Despite significant progress, deep reinforcement learning (RL) suffers from data-inefficiency and limited generalization. Recent efforts apply meta-learning to learn a meta-learner from a set of RL tasks such that a novel but related task could be solved quickly. Though specific in some ways, different tasks in meta-RL are generally similar at a high level. However, most meta-RL methods do not explicitly and adequately model the specific and shared information among different tasks, which limits their ability to learn training tasks and to generalize to novel tasks. In this paper, we propose to capture the shared information on the one hand and meta-learn how to quickly abstract the specific information about a task on the other hand. Methodologically, we train an SGD meta-learner to quickly optimize a task encoder for each task, which generates a task embedding based on past experience. Meanwhile, we learn a policy which is shared across all tasks and conditioned on task embeddings. Empirical results on four simulated tasks demonstrate that our method has better learning capacity on both training and novel tasks and attains up to 3 to 4 times higher returns compared to baselines.

Covalent Interactions

The S66 benchmark for non-covalent interactions has been re-evaluated using explicitly correlated methods with basis sets near the one-particle basis set limit. It is found that post-MP2 ‘high-level corrections’ are treated adequately well using a combination of CCSD(F12*) with (aug-)cc-pVTZ-F12 basis sets on the one hand, and (T) extrapolated from conventional CCSD(T)/heavy-aug-cc-pV{D,T}Z on the other hand. Implications for earlier benchmarks on the larger S66×8 problem set in particular, and for accurate calculations on non-covalent interactions in general, are discussed. At a slight cost in accuracy, (T) can be considerably accelerated by using sano-V{D,T}Z+ basis sets, whereas half-counterpoise CCSD(F12*)(T)/cc-pVDZ-F12 offers the best compromise between accuracy and computational cost.

Much of Alvin Plantinga’s Where the Conflict Really Lies(2011) will contain few surprises for those who have been following his work over the past decades. This —I hasten to add — is nothing against the book. The fact alone that his ideas on various topics, which have appeared scattered throughout the literature, are now actualized, applied to the debate about the (alleged) conflict between science and religion, and organized into an overarching argument with a single focus makes this book worthwhile. Moreover, I see this book making significant progress on two opposite ends of the spectrum of views about science and religion. On the one end, we find the so-called new atheists and other conflict-mongers. Compared to the overheated rhetoric that oozes from their writings, this book is a breath of fresh air. Plantinga cuts right to the chase and soberly exposes the bare bones of the new atheists’ arguments. It immediately becomes clear how embarrassingly bare these bones really are. On the other end of the spectrum are theologians and scientists who envisage harmony and concord between science and religion.

В современных стрессовых и негативных внешних экологических условиях растет число неуверенных в себе, эмоционально неустойчивых тревожных детей. В работах А.И.Захаровой, Н.В.Имеладзе, Л.М. Прихожановой говорится, что когда человек постоянно волнуется - возникает паника. Согласно анализу исследований многих авторов, детская тревога, с одной стороны, имеет психодинкамическую природу, с другой-является результатом социализации. По мнению психологов, у учащихся наблюдается высокий уровень тревожности в процессе обучения. В результате изучения данной проблемы установлено, что уровень тревожности и успеваемость ребенка тесно взаимосвязаны. Процесс приобщения детей, пришедших в школу, к процессу обучения тесно связан с процессом паники . In the current stressful and negative external environmental conditions, the number of insecure, emotionally unstable children with anxiety is growing. In the works of A.I. Zakharova, N.V. Imeladze, L.M. Prikhozhan, it is said that when a person is constantly agitated, panic occurs. According to the analysis of the research of many authors, child anxiety, on the one hand, has a psychodynamic nature, and on the other-is the result of socialization. According to psychologists, there is a high level of anxiety in students ' learning process. As a result of the study of this problem, it was found that the level of anxiety and the child's academic performance are closely related. The process of adaptation of children to the learning process is closely related to the panic process. However, the level of anxiety in lower-class students affects the learning process and learning outcomes.

This study aims to examine the laws of dowry money decoration that are common in the community. The innovation and soul of art that is channeled through décor of dowry money is proven to produce beautiful and unique works, so as to attract the attention and interest of the wider community. However, because to produce beautiful and unique works, a high level of creativity is needed, so not everyone can do it. On the one hand, this phenomenon opens up quite good business opportunities, but on the other hand, it should be watched out, because in some conditions it contains the practice of buying and selling currencies with nominal differences. Through this study, I would like to uncover the law of buying and selling practices decorating dowry money and decorating services. As I also intend to present an applicative solution for the community so that they can still channel their artistic talents without violating Shari’ah law.

<p>Iris Hanika’s commercially and critically successful novel Treffen sich zwei makes use of several techniques in the characterisation of its protagonists. Many of its reviews focus on the author’s deliberate placement of links to a wider literary context. Their interest extends from questions of genre-mixing through to the identification of direct quotes from other authors’ works. The critical preoccupation with intertexts demonstrates their importance for the readers’ response to the novel. More specifically, certain reviews highlight the important role intertexts play in the characterisation of the protagonists. This study catalogues the intertexts, metaphors and parodies in Treffen sich zwei and, by means of quantitative analysis, identifies high-level patterns in the use of these techniques. In particular, patterns are identified between, on the one hand, the different narrative functions of the intertexts and, on the other hand, the different ways in which they are interwoven in the text. The data also shows that distinct patterns are associated with each of the two protagonists and that certain patterns change in the course of the novel in parallel with the changes in the relationship between them. This quantitative evidence is supported by a more detailed, qualitative approach, which examines how specific intertexts or metaphors are used for the purposes of characterisation. In addition, variations in voice are used to distinguish the two main protagonists in a manner consistent with the intertexts and metaphors. It is thanks to the combination of these techniques that the theme of meeting encapsulated in the title, Treffen sich zwei, is woven into the textual fabric of the novel.</p>

The National Education World is currently trying to improve the ability of its students to think critically and creatively. One of these efforts has been pursued through evaluations that also lead to critical reflection. This research is a descriptive analysis of the final semester evaluation questions that are examined from the point of view of high-level thinking [HOTS]. The reference to the HOTS criteria is that the researcher refers to the opinions of King and his friends. From the manuscript data, the issues examined are samples from the Bandung area. The results of the analysis show that 10 out of 15 HOTS ranges proposed by King are already included in the scripts made by the teachers. On the one hand, it shows the teacher's creativity in compiling questions. On the other hand, all these questions do not refer to the HOTS criteria as planned. Therefore, there is a need to increase teachers' skills in compiling scripts as HOTS. This increase can be done through teacher training.Keywords: Evaluation, HOTS, critical thinking and creativity thingking

The Relationship

The aim of this paper was to check whether there exists a relationship between volunteering involvement and the level of communion, agency and degree of support for ethical codes. The questions concerned whether persons involved in volunteering (compared to those not involved) are characterized, on the one hand, by a higher intensity of agency and communion, on the other, a higher level of declared support for ethical codes (ethics of autonomy, universal good, dignity and collectivism). In order to find the answer, a study was carried out in which participated 37 people involved in hospice volunteering (including 19 women) and 34 non-volunteers (including 18 women).The results of the study show the existence of an assumed relationship in the case of agency and communion. As for ethical codes, the results did not provide evidence of the relationship between the level of their support and volunteering. The results of the presented study lead to the conclusion that selfless action for the benefit of the other people is associated with a high level of agency and communion, and not only with a high ethical level. Hence the postulate for pedagogical practice to shape and develop a sense of agency and communion in children and youth.

This paper provides general conditions on the direct demand functions in a Bertrand duopoly with differentiated substitute products and constant marginal costs, that allow an unambiguous ranking of firms' equilibrium payoffs between sequential play (with both order of moves) on the one hand, and simultaneous play on the other. The main results are that (i) when prices are strategic complements, both firms prefer sequential moves (with either order) to simultaneous moves, (ii) when prices are strategic substitutes, both firms prefer simultaneous moves to moving second in sequential play, and (iii) in the mixed strategic substitute/complement case, one firm is as in (i) and the other as in (ii). Thus, sequential moves would plausibly endogenously emerge in cases (i) and (iii), with one specified leader in the latter case. The analysis relies crucially on the theory of supermodular games, and is conducted at a high level of generality, dispensing with concavity-type assumptions, and taking into account both the issues of existence and possible non-uniqueness of the different equilibria involved.

The article is devoted to the representation of the concept death in poem “Autumn” («Höst») written by Stig Dagerman in 1954. Author wrote it 10 days before suicide. Thus, poem may be considered as occurring before death. This writing is one of a number works where Stig Dagerman addresses himself to a topic death. Concept death is one of the key concepts for humanity: philosophers, painters and writers have been studying it for centuries. Death concept realization can be found in language with the help of various linguistic means: direct and indirect naming units (on the form of metonymic and metaphorical transfers), conventional epithets, colours and images which can be either culture-universal or authorial. In poem of interest concept death is present mostly by metaphorical transfers and colour epithets and one realization through the use of metonymic transfer. The poem includes traditional, universal cultural as well as authorial images. On the one part these speak about importance of studying the concept in global culture, on the other part these speak about Stig Dagerman’s high level of excellence as a poet.
