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.
