Keynote Abstract

Data is growing at an alarming rate. This growth is spurred by varied array of sources, such as embedded sensors, social media sites, video cameras, the quantified-self and the internet-of-things. This is changing our reliance on data for making decisions, or data analytics, from being mostly carried out by an individual and in limited settings to taking place while on-the-move and in the field of action. Unlocking value from data directs that it must be assessed from multiple dimensions. Data’s value can be primarily classified as “information,” “knowledge” or “wisdom”. Data analytics addresses such matters as what and why, as well as what will and what should be done. In recent days, data analytics is moving from being reserved for domain experts to becoming necessary for the end-user. However, data availability is both a pertinent issue and a great opportunity for global businesses. In effect, data ubiquity is helping manufacturers, retailers, mobility sector and logistics firms, for example, foster an integrated decision-making environment supporting real-time, information-based business networks. New IT architectures enabled by big data, internet-of-things, cloud computing, and other technologies are helping optimize a business environment with common real-time data, workflow, and alerting capabilities. Business success will be centered around the timely and effective analysis of the large-scale data sets generated by business and sensor networks and the ways in which organizational insights are used to assess and affect potential impacts and risks to their business. This talk will present recent examples from work in our research team on ubiquitous data analytics and open up to a discussion on key questions relating methodologies, tools and frameworks to improve ubiquitous data team effectiveness as well as the potential goals for a ubiquitous data process methodology. Finally, we give an outlook on the future of data analytics, suggesting a few research topics, applications, opportunities and challenges.

Machine Learning in Estimating of SME Investment Potential in Ukraine
SPEAKER: unknown

ABSTRACT. The aim of this research is to develop a model of SME investment potential assessment, using some of machine learning approaches. The structure of investment potential for SMEs was defined underlining their main characteristic features. It was revealed that the SME investment potential depends on factors of business environment measured by indicators of annual Doing Business Reports developed by World Bank Group. The methodology for assessing the impact of business environment factors on the SMEs investment potential was developed. This methodology is based on the algorithm of machine learning, which is used to design a model for forecasting the investment potential of SMEs. This model allows to determine the degree of influence of parameters on the formation of the SMEs investment potential. It is recommended to use computer language Python for optimization of time and human resources. It provides the opportunity to study the effects of the main drivers (both enhancement and reduction) of SME investment potential aimed at its improvement. The authors examined that estimation results could become the basis for elaboration of recommendations regarding improvement of business environment in Ukraine.

The Neuromarketing ICT Technique for Assessing Buyer Emotional Fatigue

ABSTRACT. The typical consumer receives a steady stream of information at purchase process. In the process of perception of this information he/she must not only find necessary data for him, but also process, analyses it, evaluate and weigh the pros and cons, relate it to his own needs, and at the end to make a decision: to buy or not to buy a certain product. All named factors cause consumer’s fatigue, stress and even aggression. In this case, the buyer can make the wrong choice and the quality of his decisions would deteriorate and it is difficult to make a decision about the purchase in such conditions. The research is aimed at assessing the impact of the elements of the process of purchases on the emotional state of the buyer in the urban retailer. The method to assess the emotional fatigue using GSR and HR has been presented. The elements of purchase process and stimuli affecting the buyer were assessed to find overall fatigue in current shop visiting.

The construction of the algorithm study based on the mathematical model of motion
SPEAKER: Maryna Graf

ABSTRACT. The purpose of this work is the construction of the algorithm study a neural network based on the mathematical model of the motion in remotely piloted aircraft systems (RPAS) or unmanned vehicle aircraft (UAV). Information technologies are considered in the UAV control system to provide two-way information transfer between the on-board computer UAV and the operator. The problem arises in the analysis of big amounts of data with information which come from the operator to the on-board computer and in the opposite direction, as well as with a constant change under the influence of external factors. In case of distorted data transmission or collision with obstacles a hang-up and drop of the UAV is possible. Taking into account the rapid growth of UAV usage for civilian and military purposes, the neural network training algorithm for processing the input signal is offered. It can facilitate the task of data analysis and reduce the likelihood of uncertain situations. This algorithm is designed to predict the development of the situation, increase accuracy, the rate of information transfer and its reliability.

Adaptive Technology for Students' Knowledge Assessment as a Prerequisite for Effective Education Process Management
SPEAKER: Oleh Suprun

ABSTRACT. Despite the rapid development of intellectual systems and their implementation in education process, the knowledge assessment technologies are almost the same as decades ago. This paper presents an intellectual system approach to the students’ knowledge evaluation process, based on adaptive mechanisms development. It is an individual directed systems and it allows to correct the questions complexity levels in real time, depending on the average students’ score and to reduce the examiner’s influence to the evaluation process. Besides, the proposed system allows to consider not only the testing result itself, but also different criteria, like time, used by a student to answer the question. According to this idea, the education assessment should demonstrate not only student’s pure knowledge, but also his skills and ability to use obtained knowledge in different situations. The experimental results that show the system’s effectiveness are presented.

GEOGEBRA AS MEANS OF IMPROVING THE QUALITY OF EDUCATION

ABSTRACT. The article substantiates the use of dynamic mathematics software as effective means of formation of the functional thinking of pupils, which directly impact on the quality of mathematical education. The constructive approaches to solving mathematical problems by GeoGebra, which reduce the weight of analytical calculations and put forward the need for skills to simulate the desired construction, take into account the dependencies between its parameters, visualize positions of possible results, even "see" the desired function, for which you want to define extreme, are described. The authors use GeoGebra in solving extreme problems using methods based on constructing an empirical graph of the relations between the values and defining of extremum, and on the visualisation of spreadsheets of the values of the empirical function and their analysis. The effectiveness of the proposed approach was tested during 2015-2017 and was experimentally confirmed in the work on the research topic "The use of information technology in education" through the organization of math group works for pupils in the Sumy region. We tracked the overall level of academic achievement and its dynamics. Since the scale had two positions (right/wrong) and the results of educational achievements were not dependent on each other, we used the sign test. The statistical check at the significance level of 0.05 confirmed the positive impact of the group works on the quality of mathematical preparation of pupils.

Recommendations based on visual content
SPEAKER: Taras Hnot

ABSTRACT. There is a large number of algorithms to do recommendations for cus- tomers of online platforms. All depends on data sources we have. Widely used approaches are based on transactional data and “ratings” matrixes. For such kind of products as clothes, furniture, hand clocks it is very important to take into account not only some metadata characteristics, but also their “visual look”. Peo- ple always buy clothes not based on only size, sleeves lengths, textile type and so on, but based on how it looks in general. In this thesis, we will show how features vectors of visual content could be extracted and used to enhance recom- mendations.

Development of the Ateb-Gabor filtration method in biometric protection systems

ABSTRACT. The Gabor filter for biometric images has been investigated. Introduced a new Ateb-Gabor filter to improve the quality of fingerprint images. The sequence of filtration and recognition of biometric data is developed. For reliable fingerprint recognition, image correction is required, since interference caused by scanning may distort the lines of the imprints, which creates errors in recognition. The mathematical apparatus of the Ateb-functions provides additional functions for controlling Gabor's filtration, since it has a wider range of filtering options. It has been shown that the use of the Ateb-Gabor filter has a more controlling influence on the image, because in addition there are two parameters of rational numbers that considerably extends the filtration process. The method of filtering images based on the Gabor filter using Ateb-functions is developed. At present, work is being done on the application of a new filter to biometric images, bringing it to a finished software product. A two-dimensional Gabor filter is also developed, which in the future will allow people to recognize their faces.
