Accelerating backpropagation using effective parameters at each step and an experimental evaluation
(Taylor & Francis LTD, 2008)An acceleration of backpropagation algorithm with momentum (BPM) is introduced. At every stage of the learning process, local quadratic approximation of the error function is performed and the Hessian matrix of the quadratic ... -
Algorithms for the spatial median
(Springer International Publishing, 2015)The spatial median can be defined as the unique minimum of a strictly convex objective function. Hence, its computation through an iterative algorithm ought to be straightforward. The simplest algorithm is the steepest ... -
Alpha-skew generalized t distribution [Distribución t generalizada alfa sesgada]
(Universidad Nacional de Colombia, 2015)The alpha-skew normal (ASN) distribution has been proposed recently in the literature by using standard normal distribution and a skewing approach. Although ASN distribution is able to model both skew and bimodal data, it ... -
Analysis of international debt problem using artificial neural networks and statistical methods
(Springer, 2010)It is known from the scientific researches that artificial neural networks are alternatives of statistical methods such as regression analysis and classification in recent years. Since multi-layer backpropagation neural ... -
Analysis of organizational commitment and work-family conflict in view of doctors and nurses
(Routledge Journals, Taylor & Francis LTD, 2012)The present study investigates the relationship between organizational commitment and work-family conflict for medical doctors and nurses. Using canonical analysis on questionnaire, this relation has been tested distinctively ... -
Analysis of some flexible families of distributions for estimation of wind speed distributions
(Elsevier Sci LTD, 2012)The wind speed distribution is the basis for the assessment of wind energy potential needed for the design of wind farms. Therefore, the proper specification of the wind speed distribution is of special importance. In this ... -
Analysis of the modified weibull distribution for estimation of wind speed distribution
(Association for Computing Machinery, 2015)Finding suitable wind speed distribution is one of the most important tasks for the correct estimation of wind energy potential of the specified region. The Weibull distribution is the well-known and suggested distribution ... -
Analysis of the upper-truncated Weibull distribution for wind speed
(Pergamon-Elsevier Science LTD, 2015)Accurately modeling wind speed is critical in estimating the wind energy potential of a certain region. In order to model wind speed data smoothly, several statistical distributions have been studied. Truncated distributions ... -
Analysis of wind speed distributions: Wind distribution function derived from minimum cross entropy principles as better alternative to Weibull function
(Pergamon-Elsevier Science LTD, 2008)In this study, the minimum cross entropy (MinxEnt) principle is applied for the first time to the wind energy field. This principle allows the inclusion of previous information of a wind speed distribution and covers the ... -
Analyzing family planning by logistic regression
(2013)The importance of family planning is rising for countries whose population are too young or old and where infant mortality is high. There are several factors on family planning which is having the desired number of children ... -
ANN forecasting models for ISE national-100 index
(Wayne State University, 2010)Prediction of the outputs of real world systems with accuracy and high speed is crucial in financial analysis due to its effects on worldwide economics. Because the inputs of the financial systems are timevarying functions, ... -
An Application of Fuzzy Coding in Multiple Correspondence Analysis for Transforming Data from Continuous to Categorical
(Old City Publishing Inc, 2012)In some research, it can be necessary to know the categorical data groups to which the data measured by interval and ratio scale belong. The fuzzy sets principle can be used to transform the original continuous data into ... -
An application of fuzzy time series to improve ISE forecasting
(2010)The problem of fuzzy time series forecasting plays an important role in many scientific areas such as statistics and neural networks. While forecasting fuzzy time series, most of forecasting applications use the same length ... -
An application of various nonparametric techniques by nonparametric regression splines
(2012)In this paper we made a comparison study between regression spline, penalized spline, and their Bayesian versions: adaptive Bayesian regression spline and Bayesian penalized spline with a different number of observations. ... -
Assessing the Quality of the Natural Cubic Spline Approximation
(World Scientific Publ Co Pte LTD, 2009)In large samples, central limit and saddle-point approximation theory suggest that spline functions having just two or three knots may be used to approximate the log- likelihood function for a single parameter, with the ... -
Assessment of Fuel Consumption Using Factorial Experiments, Regression Trees and MARS
(World Scientific And Engineering Acad And Soc, 2009)The purpose of this paper is to determine the effects that are significant on the fuel consumption of F-4 aircrafts by using three different statistical methods and compare the results of those different methods. The ... -
Asymmetric control limits for small samples
(Springer, 2009)When designing control charts, it is usually assumed that the measurement in the subgroups are normally distributed. The assumption of normality implies that the control limits for a chart for sample averages will be ... -
Biplots of fuzzy coded data
(Elsevier Science BV, 2011)A biplot, which is the multivariate generalization of the two-variable scatterplot, can be used to visualize the results of many multivariate techniques, especially those that are based on the singular value decomposition. ... -
Bulanık mantıkta korelasyon katsayısı; meterolojik olaylarda bir uygulama
(2007)Korelasyon iki yada daha çok sayıda değişken arasındaki ilişkiyi göstermekte ilişki miktarı ise korelasyon katsayısı ile belirlenmektedir. İki değişken arasındaki doğrusal ilişkinin derecesini belirleyen korelasyon katsayısını ... -
Bütünleşik Veri: Kayıtlı Motorlu Kara Taşıtlarına Farklı Bir Bakış
(2018)Bir bütüne ait parçalardan oluşan veriler değişik bilim alanlarında karşımıza çıkmaktadır. Yapısı gereği çok değişkenli olan bu veriler ilgi çekici özelliklere sahiptir. Bu tür veriler sabit bir toplamla sınırlandırılmasından ...
