    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

    Effects of slice thickness of quince (Cydonia oblonga Miller) , microwave incident power and air drying temperature on antioxidant activity and total phenolic content of quince were investigated during drying in microwave and air drying. Optimum conditions were found to be: i) for microwave drying, 285 W and 4.14 mm thick (maximum antioxidant activity) and 285 W and 6.85 mm thick (maximum total phenolic content), and ii) for air drying, 75 ºC and 1.2 mm thick (both maximum antioxidant activity and total phenolic content). Drying conditions were optimized by using the response surface methodology. 13 experiments were carried out considering incident microwave powers from 285 to 795 W, air temperature from 46 to 74 ºC and slice thickness from 1.2 to 6.8 mm

    The main objective of this study was to determine the effect of different frying oils and frying methods on the formation of trans fatty acids and the oxidative stability of oils. Sunflower, canola and commercial frying oils, the most commonly used oils for frying potatoes in the fast food industry, were used as the frying medium. The value for total polar compounds was highest when commercial frying oil was used in the microwave oven (22.5 +/- 1.1). The peroxide value, as an indicator of oil oxidation, was lowest for microwave oven frying (2.53 +/- 0.03). The K-232 and K-270 values were 0.41 +/- 0.04 and 0.18 +/- 0.02, respectively, for commercial frying oil in the microwave oven. The lowest free fatty acid content was recorded for the commercial frying oil used in the deep-fat fryer at 190 A degrees C. The highest iodine value was measured for sunflower oil used in the deep-fat fryer (148.14 +/- 0.07), indicating a greater degree of unsaturation. The lowest trans fatty acid value was recorded for sunflower oil in the microwave oven (0.17 +/- 0.05), with a higher overall amount of total trans fatty acids observed for oils after frying in the electrical deep-fat fryer compared to the microwave. Sunflower oil was favourable for both frying methods in terms of the trans fatty acid content

    The main objective to this study was to determine of the drying time of asparagus slices in hot air oven and microwave oven and to optimize drying time and effective moisture diffusivity was done in terms of process parameters. The drying time of asparagus slices varied from 140 to1485 min for hot air oven and from 75 to 2580 sec for microwave drying. Effective moisture diffusivity of asparagus was between from 0.20x10(-10) m(2)/s to 2.90 x 10(-10) m(2)/s for hot air oven and 8.89x10(-10) m(2)/s to 75.26x10(-10) m(2)/s for microwave oven. The results presented indicated that process parameters were significantly important on drying time and effective moisture diffusivity for hot air oven drying. The less drying time was obtained in microwave oven compare to hot air oven. Drying time was affected by the concentration of CaCl2 and thickness of slice and effective moisture diffusivity was significantly influenced by the microwave power and slice thickness during microwave drying

    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.

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
