Short-term trend prediction in financial time series data Ozorhan, Mustafa Onur; Toroslu, İsmail Hakkı; Şehitoğlu, Onur Tolga (Springer Science and Business Media LLC, 2019-10-01) This paper presents a method to predict short-term trends in financial time series data found in the foreign exchange market. Trends in the Forex market appear with similar chart patterns. We approach the chart patterns in...
A parallel aerostructural shape optimization platform for airplane wings Oktay, Erdal; Arpacı, Anıl; Şehitoğlu, Onur Tolga; Akay, Hasan Umur (null; 2019-05-17) A parallel design platform is developed for aerostructural shape optimization of airplane wings. The developed tools consist of a panel method-based aerodynamic solver, a finite element-based structural solver, geometry an...
A strength-biased prediction model for forecasting exchange rates using support vector machines and genetic algorithms Ozorhan, Mustafa Onur; Toroslu, İsmail Hakkı; Şehitoğlu, Onur Tolga (2017-11-01) This paper addresses problem of predicting direction and magnitude of movement of currency pairs in the foreign exchange market. The study uses Support Vector Machine with a novel approach for input data and trading strate...
Three-dimensional structural topology optimization of aerial vehicles under aerodynamic loads Oktay, Erdal; AKAY, HASAN UMUR; Şehitoğlu, Onur Tolga (2014-03-20) A previously developed density distribution-based structural topology optimization algorithm coupled with a Computational Fluid Dynamics (CFD) solver for aerodynamic force predictions is extended to solve large-scale probl...
A pattern classification approach for boosting with genetic algorithms Yalabık, Ismet; Yarman Vural, Fatoş Tunay; Üçoluk, Göktürk; Şehitoğlu, Onur Tolga (2007-11-09) Ensemble learning is a multiple-classifier machine learning approach which produces collections and ensembles statistical classifiers to build up more accurate classifier than the individual classifiers. Bagging, boosting ...
Gene Level Concurrency in Genetic Algorithms Şehitoğlu, Onur Tolga; Üçoluk, Göktürk (Springer-Verlag, 2007-01-01) This study describes an alternative concurrency approach in genetic algorithms. Inspiring from implicit parallelism in a physical chromosome, a vertical concurrency is introduced. Proposed gene process model allows genetic...
Gene level concurrency in genetic algorithms Şehitoğlu, Onur Tolga; Üçoluk, Göktürk (2003-01-01) This study describes an alternative concurrency approach in genetic algorithms. Inspiring from implicit parallelism in a physical chromosome, a vertical concurrency is introduced. Proposed gene process model allows genetic...
A building block favoring reordering method for gene positions in genetic algorithms Şehitoğlu, Onur Tolga; Üçoluk, Göktürk (null; 2001-07-11) This work proposes an algorithm to speedup convergence of genetic algorithms that is based on the investigation of neighbouring gene values of the successful individuals of the chromosome pool. By performing some statistic...
Lexical rules and Lexical Organization: Productivity in the Lexicon Şehitoğlu, Onur Tolga; Bozşahin, Hüseyin Cem (Springer, 1999-01-01) Most of the books about computational (lexical) semantic lexicons deal with the depth (or content) aspect of lexicons, ignoring the breadth (or coverage) aspect. This book presents a first attempt in the community to addre...
Resolution of Dropped Pronouns in a Phrase Structure Grammar Şehitoğlu, Onur Tolga (1997-08-11) In this work intra-sentential resolution of Turkish dropped pronouns in a phrase structure grammar is studied. Turkish is a pro-drop and free constituent order language. The resolution scheme for dropped pronouns depends o...
