个投票站,提供了公开的选民投票率数据。开发的平台实际地在县一级和特定地点进行建模,建议在县的各个地点之间分配有限资源和每个地点的配置,考虑到物理、法律和技术限制。开发了多个现实场景并将其嵌入到仿真平台中,以评估和验证不同的系统。对系统性能和选举系统的关键属性如等待时间、资源利用率、布局安全性等进行了测试和验证。

An Instance- and Label-Based Feature Selection Method in Classification Tasks 基于实例和标签的分类任务特征选择方法

Feature selection is crucial in classification tasks as it helps to extract relevant information while reducing redundancy. This paper presents a novel method that considers both instance and label correlation. By employing the least squares method, we calculate the linear relationship between each feature and the target variable, resulting in correlation coefficients. Features with high correlation coefficients are selected. Compared to traditional methods, our approach offers two advantages. Firstly, it effectively selects features highly correlated with the target variable from a large feature set, reducing data dimensionality and improving analysis and modeling efficiency. Secondly, our method considers label correlation between features, enhancing the accuracy of selected features and subsequent model performance. Experimental results on three datasets demonstrate the effectiveness of our method in selecting features with high correlation coefficients, leading to superior model performance. Notably, our approach achieves a minimum accuracy improvement of 3.2% for the advanced classifier, lightGBM, surpassing other feature selection methods. In summary, our proposed method, based on instance and label correlation, presents a suitable solution for classification problems.
特征选择在分类任务中至关重要,因为它有助于提取相关信息,同时减少冗余。本文提出了一种同时考虑实例关联和标签关联的新方法。采用最小二乘法计算各特征与目标变量之间的线性关系,得到相关系数。选择相关系数高的特征。与传统方法相比,我们的方法有两个优点。首先,从大量特征集中有效地选取与目标变量高度相关的特征,降低数据维数,提高分析建模效率;其次,我们的方法考虑了特征之间的标签相关性,提高了所选特征的准确性和后续模型的性能。在三个数据集上的实验结果表明,我们的方法在选择高相关系数的特征方面是有效的,从而获得了更好的模型性能。值得注意的是,我们的方法在高级分类器lightGBM上实现了3.2%的最小精度提高,超过了其他特征选择方法。综上所述,我们提出的基于实例和标签关联的分类方法,为分类问题提供了一个合适的解决方案。

The number of Internet of Things (IoT) devices has increased dramatically in recent years, and Bluetooth technology is critical for communication between IoT devices. It is possible to protect electronic communications, the Internet of Things (IoT), and big data from malware and data theft with BlueZ’s Bluetooth File Transfer Filter (BTF). It can use a configurable filter to block unauthorized Bluetooth file transfers. The BTF is available for various Linux distributions and can protect many Bluetooth-enabled devices, including smartphones, tablets, laptops, and the Internet of Things. However, the increased number and density of Bluetooth devices have also created a serious problem—the Bluetooth worm. It poses a severe threat to the security of Bluetooth devices. In this paper, we propose a Bluetooth OBEX Proxy (BOP) to filter malicious files transferred to devices via the OBEX system service in BlueZ. The method described in this article prevents illegal Bluetooth file transfers, defending big data, the Internet of Things (IoT), and electronic communications from malware and data theft. It also protects numerous Bluetooth devices, including smartphones, tablets, laptops, and the Internet of Things, with many Linux distributions. Overall, the detection findings were entirely accurate, with zero false positives and 2.29% misses.
近年来,物联网(IoT)设备的数量急剧增加,蓝牙技术对于物联网设备之间的通信至关重要。借助BlueZ的蓝牙文件传输过滤器(BTF),可以保护电子通信、物联网(IoT)和大数据免受恶意软件和数据盗窃。它可以使用一个可配置的过滤器来阻止未经授权的蓝牙文件传输。BTF可用于各种Linux发行版,可以保护许多支持蓝牙的设备,包括智能手机、平板电脑、笔记本电脑和物联网。然而,蓝牙设备数量和密度的增加也带来了一个严重的问题——蓝牙蠕虫。这对蓝牙设备的安全性构成了严重的威胁。在本文中,我们提出了一个蓝牙OBEX代理(BOP)来过滤通过蓝牙OBEX系统服务传输到设备的恶意文件。本文中描述的方法可以防止非法蓝牙文件传输,保护大数据,物联网(IoT)和电子通信免受恶意软件和数据盗窃。它还可以保护许多蓝牙设备,包括智能手机、平板电脑、笔记本电脑和许多Linux发行版的物联网。总的来说,检测结果是完全准确的,零假阳性和2.29%的遗漏。

Knowledge graphs (KGs) are widely used in the education domain to offer learners a semantic representation of domain concepts from educational content and their relations, termed as educational knowledge graphs (EduKGs). Previous studies on EduKGs have incorporated concept extraction and weighting modules. However, these studies face limitations in terms of accuracy and performance. To address these challenges, this work aims to improve the concept extraction and weighting mechanisms by leveraging state-of-the-art word and sentence embedding techniques. Concretely, we enhance the SIFRank keyphrase extraction method by using SqueezeBERT and we propose a concept-weighting strategy based on SBERT. Furthermore, we conduct extensive experiments on different datasets, demonstrating significant improvements over several state-of-the-art keyphrase extraction and concept-weighting techniques.
知识图被广泛应用于教育领域,为学习者提供教育内容及其关系的领域概念的语义表示,称为教育知识图。以往对EduKGs的研究包含了概念提取和权重模块。然而,这些研究在准确性和性能方面面临局限性。为了解决这些挑战,本工作旨在通过利用最先进的词和句子嵌入技术来改进概念提取和加权机制。具体而言,我们利用SqueezeBERT对SIFRank关键词提取方法进行了改进,并提出了一种基于SBERT的概念加权策略。此外,我们在不同的数据集上进行了广泛的实验,证明了几种最先进的关键词提取和概念加权技术的显著改进。

As generative NLP can now produce content nearly indistinguishable from human writing, it is becoming difficult to identify genuine research contributions in academic writing and scientific publications. Moreover, information in machine-generated text can be factually wrong or even entirely fabricated. In this work, we introduce a novel benchmark dataset containing human-written and machine-generated scientific papers from SCIgen, GPT-2, GPT-3, ChatGPT, and Galactica, as well as papers co-created by humans and ChatGPT. We also experiment with several types of classifiers—linguistic-based and transformer-based—for detecting the authorship of scientific text. A strong focus is put on generalization capabilities and explainability to highlight the strengths and weaknesses of these detectors. Our work makes an important step towards creating more robust methods for distinguishing between human-written and machine-generated scientific papers, ultimately ensuring the integrity of scientific literature.
由于生成式NLP现在可以产生与人类写作几乎没有区别的内容,因此在学术写作和科学出版物中识别真正的研究贡献变得越来越困难。此外,机器生成文本中的信息在事实上可能是错误的,甚至完全是捏造的。在这项工作中,我们引入了一个新的基准数据集,其中包含来自SCIgen, GPT-2, GPT-3, ChatGPT和卡拉狄加的人类编写和机器生成的科学论文,以及人类和ChatGPT共同创建的论文。我们还实验了几种类型的分类器——基于语言的和基于转换的——用于检测科学文本的作者身份。重点放在泛化能力和可解释性上,以突出这些检测器的优点和缺点。我们的工作朝着创建更强大的方法来区分人类写作和机器生成的科学论文迈出了重要的一步,最终确保了科学文献的完整性。

Monitoring Key Pair Usage through Distributed Ledgers and One-Time Signatures 通过分布式账本和一次性签名监控密钥对的使用

Private key management is a complex obstacle arising from the traditional public key infrastructure model. However, before any related security breach can be addressed, it must first be reliably detected. Certificate Transparency (CT) is an example of a certificate issuance monitoring strategy, developed to detect the possible malfeasance of certification authorities (CAs). To the best of our knowledge, CT and other detection mechanisms do not cover digitally signed documents made by an end user, which are also susceptible to CA misbehavior. We modify the CT framework to handle signed documents via logging certificates in the blockchain to enable the secure and user-friendly monitoring of one-time signatures, backdating protection, and effective CA misbehavior detection. Moreover, to demonstrate the feasibility of our proposal, we present distinct deployment scenarios and analyze the storage, performance, and monetary costs.
私钥管理是传统公钥基础设施模式带来的复杂障碍。然而,在解决任何相关的安全漏洞之前,必须首先可靠地检测到它。证书透明度(Certificate Transparency, CT)是证书颁发监控策略的一个示例,用于检测证书颁发机构(Certificate authority, ca)可能存在的不当行为。据我们所知,CT和其他检测机制不包括最终用户生成的数字签名文档,这些文档也容易受到CA不当行为的影响。我们修改了CT框架,通过区块链中的日志证书来处理签名的文档,从而实现对一次性签名的安全、用户友好的监控、回溯保护和有效的CA不当行为检测。此外,为了演示我们建议的可行性,我们提出了不同的部署方案,并分析了存储、性能和货币成本。
