Bu proje gerçek hayat finans sektöründen esinlenilmiştir. Yaklaşımımız istatistiksel araç olan ROC eğrisinin optimizasyonu üzerinedir. İstatistiğin modelden bağımsız değil, modele dayalı matematik yaklaşımını kullanarak problemimiz için çözüm önerilebilir. Yeni yaklaşımımız kredilendirme ve kalite analiz ve kontrolü konularında klasik istatistik yöntemlerinden daha başarılı ve gerçekçidir. Ekteki bağlantıdaki döküman buna örnek teşkil eder. (http://144.122.137.55/gweber/ ve http://www.iam.metu.edu.tr/mscthesis/fatmayerlika yathesis.pdf). 2) Tanım: a) Konu ile ilgili literatür taraması; konunun güncel durumu ve bulunduğu aşama: ROC eğrisinin optimizasyonun yanı sıra, modelimizde en iyiyi elde etmek için dengelenmis sınıf sayılarına bakmaktayız. Gerçekte bu model, lineer olmaya modeller sınıfına girmektedir. Gauss-Newton ve Levenberg-Marquardt yöntemleri ile regüle edilmiş lineer regresyon teknikleri modeldeki her basamağı tanımlamakta kullanılmaktadır. Bu projeyle finans sektörüne

An analysis of change in pre-service teacher education in Turkey by using vhaos theory
Somuncuoğlu, Yeşim; Yıldırım, Ali; Şimşek, Hasan; Department of Educational Sciences (2003)
This study was conducted to investigate the change in pre-service teacher education in Turkey by using Chaos Theory. The research questions were the following: 1) How did the 1982 restructuring relate to the 1998 restructuring? (2) What were the reasons for the anomalies that led to the 1998 restructuring? (3) How did the 1998 process of transformation work? (4) At which stage of the curve is the system now? (5) What are the possible paths the new model may evolve? The data sources in this qualitative resea...
Parameter Estimation For Actuarial Sciences And Financial Mathematics İn Stochastic Differential Equations By Additive And Nonlinear Models And Continuous Optimization
Weber, Gerhard Wilhelm(2009-12-31)
Bu proje gerçek hayat finans sektöründe stokastik diferansiyel eşitliklerin finansal matematik uygulamaları gözönüne alınarak sunulmuştur. Finans sektör verileri kullanılarak sokastik yaklaşım modelleri kurmak çok zor bir uygulamadır. Bu modeller fiyat süreçleri, faiz oranları ve değişkenlikleri ve çeşitli türevleri içerebilir. Projedeki amacımız matematik biliminin modern yöntemlerini kullanarak, özellikle süreklilik ve ters problem teorileriyle optimal modelleme yapmaktır. Bu şekilde istatistiğin modeld...
AN ASSESSMENT OF LOCALIZATION POLICIES IN TURKEY: THE CASE OF MOBILE TELECOMMUNICATION SECTOR
Acar, Musa; Erdil, Erkan; Department of Science and Technology Policy Studies (2022-9)
The primary purpose of this thesis is to evaluate Turkey's innovation policies in the mobile telecommunications sector. A limited number of global companies produce mobile telecommunication technologies. These companies dominate the infrastructure market. Policymakers in Turkey have set domestic production in the electronic communications sector as a target in many strategy documents. ULAK company was established, and HTK, which hosts approximately 150 companies, has formed for production in the indus...
A Study on the Spatial Organization of Post-Revolutionary Houses in Tabriz (1980s)
Golabi, Maryam; Bilsel, Fatma Cânâ (2020-01-01)
The present study aims to explore how socio-cultural values of post-revolutionary period influenced the spatial organization of dwellings in Iran. The Islamic revolution of Iran (1979) extremely changed many aspects of Iranians'private and public life due to its religious nature. The notions of 'social spacerphysical space' and 'habitus'-practice of everyday life- proposed by Pierre Bourdieu are used as conceptual tools in this research based on a case study. The attempt is to understand how the structure o...
A simulation study of scheduling algorithms for packet switching networks
Babur, Özgür; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2003)
A scheduling algorithm has the primary role in implementing the quality of service guaranteed to each flow by managing buffer space and selecting which packet to send next with a fair share of network. In this thesis, some scheduling algorithms for packet switching networks are studied. For evaluating their delay, jitter and throughput performances, a discrete event simulator has been developed. It has been seen that fair scheduling provides, fair allocation of bandwidth, lower delay for sources using less ...
