Sparse Matrix-Variate t Process Blockmodels
Authors: Xu Zenglin , Yan Feng , Qi Yuan
Published: September 2022

We consider the problem of modeling network interactions and identifying latent groups of network nodes. This problem is challenging due to the facts i) that the network nodes are interdependent instead of independent, ii) that the network data are very noisy (e.g., missing edges), and iii) that the network interactions are often sparse. To address these challenges, we propose a Sparse Matrix-variate t process Blockmodel (SMTB). In particular, we generalize a matrix-variate t distribution to a t process on matrices with nonlinear covariance functions. Due to this generalization, our model can estimate latent memberships for individual network nodes. This separates our model from previous t distribution based relational models. Also, we introduce sparse prior distributions on the latent membership parameters to select group assignments for individual nodes. To learn the model efficiently from data, we develop a variational method. When compared with several state-of-the-art models, including the predictive matrix-variate t models and mixed membership stochastic blockmodels, our model achieved improved prediction accuracy on real world network datasets.
Heterogeneous Transfer Learning with RBMs
Authors: Wei Bin , Pal Christopher
Published: September 2022

A common approach in machine learning is to use a large amount of labeled data to train a model. Usually this model can then only be used to classify data in the same feature space. However, labeled data is often expensive to obtain. A number of strategies have been developed by the machine learning community in recent years to address this problem, including: semi-supervised learning,domain adaptation,multi-task learning,and self-taught learning. While training data and test may have different distributions, they must remain in the same feature set. Furthermore, all the above methods work in the same feature space. In this paper, we consider an extreme case of transfer learning called heterogeneous transfer learning — where the feature spaces of the source task and the target tasks are disjoint. Previous approaches mostly fall in the multi-view learning category, where co-occurrence data from both feature spaces is required. We generalize the previous work on cross-lingual adaptation and propose a multi-task strategy for the task. We also propose the use of a restricted Boltzmann machine (RBM), a special type of probabilistic graphical models, as an implementation. We present experiments on two tasks: action recognition and cross-lingual sentiment classification.
Linear Discriminant Analysis: New Formulations and Overfit Analysis
Authors: Luo Dijun , Ding Chris , Huang Heng
Published: September 2022

In this paper, we will present a unified view for LDA. We will (1) emphasize that standard LDA solutions are not unique, (2) propose several new LDA formulations: St-orthonormal LDA, Sw-orthonormal LDA and orthogonal LDA which have unique solutions, and (3) show that with St-orthonormal LDA and Sw-orthonormal LDA formulations, solutions to all four major LDA objective functions are identical. Furthermore, we perform an indepth analysis to show that the LDA sometimes performs poorly due to over-fitting, i.e., it picks up PCA dimensions with small eigenvalues. From this analysis, we propose a stable LDA which uses PCA first to reduce to a small PCA subspace and do LDA in the subspace.
Partially Supervised Text Classification with Multi-Level Examples
Authors: Liu Tao , Du Xiaoyong , Xu Yongdong , Li Minghui , Wang Xiaolong
Published: September 2022

Partially supervised text classification has received great research attention since it only uses positive and unlabeled examples as training data. This problem can be solved by automatically labeling some negative (and more positive) examples from unlabeled examples before training a text classifier. But it is difficult to guarantee both high quality and quantity of the new labeled examples. In this paper, a multi-level example based learning method for partially supervised text classification is proposed, which can make full use of all unlabeled examples. A heuristic method is proposed to assign possible labels to unlabeled examples and partition them into multiple levels according to their labeling confidence. A text classifier is trained on these multi-level examples using weighted support vector machines. Experiments show that the multi-level example based learning method is effective for partially supervised text classification, and outperforms the existing popular methods such as Biased-SVM, ROC-SVM, S-EM and WL.
Multiagent Patrol Generalized to Complex Environmental Conditions
Authors: Agmon Noa , Urieli Daniel , Stone Peter
Published: September 2022

The problem of multiagent patrol has gained considerable attention during the past decade, with the immediate applicability of the problem being one of its main sources of interest. In this paper we concentrate on frequency-based patrol, in which the agents' goal is to optimize a frequency criterion, namely, minimizing the time between visits to a set of interest points. We consider multiagent patrol in environments with complex environmental conditions that affect the cost of traveling from one point to another. For example, in marine environments, the travel time of ships depends on parameters such as wind, water currents, and waves. We demonstrate that in such environments there is a need to consider a new multiagent patrol strategy which divides the given area into parts in which more than one agent is active, for improving frequency. We show that in general graphs this problem is intractable, therefore we focus on simplified (yet realistic) cyclic graphs with possible inner edges. Although the problem remains generally intractable in such graphs, we provide a heuristic algorithm that is shown to significantly improve point-visit frequency compared to other patrol strategies. For evaluation of our work we used a custom developed ship simulator that realistically models ship movement constraints such as engine force and drag and reaction of the ship to environmental changes.
Learning Dimensional Descent for Optimal Motion Planning in High-dimensional Spaces
Authors: Vernaza Paul , Lee Daniel
Published: September 2022

We present a novel learning-based method for generating optimal motion plans for high-dimensional motion planning problems. In order to cope with the curse of dimensional- ity, our method proceeds in a fashion similar to block co- ordinate descent in finite-dimensional optimization: at each iteration, the motion is optimized over a lower dimensional subspace while leaving the path fixed along the other dimen- sions. Naive implementations of such an idea can produce vastly suboptimal results. In this work, we show how a prof- itable set of directions in which to perform this dimensional descent procedure can be learned efficiently. We provide suf- ficient conditions for global optimality of dimensional de- scent in this learned basis, based upon the low-dimensional structure of the planning cost function. We also show how this dimensional descent procedure can easily be used for problems that do not exhibit such structure with monotonic convergence. We illustrate the application of our method to high dimensional shape planning and arm trajectory planning problems.
Online Graph Pruning for Pathfinding On Grid Maps
Authors: Harabor Daniel , Grastien Alban
Published: September 2022

Pathfinding in uniform-cost grid environments is a problem commonly found in application areas such as robotics and video games. The state-of-the-art is dominated by hierarchical pathfinding algorithms which are fast and have small memory overheads but usually return suboptimal paths. In this paper we present a novel search strategy, specific to grids, which is fast, optimal and requires no memory overhead. Our algorithm can be described as a macro operator which identifies and selectively expands only certain nodes in a grid map which we call jump points. Intermediate nodes on a path connecting two jump points are never expanded. We prove that this approach always computes optimal solutions and then undertake a thorough empirical analysis, comparing our method with related works from the literature. We find that searching with jump points can speed up A* by an order of magnitude and more and report significant improvement over the current state of the art.
Can Quadrotors Succeed as an Educational Platform?
Authors: Dodds Zachary
Published: September 2022

The flexibility and controllability of quadrotor helicopters have made them a recent focus of interest among robotics and AI research groups. At the same time, their popularity has led to a wide range of commercially available platforms, some at prices accessible for undergraduate educational use. This project evaluates the ARDrone quadrotor helicopter as a basis for use in undergraduate classes such as robotics, computer vision, or embodied AI. We have encountered both successes and frustrations in using the ARDrone to date. Looking forward, the quadrotor’s capabilities do seem a promising basis for future curricular offerings.

Dual Decomposition for Marginal Inference
Authors: Domke Justin
Published: September 2022

We present a dual decomposition approach to the tree-reweighted belief propagation objective. Each tree in the tree-reweighted bound yields one subproblem, which can be solved with the sum-product algorithm. The master problem is a simple differentiable optimization, to which a standard optimization method can be applied. Experimental results on 10x10 Ising models show the dual decomposition approach using L-BFGS is similar in settings where message-passing converges quickly, and one to two orders of magnitude faster in settings where message-passing requires many iterations, specifically high accuracy convergence, and strong interactions.
Efficient Methods for Lifted Inference with Aggregate Factors
Authors: Choi Jaesik , De Salvo Braz Rodrigo , Bui Hung
Published: September 2022

Aggregate factors (that is, those based on aggregate functions such as SUM, AVERAGE, AND etc.) in probabilistic relational models can compactly represent dependencies among a large number of relational random variables. However, propositional inference on a factor aggregating n k-valued random variables into an r-valued result random variable is O(r k 2n). Lifted methods can ameliorate this to O(r nk) in general and O(r k log n) for commutative associative aggregators. In this paper, we propose (a) an exact solution constant in n when k = 2 for certain aggregate operations such as AND, OR and SUM, and (b) a close approximation for inference with aggregate factors with time complexity constant in n. This approximate inference involves an analytical solution for some operations when k > 2. The approximation is based on the fact that the typically used aggregate functions can be represented by linear constraints in the standard (k –1)-simplex in Rk where k is the number of possible values for random variables. This includes even aggregate functions that are commutative but not associative (e.g., the MODE operator that chooses the most frequent value). Our algorithm takes polynomial time in k (which is only 2 for binary variables) regardless of r and n, and the error decreases as n increases. Therefore, for most applications (in which a close approximation suffices) our algorithm is a much more efficient solution than existing algorithms. We present experimental results supporting these claims. We also present a (c) third contribution which further optimizes aggregations over multiple groups of random variables with distinct distributions.
An Empirical Study of Bagging Predictors for Different Learning Algorithms
Authors: Liang Guohua , Zhu Xingquan , Zhang Chengqi
Published: September 2022

Bagging is a simple yet effective design which combines multiple single learners to form an ensemble for prediction. Despite its popular usage in many real-world applications, existing research is mainly concerned with studying unstable learners as the key to ensure the performance gain of a bagging predictor, with many key factors remaining unclear. For example, it is not clear when a bagging predictor can outperform a single learner and what is the expected performance gain when different learning algorithms were used to form a bagging predictor. In this paper, we carry out comprehensive empirical studies to evaluate bagging predictors by using 12 different learning algorithms and 48 benchmark data-sets. Our analysis uses robustness and stability decompositions to characterize different learning algorithms, through which we rank all learning algorithms and comparatively study their bagging predictors to draw conclusions. Our studies assert that both stability and robustness are key requirements to ensure the high performance for building a bagging predictor. In addition, our studies demonstrated that bagging is statistically superior to most single base learners, except for KNN and Naïve Bayes (NB). Multi-layer perception (MLP), Naïve Bayes Trees (NBTree), and PART are the learning algorithms with the best bagging performance.
A Bayesian Reinforcement Learning framework Using Relevant Vector Machines
Authors: Tziortziotis Nikolaos , Blekas Konstantinos
Published: September 2022

In this work we present an advanced Bayesian formulation to the task of control learning that employs the Relevance Vector Machines (RVM) generative model for value function evaluation. The key aspect of the proposed method is the design of the discount return as a generalized linear model that constitutes a well-known probabilistic approach. This allows to augment the model with advantageous sparse priors provided by the RVM's regression framework. We have also taken into account the significant issue of selecting the proper parameters of the kernel design matrix. Experiments have shown that our method produces improved performance in both simulated and real test environments.
Reconstructing the Stochastic Evolution Diagram of Dynamic Complex Systems
Authors: Bazzazzadeh Navid , Brors Benedikt , Eils Roland
Published: September 2022

The behavior and dynamics of complex systems are in focus of many research fields. The complexity of such systems comes not only from the number of their elements, but also from the unavoidable emergence of new properties of the system, which are not just a simple summation of the properties of its elements. The behavior of complex systems can be fitted with a number of well developed models, which, however, do not incorporate the modularity and the evolution of a system simultaneously. In this work, we propose a generalized model that addresses this issue. Our model is developed within the Random Set Theory’s framework and allows for reconstructing the stochastic evolution diagrams of complex systems.
Heuristic Planning in Adversarial Dynamic Domains
Authors: Chamberland Simon , Kabanza Froduald
Published: September 2022

Agents in highly dynamic adversarial domains, such as RTS games, must continually make time-critical decisions to adapt their behaviour to the changing environment. In such a context, the planning agent must consider his opponent's actions as uncontrollable, or at best influenceable. In general nondeterministic domains where there is no clear turn-taking protocol, most heuristic search methods to date do not explicitly reason about the opponent's actions when guiding the state space exploration towards goal or high-reward states. In contrast, we are investigating a domain-independent heuristic planning approach which reasons about the dynamics and uncontrollability of the opponent's behaviours in order to provide better guidance to the search process of the planner. Our planner takes as input the opponent's behaviours recognized by a plan recognition module and uses them to identify opponent's actions that lead to low-utility projected states. We believe such explicit heuristic reasoning about the potential behaviours of the opponent is crucial when planning in adversarial domains, yet is missing in today's planning approaches.
EFFECT OF MICRO-BALLOON VOLUME FRACTION ON THE TENSILE BEHAVIOR OF EPOXY SYNTACTIC FOAMS REINFORCED WITH GLASS MICRO-BALLOONS
Authors: Delavari Koorosh , Safavi Ali , Bagherzadeh Roohollah , Latifi Masoud
Published: September 2022

In this study, the effects of volume fraction on the tensile behavior of epoxy syntactic foam reinforced with glass micro-balloons are investigated. Nine different samples with various volume fractions of glass micro-balloons (0%-68%) were prepared. Elastic modulus, maximum tensile stress, and strain at failure of epoxy syntactic foams reinforced with glass micro-balloons are investigated. Scanning electron microscope (SEM) images are taken from the broken samples' surfaces and used to discuss the results. Results show that the specific elastic modulus and specific maximum tensile stress (MTS) of epoxy syntactic foams increased by about 108% and 28% by increasing the micro-balloon volume fraction from 0% to 68%. However, the samples' modulus and strength are respectively decreased by about 5% and 39% with increasing the volume fraction of the glass micro-balloons from 0% to 34%. The main growth of specific strength and elastic modulus was for samples with more than 34% micro-balloon volume fraction. Moreover, the elastic modulus increased by about 11%, and the samples' maximum tensile stress (MTS) decreased by about 32%, increasing the micro-balloon volume fraction from 0% to 68%. With increasing the micro-balloon volume fraction from 0% to 68%, the strain at failure of epoxy syntactic foams is decreased by about 41%.
Study of morphobiological features of some Gladiolus × hybridus hort. cultivars in Saratov and Perm regions
Authors:   Perm State University, Chertkova Marina A. , Shakina Tatiana N. ,   Saratov State University
Published: September 2022

The paper describes the results of a three-year study of biological characteristics of ‘Malika’, ‘Professor Parolek’, ‘Dolgozhdannyy Debut’ gladiolus cultivars on the territory of the Education and Research Center «Botanical Garden» in Saratov State University (Saratov) and the Genkel Botanical Garden in Perm State University (Perm). Plants in Saratov region experienced a detrimental effect of high summer temperatures and insufficient humidity: the height of the plant and the size of the inflorescence, the number of flowers in the inflorescence decreased. Nevertheless, the gladiolus development rate matched the biological characteristics of the cultivars in the Saratov Botanical Garden, they happened to go through the growing season before the frost and formed a mature replacement corm. In the Perm Botanical Garden, the studied cultivars also went through all the stages of growth and development, but the flowering period of the studied cultivars started later, which may be associated with a decrease in summer temperature below the optimum temperature in some years. This may have impeded the maturation of replacement corms and increased the susceptibility to fungal diseases. At the same time, the studied gladiolus cultivars retained most fully their decorative features in the Perm Botanical Garden.
Historical Past in Reflection of Urban-Oriented Network Media: New Methods of Commemoration
Authors:   Perm State University, Vlasova Elena G.
Published: September 2022

The article is devoted to the information-communicative and structural-stylistic features of the presentation of the past on the pages of urban-oriented network media that developed as an independent segment of the Russian media in the 2010s. The theoretical and methodological framework of the research is based on the studies related to the perception of commemoration as a social activity aimed at constructing cultural memory. Particular attention is given in the article to the discursive role of the media in these processes. The media are considered to be proactive mnemonic actors that not only broadcast but also create images of the historical past. Meanwhile, the choice of a commemorative strategy depends on the information policy and communicative attitudes of the particular editorial team. In urban-oriented media, topics of the historical past are included in the general agenda of a comfortable urban area, and their discursive embodiment corresponds to the orientation of these media toward active interaction with the audience. The main reference points in speculating about the past are the ideas of a personal attitude to history, joint action and the creation of a living space of memory, where the past is connected with the present in everyday urban practices. Images of the past appear in publications about life in historic houses, excursions and tours around the city, public initiatives aiming to preserve and improve the historical environment. A reliance on the monologue of the character who tells his story in the form of a self-narrative is common for such images. Contemporary engaging formats are used effectively. Humorous interactive tests, built based on publications about the unofficial history of the city, make it possible to combine entertainment with cognitive and communicative activities aimed at forming a new urban identity.
Man, World, Word in the Book by T. I. Vendina ‘Anthropology of the Dialect Word’
Authors:   Tula State Lev Tolstoy Pedagogical University, Krasovskaya Nelli A.
Published: September 2022

The remarkable monograph by T. I. Vendina Anthropology of the Dialect Word is a new one to join the ranks of numerous well-known works in linguistics that deal with the issues of anthropology and cultural linguistics. This publication is a comprehensive study that can determine the development of Russian and foreign linguistics in the field of reflection of a person, his worldview through a word for the next several decades. The essence of the book is the search for answers to the question of how a folk word, a dialect word represents a person, his system of values, reflects the main philosophical categories, the world around him. The monograph consists of chapters each of which covers a particular problem selected by the author. Each chapter is an independent and complete study, both in terms of goals and objectives defined and in terms of the selection of material and its analysis. Among the undoubted advantages of the monograph is the development of special research methods, including a ‘substrate approach’ to the analysis of a dialect word, which makes it possible to refer to the internal form and meaning of the word, as well as to reveal the spiritual principle, ethnocultural imperatives that made this internal form relevant. The monograph is distinguished by a huge amount of factual material, a large number of illustrations and examples of dialect speech, numerous classifications and internal gradations that seem valuable in themselves. Finally, the reviewed study offers a number of theoretical propositions, formulates a large number of theses that constitute its theoretical novelty and significance. It is impossible not to agree with T. I. Vendina in that dialectal vocabulary is associated with the history and culture of the people, special ways of ethical rationalization of the world are manifested in this vocabulary, it illustrates the principle of sociocentrism of language, preserves the unique philosophical worldview.

Review of Efficacy and Safety of Empagliflozin in Patients with Heart Failure
Authors:   The Pharmaceutical Society Of Korea, Lee Ha Neul , Kang Minku , Park Tae Eun
Published: September 2022

The United States (US) Food and Drug Administration (FDA) approved empagliflozin, which is a sodiumglucose cotransporter 2 (SGLT2) inhibitor used for type 2 diabetes, for the treatment of heart failure (HF) with reduced ejection fraction (HFrEF) in 2021. Earlier this year, empagliflozin became the only SGLT2 inhibitor approved for the treatment of HF with preserved ejection fraction (HFpEF) as well. These approvals were based on the studies that showed empagliflozin reducing hospitalization for HF and cardiovascular mortality. Based on these new findings, SGLT2 inhibitors, including empagliflozin, have been recently added to the heart failure treatment guidelines in the US and Europe. Although empagliflozin is approved for adults with HFrEF in South Korea, treatment guidelines for chronic heart failure have not been updated to include this drug and other SGLT2 inhibitors, yet. Therefore, the purpose of this review is to examine the studies on the efficacy and safety of empagliflozin in heart failure and its current place in clinical practice.

Published: September 2022

Here, we describe the protocol used by the Canadian Airborne Biodiversity Observatory (CABO) at Parc National du Mont Mégantic, a forested study site in southeastern Québec, to select trees for leaf-level measurements. Healthy, mature, fully sunlit leaves were harvested from permanently marked individuals distributed across the park and representing 23 species (n = 204). Harvested leaves were bulked per individual and foliar spectral reflectance measurements and a suite of foliar functional traits were quantified by the CABO foliar spectra/trait team based out of the Université de Montréal (protocol for foliar measurements described elsewhere). Additionally, height, diameter at breast height (DBH), and crown diameter were quantified for each individual. To facilitate re-location, individuals were positioned (horizontal accuracy < 2 m) and photographed. All data were collected using Fulcrum, a data collection application.

Una análisis etnográfico de los esfuerzos de la comunidad internacional para democratizar la Bosnia-Herzegovina de posguerra argumento por un gran reconocimiento de los social dentro de los aspectos técnicos de la política. En vez de las elecciones como un ritual que simbólicamente refleja o produce significados, la percepción de Bruno Latour y otros académicos de la ciencia son aplicadas a las elecciones como un sitio que crea conocimiento democrático y autoridad. Las prácticas técnicas y los objetos construyen las elecciones como un evento apolítico y acultural. Sin embargo, las formas de autoridad y relaciones sociales cradas a través de este aparentemente techne neutral son tremendamente social y político. La democracia y las elecciones están firmemente incrustadas en las prácticas sociales, conocimientos, y objetos.

Este texto aborda los huertos familiares en espacios urbano-rurales como aporte a una “economía del don” en la realidad de la pandemia, caracterizada por el crecimiento del desempleo, el empobrecimiento y la inseguridad alimentaria. La investigación se constituyó como un estudio de caso que analiza una experiencia de huerto familiar en Itoupava Central, un barrio con cerca de 28 mil habitantes, en la ciudad de Blumenau, SC, Brasil. La investigación encontró que un huerto familiar, que permite compartir la producción de alimentos orgánicos y plántulas de árboles frutales a través de donaciones y acompañado de reflexión y motivación solidaria, constituye un símbolo importante de una "economía del don", y tiene el potencial resignificar las acciones colectivas y la producción de alternativas frente a la realidad del individualismo, la pobreza y la necesidad de relaciones socioambientales que hagan referencia a la importancia de la sustentabilidad económica, social y ambiental y el cuidado del medio ambiente en el post- período de pandemia.
COVID-19’S INFLUENCE ON AFRICA’S UNIVERSITY GOVERNANCE DOMAIN: DEBRIEFING SOUTH AFRICA–NIGERIA SETTINGS
Authors: Paul Okudolo Ikemefuna Taire , Amenaghawon Francis
Published: September 2022

Studies acknowledge that COVID-19 is a game-changer resulting in an operational “new normal” across organizational endeavours including university governance. One effect of COVID-19 on social change organizations like universities in Africa is that it intensified operational disruptions. The study utilizes narrative analysis to evaluate the impact of COVID-19 on university governance using South Africa-Nigeria settings as a template to generalize for Africa. Its data stems from a methodological qualitative orientation, implying that the narrations derive from unstructured interviews with key players within the university system. It is anchored on a conceptual framework founded on the ontology of African administrative and organizational culture that dialectically prompts epistemological analysis. The ontology facet deals with the status quo of university governance before COVID-19, denoting universities as mini societies reflecting the continent’s general operational culture. The epistemology aspect dealt with knowledge generation, indicating innovation African universities need to adopt to operate effectually during and aftermath of COVID-19. It finds that e-university governance application in Nigeria is underdeveloped compared to South Africa’s model which is basic. However, it concludes that improved investment in digitalizing operations of universities is imperative for their successful governance in a postCOVID-19 pandemic epoch in Africa.

Recently, there is a growing number of publications about the complicated course of the COVID-19 in children. The literature describes only a few cases of acute cerebrovascular diseases. In the case described in this paper, an 11‑year-old boy presented with COVID-19 complicated by an ischemic stroke. Moderate ischemic stroke (pedNIHSS 14 points) occurred on the 7th day after infection with the SARS-CoV-2 and the background of the multisystem inflammatory syndrome. It has started with the left hemiplegia, hemianesthesia, central-type facial moderate palsy, and pseudobulbar palsy. Focal brain ischemia in the right hemisphere brain and occlusion of the right middle cerebral artery was confirmed by neuroimaging data. The treatment observed regression of neurological symptoms: there were minimal movements in his left arm and leg, facial muscles, also improved gulping and speech. After 1.5 months, the stroke was provided clinical examination: no markers predisposing to hypercoagulability or a prothrombotic state, as well as markers of systemic diseases. According to neuroimaging data, was occurred recanalization of occluded middle cerebral artery, was postischemic changes. This case shows the possibility of stroke against the background of COVID-19 in children without somatic problems and makes the doctor more vigilant during the treatment of COVID-19.

The article authors basing on the analysis of recent publications and the scientific research results of pedagogical and military-pedagogical issues, establish that there are almost no fundamental methodological studies in military-pedagogical science. It is noted that integration processes are observed in the application of methodological tools. The author's team draws readers' attention to the fact that modern military-pedagogical science uses methods of scientific search, which are actively used by such sciences as logic, sociology, psychology, economics and some others. The article describes and provides examples of the application of a number of methods that are used by the above mentioned sciences. Such methods are: the method of expert assessments, which allows to obtain and summarize the opinions of experts on the subject of scientific research; systematisation and classification, which allows to organize many phenomena, processes, and facts; forecasting, which is based on actions to obtain, process and generate information about the future; monitoring, which is a continuous and long-term observing of the course of military-pedagogical events and processes; sociometric method, which is used for intra-group processes diagnostics; content analysis, it is a method of qualitative and quantitative analysis of the content of a document that allows to perform an off-text reality deep analysis; methods of mathematical and statistical processing of the obtained empirical data. In conclusion, the authors note the need for a thorough methodological study of the features of applying the military-pedagogical scientific methods, the results of which would be used as representatives of militarypedagogical theory and practice.
TRANSGENERATIONAL NEMESIC CHAOS IN THE ANTIGONE: SOPHOCLES' CLASSICAL FOREWARNING TO HEGEMONISTS

If the multiple dualities in the Antigone are considered in an intragenerational context, i.e. as concordant conflicts in Antigone's lifetime, then the plot of the drama might be perceived as stochastic and rather unpredictable as to its catastrophic outcome, i.e. the destruction of all protagonists, while their polis is entrapped in a seemingly unstable equilibrium. But if the dualities are viewed in a transgenerational context, i.e. as the final episode in a chain of dramatic and intertwined events that span many a generation of conflict between the royal house of the Labdacids and the divine or cosmic order, then the plot might be considered as deterministic and rather predictable as to its tragic outcome. From such perspective, the downfall of the dynasty might have been predestined by divine providence or cosmic teleology: In a transgenerational period, the polis might have been converging to a stable equilibrium all along, in line with the natural order of the universe, i.e. an equilibrium preconditioned on the extinction of the hubristically aberrant dynasty. In this context, the underlying forewarning of Sophocles to hegemonists comes to the fore in the Antigone: Even the most powerful and self-righteous perpetrators of hubris may in fact act as unaware pawns of divine will or cosmic teleology – pawns entrapped in a predestined and dynamically chaotic course of action that ultimately, in a transgenerational period, leads to the absolute prevalence of invincible Nemesis.
POETRY AND FICTION BY MYKOLA VINGRANOVSKYJ IN ENGLISH TRANSLATIONS

The article examines the poetry and fiction by Mykola Vingranovskyj in English translations. Attention is paid to the chronological sequence of translations, the figures of translators and the works selected for translation, their equivalence to the original. The first translation of M. Vingranovskyj's fiction (the short story "White Flowers") appeared with the assistance of Yu. Lutsky in Canada and aimed at popularizing Ukrainian literature among students. The short story opens the extremely lyrical world of Mykola Vingranovskyj, where the story revolves not around the event, but around the feelings, which brings the short story closer to poetry. The novella was included to the anthology (Modern Ukrainian Short Stories, 1973) as the example of the prose of the sixties (shistdesyatnyky), which departed from socialist-realist ideological canons and turned to the emotional and expressive potential of artistic language. The translation of Yuri and Moira Lutsky is marked by the desire to convey as fully as possible the author's individual style, including figurative metaphor, to create a text equivalent to the original in communicative orientation. The collection Summer Evening (1987), translated by Anatoliy Bilenko, was published after M. Vingranovskyj was awarded the Taras Shevchenko National Prize of Ukraine (1984). The collection includes stories for children's audiences, conveying children's perception of the world: Chest, Shaggi, The Gosling, Good Night, What Makes the World Spin, Summer Evening. A. Bilenko's translations are notable for the adequacy of the reproduction of artistic and stylistic features of the original, semantic equivalence. Some translated poems, which emphasize the civic component (Sistine Madonna, To My Sea, On the Golden Table, The First Lullaby, Star Prelude) were included to the anthology of Ukrainian poetry (Anthology of Soviet Ukrainian Poetry, 1982), and Russian translators were involved in translating the poems (Dorian Rottenberg, Michael McGreg), which significantly reduced the artistic value of poetry. During the times of independent Ukraine, competitions for translations to the writer's anniversaries were initiated. However, translated works have not been published in collections and anthologies. Active work on translations of M. Vingranovskyj's works is still ahead.

Features of Frustration Behavior in Left-Handed Children of Primary School Age
Authors: Donskova E.S.
Published: September 2022

Сhanges in the social situation of development of primary school students are accompanied by frustrating situations. However, there is a lack of comparative studies of frustration behavior of left-handed children is emphasized. Purpose of the work: to compare the features of the frustration behavior of left-handed and right-handed junior schoolchildren. Research hypotheses: H1: between left-handed and right-handed younger students there are differences in the nature of reactions to a frustrating situation; H2: left-handed younger students show higher levels of anxiety and fear. 124 elementary school students were compared: with the leading left hand (n=62) and the leading right hand (n=62). 70 are boys and 54 are girls. The following methods were used: “S. Rosenzweig test. The technique of pictorial frustration. Children’s version”; “Self-assessment test. Characteristics of emotionality”; “Children’s version of the scale of apparent anxiety”; “Questionnaire for identifying fears”. Hypotheses were tested for statistically significant differences using the parametric Student’s t-test and the nonparametric Mann-Whitney U-test. The effect size is calculated using Cohen’s d value. The influence of independent factors (gender and leading hand) on the studied indicators was checked using two-way ANOVA. It was shown that in a situation of frustration in left-handed children, more often than in right-handed children, there is a tendency to fixation on an obstacle (p≤0.01), and extrapunitive reactions (p≤0.05). The results of the study are focused on practical application in the field of education and can be used in the development of programs of psychological and pedagogical support for left-handed children.
A New Large Scale SVM for Classification of Imbalanced Evolving Streams

Published: September 2022

Classification from imbalanced evolving streams possesses a combined challenge of class imbalance and concept drift (CI-CD). However, the state of imbalance is dynamic, a kind of virtual concept drift. The imbalanced distributions and concept drift hinder the online learner’s performance as a combined or individual problem. A weighted hybrid online oversampling approach,”weighted online oversampling large scale support vector machine (WOOLASVM),” is proposed in this work to address this combined problem. The WOOLASVM is an SVM active learning approach with new boundary weighing strategies such as (i) dynamically oversampling the current boundary and (ii) dynamic weighing of the cost parameter of the SVM objective function. Thus at any time step, WOOLASVM maintains balanced class distributions so that the CI-CD problem does not hinder the online learner performance. Over extensive experiments on synthetic and real-world streams with the static and dynamic state of imbalance, the WOOLASVM exhibits better online classification performances than other state-of-the-art methods.
