Research Work

Research interests. The main area of ​​scientific interest is the development and application of data science methods and technologies including artificial intelligence ones. Research includes the following main directions: reduction of data dimensionality and visualization; optimization theory and applications; visual multidimensional data analysis, artificial neural networks, parallel computing, multicriteria decision making, artificial intelligence, cognitive computing, image and signal analysis. Medical applications include numerical and visual data of various origins - ophthalmologic, cardiological, physiological, thermovision. Computed tomography images are also being investigated. A lot of software is designed both for general purposes and for applications. Various problems of computer-aided design have been solved, too. The author of more than 270 scientific publications, two monographs, five textbooks.

Internationally recognized research group for visual analysis and dimensionality reduction of multidimensional data has been established and developed in Lithuania. 15 doctoral students successfully defenced their PhD thesis and got doctoral degree under his supervision.
