Asymptotic Analysis of Linear and Nonlinear Statistics. Prof. Habil. Dr. K. Kubilius 2013–2015.

The upper bounds of the Lp norms of the normal approximation for random sums of independent identically distributed random variables, where the number of summands is a binomial random variable, are obtained. The methods of construction and simulation of the multivariate distributions of Tweedie are considered. A measure of dependence for symetric α-stable random vectors was considered. Strongly consistent and asymptotically normal estimators of the Hurst parameter and volatility of the nonlinear stochastic diferential equation driven by fBm were obtained. Some goodness-of-fit tests based on the maximum of smooth empirical processes were considered. Nonparametric estimates of large number of rare events distribution were proposed. Asymptotic properties of distribution of finite population statistics were considered. The dependencies of individual sectorial stock price indices of OMX Baltic security market on macroeconomic indicators using econometric methods were examined. Positive definite distributions criterion in terms of analytic functions was obtained. The asymptotic distributions of the sequences of integer-valued additive functions defined on the symmetric group endowed with the Ewens probability measure as the order of the group increases were explored. It was proven that the a-points of the Selberg zeta-function are distributed uniformly modulo one.

International Research Projects

COST action: Mathematical Optimization in the Decision Support Systems for Efficient and Robust Energy NetworksTD1207 Member of Managing Committee.  Prof. Dr. J. Žilinskas. 2013–2017, http://www.cost.eu/domains_actions/ict/Actions./TD1207?management.

Energy Production and Distribution (EP&D) is among the biggest challenges of our time, since energy is a scarce resource whose efficient production and fair distribution is associated with many technical, economical, political and ethical issues like environmental protection and people health. EP&D networks have rapidly increased their size and complexity, e.g. with the introduction and interconnection of markets within the EU. Thus, there is an increasing need of systems supporting the operational, regulatory and design decisions through a highly inter-disciplinary approach, where experts of all the concerned fields contribute to the definition of appropriate mathematical models. This is particularly challenging because these models require the simultaneous use of many different mathematical optimization tools and the verification by experts of the underlying engineering and financial issues.

COST action: Onetwork for Sustainable Ultrascale Computing (NESUS) IC1305 Member of Managing Committee Dr. A. Lančinskas. 2014–2018, http://www.cost.eu/COST_Actions/ict/Actions/IC1305.

Ultrascale systems are envisioned as large-scale complex systems joining parallel and distributed computing systems that will be two to three orders of magnitude larger that today's systems. The EU is already funding large scale computing systems research, but it is not coordinated across researchers, leading to duplications and inefficiencies. The goal of the NESUS Action is to establish an open European research network targeting sustainable solutions for ultrascale computing aiming at cross fertilization among HPC, large scale distributed systems, and big data management. The network will contribute to glue disparate researchers working across different areas and provide a meeting ground for researchers in these separate areas to exchange ideas, to identify synergies, and to pursue common activities in research topics such as sustainable software solutions (applications and system software stack), data management, energy efficiency, and resilience. Some of the most active research groups of the world in this area are members of this proposal. This Action will increase the value of these groups at the European-level by reducing duplication of efforts and providing a more holistic view to all researchers, it will promote the leadership of Europe, and it will increase their impact on science, economy, and society.

It was proposed how to integrate information software systems requirements that were specified on the basis of different stakeholders views and attitudes.
The methods that enable to adapt heterogeneous e-services for special user’s needs were created. The service-oriented decision support system architecture was proposed which integrate knowledge base, reasoning rules, and situation recognition rules by using wireless technology solutions.

 Nonlinear Long Memory, Heavy Tails and Aggregation (no. MIP-063/2013). Prof. D. Surgailis. 2013–2015.

We discuss joint temporal and contemporaneous aggregation of N independent copies of random-coefficient AR(1) process when N and time scale n increase at different rate. Assuming that the coefficient has a probability density, regularly varying at the unit root with exponent -1<β<1, different joint limits of normalized aggregated partial sums are shown to exist when N^{1/(1+β)}/n tends to (i) ∞, (ii) 0, (iii) 0<µ<∞. The intermediate process arising under (iii) is studied in detail.

Optimal Solutions in Data Mining Tasks. Prof. Habil. Dr. G. Dzemyda. 2014–2016.

The volumes and diversity of data are rapidly increasing in our days. Optimization, visualization and simulation methods for specific data (biomedical, financial, visual etc.) help us to analyze and take decisions. However there is a need to get new knowledge from existing data. Therefore it is necessary to develop new hybrid data mining and optimization methods that can help you to find and reveal an important new knowledge. Parallel computing is also an important tool for these challenges.
New genetic algorithm for solving vehicle routing problems has been developed and investigated; new genetic algorithm for solving vehicle routing problems has been developed and investigated; efficient optimization algorithms are theoretically substantiated in the case of „expensive“, „black box“ objective functions; efficiency of the use of the geodesic distances in the intrinsic dimensionality estimation of the data using packing numbers is investigated.

Study and Application of Statistical Simulation and Stochastic Programming to Computer Network Design. Prof. Dr. Habil. L. Sakalauskas. 2013–2015.

The stochastic algorithm for association rules discovery in large data sets, which has many applications in warehousing, has been developed. The algorithm gives conclusions about association rules using analysis of randomly selected subsequences. The developed algorithm was tested by computer modelingalgorithm
The issues of analysis of queueing systems, arising in the network theory and communications theory, called multiphase queueing systems, tandem queues or series of queueing systems, have been studied. The multiphase queueing systems can be useful for modelling practical multi-stage service systems in a variety of disciplines, especially on manufacturing, computer networking, and in telecommunications, etc. The research presented heavy traffic limit theorems for the cumulative idle time in multiphase queues. In this work, functional limit theorems are proved for the values of important probability characteristics of the queueing system.

Research Council of Lithuania. Identification of Epigenetic Markers for Early Diagnosis of Colorectal Cancer (No. MIP-043/2014) Dr. J. Gordevičius. 20142016.

In this project we propose to perform data analysis of epigenetic profiles in blood circulating DNA to detect epigenetic biomarkers for early CRC diagnosis. Our goal is to apply novel algorithmic methods that will reveal epigenetic aberrations in extended regions when comparing cancer patients to controls. The detected regions will be used to train machine learning algorithms and to build and evaluate an early diagnostic CRC classifier. The bioinformatics analysis conducted in this project may provide novel, non-invasive markers, with the potential for translation into clinical practice.
