Bağlam ağaçları ile ardışık doğrusal olmayan bağlanım
(IEEE, 2014-04)Bu bildiride, ardışık doğrusal olmayan bağlanım problemi incelenmiş ve bağlam ağaçları kullanarak etkili bir öğrenme algoritması sunulmuştur. Bu amaçla, bağlanım alanı parçalara ayrılmış ve oluşan bölgeler bağlam ağacı ile ... -
Çağrı merkezi metin madenciliği yaklaşımı
(IEEE, 2017-05)Günümüzde çağrı merkezlerindeki görüşme kayıtlarının sesten metne dönüştürülebilmesi görüşme kaydı metinleri üzerinde metin madenciliği yöntemlerinin uygulanmasını mümkün kılmaktadır. Bu çalışma kapsamında görüşme ... -
Data-driven two-stage inventory problem
(Bilkent University, 2021-09)In this thesis, we consider two-stage newsvendor problem where the decision maker selling a seasonal product only uses the historical demand information in her decisions. In our setting, there are two decisions to be made: ... -
Dedollarization in Turkey after decades of dollarization: a myth or reality?
(Elsevier BV, 2007)The paper analyzes dollarization in the Turkish economy given the evidence on dedollarization signals. On conducting a Vector Autoregression (VAR) model, the empirical evidence suggests that dollarization has mostly been ... -
Differences in the accumulation and distribution profile of heavy metals and metalloid between male and female crayfish (Astacus leptodactylus)
(2013)Concentrations of selected heavy metals and a metalloid were measured by ICP-MS in crayfish (Astacus leptodactylus) collected from Lake Hirfanli, Turkey. Aluminum (Al), chromium (52Cr, 53Cr), copper ( 63Cu, 65Cu), manganese ... -
Estimation of a change point in a hazard function based on censored data
(Springer New York LLC, 2003)The hazard function plays an important role in reliability or survival studies since it describes the instantaneous risk of failure of items at a time point, given that they have not failed before. In some real life ... -
Experimental and finite element analysis of EDM process and investigation of material removal rate by response surface methodology
(2013)In this study, thermal modeling and finite element simulation of electrical discharge machining (EDM) has been done, taking into account several important aspects such as temperature-dependent material properties, shape ... -
Income inequality and economic convergence in Turkey: a spatial effect analysis
(Sage Publications, 2009)Even though the convergence of regional per capita income has been a highly debated issue internationally, empirical evidence regarding Turkey is limited as well as contradictory. This article is an attempt to investigate ... -
Inflation and inflation uncertainty in the G-7 countries
(Elsevier BV, 2005)This study examines the relationship between inflation and inflation uncertainty in the G-7 countries for the period from 1957 to 2001. The causality between the inflation and inflation uncertainty is tested by using the ... -
Mathematical and numerical modeling of the effect of input-parameters on the flushing efficiency of plasma channel in EDM process
(Elsevier Ltd, 2013)In the present study, the temperature distribution on the surface of workpiece and tool during a single discharge in the electrical discharge machining process has been simulated using ABAQUS code finite element software. ... -
Online distributed nonlinear regression via neural networks
(IEEE, 2017)In this paper, we study the nonlinear regression problem in a network of nodes and introduce long short term memory (LSTM) based algorithms. In order to learn the parameters of the LSTM architecture in an online manner, ... -
Persistency of Turkish export shocks: a quantile autoregression (QAR) approach
(Springer, 2016)This study analyzes the persistency of total and disaggregated Turkish exports for different shock magnitudes using the quantile autoregression (QAR) method in line with Koenker and Xiao (J Am Stat Assoc 99:775–787, 2004). ... -
Piecewise nonlinear regression via decision adaptive trees
(IEEE, 2014-09)We investigate the problem of adaptive nonlinear regression and introduce tree based piecewise linear regression algorithms that are highly efficient and provide significantly improved performance with guaranteed upper ... -
Pulse shape design using iterative projections
(IEEE, 2005-09)In this paper, the pulse shape design for various communication systems including PAM, FSK, and PSK is considered. The pulse is designed by imposing constraints on the time and frequency domains constraints on the ... -
Support vector networks for prediction of floor pressures in shallow cavity flows
(IEEE, 2007)During the last decade, Support Vector Machines (SVM) have proved to be very successful tools for classification and regression problems. The representational performance of this type of networks is studied on a cavity ... -
Transformational leadership and organizational innovation: the roles of internal and external support for innovation
(Wiley-Blackwell Publishing, 2009)Leadership has been suggested to be an important factor affecting innovation. A number of studies have shown that transformational leadership positively influences organizational innovation. However, there is a lack of ...
