Parameter rollback averaged stochastic gradient descent for language model
Authors: Cheng Zhao , Chen Guanlin , Weng Wenyong , Lu Qi , Yang Wujian
Published: August 2022

Recently, AWD-LSTM (ASGD Weight-Dropped LSTM) has achieved good result in the language model, and many AWD-LSTM based models have obtained state-of-the-art perplexities. However, in fact, large-scale neural language models have been shown to be prone to overfitting. In AWD-LSTM original paper, the author decided to adopt the way of retraining calling finetune to get a better result. In this paper, we present a simple yet effective parameter rollback mechanism for neural language models. And we introduce the parameter rollback averaged stochastic gradient descent (PR-ASGD), wherein the parameter “step” in ASGD will decrease according to a certain probability. Using this strategy, we achieve better word level perplexities on Penn Treebank: 56.26 based on AWD-LSTM model and 53.57 based on AWD-LSTM-MoS (AWD-LSTM Mixture of Softmaxes) model.

Published: August 2022

The Internet of Things has a large number of terminal devices and a wide range of deployment. This feature has higher requirements for reliable transmission and parallel connection, and is more prone to network congestion resulting in the loss of power information flow and excessive delay. The traditional congestion control algorithm is not suitable for the high concurrent mass heterogeneous iot terminal access control and mass information flow storage control. In this paper, the Transformer BBR algorithm is proposed, which is a congestion control algorithm based on BBR deep reinforcement learning combined with Transformer’s excellent long-term prediction ability. In the BBR algorithm bandwidth detection stage, transformer model is used as an agent to detect the network state and map it to the congestion window, so as to find the network changing state in time and make the corresponding decision action. Firstly, the congestion control strategy is learned in the simulation network environment, and then the efficiency is verified in the simulation environment. Finally, the experiment shows that the algorithm can reduce the delay while ensuring good bandwidth performance, and is superior to the main application algorithms in network throughput.

Published: August 2022

Library is an important part of the public cultural service system. Library policy is a major force that can not be ignored. As the carrier of cultural inheritance, library plays an important role in cultivating and practicing core values and promoting civilized practice in the new era. Excavating the theme of the library is the basis for determining the development and service direction of the library. The library policy is facing difficulties such as unclear construction direction and inadequate guidance. Under this background, the research on China’s library policy is carried out. With the library as an example, the topic mining and quantitative analysis of library policies in the eastern, central, and western regions of my country from 2011 to 2020 were conducted using the LDA topic model. Meanwhile, the differences between the three regions were investigated. The results demonstrate that: (1) In terms of quantity, policy texts in the eastern region account for more than half of them; (2) Regarding keywords, high-frequency words mainly include culture, openness, and information in the eastern region, numbers, resources, and reading in the central region, and students, teaching, and learning in the western region; (3) The hot topics in the eastern region involve library government affairs, library digital resources, and library service mode, that is, strengthening the construction of library digital resources and improving service level with an open attitude; (4) The hot topics in the central region contain library management, library student training, and library security, suggesting that the aspects of internal management and system security are emphasized to train students and guide the modernization of the library; (5) The hot topic in the western region includes the construction of two libraries in one station for library evaluation management and library procurement, implying to promote library reform from the bottom up and make crucial arrangements for creating a new situation for grass-roots libraries. On this basis, the policy support of government departments for library development in the future should focus on formulating regulations and rules under the Library Law, establishing a dynamic balance between supply and demand, and enhancing exchanges and cooperation between libraries in the east, middle, and west.
Speech denoising algorithm and artificial intelligence application in network security
Authors: Wang Lei
Published: August 2022

Speech denoising refers to people finding useful information in noise-affected speech data and processing it. This technology is an important part of speech signal processing technology. With the continuous progress of science and technology, its application in various fields is gradually improving, among which voice noise reduction technology has also been well developed. Especially in recent years, with the rapid development of artificial intelligence science and technology, anti-network speech denoising technology based on deep learning has been derived. Compared with traditional speech denoising techniques, it has better performance in resolving speech data distortion and denoising results. However, in practical applications, this method still has some shortcomings, such as: some unique noises are not removed, and the effective information extraction is distorted under the background of high-intensity noise. In response to these outstanding problems, this research is based on the anti-network speech denoising technology, combined with the Wiener filter speech denoising algorithm, and applies artificial intelligence technology to network security technology management. In this paper, two algorithms, COVL and SSNR, are used to compare the original input speech data signal with noise and the speech data signal preprocessed by Wiener filtering. The additional information is input into the generation network and the discriminant network, and the additional information is used to guide the data generation. The least squares loss function of the binary coding algorithm is used to replace the cross entropy loss function, so that the original discriminant network loss function is not changed, which improves the accuracy of discrimination. This improved technology is superior in terms of speed, productivity and improved accuracy. While building the system, mature network technologies and equipment applications are fully applied, and speech de-noising technology is used for network security situation assessment and prediction simulation tests. The simulation test results show that the network security situation assessment is reasonable and effective, and the prediction is accurate in real time.

Authors: Zhang Xingmei , Yang Datian
Published: August 2022

In order to investigate the fatigue failure of compacted asphalt mixtures, the static creep mechanical behavior of aggregate-asphalt interfaces was conducted which especially constructed the creep equation between the deformation-time of aggregate-asphalt interfaces. The hard sandstone cylinder specimens of 38 mm and 21 mm in diameter were used to measure the static creep and strength of aggregate-asphalt, respectively. Through the gravity of asphalt itself, the excess asphalt flowed away from the end face of samples. A thin layer film was adhered to the end surface of hard sandstone cylinder samples. Shear strength and direct tensile strength between the aggregate-asphalt interfaces were measured with the electronic universal testing machine (EUTM) at the loading velocity of 50 mm/min and at 15∘C and 25∘C, respectively. The shear creep between the aggregate-asphalt interfaces was firstly done with EUTM successfully. The direct tensile creep was done with the universal testing machine (UTM). The shear creep deformation-time of the aggregate-asphalt interfaces was the power function relation. The direct tensile creep deformation-time of the aggregate-asphalt interfaces was also the power function relation. These power function relations of the aggregate-asphalt interfaces contribute to the following research about the fatigue failure of compacted asphalt mixtures.

Published: August 2022

Turbin gas merupakan salah satu penggerak mula siklus terbuka dengan bahan bakar berupa minyak bumi, gas alam ataupun campuran antara minyak bumi dan gas. Dalam perkembangannya turbin gas dapat dibuat dalam skala mikro dengan membalik prinsip turbocharger menjadi turbin gas mikro. Penelitian ini meliputi pengujian turbin gas mikro atau micro gas turbine (MGT) yaitu menggunakan 2 turbocharger yaitu 1 sebagai turbin gas penggerak kompresor (high pressure turbine) dan 1 turbine gas penggerak generator arus searah (low pressure turbine). Dalam penelitian ini menggunakan 1 ruang bakar dengan desain tertentu. Tujuan dari penelitian ini adalah membandingkan  dan meneliti hasil pengujian langsung pada mesin dan simulasi penggunaan perangkat lunak untuk memberikan gambaran fundamental tentang permodelan kinerja turbin gas mikro. Metode penelitian yang digunakan adalah menggunakan metode kuantitatif  berupa pengambilan data besaran fisik temperatur dan tekanan dengan pengujian langsung pada mesin menggunakan turbocharger DH 300-7 untuk turbin kesatu dan PC 200-8 untuk turbin kedua. Karena tumpuan poros menggunakan bantalan luncur (journal bearing) maka MGT dapat dilakukan dengan pengujian putaran turbin kesatu sebesar 16.000 rpm, pengujian kedua menggunakan putaran 20.000 rpm dan terakhir 25.000 rpm. Dalam penelitian ini hasil uji performa MGT dimasukkan dalam perangkat lunak Thermoflow, untuk memberikan gambaran fundamental tentang permodelan kinerja MGT lebih lanjut. Ditarik kesimpulan bahwa semakin tinggi putaran akan menghasilkan daya yang meningkat, tekanan dan temperatur pada sisi keluar kompresor semakin meningkat, tekanan dan temperatur pada sisi keluar dari ruang bakar semakin meningkat serta tekanan dan temperatur keluar dari turbin 1 meningkat juga temperatur keluar dari turbin 2 meningkat. Berlaku tren peningkatan tekanan pada lokasi pengamatan pada setelah keluar kompresor dan pada ruang bakar serta sedikit menurun akibat kehilangan tekanan (pressure drop) di tengah ruang bakar dan menurun setelah keluar turbin 1 dan keluar turbin 2. Tren temperatur secara umum meningkat dari keluar kompresor, ruang bakar, turbin ke 1 dan menurun sebelum masuk dan keluar turbin 2. Terjadi perbedaan antara hasil pengukururan langsung dan simulasi menggunaan perangkat lunak yaitu karena pengukuran langsung hanya mengukur kondisi fisik diluar (casing) mesin secara manual dan kondisi lingkungan yang berubah-ubah, berupa angin, kelembaban. Kondisi mesin berbeda saat pengujian 16.000 rpm mesin cenderung lebih dingin dibanding 20.000 rpm dan 25.000 rpm, kehadiran oli pendingin mesin serta desain ruang bakar. Untuk simulasi perangkat lunak menggunakan perhitungan berulang berupa iterasi menggunakan persamaan matematika secara ideal dan bersifat numerik serta kemungkinan adanya asumsi yang tidak pasti.

Published: August 2022

The article discusses the main approaches to the development and use of the task system for the first All-Russian Olympiad in artificial intelligence for schoolchildren. The first Olympiad in artificial intelligence for schoolchildren, held by the Ministry of Education of the Russian Federation, had distinctive features in the procedure of the competition and in competition tasks. These features can be used for comparative analysis and expert evaluation of intellectual competitions for schoolchildren held in Russia. The subjects of the Olympiad tasks are Natural Language Processing, Computer Vision, and Data Science.

The Python programming language was used. The tasks were focused on the formation of an individual path for the student to prepare for the final stage of the Olympiad in artificial intelligence, i. e. thematic continuity was observed at all stages and the practical orientation of tasks using data sets was observed in the second and third rounds. For the assessment, a rating assessment was used (as in the professional community Kaggle.com) of the individual abilities of schoolchildren in the complex application of mathematical and digital skills in solving artificial intelligence tasks.

The article may be useful for informatics teachers who include the topic in an advanced informatics course and teachers of additional education who prepare schoolchildren for Olympiads in programming.

Published: August 2022

The relevance of integrating massive open online courses (MOOCs) into foreign language teaching in higher education is explained not only by the modern approach to the digitalization of the educational environment, but is also a necessary measure in the light of the unfavorable epidemiological situation in Russia associated with the spread of a new coronavirus infection (COVID-19).

The classification of MOOCs by purpose, principle of construction and format of training is given. The advantages and the disadvantages of MOOCs from the point of view of teachers are considered. The results of the integration of MOOCs into foreign language teaching to students of a range of engineering specialities are presented.

Experimental work has identified the advantages of MOOCs associated with an unlimited resource base, a variety of tasks and access to authentic information.

The disadvantages of MOOCs in teaching a foreign language concern the difficulties caused by the pedagogical imperfection of the format for evaluating the work of students on the course. A number of problems are associated with the lack of the necessary competencies of teachers, resource consumption when choosing a MOOC, corresponding to the level of language training of students.

The authors propose ways to solve the problems that arise in the implementation of a mixed model of teaching a foreign language at universities, including the combination of traditional and online forms of monitoring learning outcomes.

Elements of the methodology of teaching computer 3d graphics at the level of basic general education using KOMPAS-3D LT V12
Authors: Markushevich M. V.
Published: August 2022

3D computer graphics is information technology that is not mandatory for studying at the level of basic general education. Its study is more related to pre-profile training in advanced programs used in such educational projects as the Mathematical Vertical. In this regard, there is a certain shortage of teaching methods for this topic, using Russian free or open source software as software tools.As the best software to support the teaching of the topic "3D computer graphics", it is proposed to consider both the domestic free 3D modeling system KOMPAS-3D LT V12 for non-commercial and educational purposes, and the free 3D parametric modeling system FreeCAD. The choice of KOMPAS-3D LT V12 is primarily due to the need to use domestic software in the face of constant tightening of economic sanctions against the Russian Federation by a number of unfriendly Western states. These sanctions also have a negative impact on the information infrastructure of Russian educational institutions.The author's method of teaching the topic "3D computer graphics" in basic school has the following characteristic features: it can be used both for distance learning and for full-time education; is based on domestic software, in connection with which the infrastructure of Russian educational organizations does not fall under the threat of an unmotivated refusal of licenses to use foreign proprietary software. In addition, the use of free versions of software in the educational process optimizes government spending on education.

Hypertextual construction of events: cognitive-discourse study
Authors: Kryshtaliuk Hanna
Published: August 2022

The article views hypertext as an instrument of constructing events treated as cognitive-discourse formations, giving access to the conceptualization of the world. Different in format, quality and hypertext British print digitalized newspapers The Daily Telegraph, The Daily Mail and electronic newspapers The Telegraph, The Mail Online have been used as data sources in this research. The complex cognitive-discourse methodology with the techniques of image-schematic analysis and hypertextual analysis has been applied to specify the peculiarities of hypertextual event construction on the front page of British newspapers. It has been found out that the primary function of newspaper hypertext is to distinguish events by the way of their construction. In the broadsheet edition of The Daily Telegraph, the front page hypertext provides a clear distinction between the announcement of events and their main representation. The hypertext of the main web-page of The Telegraph contains only event announcements that can be distinguished according to the genre of their construction. On the front page of the tabloids The Daily Mail and The Mail Online the distinguishing function is partly neutralized as the announcement of events and their main representation are merged and blurred.
According to the topological principle, the hypertextual patterns of announcing events on the front page of the broadsheet The Daily Telegraph and the tabloid The Daily Mail have been singled out. The conducted research has shown that the broadsheet and the tabloid differ in the amount of space on the newspaper page allocated for event announcements as well as for verbal and nonverbal components specifying event construction. Asymmetry in the verbal and nonverbal event representation increases from the quality newspaper The Daily Telegraph to the electronic tabloid The Mail Online where the nonverbal component dominates. The latter, as a rule, is used for constructing the external events, less important for the British society, whereas the verbal component is employed for representing more important internal events. The study has shown that unlike the print nonlinear newspaper hypertext, the electronic one is multilinear and gives access to a considerable number of events. It has been demonstrated that the front page newspaper hypertext constructs events of different relevance according to the coordinates UP – DOWN and LEFT – RIGHT. Resonant events appealing to the reader’s rational view are constructed in the UPPER part of the front page. Social daily events are constructed briefly from CENTER to BOTTOM of the front page and produce an emotive and evaluative reaction.
Sociocultural stereotypes in different genres of American media discourse in the middle of the last century
Authors: Liubymova Svitlana
Published: August 2022

The article provides the analysis of the means that represent sociocultural stereotypes in radio and television genres of American media discourse in the middle of the 20th century. In a cognitive-linguistic perspective, the definition of a sociocultural stereotype has been specified as a verbalized mental construct of an ethnically and culturally marked, idealized image of a person, a social group or a phenomenon. The research results prove that the analyzed sociocultural stereotypes evoke feelings to a social group or an individual, reflected in verbal and nonverbal codes. Emotional and evaluative perception of sociocultural stereotypes is dependent on the historical and cultural context. Positively evaluated stereotypes embody American cultural values. Aimed at describing the linguistic means of representation of sociocultural stereotypes, the research methodology is based on a discursive analysis and involves interpretation of media texts within the thematic and historical contexts. It has been revealed that the analyzed means that represent sociocultural stereotypes in media discourse manifest in lexical units, thematic selection of syntactic constructions, rhetorical and stylistic devices. Represented by audio-visual means in media discourse, sociocultural stereotypes are considered as complex semantic units of speech, visual, behavioral, and ethical characteristics of individuals or social groups. It has been proved that behavioral characteristics of sociocultural stereotypes are based on a speech specificity of social groups, which demonstrates their origin and social status manifested in prosodic means, lexical and grammatical forms of the utterances.

Objective: to study the heterosis and agronomic performance of raspberry F1 families derived from open-pollinated parents, and to investigate the heterotic relationships between yield and its components.

Design/methodology/approach: A total of thirty-five genotypes, including eight open-pollinated raspberry cultivars, their 28 F1 families, and one check, were evaluated for vegetative and fruit traits. The trial was carried out under a randomized block design and under open field conditions.

Results: Mid-parent heterosis ranged from -94.83 to 311.67 %, whereas the better parent heterosis values varied from -94.26 to 235.00 %. We observed that the heterosis values for yield had a strong and positive correlation (r = 0.89) with the heterosis values for number of fruits per plant.

Limitations on study/implications: heterosis and performance of F1 families in raspberry would depend on the pedigree of parents as their relativeness is a key factor to exploit the heterosis in plants.

Findings/conclusions: High values of heterosis were found in some raspberry crosses. Progeny derived from parents MU1 and TD865 showed considerable mid-parent heterosis and good performance for fruit size-related traits, soluble solids content, and yield, evidencing that both parents may be utilized as donor parents in a raspberry breeding program.

Objective: The objective of this study was to determine the water quality of the lower basin of the Usumacinta River, based on its physicochemical and microbiological characteristics. Design/methodology/approach: There were taken 11 monthly samplings of surface water during the rainy season, from June to December, 2017 and in the dry season, from April to May, 2018, in three different sites. The parameters of temperature, pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), total phosphorus (TP) and Nitrogen nitrate (N-nitrate) were evaluated. Significant statistical differences (p≤0.05) between seasons and between sites were determined. Results: The results obtained were compared with Mexican regulations and Ecological Criteria for water quality. The parameters such as EC, TDS, TSS and total phosphorus showed substantial differences among seasons. The temperature, pH, EC and N-nitrate, did not exceed the maximum permissible limits for the use of irrigation water, urban public use and protection of aquatic life. However, the presence of E. coli and total coliforms from 530 to> 24 196 MPN/100 ml was recorded throughout the study period. Findings/conclusions: Parameters under study did not show significant differences between sites. The rainy season had an important effect on the increase in concentrations of TSS, TP, N-nitrate and total coliforms. Also, that maximum concentrations were recorded during the study period in the sampling sites of Boca del Cerro (R1) and Puente Chablé (R2).

Penelitian ini bertujuan untuk mengetahui pengaruh jenis mulsa organik dan takaran kompos biochar terhadap pertumbuhan dan hasil kacang tunggak (Vigna unguiculata L. subsp. unguiculata) dalam tumpangsari di lahan kering. Penelitian ini dilaksanakan pada bulan Maret 2018 sampai bulan September 2018. Tempat pelaksanaan penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Timor, Kelurahan Sasi, Kecamatan Kota Kefamenanu, Kabupaten Timor TengahUtara. Rancangan yang digunakan dalam penelitian ini yaitu rancangan petak beralur 2 faktorial. Faktor pertama adalah mulsa organik yang terdiri dari 3 aras yaitu: tanpa mulsa, mulsa alang-alang dan mulsa jerami jagung. Faktor kedua adalah takaran pupuk kompos yang terdiri dari 4 aras yaitu: tanpa pupuk 0t/Ha 1t/Ha, 2,5 t/Ha, dan 5t/Ha. Kombinasi perlakuannya sebanyak 12unit yang diulang 3 kali sehingga terdapat 36 satuan unit percobaan. Hasil sidik ragam anova menunjukkan tidak terjadi pengaruh interaksi antara perlakuan jenis mulsa dan takaran kompos biochar terhadap parameter pertumbuhan tinggi tanaman, jumlah daun, dan diameter batang. Hasil penelitian menunjukkan bahwa pada pengamatan pertumbuhan tinggi tanaman, tanah yang diberikan perlakuan takaran kompos biochar 5 t/Ha dan jenis mulsa alang–alang memberikan hasil yang terbaik, berdasarkan hasil penelitian ini dapat disimpulkan bahwa tidak terjadinya interaksi antara perlakuan jenis mulsa dan takaran kompos biochar. Rata–rata hasil penelitian yang di dapatkan dari pengamatan pertumbuhan, takaran kompos biochar 10 t/Ha yang dikombinasikan dengan perlakuan mulsa jenis alang-alang memberikan pertumbuhan yang optimal bagi tanaman kacang tunggak.
