Topic: Data-driven diagnosis: problems and methods
Presentation in Ukrainian
Abstract:
Diagnostics in engineering is a mean of ensuring high quality and durability of products, and in biomedical applications is a mean of determining the patient’s condition. Traditionally at practice the diagnostic methods are based on analytical models, and require a depth knowledge of the physics (biology) of the object of diagnosis, which is not always available in practice. Therefore, the data-driven diagnostics is of particular relevance, which allows building diagnostic models based on point observations with insufficient knowledge of the nature of the diagnosed object. The presentation provides an overview of the main stages of tasks and methods of computational diagnostics, their comparative characteristics and recommendations for choosing a specific method taking into account the specifics of the task.
Resume: In 2000, Sergey Subbotin graduated with honour from Zaporizhzhia State Technical University.. In 2005, he defended the PhD Thesis. In 2007, he was awarded the academic title of Associate Professor. In 2014, he was awarded Dr. Sc, (Dr. habil.sc. ing. Degree). In 2014, he was awarded the academic title of Professor. Since 2000, he has been working at National University “Zaporizhzhia Polytechnic” (former Zaporizhzhia National Technical University). In 2000-2003, he was an Assistant; in 2004-2005, he was a Senior Lecturerr; in 2005–2013, he was an Associate Professor; in 2014-2016, he was a Professor. Since 2016, he has been a Head of the Department of Software Tools.. His major fields of research are computational diagnosis, machine learning, neuro-fuzzy systmes, intelligent optimization.

Topic: Mechanisms of fine tuning of neuroevolutionary synthesis of diagnostic models
Presentation in Ukrainian
Abstract: During performing complex synthesis (structural and parametric) of artificial neural networks (ANN) of complex topologies (for example, recurrent neural networks: RNN and deep neural networks: DNN), neuroevolution is a promising approach. After all, methods of neuroevolution synthesis allow to obtain the appropriate topology and parameters of the neuromodel with less involvement of an external expert, by gradually increasing, increasing the complexity and changing the network parameters. However, neuroevolution synthesis has a significant execution time. There are also sometimes problems with local extremes. That’s why the urgent task is to develop modifications that can be introduced point-by-point during the synthesis process in order to overcome disadvantages that were listed and improve results of using such methods.
Resume: During 2013-2017, studied for a bachelor’s degree at Zaporizhia National Technical University (now: National University “Zaporizhzhia Polytechnic”), in 121 Software Engineering specialty. Received a diploma with honors. In 2017-2019, he continued his master’s degree at Zaporizhia National Technical University. In 2019, he entered the postgraduate course of the National University “Zaporizhzhia Polytechnic”, in 122 Computer Sciences, under the scientific supervision of Dr. Sc., Professor Sergey Subbotin and Dr. Sc., Professor Andrii Oliinyk. On July 27, 2023, he defended his PhD thesis. Since 2019, he worked as an assistant and, later, a senior lecturer at the Department of software tools. Since September 2024, the academic title of associate professor was awarded by the decision of the attestation Board of the Ministry of education and science of Ukraine dated 10.12.2024.
