There are a very large number of generalizations and analogues of this theorem. Here we will mention only some results where the conditions on F exclude certain configurations which can be expressed by inclusion only ∗School of Mathematics, Georgia Institute of Technology, Atlanta GA †The second author was supported by the Hungarian National Foundation for Scientific Research grant numbers NK06...

Web page ranking and collaborative filtering require the optimization of sophisticated performance measures. Current Support Vector approaches are unable to optimize them directly and focus on pairwise comparisons instead. We present a new approach which allows direct optimization of the relevant loss functions. This is achieved via structured estimation in Hilbert spaces. It is most related to...

Objectives: The Hospital Anxiety and Depression Scale (HADS) is a widely used screening instrument. The purpose of this study was to evaluate reliability and validity of the Hungarian translation. Methods: The English version of the HADS was translated using the 'forward-backward' procedure. The questionnaire was used in a large scale study of 678 Hungarian cancer patients along with other scre...

Hungarian paleostomatology as the part of dental anthropology exists since the middle of the last century, together with the paleodontical research in the world. The name paleostomatology comes from a Hungarian scientist, György Huszár. The article has the following chapters: Introduction (what is paleostomatology, and its importance), First studies in the world, Nomenclature, The bases of Hung...

Background The Hungarian draft is a horse breed with a recent mixed ancestry created in the 1920s by crossing local mares with draught horses imported from France and Belgium. The interest in its conservation and characterization has increased over the last few years. The aim of this work is to contribute to the characterization of the endangered Hungarian heavy draft horse populations in order...

A linear programming (LP) approach is proposed for the weighted graph matching problem. A linear program is obtained by formulating the graph matching problem in L1 norm and then transforming the resulting quadratic optimization problem to a linear one. The linear program is solved using a Simplex-based algorithm. Then, approximate 0-1 integer solutions are obtained by applying the Hungarian me...

In this paper, a novel approach to solve the permutation indeterminacy in the separation of convolved mixtures in frequency domain is proposed. A fixed-point algorithm in complex domain is used to separate the signals in each frequency bin. These are obtained applying a Short Time Fourier Transform on a set of fixed frames. To solve the ambiguity of the amplitude dilation, a simple method is pr...

We describe our official runs for the ad hoc monolingual task in Hungarian for CLEF 2005. We conducted experiments with four stemmers of varying impact. The experiments indicate that stemmers focusing on noun inflection are as effective as more broadly oriented stemmers, and that extensive stemming is especially beneficial for Hungarian monolingual retrieval.

Prescriptive and descriptive grammars of Hungarian frequently discuss variation in the choice of relative pronoun in Hungarian. This paper presents quantitative data about some long standing questions raised by prescriptivists, and a phenomenon that has not been explored: the lack of agreement between the pronoun and the antecedent in Colloquial Hungarian. The study presented here is based on t...

Background and aim: Complementary and Alternative Medicine (CAM), as utilized by European citizens, represents a variety of different medical systems and therapies based on the knowledge, skills and practices derived from theories, philosophies and experiences used to maintain and improve health, as well as to prevent, diagnose, relieve or treat physical and mental illnesses. The purpose of the...
