The paper presented a new wave acquisition stereo system to estimate significant wave height based on stereo (binocular) vision. Using binocular vision, wave transformation in near shore water can be measured in wave altitude. The total measurement numbers are 1024 times. Wave vertical altitudes can be extracted from the datum according to binocular vision. With the help of 3D Fourier transform, the wave surface data can be turned into wave spectrum. By analyzing the wave spectrum, significant wave height can be estimated. Experimental results have shown that the method is effective.

Hyperspectral images usually have higher spectral resolution but lower spatial resolution, compared with the multispectral images. Low spatial resolution brings difficulties to the practical applications of hyperspectral images. Therefore, to get high spatial resolution hyperspectral image, it is very important to fuse low spatial resolution hyperspectral image with the high spatial resolution multispectral image in the same scene. In this paper, we propose a hybrid regularization model by integrating sparse prior, local low-rank regularization and total variation based on l2 norm to reconstruct high spatial resolution hyperspectral images. In addition, we design an alternating direction method of multipliers (ADMM) to solve it. The experimental results show the superiority and competitiveness of our method over the state-of-the-art methods.
与多光谱图像相比,高光谱图像通常具有更高的光谱分辨率,但空间分辨率较低。低空间分辨率给高光谱图像的实际应用带来了困难。因此,为了获得高空间分辨率的高光谱图像,将同一场景下的低空间分辨率高光谱图像与高空间分辨率多光谱图像融合是非常重要的。本文提出了一种基于l2范数的混合正则化模型,将稀疏先验、局部低秩正则化和全变分相结合,用于高空间分辨率高光谱图像的重建。此外,我们设计了一种乘法器交替方向法(ADMM)来解决这个问题。实验结果表明,该方法与现有方法相比具有优越性和竞争力。

With the development of power industry, electricity has become one of the most important energy sources in our country, related to the lifeline of the country's economy. The electricity system is becoming more and more mature, but abnormal electricity consumption behaviors are also emerging endlessly, causing potential safety hazards in the electricity industry and even the electricity supply system. Considering the lack of abnormal annotations in the electricity load data, this paper proposes a semi-supervised electricity load data anomaly detection method based on MixMatch. Firstly, data cleaning of electricity load data is used to remove incorrect data. Secondly, Convolutional Autoencoder (CAE) is used to extract its time-domain and frequency-domain features separately, and the features are combined through feature fusion. Thirdly, the Borderline Synthetic Minority Oversampling Technique (Borderline-SMOTE) is used to solve the problem of data imbalance. The MixMatch semi-supervised algorithm is used to label the abnormal data to realize the anomaly detection of the electricity load data. Finally, this paper uses the k-means clustering and T-Stochastic neighbour Embedding (T -SNE) to classify the abnormal data and visualize the data. The experimental results show that, compared with traditional machine learning methods, the proposed method has a significant improvement on AUC.
随着电力工业的发展,电力已成为我国最重要的能源之一,关系到国家经济的命脉。电力系统日趋成熟,但异常用电行为也层出不穷,给电力行业乃至供电系统带来安全隐患。针对电力负荷数据中缺乏异常标注的问题,提出了一种基于MixMatch的半监督电力负荷数据异常检测方法。首先对电力负荷数据进行数据清洗,去除不正确的数据。其次,利用卷积自编码器(Convolutional Autoencoder, CAE)分别提取其时域和频域特征,通过特征融合将特征组合在一起;第三,采用边界合成少数过采样技术(Borderline- smote)解决数据不平衡问题。采用MixMatch半监督算法对异常数据进行标注,实现对电力负荷数据的异常检测。最后,利用k-均值聚类和T-随机邻居嵌入(T -SNE)对异常数据进行分类和可视化。实验结果表明,与传统的机器学习方法相比,本文提出的方法在AUC上有显著提高。

In the intensive computing scenario with the application of micro-service framework, it is too costly to allocate resources centrally to the micro-service instance on the server side, and it cannot adapt to the changes of the environment in real time. Therefore, allocating resource for micro-service instance distributed on the terminal becomes an effective way to solve the problem mentioned above. A client-based micro-service discovery algorithm with attractor selection model is proposed in this paper, which has the characters of simple and intelligent evolution. At first, this paper models micro-service discovery problem, defines optimization object and constraints; then, it re-defines the parameters of attractor selection and proposes the client-based micro-service discovery algorithm with attractor selection model; and at last, it analyzes the performance of the proposed algorithm with the compared ones in the really productive environment. The experiment results show that the proposed algorithm reduces almost 32 % resource fragments and 70% running time than the compared ones.

As the self-occlusion or occluded 3D point clouds objects in complex scenes, which could affect the accuracy of objects classification, we propose Optimal Combination of Multidimensional Features based on deep learning for large-scene laser point clouds in classification. We construct the optimal combination matrix of multidimensional features by extracting the three-dimensional features of the three-dimensional point cloud and the two-dimensional features in multiple directions. The multidimensional optimal combination features are introduced into the convolutional network. The experimental results show that effectiveness of classification for large-scale point clouds, the effectiveness of 3D feature of point cloud is higher than that of 2D feature. The classification accuracy of our method can reach 98.8% on the Large-Scene Point Cloud Oakland data set, which obtains the better classification accuracy than other classification algorithms the paper mentioned.

One of the most commonly used natural language processing technologies is text classification. Spam detection, news text classification, information retrieval, emotion analysis, and intention judgment, among other applications, are all popular text classification applications [25]. Text classification is the process of assigning pre-defined class labels to text documents in order to shape semantic classes. Engineering, medical science, life science, social sciences and humanities, marketing, and government are only a few of the real-world applications. Machine learning and deep learning algorithms have recently become common and efficient methods for dealing with text classification problems involving labeled data [26]. The primary goal of text classification is to automatically assign texts to pre-defined categories based on their content. In this study, we will conduct a comparative study of the accuracies of different deep learning methods that include Bidirectional Encoder Representations from Transformers (BERT), Recurrent Neural Network (RNN), Convolutional Neural Network (CNN), and Region-based convolutional neural networks and compare the effectiveness of these deep-learning approaches in classifying Chinese news title text using the THUCNews dataset.
文本分类是最常用的自然语言处理技术之一。垃圾邮件检测、新闻文本分类、信息检索、情感分析、意图判断等都是比较流行的文本分类应用[25]。文本分类是将预定义的类标签分配给文本文档以形成语义类的过程。工程、医学、生命科学、社会科学和人文科学、市场营销和政府只是实际应用中的一小部分。机器学习和深度学习算法最近已经成为处理涉及标记数据的文本分类问题的常见而有效的方法[26]。文本分类的主要目标是根据文本的内容自动将文本分配到预定义的类别中。在这项研究中,我们将对不同深度学习方法的准确性进行比较研究,包括来自变形器的双向编码器表示(BERT)、循环神经网络(RNN)、卷积神经网络(CNN)和基于区域的卷积神经网络,并比较这些深度学习方法在使用THUCNews数据集分类中文新闻标题文本方面的有效性。

Aiming at the switching control model of hybrid system, the stability of hybrid system is discussed. Combined with the typical switching control model, the sufficient conditions for the hybrid switching system to remain stable when the switching discrete state is changed and the system energy is increased are given. By dividing the switched system into a more reasonable area and adjusting the control law in time, the optimal control of the switched system is achieved. The stability condition of traffic signal switching control is verified by simulation with the traffic signal switching model of key traffic nodes (regions) in unbalanced road network based on hybrid system model. The experimental results show that the hybrid switched control system has more outstanding advantages than the discrete dynamic and continuous dynamic systems in urban traffic signal control.
针对混合系统的切换控制模型,讨论了混合系统的稳定性。结合典型的切换控制模型,给出了当切换离散状态改变和系统能量增加时混合切换系统保持稳定的充分条件。通过将切换系统划分为更合理的区域,并及时调整控制律,实现切换系统的最优控制。利用基于混合系统模型的非平衡路网关键交通节点(区域)交通信号切换模型,仿真验证了交通信号切换控制的稳定性条件。实验结果表明,混合切换控制系统在城市交通信号控制中比离散动态和连续动态系统具有更突出的优势。

Combined with the typical switching control model, the sufficient conditions for the hybrid switching system to remain stable when the switching discrete state is changed and the system energy is increased are given. By dividing the switched system into a more reasonable area and adjusting the control law in time, the optimal control of the switched system is achieved. The stability condition of traffic signal switching control is verified by simulation with the traffic signal switching model of key traffic nodes (regions) in unbalanced road network based on hybrid system model. The experimental results show that the hybrid switched control system has more outstanding advantages than the discrete dynamic and continuous dynamic systems in urban traffic signal control.","PeriodicalId":331409,"journal":{"name":"2021 International Conference on Computer Engineering and Artificial Intelligence (ICCEAI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116983811","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}
