  • 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 ...
  • Sequential Monte Carlo localization using bluetooth low-energy beacons 
    Daniş, Fahri Serhan. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    We model the tracking of a Bluetooth Low-Energy (BLE) moving transceiver as a hidden Markov model, and filter the latent positions using sequential Monte Carlo. A novel aspect of our approach is the development of an ...
  • Quality of experience - driven dynamic adaptive streaming over HTTP 
    Özçelik, İhsan Mert. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    Dynamic Adaptive Streaming över HTTP (DASH) became the pillax of mul timedia content delivery mechanisms in the last decade. Given fluctuating network conditions, over-the-top content platforms struggle with delivering a ...
  • Stress detection and management in daily life using wearable sensors 
    Can, Yekta Said. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    Stress has become an integral part of our modern society. Researchers investi gated ways to cope with it to alleviate its negative effects on human health, society and economy. At this point, widespread usage of smartphones, ...
  • 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 ...
  • Developing a comprehensive framework for sentiment analysis in Turkish 
    Aydın, Cem Rıfkı. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    In this thesis, we developed a comprehensive framework for sentiment analysis that takes its many aspects into account mainly for Turkish. We have also proposed several approaches specific to sentiment analysis in English ...
  • Optimization of next generation solar-powered radio access networks 
    Pamuklu, Turgay. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2020., 2020.)
    Due to the incontrovertible effects of global warming, society grows its sustainabil ity awareness regularly, and governments start to change their energy policies to pro mote green energy sources. However, mobile network ...
  • A concurrent programming system with a flexible structure
