  • 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 ...
  • Algorithms for learning from online human behavior and human interaction with learning algorithms 
    Çapan, Gökhan. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    In modern digital systems, algorithms that deliver personalized content shape the user experience and affect user satisfaction, hence long-term engagement with the system. What the system presents also influences the parties ...
  • Bayesian approaches for privacy preserving data sharing 
    Ermiş, Beyza. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    In this thesis, we focus on the data fusion problem where we have heterogeneous data which is collected from di↵erent sources and stored in the form of matrices and higher-order tensors and propose coupled matrix and tensor ...
  • Bayesian methods for network traffic analysis 
    Kurt, Barış. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Statistical information about tra c patterns help a service provider to characterize its network resource usage and user behavior, infer future tra c demands, detect tra c and usage anomalies, and possibly provide insights ...
  • Distance approximations between high and multi-dimensional structures 
    Semerci, Murat. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    In this thesis, we focus on distance approximation methods between high and multi-dimensional structures and their applications. Two novel methods using distance approximations are proposed and they are applied to anomaly ...
  • Fast high-dimensional temporal point processes with applications 
    Türkmen, Ali Caner. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    Large sets of continuous-time discrete event streams are often in the focus of seismology, neuroscience, finance, behavioral science among other scientific and engi neering disciplines. In this work, we explore a set of ...
  • Generalized tensor factorization 
    Yılmaz, Yusuf Kenan. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2012., 2012.)
    This thesis proposes a unified probabilistic framework for modelling multiway data. Our approach establishes a novel link between probabilistic graphical models and tensor factorization, that allows us to design arbitrary ...
  • Tensor fusion: learning in heterogeneous and distributed data 
    Şimşekli, Umut. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2015., 2015.)
    In this thesis, we focus on coupled matrix and tensor factorization models; that provide a good modeling accuracy { practicality trade o for modeling large-scale and/or heterogeneous data that are collected from diverse ...
