Under the current severe situation of cyber security, it is of great significance to propose an effective anomaly detection approach for ensuring the stability of network. It is generally known that the network traffic data is a kind of typical streaming time series data, which are recorded by network equipments usually accompanied by time instants. In order to detect the anomalous sections in network traffic data effectively, we propose an unsupervised anomaly detection approach based on anomaly definition in time series by utilizing the optimal φ-DTW and the corresponding similarity matrix, which is called ADOPD. Comprehensive experiments have demonstrated that our proposed approach achieves satisfying performance on detecting anomalous in real world data sets.

Stochastic neighbor embedding algorithm is an important nonlinear dimension reduction manifold learning algorithm in the field of big data and machine learning. In the stochastic neighborhood embedding algorithm, it changes the idea of constant distance based on the medium in and, while mapping high-dimensional to low-dimensional, trying to ensure that the distribution probability of each other is consistent. the gradient descent method is often used to solve the problem of minimum divergence, but because the gradient descent method has the disadvantage of easily falling into local optimal values, this article combines SNE with a quantum genetic algorithm and uses the strong uncertainty of the quantum genetic algorithm and high convergence to solve the problem.

IP addresses play a crucial role in the current digital world which deals lakhs of devices and networks. Withthe advent of cloud computing and the Internet of things, the number of devices connected to a network has tripled hence increasing the complexity of networks. this has led to an ever-growing demand for IP addresses. thus Organizations all around the world have to handle the IP address space with care using tools such as IP Address management systems (IPAM). the existing IP Address management systems have several drawbacks such as dependencies on external packages and lack of data harmonization. this paper aims at designing a robust and intelligent IP address management system which overcomes the drawbacks of the existing system. It also comments on the performance of the design based on size, cost, time, and figure of merit. the implemented system reduced the time consumed to manage IP addresses by 98.61% and also reduced the errors in IP Asset data by 36.3%.

We propose a meta-relation network to solve the few shot learning problem, where the classifier must learn to recognize new classes given only few examples from each. Meta-relation networks is based on relation networks and Model-Agnostic Meta-learning (MAML) training methods, which can be trained end-to-end. After training with MAML algorithm, the meta-relation networks can adapt to learning quickly for a small number of samples from a new task with only a small amount of gradient step. It can also classify new classes of images by calculating the scores between query images and few examples of each new class. In experiments, we will demonstrate that the proposed approach leads to good performance on two few-shot image classification benchmarks.

Digitalization encapsulates the importance of machine condition monitoring which is subjected to predictive analytics for realizing significant improvements in the performance and reliability of rotating equipment i.e., spinning. this paper presents a machine learning approach for condition monitoring, based on a regularized deep neural network using automated diagnostics for spinning manufacturing. this article contributes a solution to find disturbances in a running system through real-time data sensing and signal to process via industrial internet of things. Because this controlled sensor network may comprise on different critical components of the same type of machines, therefore back propagation neural network based multi-sensor performance assessment and prediction strategy were developed for our system which worked as intelligent maintenance and diagnostic system. It is completely automatic requiring no manual extraction of handcrafted features.

this paper describes an educational experiment carried out by an Educational Innovation Project (EIP), developed in the field of Industrial Informatics during the biennium 2011/2013 at the Faculty of engineering of Vitoria-Gasteiz (University of the Basque Country, UPV/EHU, Spain). In this paper the general situation regarding the European Higher Education Area (EHEA) at the start of that biennium, as well as the situation and specific problems that occurred in the field of Industrial Informatics at the Faculty are described. It was proposed to rectify the situation by the explicit formulation of ambitious objectives and the use of active learning methods, specifically by intragroup (between members of the same group) and intergroup (between members of different groups) cooperative learning. the paper includes the designing details of the proposed innovation carried out, the designed assessment, and the steps taken for the implementation in each one of the two years of the project. the results have been successful in the academic field since the specific and generic competences have been achieved and even from the point of view of the evaluation of teachers by students.
Convolutional neural network based on machine learning has become one of the most popular methods of image recognition and segmentation, but it needs huge data samples to get better results. In this study, based on U-...

the analysis of bilateral distance between home and host countries is a key issue in the internationalization strategy of companies. As a multi-faceted concept, distance encompasses multiple dimensions, with psychic distance being one of the most critical ones for the overseas investments of firms. Among all the psychic distance stimuli that have been proposed until now, the present paper focuses on Industrial Development Distance (IDD). Together withdata from boththe countries and the companies, IDD is analysed by means of neural projection models based on unsupervised learning, to gain deep knowledge about the internationalization strategy of Spanish large companies. Informative projections are obtained from a real-life dataset, leading to useful conclusions and the identification of those destinations attracting large flows of investment but with a particular idiosyncrasy.
