Third session of the Winter School ‘Digital Detectives with Big Data’

On 2 February 2026, as part of the Winter School ‘Digital Detectives with Big Data’, two interactive online lectures were held: ‘Digital Detectives: Big Data in Your Phone’📈. The events were conducted by Alina Yurievna Yefimenko, assistant professor of the Department of Economic Cybernetics. The events brought together 37 schoolchildren. Pupils from grades 9-A and 9-B of Sumy Secondary School No. 15 were able to immerse themselves in the world of Big Data using modern information technologies and take part in an interactive quiz entitled ‘Social Networks VS Big Data’.
During the training, the students considered:
• the concept of Big Data;
• Big Data in economics;
• the relationship between consumer behaviour, business optimisation and market trends;
• the capabilities of the Kaggle platform;
• they solved real-life problems in the context of social media monitoring.
During the event, a representative of the department introduced students to the specialities of the Sumy State University’s Faculty of Economics and Management, and also talked about the features of the ‘Economic Cybernetics’ educational programme, which opens up prospects for a deeper study of modern economic models, the use of big data and mathematical methods.
