Expressiveness and Decidability of Weighted Automata and Weighted Logics
… line of development, Schützenberger introduced weighted automata which allow the description of quantitative properties of regular languages. In subsequent works, many of these descriptive formalisms and extensions were combined and their relationships investigated. For example, weighted regular …

Heuristic Weighted Voting
… this issue, we present the strategy of Heuristic Weighted Voting, a technique that uses heuristics to determine the confidence that a classifier has in its predictions on an instance by instance basis. Using these heuristics to weight the votes in an ensemble results in an overall average increase …

Weighted Consecutive Ones Problems
… ones property. The latter problem is called Weighted (Simultaneous) Consecutive Ones Problem WC1P (WSC1P). In this thesis we study both the WC1P and the WSC1P from a polyhedral point of view and derive integer programming formulations consisting only of facets of the corresponding polytopes. …

Weighted Logics and Weighted Simple Automata for Context-Free Languages of Infinite Words
… recently developed for infinite nested words. In weighted automata theory, many classical results on formal languages have been extended into a quantitative setting. Weighted context-free languages of finite words trace back already to Chomsky and Schützenberger. Their work has been extended to …

Weighted Optimality of Block Designs
… This dissertation develops a general theory of weighted design optimality, with special attention to the block design problem. Among others, this study develops and justifies weighted versions of the popular A, E and MV optimality criteria. These are based on the weighted information matrix, …

A class of weighted Bergman spaces, reducing subspaces for multiple weighted shifts, and dilatable operators
… In Chapter 2 we will introduce a class of weighted Bergman spaces. We then will discuss some properties about the multiplication operator, Mz , on them. We also characterize the dual spaces of these weighted Bergman spaces. In Chapter 3 we will characterize the reducing subspaces of …

A Combinatorial View of Weighted Voting
Given a chain of the partially ordered set of weighted games, it is currently unknown if weights can be assigned to each of the $n$ voters so that the chain is weighted. We conjecture that every consistent chain $C$ through weighted games admits weights, $\vec{w}$, such that for all weighted games …

On stochastic completeness of weighted graphs
In this thesis we are concerned with the long time behavior of continuous time random walks on infinite graphs. The following three related problems are considered. 1. Stochastic completeness of the random walk. We characterize the stochastic completeness of the random walk in terms of …

Sparse technology in weighted harmonic analysis
… for sparse operators. Secondly, we prove several weighted estimates for bilinear fractional integral operators and their commutators with BMO functions. We also prove a maximal function control theorem for these operators, that is, we prove that the weighted $L^p$ norm is bounded by the weighted …

Search in weighted constraint satisfaction problems
… optimisation problems can be modelled as Weighted Constraint Satisfaction Problems (WCSPs). Such problems are NP-hard and require an exponential amount of time to find the optimal solution. This thesis concentrates on the University Examination Timetabling Problem. A general abstraction of …

Statistical algorithms for Cluster Weighted Models
Cluster-weighted modeling (CWM) is a mixture approach to modeling the joint probability of data coming from a heterogeneous population. In this thesis first we investigate statistical properties of CWM from both theoretical and numerical point of view for both Gaussian and Student-t CWM. Then we …

Weighted Graph Compression using Genetic Algorithms
… lost during the compression process. Unweighted graphs are largely studied in this area. However, in this thesis, we extend the approaches to compress weighted graphs via genetic algorithms and analyse the compression from an epidemic point of view. It is seen that edge weights provide …

Hardware IP Classification through Weighted Characteristics
… a percent match within each characteristic. A weighted average of these percent matches makes up the final percentage. If the library entry with the best match is known to have a Trojan inserted, then the unknown design is likely to have a Trojan as well and vice versa. Due to the structural …

Combinatorial enumeration of weighted Catalan numbers
… is devoted to the divisibility property of weighted Catalan and Motzkin numbers and its applications. In Chapter 1, the definitions and properties of weighted Catalan and Motzkin numbers are introduced. Chapter 2 studies Wilf conjecture on the complementary Bell number, the alternating sum …

General Weighted Optimality of Designed Experiments
… They were then able to generate a broad class of weighted optimality criteria that evaluate a design's ability to maximize the weighted information, ultimately targeting those designs that efficiently estimate effects assigned larger weight. This dissertation considers a much broader class of …

Reconstructing the Ancient Greek Warp Weighted Loom
Penelope, Arachne, and Athena: all are prominent female figures in Greek mythology who are known for their magnificent weaving skills. Indeed, the Greeks took pride from the skills that their daughters and wives exhibited on the loom because of the economic and social importance of weaving. Modern …

Weighted estimates for dyadic operators with complexity
