The paper presents a case study about using Augmented Reality...

Nowadays, Artificial Intelligence is widely applied in many areas of society, especially in education with Intelligent Teaching Systems, cooperative robots (cobots), chatting robots (chatbots), etc. While the assessment of academic achievement plays an important role in Education with many modern models, including Adaptive testing model based on It...

Optimization is an important and decisive task in science. Many optimization problems in science are naturally too complicated and difficult to be modeled and solved by the conventional optimization methods such as mathematical programming problem solvers. Meta-heuristic algorithms that are inspired by nature have started a new era in computing the...

In the trend of Education 4.0, the assessment of learning results through online tests is increasingly widespread and important because of its usability and mobility. In addition, it is also adaptable in the volatile situations of today’s society such as natural disasters, epidemics, war, etc. The paper presents the results of an empirical study in...

In this paper, the asymptotic distribution for the ratio of the sample kurtoses of two independent datasets is derived. It is then applied to construct the confidence interval and also the hypothesis test for the ratio of the kurtoses of two independent populations. The ability of the introduced technique is studied through a simulation study. The...

In the context of Educational Revolution 4.0, text mining with digital tools plays an important role. Various techniques and softwares have been employed in text mining, among which the clustering technique using Atlas.ti, a German software, is widely used thanks to its versatility and open access. This article presents the results of clustering Ma...

E-learning is a form of teaching with several advantages, especially in the context of disease outbreaks such as COVID-19. In terms of teaching at High Schools, E-learning lectures are utilized both for direct classroom teaching and for online teaching via the Internet. This article presents a dual-use electronic lecture design model (DUEL) with iS...

With the expeditious development of the 4.0 technology era, learning English in non-English speaking countries is more crucial and meaningful than ever. Thus the application of information technology for teaching has been increasingly focused and interested, particularly the application of m-learning to support teaching and learning is also progres...

A bad partition in an ensemble will be removed by a cluster ensemble selection framework from the final ensemble. It is the main idea in cluster ensemble selection to remove these partitions (bad partitions) from the selected ensemble. But still, it is likely that one of them contains some reliable clusters. Therefore, it may be reasonable to apply...

Intrusion Detection Systems (IDS) are designed to provide security into computer networks. Different classification models such as Support Vector Machine (SVM) has been successfully applied on the network data. Meanwhile, the extension or improvement of the current models using prototype selection simultaneous with their training phase is crucial d...

The numbers of confirmed cases of new coronavirus (Covid-19) are increased daily in different countries. To determine the policies and plans, the study of the relations between the distributions of the spread of this virus in other countries is critical. In this work, the distributions of the spread of Covid-19 in Unites States America, Spain, Ital...

This study aims to establish a computational method to predict the processes with almost cyclostationary structure. The primary idea is relied on the estimating of the support of spectra and using the discrete Fourier transform and periodogram of almost cyclostation-ary processes. The simulation study and a real dataset are executed to test the per...

A lot of research has been directed to the new optimizers that can find a suboptimal solution for any optimization problem named as heuristic black-box optimizers. They can find the suboptimal solutions of an optimization problem much faster than the mathematical programming methods (if they find them at all). Particle swarm optimization (PSO) is a...

Features play an important role in image processing. But as not all features are comparable, relative features emerged. From the beginning, low-level features, extracted by experts, have been employed to create difficult models for learning the problem of relative attribute. Knowing these models are limited in generality of their applicability, dee...

One of the most important assumptions in machine learning tasks is the fact that training data points and test data points are extracted from the same distribution. However, this paper assumes the situation in which this fact does no longer hold. Therefore, a task named space adjustment, through which the distribution of the data points in the trai...

During the last decade, ensemble clustering has been the subject of many researches in data mining. In ensemble clustering, several basic partitions are first generated and then a function is used for the clustering aggregation in order to create a final partition that is similar to all of the basic partitions as much as possible. Ensemble clusteri...
