  • A tree based categorical variable encoding strategy in supervised learning tasks 
    Gazioğlu, Mine. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    Categorical variables are present in most real-world datasets, often consisting of a high number of levels, referred to as high-cardinality categorical variables. Most machine learning algorithms do not have an innate ...
  • Example-dependent cost-sensitive gradient boosting machines for credit scoring 
    Kurtuluş, İlker. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    Although most of machine learning algorithms try to minimize cost-insensitive losses, many real world applications require cost-sensitive approaches where misclassifi cation costs among classes differ from each other. In ...
  • Fair recommendation through conditioning on systematic presentation in recommender systems 
    Bozal, Özge. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    Recommendation engines are interactive systems aiming to predict users’ top preferences according to their choices. A limitation of the recommender systems is that over time the recommendations get narrower in scope. That ...
  • Probabilistic discriminative region descriptor for time series classification 
    İşiaçık, Pınar Süngü. (Thesis (M.S.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2022., 2022)
    Detecting discriminivative regions is a recent promising concept in many differ ent domains for various dataset types such as image, text and time series. In time series domain, time series might be large and high dimensional ...
