    Learning Complex Policy Distribution with CEM Guided Adversarial Hypernetwork

    No full text
    Cross-Entropy Method (CEM) is a gradient-free direct policy search method, which has greater stability and is insensitive to hyperparameter tuning. CEM bears similarity to population-based evolutionary methods, but, rather than using a population it uses a distribution over candidate solutions (policies in our case). Usually, a natural exponential family distribution such as multivariate Gaussian is used to parameterize the policy distribution. Using a multivariate Gaussian limits the quality of CEM policies as the search becomes confined to a less representative subspace. We address this drawback by using an adversarially-trained hypernetwork, enabling a richer and complex representation of the policy distribution. To achieve better training stability and faster convergence, we use a multivariate Gaussian CEM policy to guide our adversarial training process. Experiments demonstrate that our approach outperforms state-of-the-art CEM-based methods by 15.8% in terms of rewards while achieving faster convergence. Results also show that our approach is less sensitive to hyper-parameters than other deep-RL methods such as REINFORCE, DDPG and DQN.Interactive Intelligenc

    Bu çalıĢmada, Bayatî‟nin Câm-ı Cem-âyîn adlı eserindeki Cem Sultan‟a ait hasb-i hâl türü Ģiirler üzerinde durulmuĢtur. ÇalıĢmanın amacı eserden yola çıkarak Ģairin hayatı, kiĢiliği, Ģiirleri ve dönemi hakkında bilinmeyenleri ortaya koymaktır. ÇalıĢma, ġehzâde Cem (ö. 900/1495) ve Hasan Bayatî (ö. 900/1495‟te sağ) arasında Kâbe‟de Ģiirle baĢlayan dostluğu; Câm-ı Cem-âyîn adlı eserin yazılıĢ sebebi, konusu, önemi ve neĢrini içermektedir. Bu çalıĢmayla, Cem‟in Türkçe divanında yer almayan iki Ģiiri incelenmiĢ olup hem bu Ģiirlerden hem de Ali Emîrî‟nin tespitlerinden yola çıkılarak Cem Sultan‟a dair yeni bilgilere ulaĢılmıĢtır. Türk-Osmanlı neslinin öz tarihçesi olan Câm-ı Cem-âyîn, Bayatî ve özellikle Cem Sultan‟ın hayat ve kiĢiliğine dair önemli bilgiler içermesi bakımından oldukça önemli bir eserdir. ÇalıĢma giriĢ, iki bölüm, sonuç ve kaynakçadan oluĢmaktadır. GiriĢ bölümünde, Câmı Cem-âyîn‟i eski harflerle neĢreden Ali Emîrî‟nin ön sözü ve eserin dîbâcesindeki bilgiden hareketle eser ve müellifi hakkında bilgi verilmiĢ, sonra adı geçen eserin Ģekil, içerik ve yayın bilgisi üzerinde durulmuĢtur. Birinci bölümde, iki farklı eserden Cem‟in hayatına dair yeni bilgiler aktarılmıĢ, Bayatî‟nin Farsça bir gazeli ve bu gazele Cem Sultan tarafından yazılan Türkçe bir nazire gazel incelenmiĢtir. Ġkinci bölümde, Câm-ı Cemâyîn‟in hatime bölümünde yer alan ve çalıĢmamıza konu olan tarihî bir “tahmisnâme” Ģekil, içerik, dil ve anlatım özellikleri yönünden incelenmiĢtir. Hasb-i hâl türündeki bu önemli manzumenin tam metni, dil içi çevirisi ve notlarla birlikte verildikten sonra sonuç ve kaynakça yazımıyla çalıĢma tamamlanmıĢtır.This study focuses on Cem Sultan‟s poems written in the tone of friendly chat included in the book Câm-ı Cem-âyîn by Bayatî. The study aims to reveal what is unknown about the poet‟s life, personality, poems and his era. This study is concerned with friendship between Prince Cem (date of death 900/1495) and Hasan Bayatî (date of death 900/1495 in life) which started in Kaaba, the reason why the book “Câm-ı Cem-âyîn” was written, its importance and publication. This current study analyses two poems of Cem Sultan which are not included in his Turkish Collection of Poems, and makes explorations about Cem Sultan by setting out from these two poems and from the findings obtained by Ali Emîrî. Câm-ı Cem-âyîn, a short history of Ottoman Turks lineage, is a very important work in that it includes information on Bayatî‟s and especially Cem Sultan‟s life and personality. The study consists of introduction, two chapters, conclusion and a chapter about bibliography. In the introduction part the preface written by Ali Emîrî, information about the work based on the preface, and about the author is presented and then information on the form, content and publication of the book is offered. In Chapter One information about Cem Sultan‟s life is given based on two different studies, and a lyric poem (gazal) written by Bayatî in Persian language and a poem written by Cem Sultan in parallel to Bayatî‟s gazal in Turkish language (nazire gazal) are also analysed in this chapter. In Chapter Two a historical “tahmisnâme”, which is included in the epilogue of Câm-ı Cem-âyîn and which is the subject matter of this study is analysed in terms of form, content, and linguistic and stylistic properties. Having paraphrased the full text of this important poem- which is in the tone of friendly chat- with explanatory notes, the book reaches the conclusion and ends with bibliography giving references

    Does strict employment protection discourage job creation? Evidence from Croatia

    No full text
    Employment protection legislation in Croatia is among the most strict in Europe. Firing is difficult and costly, and flexible forms of employment are limited. Is this apparent rigidity reflected-as one would expect based on standard economic theory-in low labor market dynamics? Is job creation low and hiring limited? Is the job security of insiders achieved at the cost of outsiders not being able to enter thelabor market? The author attempts to answer these questions by examining job flows. If the employment protection legislation is binding, then job and worker turnover should be low. He shows that this is indeed the case. Hiring is limited and the average job tenure is very long in Croatia. Job destruction is low, however job creation is still lower. The result is accumulation of unemployment, in large part due to new labor market entrants not being able to find a job. The high degree of job protection also seems to strengthen the bargaining position of insiders and results in relatively high wages. So, wages in Croatia are higher than among its competitors, even after adjusting for productivity. These high labor costs are likely to contribute to limited job creation in existing firms, but also are likely to discourage the entry of-and thus job creation in-new firms. The author presents evidence that firm growth has been indeed limited in Croatia, contributing to the low employment level. The author examines other potential causes of high unemployment in Croatia (the unemployment benefit system, labor taxation, the wage structure, and skill and spatial mismatches). He argues that they do not play a substantial part in accounting for poor labor market outcomes in Croatia. The author concludes that the stringent employment protection legislation is the key labor market institution behind low job creation and high unemployment. Based on this he recommends specific measures aimed at liberalizing the labor market to foster job creation and employment.Labor Management and Relations,Labor Policies,Labor Markets,Environmental Economics&Policies,Trade Finance and Investment,Labor Markets,Labor Management and Relations,Labor Standards,Banks&Banking Reform,Environmental Economics&Policies

    Top 50 Most-Cited Publications on Blepharoplasty Surgery Between 2015 and 2022: From a Current Altmetric Perspective of Research Impact

    No full text
    Background Blepharoplasty is one of the most-performed esthetic operations, and social media platforms have become an influential tool for distributing scientific information. Because the internet has gained popularity among medical experts and surgeons to connect with the public, we aimed to evaluate the altmetric–bibliometric analysis of the top 50 most-cited articles on blepharoplasty surgery between 2015 and 2022 and assess correlations with various metrics. Methods “Blepharoplasty” was searched using the WoS database, and the altmetric score was obtained. Co-authors, keywords, country of authors, and cited journal network map analysis were created using VOSviewer for the 485 publications retrieved. The articles' focus was examined quantitatively and the most prolific parameters were identified. Results The most research was performed by the USA, the most productive institution was the “University of California System,” and the most prolific author was “Wonn CH.” The number of citations ranged from 37 to 9, and altmetric attention scores ranged from 54 to 0. The most articles and citations peaked in 2021. Altmetric and Twitter scores were moderately correlated with journal metrics but there were no correlations with citation counts. Conclusion The first comprehensive altmetric analysis on blepharoplasty surgery offers new guidelines for upcoming articles by demonstrating the recent investigation trends, prolific parameters, and zones with potential for the public's attention and education, providing valuable data regarding the distribution of scientific knowledge in social media platforms and to the general public. A social network may be used to increase the visibility of scientific articles apart from creating brands and markets

    Education and earnings inequality in Mexico

    No full text
    Education attainment levels increased dramatically for Mexico's labor force in the 1980s and early 1990s. In parallel, the country experienced a pronounced increase in earnings inequality from 1984-94, reflected in a higher dispersion of wages and an absolute decline in the real incomes of less educated, poorer Mexicans. This increased wage dispersion presents policymakers with a tradeoff between efficiency considerations (favoring increased spending on higher education) and equity considerations (favoring a more equal distribution of per student spending) in the allocation of fiscal resources to education. The author concludes that the best way to deal with this equity-efficiency tradeoff is to encourage greater private participation in higher education. His main findings are that: a) The accumulation of human capital during 1984-94, as proxied by education attainment, was accompanied by a more equal distribution of education attainment levels over that period and, thus, exerted an equalizing effect on the distribution of incomes. The increased income inequalityobserved over that period appears to be caused by an increased rate of skill-based technological change, whose transmission to Mexico and other developing countries may have been facilitated by the increased openness of their economies. b) The greater dispersion of wager observed in Mexico during the past decade raised the rates of return on investing in higher education, reversing the traditional pattern where primary education exhibits the highest rates of return. c) The social rates of return across levels of schooling were more uniform in 1994 than in 1984, suggesting a more efficient assignment of education spending. At the same time, the distribution of spending on education became more egalitarian, as per student spending in higher education declined markedly compared with per student spending at the primary level. This surprising coincidence in the pattern of spending on education was only possible because Mexico started out with a very distorted resource allocation in education that was both highly inequitable and inefficient. As Mexico's policymakers are on the way to correcting these distortions, the opportunities for avoiding the equity-efficiency tradeoff within Mexico's centralized education framework will become progressively exhausted. d) There is little reason to expect the pace of technological change, which appears mainly responsible for raising wage dispersion and the relative returns on higher education, to abate. Efficiency considerations dictate that Mexico should respond by devoting more resources to higher education. However, the federal budget, which traditionally has financed the lion's share of higher education costs in Mexico, is unable to accommodate additional spending on higher education, while spending cuts elsewhere in the education sector are bound to raise serious equity questions. Thus, to avoid falling behind in terms of human capital accumulation, greater private sector participation is necessary, at least, in terms of cost recovery from the main beneficiaries of higher education.Decentralization,Teaching and Learning,Environmental Economics&Policies,Public Health Promotion,Curriculum&Instruction,Teaching and Learning,Environmental Economics&Policies,Health Monitoring&Evaluation,Gender and Education,Curriculum&Instruction
