  • A bayesian approach to textile defect detection problem and a comparative analysis 
    Yakın, Abdullah. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    The purpose of this thesis was to detect the defects on textile fabric images using the particle filters. We approached the problem from a Bayesian perspective and represented the model in a state space formulation. To ...
  • A bayesian approach to the clustering problem with application to gene expression analysis 
    Fidaner, Işık Barış. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2016., 2016.)
    This thesis investigates methods for extraction of information from gene expression time series data. These time series provide indirect measurements about the underlying biological mechanisms, hence their analysis heavily ...
  • Bayesian analysis of a project's net present value under risk 
    Görgen, Ömer. (Thesis (M.A.) - Bogazici University. Institute of Social Sciences, 1982., 1982.)
  • Bayesian EEG source reconstruction using Markov chain Monte Carlo methods 
    Yıldız, Gökçen. (Thesis (M.S.)-Bogazici University. Institute of Biomedical Engineering, 2007., 2007.)
  • Bayesian methods for real-time pitch tracking 
    Şimşekli, Umut. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2010., 2010.)
    In this thesis, we deal with probabilistic methods to track the pitch of a musical instrument in real-time. Here, we take the pitch as a physical attribute of a musical sound which is closely related to the frequency ...
  • Bayesian network based pathway analysis of high throughput biological data 
    Korucuoğlu, Melike. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2013., 2013.)
    Biological data production has been increasing at an unprecedented pace with the advancements of microarrays and next-generation sequencing technologies. Such High Throughput Biological Data (HTBD), requires detailed ...
  • Biclustering using nonparametric Bayesian methods 
    Çelik, Safiye. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    Multiway clustering is a popular analysis method due to its several potential applications. Various techniques have been developed to cluster di erent entities of a data matrix simultaneously by taking relational entries ...
  • Blind Bayesian multiuser detection for impulse radio UWB systems 
    Ay, Ahmet Gökhan. (Thesis (M.S.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    In this thesis, we address the blind parameter estimation and multiuser de- tection problems for impulse radio ultra-wide band (UWB) systems under frequency selective fading. The frequency selective UWB channel, having a ...
  • Estimating the schedule delay of marine projects in Turkey deu to pssible delay causes by using bayesian belief network model 
    Elibol, Ozan. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2018., 2018.)
    Marine projects have become one of the most fascinating industries in Turkey because of their enormous contribution to the local economic growth. Thereof, the completion of these projects on time has critical importance ...
  • Identifying gene interactions for time series microarray data using dynamic Bayesian Networks and external biological knowledge 
    Ağyüz, Umut. (Thesis (M.S.) - Bogazici University. Institute of Biomedical Engineering, 2013., 2013.)
    DNA hybridization arrays measure the expression levels for thousands of genes. These measurements provide us with a “snapshot” of transcription levels in the cell. A major challenge in computational biology is to identify ...
  • Maintenance of a multi-component dynamic system under partial observations 
    Ünlüakın, Demet Özgür. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    This thesis studies the maintenance of a dynamic system consisting of several components which age in time at a given failure rate. The states of the components are hidden. In each decision epoch, the decision of whether ...
  • Revealing gene interactions using Bayesian Networks 
    İşçi, Şenol. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2012., 2013.)
    High throughput biological data (HTBD) targeting understanding of biochemical interactions in the cell can best be analyzed, and explained within the context of networks and pathways. Such data generally represents stochastic ...
  • Sequential Bayesian modeling of non-stationary non-Gaussian processes 
    Gençağa, Orhan Deniz. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    This thesis brings a unifying approach for modeling non-stationary non-Gaussian signals which are widely encountered in many multidisciplinary research fields. In the literature, different approaches have been used to model ...
  • Sequential Monte Carlo approoach to inference in Bayesian choice models 
    Gündoğdu, İlker. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Monte Carlo methods, such as Markov Chain Monte Carlo (MCMC) and Sequential Monte Carlo (SMC), have extensive use cases in probabilistic modeling and inference. They usually appear as a way of drawing samples from a ...
  • Statistical analysis of cognitive signals measured by fNIRS 
    Çifçi, Rifat Koray. (Thesis (Ph.D.)-Bogazici University. Institute of Biomedical Engineering, 2008., 2008.)
    Further standardization in signal processing tools is needed in the area of functional near infrared spectroscopy (fNIRS) before it is recognized as a reliable neuroimaging modality. This thesis study attempts to present ...
