Statistical Properties of Complex Random Systems. Prof. V. Bentkus (until June 03, 2010),  Prof. J. K. Sunklodas,  Prof. M. Radavi膷ius (since June 03, 2010). 2010鈥2012.

The new representations for Tweedie EDMs as well as several new concepts and technical assertions were investigated. The general asymptotic formula for the probabilities of high excursions of differentiable Gaussian fields was proved. The optimal estimates of smooth metrics in the central limit theorem have been obtained for random sums of independent nonidentically distributed random variables. The problem of estimation of the tail index in the case where max-aggregated random variables are observed. Strongly consistent and asymptotic normal estimators of the Hurst index of stochastic differential equation driven by a fractional Brownian motion are proposed. A total variation approximation for the distribution of component vector of a weakly logarithmic random assembly is obtained. Necessary and sufficient conditions for a generalized function to be a positive definite distribution were investigated. For sparse contingency tables, nonparametric tests have been constructed and their consistency in the general setting of sparse asymptotics has been proved.  Statistical properties of finite-population statistics were considered.

Decisions in Optimization, Modeling and Visualization Problems. Prof. G. Dzemyda. 2011鈥2013.

Algorithms for multidimensional data visualization, based on self-organizing maps, are developed. An approach is proposed for the analysis of the online shopping data by integrating multidimensional data visualization methods of different nature.
The local binarization method is modified for automatic detection of blood vessels in retinal images. The Pareto-Lipschitzian algorithm is developed and investigated.
An algorithm is proposed for the uniform representation of the Pareto set of a multi-objective optimization problem.
Inequality in multiserver open queueing networks for queue length of jobs and virtual waiting time of job in heavy traffic conditions is proved.
Approximation of the Transmission Disequilibrium Test using Poisson distribution for family based data is developed.
Comparative analysis of classification methods (C.4.5, kNN, SVM, Na茂ve Bayes) is accomplished in order to identify most accurate method for data of patients.
Limit theorems for coefficients of a modified Borwein method are proved, and parallel version the algorithm for the calculation of the Riemann zeta-function is implemented and scrutinized on the IBM-SP6 cluster.
The Risk Aversion problem, often arising in credit and portfolio applications, has considered as a framework of nonlinear stochastic programming with constraints on CVAR of financial instruments. The method of sequential quadratic programming is developed to solve the risk aversion optimization problem by series of Monte-Carlo estimators. The approach considered distinctions by adaptive regulation of the Monte-Carlo sample size, which ensures convergence with linear rate, and statistical manner for termination of the algorithm.
The numerical issues of empirical Bayesian (EB) approach model, applied to estimation of small rates have been considered. The properties of EB model have been investigated and compared by Monte-Carlo method. The approach developed has been tested with real statistical data of Lithuanian population.

Methods and Technologies to Specify, Model, and Develop Services-Oriented Software Systems. Prof. A. 膶aplinskas (leader), D. Drungilas, Prof. D. Dzemydien臈, R. Dzindzalieta, D. Drungilas, G. Gricius, M. Kurmis, Doc. A. Lupeikien臈, J. Miliauskait臈, A. Miliauskas, Dr. S. Maskeli奴nas, L. Paliulionien臈, Dr. V. Paliulionis, S. Svanidzait臈, M. 艩au膷i奴nas. 2012鈥2014.

It has been proposed how to improve J.Lin鈥檚 conceptual model in order to integrate service discovery, contracting, and trustworth negotiation tools. Current methods to predict and classify the service composition properties have been investigated and generalized. The characteristics of the most important SOA (service-oriented architecture) systems development process components have been identified, classified, and generalized. A model of an adaptive system supporting desicion making in dynamic domains has been created. The model allows the system to improve the quality of services on the basis of feedback information. A multi-layered architecture of a decision support system for monitoring of dangerous good transportation has been developed.

Construction of Deductive Systems for Non-Classical Logics; Evaluation of Lower Bounds for Algorithmic Paradigms.  Habil. Dr.  R. Pliu拧kevi膷ius (Leader), Dr. R. Alonderis, Habil. Dr. S. Jukna, Dr. J. Sakalauskait臈, A. Gir膷ys, H. Giedra. 2012鈥2014.

The scientific research was realized in two areas: (1) construction of cut rule free and terminating sequent calculi for non-classical logics; (2) proving lower bounds for cutting plane and dynamic programming algorithms.
In the first area, the following problems have been investigated:
(a) elimination of the invariant rule from a sequent calculus for propositional linear tense logic (PLTL); (b) cut elimination from sequent calculi for multimodal logic of correlated logic. Concerning point (a), the invariant and cut rules free sequent calculus for PLTL is constructed; the calculus is proved to be sound and complete for a fragment of the logic. Concerning point (b), sequent calculi without cut rule for combinations is constructed.
In the second area, it is proved that polynomial-time cutting plane algorithms cannot approximate the clique problem by any nontrivial factor. A surprisingly efficient communication protocol for the biclique problem is found, showing that communication complexity arguments cannot lead to strong lower bounds for cutting plane algorithms solving this problem. A matching lower bound on the number of subproblems in any incremental dynamic programming algorithm for the Knapsack problem is also proved.

Investigation of Fractal Properties of Random Proceses and Random Fields. R. Norvai拧a, D. Surgailis. 2012鈥2013.

A new nonparametric estimator of the local Hurst function of a multifractional Gaussian process based on the increment ratio (IR) statistic is defined. In a general frame, the point-wise and uniform weak and strong consistency and a multidimensional central limit theorem for this estimator are established. Similar results are obtained for a refinement of the generalized quadratic variations (QV) estimator. The example of the multifractional Brownian motion is studied in detail. A simulation study is included showing that the IR-estimator is more accurate than the QV-estimator.
