We present an approach for regression problems that employs analytic continued fractions as a novel representation. Comparative computational results using memetic algorithm are reported in this work. Our experiments included fifteen other different machine learning approaches including five genetic programming methods symbolic and ten methods. The comparison on training test generalization was...

Direct measurement of soil hydraulic characteristics is costly and time-consuming. Also, the method is partly unreliable due to soil heterogeneity and laboratory errors. Instead, soil hydraulic characteristics can be predicted using readily available data such as soil texture and bulk density using pedotransfer functions (PTFs). Artificial neural networks (ANNs) and statistical regression are t...
Logic regression is a generalized regression and classification method that is able to make Boolean combinations as new predictive variables from the original binary variables. Logic regression was introduced for case control or cohort study with independent observations. Although in various studies, correlated observations occur due to different reasons, logic regression have not been studi...
In this paper we focus on the application of global stochastic optimization methods to extremum estimators. We propose a general stochastic method—the master method —which includes several stochastic optimization algorithms as a particular case. The proposed method is sufficiently general to include the Solis–Wets method, the improving hit-and-run algorithm, and a stochastic version of the zigz...
محاسبات کوانتومی یک روش جدید و کارآمد در سرعت دادن به محاسبات با استفاده از پدیده های مهمی از قبیل برهم نهی1 ، تداخل2 ، عدم موجبیت3 ، ناجایگزیدگی4 و تکثیرناپذیری5 ارائه می کند. و الگوریتم های کوانتومی ابزار کار برای این نوع محاسبات می باشند که با پیدایش محاسبات کوانتومی به عنوان زیر شاخه آن مورد توجه قرار گرفته اند که در تبدیل زمان محاسبات از نوع نمائی به چند جمله ای دارای اهمیت فراوان در محاسب...
this paper uses a psopc model based non-destructive damage identification procedure using frequency and modal data. the objective function formulation for the minimization problem is based on the frequency changes. the method is demonstrated by using a cantilever beam, four-bay plane truss and two-bay two-story plane frame with different scenarios. in this study, the modal data are provided nume...
