The capability to accurately detect web application attacks, especially in a timely fashion, is crucial but remains an ongoing challenge. This study provides an in-depth evaluation of 19 traditional machine learning techniques for detecting web application attacks. The evaluation was conducted across three distinct experiments on refined datasets derived from the HTTPCSIC 2010 dataset. The experiments investigated the performance of these algorithms in different scenarios (e.g., without Knowledge Graph integration, and with KG integration with node2vec feature enhancement). The experimental results revealed that neural network classifiers, notably the Multilayer Perceptron, consistently outperformed other models, achieving accuracy of above 0.90 and maintaining a balanced performance across various metrics. Furthermore, the findings demonstrated that certain algorithms, such as tree-based ensemble methods showed an increase of over 10% in accuracy and Gaussian Process models which exhibited a remarkable improvement in accuracy, rising from 0.84 to 0.99, and in AUC from 0.91 to 1.00, when integrated with the Knowledge Graph, effectively utilizing the additional contextual information. We also found that the KNN classifier demonstrated more than a 16% increase in accuracy. All classifiers showed significant improvements in AUC and other metrics mentioned in our study, indicating that KG integration not only enhances the detection capabilities but also enriches the overall analytical performance of the models. We also observed that linear classifiers and Naive Bayes models generally experienced a decline in performance, highlighting the importance of carefully evaluating the inherent characteristics and capabilities of each algorithm for the web attack detection task.

准确检测网络应用程序攻击的能力至关重要,尤其是及时检测的能力,但这仍是一项持续的挑战。本研究对用于检测网络应用程序攻击的 19 种传统机器学习技术进行了深入评估。评估是在源自 HTTPCSIC 2010 数据集的精炼数据集上通过三个不同的实验进行的。实验研究了这些算法在不同情况下的性能(例如,没有集成知识图谱,以及集成了 KG 并增强了 node2vec 特征)。实验结果表明,神经网络分类器,尤其是多层感知器,始终优于其他模型,准确率达到 0.90 以上,并在各种指标上保持了均衡的性能。此外,研究结果表明,某些算法(如基于树的集合方法)的准确率提高了 10%以上,高斯过程模型的准确率也有显著提高,从 0.84 提高到 0.99,AUC 从 0.91 提高到 1.00。我们还发现,KNN 分类器的准确率提高了 16% 以上。所有分类器的 AUC 和我们研究中提到的其他指标都有明显改善,这表明知识图谱集成不仅增强了检测能力,还丰富了模型的整体分析性能。我们还观察到,线性分类器和 Naive Bayes 模型的性能普遍下降,这凸显了在网络攻击检测任务中仔细评估每种算法固有特征和能力的重要性。

Real-Time Tracking of Basketball Trajectory Based on the Associative MCMC Model 基于关联 MCMC 模型的篮球轨迹实时跟踪

In basketball videos, the trajectories of a basketball changes rapidly. Since the visual features changes in a more homogeneous region, the frame difference method is a suitable basis for trajectory real-time tracking. However, traditional methods need a huge number of iterative calculations in a random image to find spatial feature differences to segment the basketball from to frame, resulting in tracking lag. Therefore, a real-time tracking method of basketball trajectory is designed based on an associative Markov Chain Monte Carlo (MCMC) model. From pixel illumination differences between two adjacent frames in basketball game videos, the basketball’s movement is determined, and the foreground and background of the basketball frame are separated. Then, coordinates of the basketball are detected by a Convolutional Neural Network (CNN), and the change of coordinates is used to construct a visual 2D mapping model, which calculates both angular and linear acceleration of the basketball. To solve the interaction problem of randomness and spatial variability, an associative MCMC model is designed to segment basketball images with simple conditions, and a Bayesian network is established to input parameters of the segmented basketball movement for the determination of trajectory deviation. Finally, basketball movement trends are calculated to achieve real-time tracking of the trajectory in the basketball video. The experimental results show that compared with the original running path, this method has the smallest difference in tracking trajectory error, and the estimation error does not exceed 0.2 when the false alarm rate is 100. The trajectory tracking time is always less than 2.2 seconds, indicating that it has good trajectory tracking ability.

在篮球视频中,篮球的轨迹变化很快。由于视觉特征变化的区域较为均匀,因此帧差法适合作为轨迹实时跟踪的基础。然而,传统方法需要在随机图像中进行大量迭代计算,才能找到空间特征差异,从而分割出每帧的篮球,导致跟踪滞后。因此,本文设计了一种基于关联马尔可夫链蒙特卡洛(MCMC)模型的篮球轨迹实时跟踪方法。根据篮球比赛视频中相邻两帧之间的像素照度差异,确定篮球的运动轨迹,并分离篮球帧的前景和背景。然后,通过卷积神经网络(CNN)检测篮球的坐标,并利用坐标的变化构建视觉二维映射模型,计算篮球的角加速度和线加速度。为了解决随机性和空间可变性的交互问题,设计了一个关联 MCMC 模型来分割条件简单的篮球图像,并建立了一个贝叶斯网络来输入分割后的篮球运动参数,以确定轨迹偏差。最后,计算篮球运动趋势,实现对篮球视频轨迹的实时跟踪。实验结果表明,与原始运行路径相比,该方法跟踪轨迹误差差异最小,误报率为 100 时估计误差不超过 0.2。轨迹跟踪时间始终小于 2.2 秒,表明该方法具有良好的轨迹跟踪能力。

In Vietnam, every year, several competitions for high school students in different disciplines are organized at multilevel, provincial and national, with highly valuable prizes for winners. The problem to be solved by educational managers is how to efficiently select students for their school teams. This study proposed the approach of winner-domain to solving the selection problem by applying two following strategies: (1) students with performance similar to the winners of previous prizes are more likely to win next prizes; (2) the selection of team members is based on the “False Leaving out Better Than False Selecting” rule. This study conceptually defined the winner-domain which is the domain of the performance of winners to select team members. The algorithms forming winner-domain and the process selecting team member were installed. The approach was experimentally applied and evaluated at a high school in Southern Vietnam. The initial achievement showed that the proposed approach outperformed the previous methods which choose team members based on learning or testing outcomes.

In recent years, virtualization platforms have not only been used to integrate data from traditional application systems but have also actively collected Internet of Things (IoT) data from various network transmissions. To address the challenges of real-time monitoring for key metrics on virtualization platforms, this study proposes an optimal machine learning training model that combines semi-supervised Self-Training algorithms with supervised ensemble algorithms. In the application of semi-supervised training learning algorithms, this study utilizes a Self-Training learning algorithm to label a large number of unlabeled virtual machine operational states with a small amount of labeled data, laying the foundation for subsequent model construction. Subsequently, an ensemble learning classification algorithm is introduced to further validate and identify learning models suitable for generalization. Empirical evaluations show that the RandomForest algorithm serves as the optimal base estimator for Self-Training, while the Bagging algorithm is the optimal choice for ensemble learning. The synergy of these two achieves an accuracy exceeding 99%, enabling the model to accurately differentiate between various operational states such as normal operation, resource insufficiency, and faults. Finally, the integrated training model is deployed to a dashboard, displaying the real-time operational status of virtual machines through different colored lights. Simultaneously, operational status information is communicated to stakeholders through various media, further improving coordination, decision-making, and resource allocation issues on the virtualization platform. This study provides an efficient and feasible solution for monitoring and managing virtualization platforms.

近年来,虚拟化平台不仅用于整合传统应用系统的数据,还积极收集来自各种网络传输的物联网(IoT)数据。为解决虚拟化平台关键指标实时监控的难题,本研究提出了一种半监督自训练算法与监督集合算法相结合的最优机器学习训练模型。在半监督训练学习算法的应用中,本研究利用自训练学习算法,以少量标记数据标记大量未标记的虚拟机运行状态,为后续模型构建奠定基础。随后,引入集合学习分类算法,进一步验证和识别适合泛化的学习模型。经验评估表明,RandomForest 算法是自我训练的最佳基础估计器,而 Bagging 算法则是集合学习的最佳选择。这两种算法的协同作用使模型的准确率超过 99%,能够准确区分正常运行、资源不足和故障等各种运行状态。最后,将集成训练模型部署到仪表板上,通过不同颜色的指示灯显示虚拟机的实时运行状态。同时,运行状态信息通过各种媒体传达给利益相关者,进一步改善虚拟化平台上的协调、决策和资源分配问题。这项研究为监控和管理虚拟化平台提供了一个高效可行的解决方案。

To solve the problems of poor estimation of full-body shape and inaccurate capture results in human motion capture in mobile sensor networks, a method of capturing image features of human full-body motion posture in mobile sensor networks is studied. The method uses Markov random fields to cooperate with sensors to extract human full-body motion foreground images and combines guided filtering to enhance the extraction effect of foreground images. Based on the foreground images, a human tree-structured model is established to simulate the actions of human movements. The extracted foreground images are used as input to the convolutional neural network to extract edge features and spatio-temporal features of human motion posture. After fusion, a human motion posture feature matrix is constructed. Based on the least squares method, a strong regression mapping model is constructed. According to the structure of the human tree model, multi-dimensional iterative mapping is performed from top to bottom between the human motion posture feature matrix and the human tree model. The joint positions corresponding to the human motion posture feature matrix in the human tree model are calculated, and the two-dimensional position information of all joint points of the moving human body is obtained. The capture of human full-body motion posture in mobile networks is completed. Experimental data show that the method has clear foreground image extraction, can effectively obtain human motion features, and has accurate capture results of human full-body motion posture.

Customized healthcare for cattle health monitoring is essential, which aims to optimize individual animal health, thereby enhancing productivity, minimizing illness-related risks, and improving overall welfare. Tailoring healthcare practices to individual requirements guarantees that individual animals receive proper attention and intervention, resulting in better health outcomes and sustainable cattle farming practices. In this regard, the manuscript proposes a visual cues-based region prediction methodology to design a customized cattle healthcare system. The proposed automated AI healthcare system uses resource-efficient deep learning-inspired architecture for computer vision applications like performing region-wise classification. The classification mechanism can be used further to identify a cattle and the regions it belongs. Extensive experimentation has been conducted on a redesigned image dataset to identify the best-suited deep-learning framework to perform region classification for livestock, such as cattle. MobileNetV2 outperforms the considered state-of-the-art frameworks by achieving an accuracy of 93% in identifying the regions of the cattle.

With the rapid development of virtual reality (VR) technology, the design and presentation of museum exhibitions are also undergoing changes. However, traditional VR technology has some limitations in terms of transmission speed and user experience, so new technologies need to be introduced to improve these issues. This study focuses on the perspective of optical communication to improve the problems existing in traditional VR technology. A wireless sensor network-based optical communication system is proposed, which utilizes fiber optic transmission to provide stable and high-speed data transmission. Using optical fiber as a transmission medium can effectively transmit a large amount of data with lower transmission delay and higher bandwidth, overcoming the problems of delay and lag caused by low data transmission speed in traditional VR technology. By utilizing the characteristics of optical communication, sensor nodes and VR devices are wirelessly connected. The sensor nodes are arranged in different areas of the museum and connected to the central server through fiber optics. VR devices establish wireless connections with sensor nodes, transmit data through optical signals, achieve high-speed data transmission, and provide more freedom of mobility and a more realistic interactive experience.
