Main goal

To develop solutions based on machine learning, mathematical modeling, and large-scale language models for cybersecurity, natural language processing, propaganda and disinformation detection, and image analysis.

  Tasks in 2024:

• Inequalities of zeta functions and distribution of zeros of the zeta function of prime numbers.
• Efficient machine learning algorithms for password selection.
• Content recognition in digitized structured documents.
• Forecasting security prices and investment portfolio formation.
• Efficient algorithms for calculating and visualizing Mandelbrot covers associated with zeta functions.
• Limit theorems for combinatorial numbers.
• Using machine learning to predict the mutation path of viruses.
• Developing an algorithm for recognizing fraudulent websites.
• Analysis of similarity measures between text documents and images.
• Collection and primary analysis of Lithuanian propaganda texts.
• Propaganda and disinformation recognition and analysis of social impact.
• Research and create artificial intelligence algorithms operating in real-time.
