No full textGennady Filippovich Matveev (born in 1943), Doctor of Historical Sciences, Honored Professor of Moscow University, Head of the Department of the History of the Southern and Western Slavs of Moscow State University, one of the leading domestic specialists in the modern history of Poland, tells about his life and professional activities at the request of the editors of the journal Slavic World in the Third Millennium. Born on the banks of the Volga, G.F. Matveev spent his childhood and youth in Western Ukraine. Since 1966, his whole life has been inextricably linked with the Moscow University, where he received a diploma in history, completed his postgraduate studies, defended his candidate's and doctoral theses, and where he has been teaching for half a century and was head of the department for more than three decades. The students of G.F. Matveev completed and defended a large number of diplomas, master's and candidate's theses, they work in different cities of the country and abroad. As a historian, G.F. Matveev invariably relies on deep researches in archives, introduces a lot of new material into circulation, his innovative research on the history of the Soviet-Polish war of 1920 caused fruitful discussions both in Russia and in Poland, prompting other historians to further research. Gennady Filippovich is the author of the first fundamental biography in Russian of the key statesman of Poland of the 20th century Józef Piƚsudski. Not limited to the problems of Polish history, G.F. Matveev turned to comparative historical research on the material of various Slavic countries, in particular, on the ideology of peasant movements in the period between the two world wars. As an author and editor, he took part in the work on textbooks on the history of the southern and western Slavs. For more than half a century, G.F. Matveev maintains close ties with the Institute of Slavic Studies of the Russian Academy of Sciences, he is a member of the editorial boards of historical journals, both Russian and Polish.
G.F. Matveev talks about his post-war childhood, youth, impressions of his student years, about his work at the Moscow University, about his numerous trips to Poland and more than half a century of communication with Polish colleagues. He also shares his opinion on the current development and prospects of Polish studies in Russia, the possibilities for further dialogue between the two cultures

Interactive Photo Liveness for Presentation Attacks Detection
No full textThis paper presents an interactive liveness detection approach
against presentation attacks. It aims to minimize the impact on the
user, who is only asked to produce single head movements. The described
approach combines two methods: (1) single-photo liveness estimation
based on CNN implementation, and (2) interactive liveness estimation
based on head movements detected from two video frames extracted
before and during the movement. The resulting system is designed to
work on smartphones and by web-cameras. An appropriate database was
collected for experiments. These achieved EER of less than 5% for paper
spoofing attacks, less than 4% for monitor and 0.6% for tablet, while the
Failure to Capture (FTC) was less than 3% for the most user-friendly
scenario
Transfer of a work by e-mail: copyright aspect
No full textE-mail gives the opportunity to send a work of science, literature and art to one or more addressees. Russian copyright law does not allow us to make an unambiguous conclusion about the legitimacy of such use of a work. Purpose: to determine the legal regime of the transfer of works protected by copyright through e-mail. Methods: method of formal logic, systematic structural and formal dogmatic methods are used in the analysis. The article presents two approaches to the problem under consideration. Article 1270 of the Civil Code of the Russian Federation is devoted to the contents of the exclusive copyright. This article establishes an open list of methods to use a work. Accordingly, we can make a logically correct, but legally dubious conclusion that any emailing of a work is illegal. This logic is based on the questionable legal technique of art. 1270 of the Civil Code of the Russian Federation. The author of the paper believes that the second approach is correct. According to this approach, the content of exclusive copyright should be limited to the methods to use a work that is specified in art. 1270. Emailing of a work includes two legally significant actions with such a work: 1) the creation of an electronic copy of a work; 2) sending this copy via the information and telecommunications network as an electronic message to a specific address. The first action is the reproduction of a work. The second action is the communication to the public. The transfer of a work by e-mail is the communication to the public if access to such a work can be obtained by a significant number of persons who do not belong to the usual family circle
Robust speech recognition for low-resource languages
No full textProcess of human-machine interaction is an integral part of everyday human life in a modern world. The various interfaces are intended to facilitate this interaction and provide maximum comfort for users. The speech interface is the most universal, and it can be used in a vast majority of systems. Speech is the main way of communication between people, from this point of view speech interface looks completely natural. Nowadays, human-machine speech interfaces can consist of many complex components in order to implement an interaction with a user. However, a primary element of such interfaces is an automatic speech recognition (ASR) system.
Automatic recognition of spontaneous speech in a telephone channel can be solved very successfully in the presence of significant amount of speech training data, but the collection and processing of such data is a complex, time-consuming and expensive task. Great amount of data is available only for high-resource languages such as English, Spanish, German, Chinese, French, etc. At the same time, there are many languages with no significant amount of training data for ASR systems preparation. Such languages are commonly referred to as low-resource languages. The number of native speakers for such languages can reach tens, and sometimes hundreds of millions of people. Taking this into account, building ASR systems for such languages is an important task.
The main objective main objective of this thesis is the development of universal methodology for robust speech recognition of low-resource languages. To achieve it, we have solved three tasks. First, we have developed a flexible methodology in order to build an ASR system for large vocabulary conversational speech on low-resource languages. Second, we have identified a set of languages representing a wide variety of acoustic and grammatical features that influence on ASR systems. Third, we have conducted experimental studies of the developed universal methodology and compared the accuracy of the resulting ASR systems with the state-of-the-art results.
We have contributed to several key components of the ASR system as part of the first task. We have proposed speaker-dependent bottleneck acoustic features trained with a multilingual approach, to improve acoustic modeling. Besides, a new approach of combining acoustic features has been proposed. In terms of language modeling, we have proposed a new method of text data augmentation with the artificial texts generated by the Char-RNN model. Finally, we have created a universal methodology that combines both existing and proposed methods. This methodology represents a complete pipeline for building ASR systems for low-resource languages.
As a part of the second task, we have identified the most important language features which affect the building process of ASR systems. We have considered such factors as word order, agglutination, inflection, presence of an accent, dialects, and tone. Based on the analysis, we have created a set of low-resource languages that covers the factors described above and several additional features. This set includes eight languages: Georgian, Turkish, Kazakh, Vietnamese, Swahili, Tagalog, Zulu, and Russian.
As a part of the third task, we have conducted large-scale experimental studies. We have identified the most effective basic acoustic features and the training pipeline for initial GMM-HMM models. We have verified proposed multilingual speaker-dependent bottleneck features and confirmed the effectiveness of the delayed combination for acoustic features. We have determined the usefulness of the proposed text data augmentation approach. Moreover, we have found this approach complementary to the addition of filtered web-text data. We have experimented with various neural network-based acoustic models and identified the most effective ones. Finally, we have compared the accuracy of resulting ASR systems with the state-of-the-art results for studied low-resource languages.
We believe that this work will accelerate further research of speech recognition in low-resource languages and make speech recognition systems available for a wide variety of world languages in the near future.Diese Dissertation entstand im Rahmen einer Kooperation mit der Universität ITMO in St. Petersburg. / This dissertation was written in the context of a cooperation with ITMO University in St. Petersburg
A small-gain-theorem-like approach to nonlinear observability via finite capacity channels
No full textThe paper is concerned with observation of discrete-time, nonlinear, deterministic, and maybe chaotic systems via communication channels with finite data rates, with a focus on minimum data-rates needed for various types of observability. With the objective of developing tractable techniques to estimate these rates, the paper discloses benefits from regard to the operational structure of the system in the case where the system is representable as a feedback interconnection of two subsystems with inputs and outputs. To this end, a novel estimation method is elaborated, which is alike in flavor to the celebrated small gain theorem on input-to-output stability. The utility of this approach is demonstrated for general nonlinear time-delay systems by rigorously justifying an experimentally discovered phenomenon: Their topological entropy stays bounded as the delay grows without limits. This is extended on the studied observability rates and appended by constructive finite upper bounds independent of the delay. It is shown that these bounds are asymptotically tight for a time-delay analog of the bouncing ball dynamics. Team Tamas Keviczk

The meeting of a Russian with Europe in the travel writings of Peter the Great’s era (A. A. Matveev)
No full textThe paper revises the traditional view at the travel writings of the era of Peter the Great. They
are usually considered as naive works, and content of these works as identical to the biographies
of it’s authors. The method of historical and linguistic research of V. M. Zhivov on the
language of Russian writing is applied to the material of travelogues. The main purpose is to
account for the pragmatics of the utterance in travel literature as in a phenomenon synthesizing
heterogeneous features in principle and in the transitional Peter’s Era in particular. The
paper is focused on the notes of the diplomat A. A. Matveev, compiled by him for himself as
a result of his journey from the Hague to Paris (1705–1706). The narrative technique in Matveev’s
text is examined (descriptions of the monuments of the French capital and the inscriptions
to them in Latin), and it is shown that we should not reduce the function of Matveev’s
work to purely diplomatic tasks of his actual journey. The descriptions recorded in Matveev’s
text were politically charged: the author not only collected samples of inscriptions, but also
demonstrated a new way for Russia to glorify the reigning monarch. This peculiar collection
of Matveev is also considered in the context of cultural phenomena that were relevant at the
beginning of the 18th century: private and court collections of rarities, embossing of commemorative
medals, etc. The conclusion is made that borrowed elements change their function
in the travelogue. In the historical and literary perspective, we must bring such works as
Matveev’s notes out of the zone of marginal literary phenomena. In general, this allows us to
see the key trends of the transitional period of the history of Russian literature. It is more appropriate
to consider these processes not to state the Western European origin of individual
elements of culture, but to analyze their pragmatics associated with the demarcation from the
old Russian culture.The study was funded by the Russian Science Foundation, project no. 21-18-00527 in the Institute of
Russian Literature (Pushkin House) of the Russian Academy of Sciences, https://rscf.ru/project/21-18-00527/
