Abstract Combining images with music is a music visualization to deepen the knowledge and understanding of music information. This study briefly introduced the concept of music visualization and used a convolutional neural network and long short-term memory to pair music and images for music visualization. Then, an emotion classification loss function was added to the loss function to make full use of the emotional information in music and images. Finally, simulation experiments were performed. The results showed that the improved deep learning-based music visualization algorithm had the highest matching accuracy when the weight of the emotion classification loss function was 0.2; compared with the traditional keyword matching method and the nonimproved deep learning music visualization algorithm, the improved algorithm matched more suitable images.

Abstract Nowadays, the modern management is promoted to resolve the issue of unreliable information transmission and to provide work efficiency. The basic aim of the modern management is to be more effective in the role of the school to train talents and serve the society. This article focuses on the application of data mining (DM) in the development of information management system (IMS) in universities and colleges. DM provides powerful approaches for a variety of educational areas. Due to the large amount of student information that can be used to design valuable patterns relevant to student learning behavior, research in the field of education is continuously expanding. Educational data mining can be used by educational institutions to assess student performance, assisting the institution in recognizing the student’s accomplishments. In DM, classification is a well-known technique that has been regularly used to determine student achievement. In this study, the process of DM and the application research of association rules is introduced in the development of IMS in universities and colleges. The results show that the curriculum covers the whole field and the minimum transaction support count be 2, minconf = 70%. The results also suggested that students who choose one course also tend to choose the other course. The application of DM theory in university information will greatly upsurge the data analysis capability of administrators and improve the management level.

A novel method to find the best path in SDN using firefly algorithm 一种利用萤火虫算法寻找SDN中最佳路径的新方法

Abstract Over the previous three decades, the area of computer networks has progressed significantly, from traditional static networks to dynamically designed architecture. The primary purpose of software-defined networking (SDN) is to create an open, programmable network. Conventional network devices, such as routers and switches, may make routing decisions and forward packets; however, SDN divides these components into the Data plane and the Control plane by splitting distinct features away. As a result, switches can only forward packets and cannot make routing decisions; the controller makes routing decisions. OpenFlow is the communication interface between the switches and the controller. It is a protocol that allows the controller to identify the network packet’s path across the switches. This project uses the SDN environment to implement the firefly optimization algorithm to determine the shortest path between two nodes in a network. The firefly optimization algorithm was implemented using Ryu control. The results reveal that using the firefly optimization algorithm improves the selected short path between the source and destination.
在过去的三十年里,计算机网络领域从传统的静态网络发展到动态设计的体系结构,取得了长足的进步。软件定义网络(SDN)的主要目的是创建一个开放的、可编程的网络。传统的网络设备,如路由器和交换机,可以做出路由决定并转发数据包;然而,SDN通过分离不同的特性将这些组件划分为数据平面和控制平面。因此,交换机只能转发数据包,不能做出路由决策;控制器做出路由决策。OpenFlow是交换机和控制器之间的通信接口。它是一种协议,允许控制器识别网络数据包在交换机之间的路径。本项目使用SDN环境实现萤火虫优化算法,确定网络中两个节点之间的最短路径。萤火虫优化算法采用Ryu控制实现。结果表明,采用萤火虫优化算法可以提高源和目标之间选择的短路径。

Abstract The installation error of metallurgical machinery parts is one of the common sources of errors in mechanical equipment. Because the installation error of different parts has different influences on different mechanical equipment, a simple linear formula cannot be used to identify the installation error. In the past, the manual recognition method and the touch recognition method lack of error information analysis, which leads to inaccurate recognition results. To improve the problem, an automatic recognition method based on the neural network for metallurgical machinery parts installation error is proposed. According to the principle of automatic recognition of installation error based on the neural network, the nonlinear relation matrix between layers of the neural network is established. The operating state parameters of mechanical equipment are calculated, and the time series of the parameters are divided into several segments averagely. Based on the recognition algorithm, the inspection steps of depth, perpendicularity and center position of reserved hole, base board construction, short-circuit motor line and terminal installation, center mark board, and reference point installation are designed. The experimental results show that the recall rate of the proposed method is 97.66%, and the maximum absolute deviation is 0.09. The experimental data verify the feasibility of the proposed method.
冶金机械零件的安装误差是机械设备中常见的误差来源之一。由于不同零件的安装误差对不同的机械设备有不同的影响,不能用简单的线性公式来识别安装误差。以往的手工识别方法和触摸识别方法缺乏误差信息分析,导致识别结果不准确。针对这一问题,提出了一种基于神经网络的冶金机械零件安装误差自动识别方法。根据基于神经网络的安装误差自动识别原理,建立了神经网络各层间的非线性关系矩阵。对机械设备的运行状态参数进行了计算,并将参数的时间序列平均分成几段。基于识别算法,设计了预留孔深度、垂直度、中心位置、基板施工、短路电机线路及端子安装、中心标志板、参考点安装等检测步骤。实验结果表明,该方法的召回率为97.66%,最大绝对偏差为0.09。实验数据验证了该方法的可行性。

Abstract A social network image denoising algorithm based on multifeature fusion is proposed. Based on the multifeature fusion theory, the process of social network image denoising is regarded as the fitting process of neural network, and a simple and efficient convolution neural structure of multifeature fusion is constructed for image denoising. The gray features of social network image are collected, and the gray values are denoising and cleaning. Based on the image features, multiple denoising is carried out to ensure the accuracy of social network image denoising algorithm and improve the accuracy of image processing. Experiments show that the average noise of the image processed by the algorithm designed in this study is reduced by 8.6905 dB, which is much larger than that of other methods, and the signal-to-noise ratio of the output image is high, which is maintained at about 30 dB, which has a high effect in the process of practical application.

Abstract The aim of this article was to discuss the modeling and control method of quadrotor unmanned aerial vehicle (UAV). In the process of modeling, mechanism modeling and experimental testing are combined, especially the motor and propeller are modeled in detail. Through the understanding of the body structure and flight principle of the quadrotor UAV, the Newton–Euler method is used to analyze the dynamics of the quadrotor UAV, and the mathematical model of the UAV is established under the small angle rotation. Process identifier (PID) is used to control it. First, the attitude angle of the model is controlled by PID, and based on this, the speed in each direction is controlled by PID. Then, the PID control of the four rotor aircraft with the center of gravity offset is simulated by MATLAB. The results show that the pitch angle and roll angle can be controlled by 5 degrees together without center of gravity deviation, and the PID can effectively control the control quantity and achieve the desired effect in a short time. Classical BP algorithm, classical GA-BP algorithm, and improved GA-BP algorithm were trained, respectively, with a total of 150 sets of training data, training function uses Levenberg-Marquardt (trainlm), and performance function uses mean squared error (MSE). In the background of the same noise, the improved GA-BP algorithm has the highest detection rate, classical GA-BP algorithm is the second, and classical BP algorithm is the worst. The simulation results show that the PID control law can effectively control the attitude angle and speed of the rotor UAV in the case of center of gravity deviation.
摘要本文讨论了四旋翼无人机的建模与控制方法。在建模过程中,将机构建模与实验测试相结合,特别是对电机和螺旋桨进行了详细的建模。通过对四旋翼无人机机体结构和飞行原理的了解,采用牛顿-欧拉方法对四旋翼无人机进行动力学分析,建立了四旋翼无人机小角度旋转下的数学模型。进程标识符(PID)用于控制它。首先,对模型的姿态角进行PID控制,在此基础上对各方向的速度进行PID控制。然后,利用MATLAB仿真了四旋翼飞行器在重心偏移情况下的PID控制。结果表明,俯仰角和横摇角可同时控制5度,无重心偏差,PID能有效控制控制量,在短时间内达到预期效果。分别训练经典BP算法、经典GA-BP算法和改进GA-BP算法,共150组训练数据,训练函数采用Levenberg-Marquardt (trainlm),性能函数采用均方误差(MSE)。在相同噪声背景下,改进GA-BP算法的检测率最高,经典GA-BP算法次之,经典BP算法最差。仿真结果表明,该PID控制律能有效控制旋翼无人机在重心偏离情况下的姿态角和速度。

Abstract Arrhythmias are irregular heartbeats that may be life-threatening. Proper monitoring and the right care at the right time are necessary to keep the heart healthy. Monitoring electrocardiogram (ECG) patterns on continuous monitoring devices is time-consuming. An intense manual inspection by caregivers is not an option. In addition, such an inspection could result in errors and inter-variability. This article proposes an automated ECG beat classification method based on deep neural networks (DNN) to aid in the detection of cardiac arrhythmias. The data collected by an Internet of Things enabled ECG monitoring device are transferred to a server. They are analysed by a deep learning model, and the results are shared with the primary caregiver. The proposed model is trained using the MIT-BIH ECG arrhythmia database to classify into four classes: normal beat (N), left bundle branch block beat (L), right bundle branch block beat (R), and premature ventricular contraction (V). The received data are sampled with an overlapping sliding window and divided into an 80:20 ratio for training and testing, with tenfold cross-validation. The proposed method achieves higher accuracy with a simple model without any preprocessing when compared with previous works. For the train and test sets, we achieved accuracy rates of 99.09 and 99.03%, respectively. A precision, recall, and F1 scores of 0.99 is obtained. The proposed model achieves its goal of developing a simple and accurate ECG monitoring system with improved performance. This simple and efficient deep learning approach for heartbeat classification could be applied in real-time telehealth monitoring systems.
心律失常是指可能危及生命的不规则心跳。在适当的时间进行适当的监测和护理是保持心脏健康的必要条件。在连续监测设备上监测心电图(ECG)模式非常耗时。由护理人员进行密集的人工检查不是一种选择。此外,这样的检查可能导致错误和内部变异。本文提出了一种基于深度神经网络(DNN)的心电心跳自动分类方法,以辅助心律失常的检测。通过物联网功能的心电监护设备采集到的数据传输到服务器。通过深度学习模型对它们进行分析,并将结果与主要护理人员共享。采用MIT-BIH心电失常数据库对模型进行训练,将模型分为正常心跳(N)、左束支传导阻滞心跳(L)、右束支传导阻滞心跳(R)和室性早搏(V)四类。接收到的数据采用重叠滑动窗口采样,按80:20的比例进行训练和测试,并进行十倍交叉验证。与以往的方法相比,该方法模型简单,无需任何预处理,具有更高的精度。对于训练集和测试集,我们分别实现了99.09和99.03%的准确率。得到的精度、召回率和F1分数为0.99。该模型实现了开发简单、准确、性能优良的心电监测系统的目的。这种简单有效的深度学习心跳分类方法可以应用于实时远程健康监测系统。
