The Department trains specialists in machine learning, data-mining, image processing algorithms and their applications in natural sciences, economics, finance, etc. The Department’s specialization includes mathematical methods for diagnosing complex systems (including technical and economic ones), analyzing these systems, constructing optimal or near optimal solutions that are based on an indirect, incomplete, or contradictory information.

During training, students receive a fundamental education in different areas of mathematics such as modern algebra and mathematical logic, theory of algorithms, discrete and combinatorial mathematics, mathematical models of artificial intelligence, including the mathematical methods of pattern recognition, machine learning, image processing, probability theory, applied statistics, graphical models.

Attending practical sessions, students acquire a skill of working with modern databases and software, learn modern programming languages and techniques, gain experience in solving applied problems. Students also have practice in research institutions of the Russian Academy of Sciences, innovative companies, financial organizations, etc. To the time of their masters many of them already have papers in scientific journals and top conferences’ proceedings.

The Department prepares professionals in the development and application of mathematical methods to solve various data processing problems such as scoring systems, fraud detection, retails prediction, bioinformatics, natural language processing, computer vision, expert systems, etc.

Special scientific seminars and directions of research:

Algebraic approach to data mining, machine learning and pattern recognition

(Academician of RAS Yu. I. Zhuravlyov, Corresponding Member of RAS K.V. Rudakov, Dr.Sc. V.V. Ryazanov, Dr.Sc. A.G. Dyakonov).

In the framework of an algebraic approach new algorithms are constructed as formulas over initial algorithms (weak learners) or as Boolean functions (logic correctors). The main result is that every algorithm can be presented as a superposition of a recognition operator and a decision rule. It allows one to describe the algorithm results as special matrices – the estimate matrices (outputs of recognition operators) and the result matrices (outputs of decision rules). Operations over algorithms are induced by operations over the corresponding estimate matrices. The algebraic approach allows one to construct formulas over algorithms, the formulas that are correct on the test set (or have better performance than initial algorithms).

Computational learning theory and machine learning applications

(Dr. K. Vorontsov)

One of the most challenging problems in machine learning research is analyzing the general performance of a learning machine. A combinatorial theory of overfitting which gives tight and in some cases exact generalization bounds is developed. These bounds are applied to designing learning algorithms in such machine learning subareas as the ensemble learning, rule induction, the distance learning, features selection, prototype selection. Another research direction is information retrieval, collaborative filtering, and probabilistic topic modeling with applications to the analysis of big collections of scientific documents.

Continuous models in image shape analysis and classification

(Prof. L. Mestetsky)

Approaches and methods of objects shape representation in digital images by continuous models are investigated. Human eye does not see the discrete nature of digital images. Images look like continuous pictures, and it is more customary and simpler to operate “solid” continuous geometric models of the shape. Therefore the use of continuous models significantly simplifies the creation of algorithms for analyzing, classifying, and transforming image shapes. The concept of a figure as a universal continuous model of shape is used. A figure is defined as a closed domain whose boundary consists of the finite number of nonintersecting Jordan curves. Three interconnected methods of figure representation are investigated; these are boundary, medial and circular descriptions. The task of constructing the continuous model for the digital image is reduced to the approximation of this image by continuous figures. Then efficient computational geometry algorithms are applied for the shape analysis and related classification of discrete objects in digital images.

Bayesian Methods in Machine Learning

(Dr. D. Vetrov and D. Kropotov)

The research work is focused on investigating the Bayesian approach in the probability theory and its application for solving different machine learning and computer vision problems. Bayesian methods have become a wide-spread technique in the last 15 years. Their main advantages include an automatic tuning of structural parameters in machine learning models, a correct way for reasoning in case of uncertainty, a possibility of considering structural and probabilistic interactions in data arrays (based on actively developing graphical models concept), and an approach for data and model parameter representation that allows an easy fusion of indirect observations and prior ideas.

The developed techniques are intensively used for solving different applied problems including gene expression analysis in animal brains during cognitive processes.

Data Mining: New Challenges and Methods

(Dr. S. Gurov)

The related seminar is designed for 2nd-5th year students, graduate students and anyone interested. It takes place in the spring semester in the form of reports of the participants and invited experts. Topics are diverse. They include (but not limited to) the hypothesis of compactness in pattern recognition; the solution of Boolean equations and synthesis of control circuits; mathematical methods for the analysis of brain activity; characteristics of partially ordered sets; detection of the latent image-based processing of radiographs and photographs of paintings; analysis of formal concepts in applied problems.

Clustering problems

(Academician of RAS Yu. Zhuravlev and Dr. V. Ryazanov)

There are many clustering algorithms based on different principles and leading to different partitions of a given sample. In the absence of statistical models of data, evaluation and comparison problems of clustering arise. Does the resulting clustering correspond to the objective reality, or just get a partition? Criteria for evaluating the quality of clustering and methods of their calculation are designed. These criteria allow us to construct ensembles of clustering algorithms.

Intellectual data-mining: new problems and methods

(Dr. S. Gurov and Dr. A. Maisuradze)

Data-mining in metric spaces

(Dr. A. Maisuradze)

Analysis and estimation of information contained in images

(Dr. I. Gurevich)

Logical methods of pattern recognition

Combinatorial methods of information theory

(Dr. V. Leontyev)
