Vehicle detection in degraded hazy conditions poses significant challenges in computer vision. It is difficult to detect objects accurately under hazy conditions because vision is reduced, and color and texture information is distorted. This research paper presents a comparative analysis of different YOLO (You Only Look Once) methodologies, including YOLOv5, YOLOv6, and YOLOv7, for object detection in mixed traffic under degraded hazy conditions. The accuracy of object detection algorithms can be significantly impacted by hazy weather, so creating reliable models is critical. An open-source dataset of footage obtained from security cameras installed on traffic signals is used for this study to evaluate the performance of these algorithms. The dataset includes various traffic objects under varying haze levels, providing a diverse range of atmospheric conditions encountered in real-world scenarios. The experiments illustrate that the YOLO-based techniques are effective at detecting objects in degraded hazy conditions and give information about how well they perform in comparison. The findings help object detection models operate more accurately and consistently under adverse weather conditions.
雾霾条件下的车辆检测对计算机视觉提出了重大挑战。在模糊条件下,由于视觉降低,颜色和纹理信息失真,难以准确检测物体。本文对YOLOv5、YOLOv6和YOLOv7三种不同的YOLO (You Only Look Once)方法在混流条件下的目标检测进行了对比分析。雾霾天气会严重影响目标检测算法的准确性,因此建立可靠的模型至关重要。本研究使用从安装在交通信号上的安全摄像头获得的视频的开源数据集来评估这些算法的性能。该数据集包括不同雾霾水平下的各种交通对象,提供了现实场景中遇到的各种大气条件。实验表明,基于yolo的技术可以有效地检测退化雾霾条件下的目标,并给出了它们在比较中表现如何的信息。这些发现有助于目标检测模型在恶劣天气条件下更准确、更一致地运行。

To choose the best forecasting model, it is essential to comprehend time series data since external influences like social, economic, and political events may affect the way the data behave. This study considers outside variables that could have an impact on the target variable used in improving the predictions. India Machinery and Transport Equipment Dataset is gathered from various sources, are cleaned, pre-processed, the missing values are removed, data types are converted, and dependent variables are identified before being used. By incorporating the SARIMAX model with the GARCH model and experimenting with various parameters and conditions, the current study seeks to enhance it. The SARIMAX-GARCH Model is a time series forecasting method used to predict market swings and export values. A helper model is developed to forecast the exogenous value to forecast the export value, which is then used as input for the final model. The ideal parameters for boosting the hybrid model's performance were identified through hyperparameter tuning. The results of this study provide estimates for future export values and contribute to a better understanding of India's Machinery and Transport Equipment export market. This research work focuses on export value forecasting with the use of future exogenous variables. Exogenous factors are essential for predicting market changes and, as a result, support the forecasting of precise export values.
为了选择最好的预测模型,理解时间序列数据是必不可少的,因为外部影响,如社会、经济和政治事件可能会影响数据的行为方式。本研究考虑了可能对用于改进预测的目标变量产生影响的外部变量。印度机械和运输设备数据集从各种来源收集,经过清理,预处理,删除缺失值,转换数据类型,并在使用前识别因变量。通过将SARIMAX模型与GARCH模型相结合,并在不同参数和条件下进行试验,本研究旨在改进SARIMAX模型。SARIMAX-GARCH模型是一种用于预测市场波动和出口价值的时间序列预测方法。开发一个辅助模型来预测外生值以预测出口值,然后将外生值用作最终模型的输入。通过超参数整定,确定了提高混合动力模型性能的理想参数。本研究的结果提供了对未来出口价值的估计,有助于更好地了解印度机械和运输设备出口市场。本研究的重点是利用未来外生变量对出口价值进行预测。外生因素对于预测市场变化是至关重要的,因此也有助于准确预测出口价值。

High-quality data might be difficult to be produced when there is a large quantity of information in a single educational dataset. Researchers in the field of educational data mining have recently begun to rely more and more on data mining methodologies in their investigations. However, instead of undertaking feature selection methods, many research investigations have focused on picking appropriate learning algorithms. Since these datasets are computationally complicated, they need a lot of computing time for categorization. This article examines the use of wrapper approaches for the purpose of managing high-dimensional datasets in order to pick appropriate features for a machine learning approach. This study then suggests a strategy for improving the quality of student or educational datasets. For future investigations, the suggested framework that utilizes filter and wrapper-based approaches may be used for many medical and industrial datasets.
当单个教育数据集中存在大量信息时,可能难以产生高质量的数据。近年来,教育数据挖掘领域的研究人员开始越来越多地依赖于数据挖掘方法。然而,许多研究都集中在选择合适的学习算法上,而不是采用特征选择方法。由于这些数据集计算复杂,它们需要大量的计算时间进行分类。本文探讨了如何使用包装器方法来管理高维数据集,以便为机器学习方法选择合适的特性。然后,本研究提出了提高学生或教育数据集质量的策略。对于未来的研究,建议的使用过滤器和包装为基础的方法的框架可用于许多医疗和工业数据集。

Pub Date : 2022-09-15 DOI: 10.36548/jucct.2022.3.004

Everyone has their own distinct musical preferences; it's safe to assume that each music will find an appreciative audience. It's important to note that there isn't a single human society that has ever survived without music. There are two major gains from this study. Initially, a multi-strategy approach is taken to develop hybrid recommendation algorithms that give more accuracy than the existing algorithms. Also this hybrid algorithm is used to find new music in real time. This allows the algorithm to make an educated guess as to which musician and song best suit the user. As a second step, a general context-aware and emotion-based customized music framework is offered to facilitate the quick growth of context-aware music recommendation systems and to shed light on the whole recommendation procedure. Multiple methods exist for responding to requests, and a general framework is required for both collecting these methods and interpreting them within the context of the proposed framework. The kind of recommendation algorithm used is decided by the format of the input.
每个人都有自己独特的音乐偏好;可以肯定的是,每首音乐都会找到一个欣赏的听众。值得注意的是,没有一个人类社会可以在没有音乐的情况下生存。这项研究有两个主要收获。首先,采用多策略方法开发混合推荐算法,使其比现有算法具有更高的准确率。该混合算法还可用于实时发现新音乐。这使得该算法能够做出有根据的猜测,哪位音乐家和哪首歌最适合用户。第二步,提供了一个通用的基于上下文感知和情感的定制音乐框架,以促进上下文感知音乐推荐系统的快速发展,并阐明了整个推荐过程。存在用于响应请求的多种方法,并且需要一个通用框架来收集这些方法并在提议的框架的上下文中解释它们。使用哪种推荐算法取决于输入的格式。

Known for excellent convenience and abundant facilities, smart cities offer CCTV, delivery robots, security robots, and so on to its residents. Along with the collaboration of IoT (Internet Of Things), the innovation of smart city has gained immense attraction at present. Besides, the risks and challenging in the field of telecommunication still persists as the implemented wireless networks results in traffic and anomaly behaviour. Such issues become critical in case of large-scale infrastructure networks like WSN’s. As such circumstances, to perform efficient health and environment monitoring, the need for a next generation networked system raises. As the traditional anomaly detection schemes doesn’t work out for delay-sensitive environments due to increased latency, we propose a scalable, hybrid spatiotemporal anomaly detection approach that can effectively detect potential anomalies in the network. With the use of real-time stream processing, and other methodologies like Software-Defined Networking (SDN), a Fog Computing-based 5G low-power Wide Area Network (LPWAN) solution is developed and tested on a Antwerp’s City of Things testbed. The proposed approach is found to be beneficial when deployed in a real network environment with nearly 1800 sensor nodes.
智慧城市以其优越的便利性和丰富的设施而闻名,为其居民提供闭路电视,送货机器人,保安机器人等。随着物联网(IoT)的协同发展,智慧城市的创新在当前获得了巨大的吸引力。此外,由于实现的无线网络导致流量和异常行为,电信领域的风险和挑战仍然存在。在WSN这样的大型基础设施网络中,这些问题变得至关重要。在这种情况下,为了执行有效的健康和环境监测,对下一代网络系统的需求增加了。针对传统的异常检测方案在延迟敏感环境下由于延迟增加而无法正常工作的问题,我们提出了一种可扩展的混合时空异常检测方法,可以有效地检测网络中的潜在异常。通过使用实时流处理和软件定义网络(SDN)等其他方法,开发了基于雾计算的5G低功耗广域网(LPWAN)解决方案,并在安特卫普的物联网城市测试台上进行了测试。在实际的网络环境中部署了近1800个传感器节点,结果表明该方法是有效的。

This study offers a comprehensive analysis of the conversational tool known as chatbots, which emerged in the contemporary era. This paper also discusses how this tool is expanding its root in the life of human beings as well as the pros-cons that will be generated by the chatbots.","PeriodicalId":443052,"journal":{"name":"Journal of Ubiquitous Computing and Communication Technologies","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134388495","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}

The detection and resolution of any crime is made possible with the use of modern technology. The crime is discovered, the suspect is named, and then the court is presented with sufficient proof to show that the crime was committed by the named suspect. The proofs could be mental or physical. The best lie detector now in existence, according to this invention, is reported to be able to catch even sneaky crooks who successfully pass the standard polygraph test. Criminal investigators gather physical evidence, which can be destroyed, while mental evidence is preserved in the brain and cannot be erased. The brain wave reaction of an individual to crime-related images or phrases displayed on a computer screen can be used to analyze those evidences, using Electroencephalography (EEG). This novel Brain Fingerprinting technique uses brainwaves, which can be used to determine if the test participant remembers the specifics of the incident. The brain wave issuer will trap him even if they are consciously hiding the required information. Over 120 studies, including testing on Federal agents, testing for the United States intelligence agency and the US Navy, tests on actual cases, including felony crimes, have demonstrated that brain fingerprinting is 100 percent accurate.
现代科技的运用使侦查和解决任何犯罪成为可能。犯罪被发现,嫌疑人被点名,然后法院有足够的证据表明犯罪是由点名的嫌疑人实施的。证据可以是精神上的也可以是身体上的。据报道,根据这项发明,目前最好的测谎仪甚至可以抓住那些成功通过标准测谎仪测试的狡猾的骗子。刑事调查人员收集可以被销毁的物证,而精神证据则保存在大脑中,不能被抹去。一个人对电脑屏幕上显示的与犯罪有关的图像或短语的脑电波反应可以用脑电图(EEG)来分析这些证据。这种新颖的脑指纹技术使用脑电波,可以用来确定测试参与者是否记得事件的细节。即使他们有意识地隐藏所需的信息,脑电波发出者也会诱骗他。超过120项研究,包括对联邦特工的测试,对美国情报机构和美国海军的测试,对包括重罪在内的实际案件的测试,都证明了大脑指纹识别是100%准确的。
