IMPACT ANALYSIS OF PROFILE INJECTION ATTACKS IN RECOMMENDER SYSTEM

Recommender systems are the backbone of all the prediction-based service platforms e.g. Facebook, Amazon, LinkedIn etc. Even companies now a days are using the recommender systems to show users personalized ads. These service providers capture the right audience for their services/ products and hence, improve overall sales. Social networking platforms are using recommender systems for connecting people of similar interests which is almost impossible without recommender systems. Collaborative filtering-based recommender system is most widely used recommender system. It is used in this research to predict the rating for a specific movie. Accuracy of the prediction define the performance of the overall system. The quality of predictions is degraded by the attackers by injection of fake profiles. In this paper, the various types of profile injection attacks are explained and the attack scenario gets extended to measure the performance of these attacks. Empirical results on the real world publicly available data set shows that these attacks are highly vulnerable. The impact of these attacks in several conditions has been measured and it is tried to find the scenarios where these attacks are more powerful.

The Importance Of National Ideology In The Educational Process

In the usual sense, ideology is not a science, although it includes scientific knowledge. The difference between ideology and science lies in the fact that it includes not only scientific knowledge and knowledge about socio-political life, but also an assessment of current events, trends, processes and various forces of this socio-political life. Strictly speaking, ideology does not exist in isolation from socio-political, national, economic, class and other communities and groups. It arises with them, forms and changes as their life cycle progresses, reflecting the interests of groups united by a given ideology.
Features of the spiritual and moral development of high school students

The need for a spiritual and moral revival of Kazakhstan’s society is due to the fact that it is undergoing a crisis that is a reflection of the global civilization crisis (the spread of religious sects, the operation of terrorist organizations and other destructive structures). Currently, in order to preserve socio-economic stability in Kazakhstan’s society, it is necessary to solve the problem of personal crisis, which manifests itself as a crisis of its spirituality. Therefore, in education, it becomes relevant to study the approaches to the spiritual and moral development of high school students in the framework of the implementation of the NDO Self-Cognition Program. In order to reveal the peculiarities of the spiritual and moral development of a high school student in the context of the implementation of the Self-Knowledge NDO Program, we need to study the problems of the spiritual and moral development of the individual as a whole. A lot of researches have been devoted to the study of the problems of the spiritual and moral development of the individual, but the generally accepted theory still does not exist, since the concept of «spiritual and moral development» is inherently interdisciplinary. The authors consider the diversity of conceptual approaches in understanding the essence of this process, as well as the essence of the concepts of «spirituality» and «morality» in philosophy, psychology and pedagogy.
Securing Helwan University Graduation Temporary Certificate against the risks of forgery and counterfeiting by/ using security features

Helwan University graduation is a very valuable authentic document, like any graduation temporarycertificate all over the universities. It is issued for graduates who need it to present to everyone or firm who is interested. However, it is not secured with any security feature that prevent forgery, tampering or altering the information of the certificate by using any professional image processor application like Photoshop. So there was an urgent need to introduce an innovative design that achieves two goals, first of all is securing the certificate against counterfeiting and forgery, secondly, creating an aesthetic appeal to it.  So the research hypothesis was that creating an innovative decorative design supported with some suggested security features like Guilloche, Micro-printing, Optically Variable Inks (OVI) and printed Radio frequency Identification (RFID) tag, will definitely achieve these goals, provided do not considerably increase the cost of the produced documents. After experimental work study, the results shown that this innovative design were generated by Adobe Illustrator CC 2015 software, has achieved the research goals.
Virtual Reality and Audiovisual Experience in the AudioVirtualizer

INTRODUCTION: Virtual Reality (VR) provides new possibilities for interaction, immersiveness, and audiovisual combination, potentially facilitating novel aesthetic experiences.OBJECTIVES: In this project we created a VR AudioVirtualizer able to generate graphics in response to any sound input in a visual style similar to a body of drawings by the first author.METHODS: In order to be able to make the system able to respond to any given musical input we developed a Unity plugin that employs real-time machine listening on low level and medium-level audio features.The VR deployment utilized SteamVR to allow the use of HTC Vive Pro and Oculus Rift headsets.RESULTS: We presented our system to a small audience at PROTO in Gateshead in September 2019 and observed people's preferred ways of interacting with the system.Although our system can respond to any sound input, for ease of interaction we chose four previously created audio compositions by the authors of this paper and microphone input as a restricted set of sound input options for the user to explore.CONCLUSION: We found that people's previous experience with VR or gaming influenced how much interaction they used in the system.Whilst it was possible to navigate within the scenes and jump to different scenes by selecting a 3D sculpture in the scene, people with no previous VR or gaming experience often preferred to just let the visuals surprise them.They used mainly head movement to change their point of view, whereas people with previous VR or gaming experience quickly learned inherent capabilities of the system.The AudioVirtualizer system is most suited to respond to electronic soundscapes and microphone input.
Мethodical ways of junior schoolchildren’ mental work culture education

The article reveals the description experience of practical work for junior schoolchildren educating culture of mental work. The cornerstone of any educational concept is the idea of ​​intellectual development of the pupil who finds ways to solve it in different methods, technologies, didactic and educational models. Traditionally, the intellectual development of the student is considered to be the prerogative of didactics. Meanwhile, without mental education it is impossible to form a proper level of intelligence of a child, because didactics equips the individual with applied tools for learning about the world, and successful use of knowledge, skills, abilities and competencies in everyday life is impossible without emotional experience, reflection on personal achievements and development. That helps in organizing, regulating human activities in the world. Modern pedagogical science has an integrated approach in defining the concept of learning ability - it combines the personal characteristics of the student with the semantic and procedural basis of learning and is interpreted as a regulatory universal learning action, mastery of which ensures success in cognitive activity at all stages and levels of education. In a wider context, universal learning activities are considered to be as the ability of the individual to self-development and self-improvement through conscious and active assimilation of social experience. In this sense, they can be correlated with the concept of "culture of mental work", which means a quality that is manifested not only in education but also in other activities – such as playing and working. The purpose of forming a culture of mental work is to develop the child's readiness to implement various activities in society and the biological environment and the formation of a holistic picture of the world, which is constantly recognized and enriched with new intellectual and emotional aspects of meaning. Methodical aspects of mental work culture formation of the younger schoolchildren discover forms of the organization of educational activity of pupils; selection of exercises and tasks that help the child to understand the purpose of each intellectual operation, to comprehend it and integrate it into a holistic system of operations and to master the algorithm of action; development by schoolchildren of own algorithms of educational actions. Such exercises include reflexive tasks, solving puzzles, composing short texts with explanations, establishing analogies, composing riddles and crossword puzzles, problem tasks

Geometrical Approach to a New Hybrid Grid-Based Gravitational Clustering Algorithm

In the past years, several clustering algorithms have been developed, for example, K-means, K-medoid.Most of these algorithms have the common problem of selecting the appropriate number of clusters and these algorithms are sensitive to noisy data and would cause less accurate clustering of the data set.Therefore, this paper introduces a new Hybrid Grid-based Gravitational Clustering Algorithm (HGGCA) geometrically, which can automatically detect the number of clusters of the targeted data set and find the clusters with any arbitrary forms and filter the noisy data.This proposed clustering algorithm is used to move the cluster centers to the areas where the data density is high based on Newton's law of gravity and Newton's laws of motion.Also, the proposed method has higher accuracy than the existing K-means and Kmedoids methods which is shown in the experimental result.In this study, we used cluster-validity-indicators to verify the validity of the proposed and existing methods of clustering.Experimental results show that the proposed algorithm massively creates high-quality clusters.
