Автоматическое построение фонетической транскрипции речи на основе принципа минимума информационного рассогласования
Studied is a possibility of increasing the accuracy of diagnostics by examining a number of diagnostic rules as a set of expert assessments, which allows one to combine them («mix of expert opinions»). Proposed is to use of the principle of minimum-information-mismatch in Kullback - Leibler metric to highlight the rule most appropriate for classification of a particular object. Program and results of experimental study are presented in the problem of automatic recognition of gray-scale images. It is shown that the developed approach can significantly improve the quality of diagnostics.
This research studies the influence of professional competence of EFL learners on their metaphor production. The task was approached through analyzing metaphors in the English written texts produced by Russian students with different competence in economics – the non-professional and professional competence level. Findings highlight similarities and divergence of metaphor use in L2 writing in terms of learners’ professional competence. The results of comparative analysis of specific features in metaphors produced at different professional competence levels reveal the quantitative and qualitative differences of what functions metaphors are used to perform and to what extent they are used accurately. With the shift from the non-professional to the professional competence level learners are able to use metaphors that combine a function of presenting abstract concepts with a discourse organising function in a more balanced way and make much more use of creative metaphors, and their metaphor production tends to be less influenced by L1 background. Practical recommendations suggest an improved research methodology for studying metaphor production in ESAP as well as a deeper understanding of ESP content and its structure.
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
A form for an unbiased estimate of the coefficient of determination of a linear regression model is obtained. It is calculated by using a sample from a multivariate normal distribution. This estimate is proposed as an alternative criterion for a choice of regression factors.
