Adaptive kernel density estimation with generalized least square cross-validation
Demir, Serdar (Hacettepe Univ, Fac Sci, 2019)Adaptive kernel density estimator is an efficient estimator when the density to be estimated has long tail or multi-mode. They use varying bandwidths at each observation point by adapting a fixed bandwidth for data. It is ... -
Criteria for Best Architecture Selection in Artificial Neural Networks
Bal, Çağatay; Demir, Serdar (World Scientific Publishing Co., 2022)Architecture selection in artificial neural networks is a critical process which determines a satisfactory neural network model(s) that will lead to the most accurate results. The architecture that minimizes the difference ... -
EFFECTS OF MAGNESIUM AND CALCIUM CATIONS ON BIOFILM FORMATION BY Sphingomonas paucimobilis FROM AN INDUSTRIAL ENVIRONMENT
Güvensen, Nur Ceyhan; Demir, Serdar; Özdemir, Güven (Parlar Scientific Publications (P S P), 2012)Bacterial biofilms may form on all surface-associated natural and many industrial environments. Biofilm formation requires particular notice due to its associated risks for human health and its impact on environmental ... -
Forecasting COVID19 Reliability of the Countries by Using Non-Homogeneous Poisson Process Models
Güler Dinçer, Nevin; Demir, Serdar; Yalçın, Muhammet Oğuzhan (Springer, 2022)Reliability is the probability that a system or a product fulfills its intended function without failure over a period of time and it is generally used to determine the reliability, release and testing stop time of the ... -
Forecasting TRY/USD Exchange Rate with Various Artificial Neural Network Models
Bal, Çağatay; Demir, Serdar (Assoc Information Communication Technology Education & Science, 2017)Exchange rate forecasting is one of the most common subjects among the forecasting problem field. Researchers and academicians from many different disciplines proposed various approaches for better exchange rate forecasting. ... -
Fuzzy panel data analysis
Yalçın, Muhammet Oğuzhan; Güler Dinçer, Nevin; Demir, Serdar (University of Kuwait, 2021)In statistical and econometric researches, three types of data are mostly used as cross-section, time series and panel data. Cross-section data are obtained by collecting the observations related to the same variables of ... -
ON THE ADAPTIVE NADARAYA-WATSON KERNEL REGRESSION ESTIMATORS
Demir, Serdar; Toktamış, Oniz (Hacettepe Univ, Fac Sci, 2010)Nonparametric kernel estimators are widely used in many research areas of statistics. An important nonparametric kernel estimator of a regression function is the Nadaraya-Watson kernel regression estimator which is often ...
