On Independent Component Analysis and Supervised Dimension Reduction for Time Series
(Turun yliopisto, 2018-02-02)
The main goal of this thesis work has been to develop tools to recover hidden structures, latent variables, or latent subspaces for multivariate and dependent time series data. The secondary goal has been to write ...
Similarity Relations on Words: Relational Codes and Periods
(Turku Centre for Computer Science, 2008-02-22)
Combinatorics on Words. New Aspects on Avoidability, Defect Effect, Equations and Palindromes
(Turku Centre for Computer Science, 2014-04-11)
In this thesis we examine four well-known and traditional concepts of combinatorics on words. However the contexts in which these topics are treated are not the traditional ones. More precisely, the question of avoidability ...
On Identifying and Locating-Dominating Codes in the Infinite King Grid
(Turku Centre for Computer Science, 2012-12-13)
On the computation of the class numbers of real Abelian fields
(Turku Centre for Computer Science, 2007-05-18)
Structural and Computational Existence Results for Multidimensional Subshifts
(Turku Centre for Computer Science, 2015-07-31)
Symbolic dynamics is a branch of mathematics that studies the structure of inﬁnite sequences of symbols, or in the multidimensional case, inﬁnite grids of symbols. Classes of such sequences and grids deﬁned by collections ...
On Hyperbolic Type Metrics
(Suomalainen tiedeakatemia, 2009-03-20)
Efficient Optimization Algorithms for Nonlinear Data Analysis
(Turku Centre for Computer Science, 2014-12-05)
Identification of low-dimensional structures and main sources of variation from multivariate data are fundamental tasks in data analysis. Many methods aimed at these tasks involve solution of an optimization problem. Thus, ...
On Undecidable Dynamical Properties of Reversible One-Dimensional Cellular Automata
(Turku Centre for Computer Science, 2010-10-29)
Cellular automata are models for massively parallel computation. A cellular automaton consists of cells which are arranged in some kind of regular lattice and a local update rule which updates the state of each cell according ...
On The Mean Square of Quadratic Dirichlet L-Functions at 1
