—As network attacks are more and more frequent and network security is more and more serious, it is important to detect network intrusion accurately and efficiently. With the continuous development of deep learning, a lot of research achievements are applied to intrusion detection. Deep learning is more accurate than machine learning, but in the face of a large amount of data learning, the performance will be degraded due to data imbalance. In view of the serious imbalance of network traffic data sets at present, this paper proposes to process data expansion with GAN to solve data imbalance and detect network intrusion in combination with CNN and BiLSTM. In order to verify the efficiency of the model, the CIC-IDS 2017 data set is used for evaluation, and the model is compared with machine learning methods such as Random Forest and Decision Tree. The experiment shows that the performance of this model is significantly improved over other traditional models, and the GAN-CNN-BiLSTM model can improve the efficiency of intrusion detection, and its overall accuracy is improved compared with SVM, DBN, CNN, BiLSTM and other models.
随着网络攻击越来越频繁,网络安全问题越来越严重,准确、高效地检测网络入侵变得越来越重要。随着深度学习的不断发展,大量的研究成果被应用到入侵检测中。深度学习比机器学习更准确,但面对大量的数据学习,会因为数据不平衡而导致性能下降。针对目前网络流量数据集失衡严重的问题,本文提出结合CNN和BiLSTM,用GAN处理数据扩展来解决数据失衡,检测网络入侵。为了验证模型的有效性,使用CIC-IDS 2017数据集进行评估,并将模型与随机森林、决策树等机器学习方法进行比较。实验表明,该模型的性能比其他传统模型有了明显的提高,GAN-CNN-BiLSTM模型可以提高入侵检测的效率,与SVM、DBN、CNN、BiLSTM等模型相比,其整体精度得到了提高。

—Removing as much noise as possible in an image while preserving its fine details is a complex and challenging task. We propose a wavelet-based and non-local means (NLM) denoising method to overcome the problem. Two well-known wavelets: dual-tree complex wavelet transform (DT-CWT) and discrete wavelet transform (DWT), have been used to change the noise image into several wavelet coefficients sequentially. NLM filtering and universal hard thresholding with cycle spinning have been used for thresholding on its approximation and detail coefficients, respectively. The inverse two-dimensional DWT was applied to the modified wavelet coefficients to obtain the denoised image. We conducted experiments with twelve test images on the set12 data set, adding the additive Gaussian white noise with variances of 10 to 90 in increments of 10. Three evaluation metrics, such as peak signal noise to rate (PSNR), structural similarity index metric (SSIM), and mean square error (MSE), have been used to evaluate the effectiveness of the proposed denoising method. From these measurement results, the proposed denoising method outperforms DT-CWT, DWT, and NLM almost in all noise levels except for the noise level of 10. At that noise level, the proposed denoising method is lower than NLM but better than DT-CWT and DWT.
-在保留图像细节的同时尽可能多地去除图像中的噪点是一项复杂而具有挑战性的任务。我们提出了一种基于小波的非局部均值去噪方法来克服这一问题。利用双树复小波变换(DT-CWT)和离散小波变换(DWT)将噪声图像依次变换成多个小波系数。分别采用NLM滤波和循环纺丝通用硬阈值法对其逼近系数和细节系数进行阈值设定。对修改后的小波系数进行逆二维小波变换,得到去噪后的图像。我们在set12数据集上使用12张测试图像进行实验,以10为增量加入方差为10 ~ 90的加性高斯白噪声。采用峰值信噪比(PSNR)、结构相似度指标(SSIM)和均方误差(MSE)三个评价指标来评价所提出的去噪方法的有效性。从这些测量结果来看,除了噪声级别为10之外,所提出的去噪方法几乎在所有噪声级别上都优于DT-CWT、DWT和NLM。在该噪声水平下,该方法的去噪效果低于NLM,但优于DT-CWT和DWT。

—In recent decades, cardiovascular diseases have eclipsed all others as the main reason for death in both low and middle income countries. Early identification and continuous clinical monitoring can reduce the death rate associated with heart disorders. Neither service is yet accessible, as it requires more intellect, time, and skill to effectively detect cardiac disorders in all circumstances and to advise a patient for 24 hours. In this study, researchers suggested a Machine Learning-based approach to forecast the development of cardiac disease. For precise identification of cardiac disease, an efficient ML technique is required. The proposed method works on five classes, one normal and four diseases. In the research, all classes were assigned a primary task, and recommendations were made based on that. The proposed method optimises feature weighting and selects efficient features. Following feature optimization, adaptive boost learning using tree and KNN bases is used. In the trial, sensitivity improved by 3-4%, specificity by 4-5%, and accuracy by 3-4% compared to the previous approach.
近几十年来,在低收入和中等收入国家,心血管疾病已超过所有其他疾病,成为导致死亡的主要原因。早期识别和持续的临床监测可以降低与心脏疾病相关的死亡率。这两项服务目前都还无法实现,因为它需要更多的智力、时间和技能,才能在所有情况下有效地检测心脏疾病,并在24小时内为患者提供建议。在这项研究中,研究人员提出了一种基于机器学习的方法来预测心脏病的发展。为了准确识别心脏疾病,需要一种高效的ML技术。该方法适用于五类一常四病。在研究中,每个班级都被分配了一个主要任务,并在此基础上提出建议。该方法优化特征权重,选择有效特征。在特征优化之后,使用树基和KNN基进行自适应增强学习。在试验中,与以前的方法相比,敏感性提高了3-4%,特异性提高了4-5%,准确性提高了3-4%。

The rising number of automobiles has led to an increased demand for a reliable license plate identification system that can perform effectively in diverse conditions. This applies to local authorities, public organizations, and private companies in Morocco, as well as worldwide. To meet this need, a strong License Plate Recognition (LPR) system is required, taking into account local plate specifications and fonts used by plate manufacturers. This paper presents an intelligent LPR system based on the YOLOv5 framework, trained on a customized dataset encompassing multiple fonts and circumstances such as illumination, climate, and lighting. The system incorporates an intelligent region segmentation level that adapts to the plate's type, improving recognition accuracy and addressing separator issues. Remarkably, the model achieves an impressive precision rate of 99.16% on problematic plates with specific illumination, separators, and degradations. This research represents a significant advancement in the field of license plate recognition, providing a reliable solution for accurate identification and paving the way for broader applications in Morocco and beyond. Keywords—License plate recognition; YOLOv5; intelligent region segmentation; customized dataset; Moroccan license plate issues; fonts-based data

—Anomalous trajectory detection is an important approach to detecting taxi fraud behaviors in urban traffic systems. The existing methods usually ignore the integration of the trajectory access location with the time and trajectory structure, which incorrectly detects normal trajectories that bypass the congested road as anomalies and ignores circuitous travel of trajectories. Therefore, this study proposes an anomalous trajectory detection algorithm using the popular routes in different traffic periods to solve this problem. First, to obtain popular routes in different time periods, this study divides the time according to the time distribution of the traffic trajectories. Second, the spatiotemporal frequency values of the nodes are obtained by combining the trajectory point moments and time span to exclude the interference of the temporal anomaly trajectory on the frequency. Finally, a gridded distance measurement method is designed to quantitatively measure the anomaly between the trajectory and the popular routes by combining the trajectory position and trajectory structure. Extensive experiments are conducted on real taxi trajectory datasets; the results show that the proposed method can effectively detect anomalous trajectories. Compared to the baseline algorithms, the proposed algorithm has a shorter running time and a significant improvement in F-Score , with the highest improvement rate of 7.9%, 5.6%, and 10.7%, respectively.
——异常轨迹检测是城市交通系统中出租车欺诈行为检测的重要手段。现有的方法通常忽略了轨迹进入位置与时间和轨迹结构的整合,错误地将绕过拥堵道路的正常轨迹视为异常,忽略了轨迹的绕行。因此,本研究提出了一种利用不同交通时段热门路线的异常轨迹检测算法来解决这一问题。首先,根据交通轨迹的时间分布进行时间划分,得到不同时段的热门路线。其次,结合轨迹点矩和时间跨度得到节点的时空频率值,排除时间异常轨迹对频率的干扰;最后,设计了一种网格距离测量方法,结合轨迹位置和轨迹结构,定量测量轨迹与常用路线之间的异常。在真实滑行轨迹数据集上进行了大量实验;结果表明,该方法能有效地检测出异常轨迹。与基线算法相比,本文算法的运行时间更短,F-Score也有显著提升,最高提升率分别为7.9%、5.6%和10.7%。

—With the development of virtual technology, posture recognition technology has been integrated into virtual technology. This new technology allows users to further understand and observe the activities carried out in life scenes based on their original observation of the external world. And it enables them to make intelligent decisions. Existing posture recognition cannot meet the requirements of precise positioning in virtual environments. Therefore, a two-stage three-dimensional pose recognition model is proposed. The experiment illustrates that the three-dimensional gesture recognition performance is excellent. In addition, under the ablation experiment, the error accuracy of the research model decreased by more than 5 mm, and the overall error accuracy decreased by 10%. In the P-R curve, the accuracy rate of the model reaches 0.741, and the recall rate reaches 0.65. When conducting empirical analysis, the virtual posture disassembly action is complete; the disassembly error is less than 5%, and the disassembly error accuracy is good. The fit degree of the leg bending amplitude reaches over 96%, and the fit degree of the arm bending amplitude reaches over 95%. When the model is applied to actual teaching, the overall satisfaction score of teachers and students reaches 94.6 points. This has effectively improved the teaching effect of art design and is of great significance to the development of education in China.

Recommendation algorithms can greatly improve the efficiency of information retrieval for users. This article briefly introduced recommendation algorithms based on association rules and algorithms based on interest and emotion analysis. After crawling music and comment data from the NetEase Cloud platform, a simulation experiment was conducted. Firstly, the performance of the Back-Propagation Neural Network (BPNN) in the interest and emotion-based algorithm for recommending music was tested, and then the impact of the proportion of emotion weight between comments and music on the emotion analysis-based algorithm was tested. Finally, the three recommendation algorithms based on association rules, user ratings, and interest and emotion analysis were compared. The results showed that when the BPNN used the dominant interest and emotion and secondary interest and emotion as judgment criteria, the accuracy of interest and emotion recognition for music and comments was higher. When the proportion of interest and emotion weight between comments and music was 6:4, the interest and emotion analysis-based recommendation algorithm had the highest accuracy.

推荐算法可以极大地提高用户信息检索的效率。本文简要介绍了基于关联规则的推荐算法和基于兴趣和情感分析的推荐算法。从网易云平台抓取音乐和评论数据,进行仿真实验。首先测试了反向传播神经网络(BPNN)在基于兴趣和情感的音乐推荐算法中的性能,然后测试了评论和音乐之间的情感权重比例对基于情感分析的算法的影响。最后,对基于关联规则、用户评分、兴趣和情感分析的三种推荐算法进行了比较。结果表明,当BPNN以主导兴趣和情感和次要兴趣和情感作为判断标准时,对音乐和评论的兴趣和情感识别准确率更高。当评论与音乐的兴趣和情感权重比例为6:4时,基于兴趣和情感分析的推荐算法准确率最高。基于兴趣和情感的推荐算法比基于关联规则和基于用户评分的推荐算法具有更高的推荐准确率,可以为用户提供更加个性化和情感化的音乐推荐。关键词:兴趣与情感;推荐算法;音乐;个性化

—Driven by the development of multimedia, the encryption of multimedia digital audio has received more attention; however, cryptography-based encryption methods have many shortcomings in encryption of multimedia information, and new encryption methods are urgently needed. This paper briefly introduced cryptography and chaos theory, designed a chaos-based encryption algorithm that combined Logistic mapping and Sine mapping for confusion and used a Hopfield chaos neural network for diffusion, explained the encryption and decryption process of the algorithm, and tested the algorithm. It was found that the keys obtained by the proposed algorithm passed the SP800-22 test, and the correlation between the three encrypted audio and the original audio was 0.0261, -0.0536, and 0.0237, respectively, all of which were small, and the peak signal-to-noise ratio (PSNR) values were -0.348 dB, -7.645 dB, and -3.636 dB, respectively, which were significantly different from the original audio. The NSCR and UACI were also closer to the original values. The results prove that the proposed algorithm has good security and can encrypt the actual multimedia digital audio.
在多媒体技术发展的推动下,多媒体数字音频的加密越来越受到人们的关注;然而,基于密码学的加密方法在多媒体信息的加密中存在许多不足,迫切需要新的加密方法。本文简要介绍了密码学和混沌理论,设计了一种基于混沌的加密算法,该算法采用Logistic映射和正弦映射相结合的方式进行混淆,使用Hopfield混沌神经网络进行扩散,阐述了算法的加解密过程,并对算法进行了测试。结果发现,本文算法获得的密钥通过了SP800-22测试,三种加密音频与原始音频的相关性分别为0.0261、-0.0536、0.0237,均较小,峰值信噪比(PSNR)值分别为-0.348 dB、-7.645 dB、-3.636 dB,与原始音频差异显著。NSCR和UACI也更接近原始值。结果表明,该算法具有良好的安全性,能够对实际的多媒体数字音频进行加密。
