Topic: Methods and means of creating Galois fields GF(pn) multipliers in FPGA for cyber-physical systems
Presentation in Ukrainian
Abstract: Cryptographic data protection relying on elliptical curves involves employing multipliers of Galois fields, a crucial aspect. In the realm of digital signatures based on elliptical curves, not only prime fields but also extended Galois fields GF(pm) find utility. Within the framework of FPGA devices, cores (VHDL descriptions of digital units) play a structural role. The Galois field multipliers generator constructs VHDL descriptions of multiplier schemes, delineates connections among their components, and generates VHDL descriptions of these components using the Quine-McCluskey Boolean functions minimization method. However, the algorithm’s execution time escalates with larger input data volumes, leading to generation times ranging from a few seconds to several tens of seconds for large characteristic field multipliers. Efforts to streamline design and minimize logic gate count in FPGA are vital for accelerating multiplier operations. The generator devises multipliers based on three variants, and efficacy of using multipliers across fields with differing characteristics is very important. Furthermore, the feasibility of employing extended Galois fields GF(dm) with characteristics d > 2 in data protection mechanisms is very important. It establishes a criterion for comparing data protection tools reliant on such Galois fields and identifies the optimal fields based on the chosen criterion when implemented according to a specific algorithm.

Topic: Distance learning system organization on the basis of formation of a uniform information space
Presentation in Ukrainian
Abstract: Models and methods of identification of input objects based on the formation of a single information space in order to increase the effectiveness of the distance learning system are proposed. The investigated problem is that heterogeneous data sources are used to obtain informational features of objects, which are characterized by different degrees of accuracy and different formats of data presentation. At the same time, the organization of a distance learning system based on the formation of a single information space requires the unification of data obtained from heterogeneous sources and the implementation of a mechanism for converting such formats. There is a contradiction between the heterogeneous nature of features of objects and the requirement of a unified presentation of data. At the same time, the same object, the parameters of which are obtained from different sensors, must be uniquely identified.

Topic: Evaluation and improvement of QoE and QoS parameters in commercial 5G networks: 5G-TOURS approach
Abstract: The 5G-TOURS project aimed at deploying full end-to-end 5G trials involving real end-users and vertical operational services in three different European cities (Turin, Rennes, and Athens). In the 5G-TOURS “ecosystem” realised in the three cities, 13 use cases related with the themes of the touristic city (5 use cases), the safe city (4 use cases) and the mobility-efficient city (4 use cases) have been deployed. The ultimate goal of this approach was to trial the use cases in real environments to continuously collecting network, service and vertical KPIs and then to evaluate them against a set of predefined verticaloriented criteria.
The results from the application of such QoS/QoE estimation methodology on the use cases are presented. By following the 5G-TOURS QoS/QoE methodology, the level of satisfaction of end-users and verticals’ players in the use cases were measured and evaluated. This evaluation included users’ QoE as well as the feedback from the vertical players on how the technology provided can improve their business operations. The final 5G-TOURS evaluation methodology was followed in the trial execution of all use cases. Initially, during the actual trial execution, both the QoS metrics, automatically obtained from the infrastructure, and the QoE metrics (and vertical satisfaction), were collected using appropriate questionnaires. Then, all the collected metrics were analysed and the KPIs calculated and validated against the predefined targets. In addition, insights were provided in the case of successful validation results, while a justification in case of not fulfilled KPIs. Besides, in selected use cases, models for QoS/QoE correlation were created by using correlation-regression analysis.

Topic: Intelligent Decision Support System when Controlling Drilling
(Presentation in Ukrainian)
Abstract: The development of the oil and gas industry has always relied on industrial data to conduct production activities. This branch of industry is one of the few that first introduced the use of low-level data transmitters. Oil and gas companies have long been collecting data from their oil and gas wells to monitor the progress of relevant technological operations and to model the life cycle of relevant industrial facilities. Today, oil and gas companies collect various types of data at a fast pace and in huge volumes. This includes drilling and production data, GPS and spatial data, seismic data, general industrial data, weather information (especially for offshore drilling), and event logging data (field development histories). Much of this data is unstructured or loosely structured, which raises relevant questions about the storage, integration and access to such data using traditional and emerging technologies of databases, data banks, data warehouses, knowledge bases and knowledge oriented technologies in general.

Topic: Statistical-clustering analysis of information in complex networks.
Presentation in Ukrainian.
Abstract: The research of statistical characteristics of complex networks e.g. WWW is proposed. We have developed application which was used for gathering statistical information of web pages. Several zones within the Ukrainian, Israeli and Polish Domains were researched. Comparison of statistical characteristics of researched domains shows that they are fully developed structures and meet the modern trends of the Internet. It is shown that the properties of an undirected graph depend on the subnets of input and output connections. The research of the cluster structure of several zones of the web space on the basis of the previously collected statistical data is performed. The efficiency and visibility of the РІС clustering algorithm (Рower iteration clustering) is demonstrated. The results of finding the optimal number of clusters are performed by two methods: the Elbow Method and the k-Core decomposition method. A new method of finding the optimal number of clusters and cluster centers is also proposed. New algorithm is based on the distribution of eigenvalues of the stochastic matrix, which describes the process of Markov transitions in the system. The result of all conducted research is information technology, with the help of which statistical and cluster analysis of information in complex networks is done.

Topic: Deep learning and inductive inference technologies composition for the development of ontology-related systems.
Abstract: The workshop called “Deep learning and inductive inference technologies composition for the development of ontology-related systems” is dedicated to a new technique of semantic language modeling for ontology-related systems development. Our method relies on the composition of deep learning technologies (using the revised technique for the distributional semantic modeling – word embeddings applying the ontology-related approach) and inductive inference (using the growing pyramidal networks). Also, the semantic maps of relations between words can be represented as a graph using Vec2graph – a Python library for visualizing word embeddings (term embeddings in our case) as dynamic and interactive graphs. The Vec2graph library coupled with term embeddings will not only improve accuracy in solving standard NLP tasks but also update the conventional concept of automated ontology development.

Topic: Fourier Transform and Other Quadratic Problems under Interval Uncertainty
Presentation in English
Abstract: Computers are used to estimate the current values of physical quantities and to predict their future values – e.g., to predict tomorrow’s temperature. The inputs x1,…, xn for such data processing come from measurements (or from expert estimates). Both measurements and expert estimates are not absolutely accurate: measurement results Xi are, in general, somewhat different from the actual (unknown) values xi of the corresponding quantities. Because of these differences Xi — xi (called “measurement errors”), the result Y = f(X1,…,Xn) of data processing is also somewhat different from the actual value of the desired quantity y – at least from the value y = f(x1,…,xn) that we would have obtained if we knew the exact values xi of the inputs.
In many practical situations, the only information that we have about measurement uncertainty is the upper bound Di on the absolute value of each measurement error. In such situations, if the measurement result is Xi, then all we know about the actual value xi of the corresponding quantity is that this value is in the interval [Xi – Di, Xi + Di]. Under such interval uncertainty, it is desirable to know the range of possible value of y.
In general, computing such a range is NP-hard already for quadratic functions f(x1,…,xn). Recently, a feasible algorithm was proposed for a practically important quadratic problem – of estimating the absolute value (modulus) of Fourier coefficients. In this talk, we show that this feasible algorithm can be extended to a reasonable general class of quadratic problems.

Topic: Intelligent Information Technology for Supporting the Medical Decision-Making Considering the Legal Basis
Abstract: The decision support system (DSS) and information technology (IT) in the field of medical law are designed to provide the possibility of free and automated verification of all significant conditions of the contract and provide recommendations for the conclusion of the contract or not. Modern decisions for support the adoption of medical decisions on legal basis have shown that none of the known decisions does meet all the necessary criteria in the complex. Therefore, an urgent problem for Ukraine is the development and implementation of intelligent information technology to support medical decision-making, taking into account the legal basis, which is the purpose of this study. The proposed intelligent information technology to support medical decision-making based on legal basis provides support for decision-making on the possibility of using reproductive technologies (the possibility of surrogacy and/or in vitro fertilization), the possibility of donation and transplantation, the possibility of concluding contracts for therapeutic services, contracts for dental services and general contracts for medical services. In addition, intelligent information technology to support medical decision-making based on the legal basis automates the semantic parsing of contracts and draws conclusions about the possibility or impossibility of concluding a contract, as well as provides a request stating the reasons for impossibility to conclude a contract (for example, indicating missing essential conditions), if it was concluded that such a contract cannot be concluded.

This need is realized in the development of recommendations, regulations, and standards to maximize the benefits from the use of AI and minimize the possible risks. The regulatory framework is built on a human-centric basis. According to the developed standards should form the basis for further activities aimed at the application of AI and be applicable at all stages of the creation of practical solutions. Therefore, an important step is to formalize the requirements, principles and provisions of legal and ethical norms in the form of practical templates of practical application. With this method, the study developed models and ontologies of the standardized concept of trustworthiness for AI. This allowed to determine the basic concepts, which allow forming a position of trust, are a substantial part of the concept of AI trustworthiness, determine the necessity of its existence and pose a threat to it. On the basis of the subject domain ontology the models were developed and further decomposition of structural meaningful concepts was performed. Further defined the characteristics of the concept of trust formation. Machine learning methods have been proposed that allow dividing into interpreted and non-interpreted decisions within the framework of the concept of trust. Among the non-interpreted decision a method for improving the values of the target quality function using the grouping of an ensemble of models by the correlation of the decisions made is proposed. Also proposed a method for data features regularization in order to identify atypical features and feature outliers in the non-interpreted decisions based on the grouping of decisions in a single-class classification. Thus developed the model of confidence in AI allowed to determine the basic requirements in accordance with which were developed methods of obtaining decisions based on ensembles with maximization of the target function and the method of analysis of transient data features.

Topic: Models, Methods and Means of Resilient Computing
Presentation in Russian
Abstract: The resource-based approach is proposed, which analyzes the integration of models, methods and means of the computer world into the natural one. The current state of the computer world resources (models, methods and means) is assessed. The vector of development of resources and the levels of this development are determined: replication, diversification and self-sufficiency as the goal of development. Dominance of replication, which is the lowest level of development, is noted. The main challenges in the development of computer resources are considered, and it is also shown how to resiliently develop models and methods. Real examples are given, the absence of which would make all the above arguments untenable.

Topic: Fast Pattern Recognition using Combined Learning of Neural Networks
Presentation in Ukrainian
Abstract: The adaptive probabilistic neural network and neuro-fuzzy system for classification task in situation of overlapping classes are proposed. These systems are designed to solve data classification task when data are fed sequentially in the online mode, and forming classes are mutually overlapped – the fuzzy case. The distinct feature of the systems is that the learning process of the pattern layer uses the sliding window and combined tuning. This allows us to keep the constant number of neurons in layer. Another point of the learning process is the tuning ability of activation functions’ widespread parameters in online mode. The described advantage allows us to raise the classification quality. Last but not least is the ability to compute both the probability and membership levels of each observation to each of forming classes. The proposed adaptive probabilistic systems with fuzzy interference are simple in numerical implementation and have high learning speed. The results of experiments confirmed the correctness of approach under consideration.

Topic: Intelligent Information-Analytical Technologies for Improving the Software Quality by Assessing the Sufficiency of Information at Initial Stages of the Life Cycle.
Presentation in Ukrainian
Abstract: The field of software engineering needs special attention in the direction of development and implementation of effective information technologies, in particular, to solve the problem of software quality assurance. Developing high-quality software is a key factor in its effective use and one of the main needs of customers. The need for quality assurance is based on the fact that software errors and failures lead to disasters that lead to human casualties, environmental cataclysms, significant time losses and financial losses.
The critical impact on software projects and the success of their implementation are issues related to the analysis and evaluation of the initial stages of the life cycle. Today, when the number of high-budget software projects is growing rapidly, analysis of the specification of software requirements is actual. The possibility of automated assessment of the initial stages of the software life cycle, in particular, identifying and eliminating shortcomings of the initial stages of the software life cycle and the facts of the insufficiency of information, which is relevant to them, is actual too (moreover special attention needs to be paid to information about the non-functional characteristics of the software).
The need to ensure the quality of software, the presence of information losses in the formation and formulation of software requirements, the need to identify and eliminate insufficiency of information at the initial stages of the software life cycle creates an urgent scientific and applied problem, one way to solve which is to develop intelligent information technology for improving the quality of software by assessing the sufficiency of information in the early stages of the life cycle, which will provide the ability to identify lack of quality information in the specifications of the requirements in the early stages of the software life cycle and the ability to generate requests to supplement requirements by such information, which together will allow to assess the current situation and provide the appropriate level of quality at later stages of the software life cycle.
The presentation is devoted to solving the current scientific and applied problem of improving the quality of software in the early stages of the life cycle by assessing the sufficiency of information on quality in the specifications of software requirements. Developed intelligent information-analytical technologies for improving the quality of software by assessing the sufficiency of information in the early stages of the life cycle: will increase the level of sufficiency of information of requirements for determining the quality of software, thereby reducing the gap in knowledge about software projects; will provide a conclusion on the sufficiency of information on quality in the specification of requirements; will determine the priority of supplementing the specification with the necessary information (in case of insufficient information); will provide a quantitative assessment of the level of sufficiency of the quality information, which is available in the specification; will provide the opportunity to process quality information in the software requirements specifications by intelligent agents, without the participation of specialists, which will eliminate the subjective influence of specialists and the safety of this information in the software company in case of dismissal of specialists. The developed information-analytical technologies will automatically process the existing knowledge (quality requirements from the specification) and will form new knowledge (conclusions about the sufficiency of information, about the level of information sufficiency, recommendations for improving the sufficiency of information in the specification requirements). Developed intelligent information-analytical technologies will increase the sufficiency of information on quality in the specifications of software requirements to 100% – if it’s necessary (for critical application systems) or at the request of the customer.

Topic: The hierarchical classifier for COVID-19 resistance evaluation.
Presentation in Ukrainian
Abstract: Finding dependencies in the data requires the analysis of relations between dozens of parameters of the studied process and hundreds of possible sources of influence on this process. Dependencies are nondeterministic and therefore modeling requires the use of statistical methods for analyzing random processes. Part of the information is often hidden from observation or not monitored. That is why many difficulties have arisen in the process of analyzing the collected information. The paper aims to find frequent patterns and parameters affected by COVID-19. The novelty of the paper is hierarchical architecture comprises supervised and unsupervised methods. It allows the development of an ensemble of the methods based on k-means clustering and classification. The best classifiers from the ensemble are Random Forest with 500 trees and XGBoost. Classification for separated clusters gives us higher accuracy on 4% in comparison with while dataset analysis. The proposed approach can be used also for personalized medicine decision support in other domains. The features selection gives us to analyze the following features with the highest impact on COVID-19.

Topic: Techniques of gene expression profiles processing for purpose of gene regulatory networks reconstruction.
Presentation in Ukrainian
Abstract: The main direction of our research is focused to gene expression profiles processing for purpose of both gene regulatory network reconstruction and validation of the reconstructed models. This problem is one of the main directions of current bioinformatics.
The experimental foundation for our research are arrays of gene expressions obtained as a result of both DNA microarray experiments or RNA molecules sequencing technique. Gene expression in this case means a level of gene activity. This value is proportional to the number of genes that correspond to the appropriate type of protein in the biological organism.
Gene expressions profile is a vector of gene expressions determined for differed samples or different conditions of the experiment performing. Reconstruction of gene regulatory networks and further simulation of the reconstructed models form the basis for investigation and analysis of both the character of molecular systems elements interconnections and influences of these interconnections to functional possibilities of the investigated objects. The complexity of gene network reconstruction is determined by the following: the experimental data which are used for the reconstruction process usually does not allow defining the network structure and pattern of genes interconnection in the network. Moreover, a large quantity of genes complicates the interpretation of the network elements interconnections. In this case, it is necessary to conduct research concerning: experimental data pre-processing to determine the optimal ways of gene expression array formation; gene expression profiles reducing for purpose of informative genes allocation in terms of quantitative quality criteria; evaluation of both the network topology and the pattern of genes interconnection in the network with the use of experimental data obtained by the use of both DNA microchip experiment or RNA-molecules sequencing method. A qualitatively reconstructed gene regulatory network allows investigating the pattern of the biological organism development at the genetic level. It creates the conditions for both making new effective medicines and the development of methods of early diagnostics and effective treatment of complex diseases. This fact indicates the actuality of the research in this subject area.
Within the framework of this presentation, I would like to describe briefly a stepwise procedure of the gene expression data formation, pre-processing, and informative genes extraction for the purpose of both the gene regulatory network reconstruction or diseases diagnostic system creation.
