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 ...
Tuning model complexity using cross-validation for supervised learning

Yıldız, Olcay Taner. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2005., 2005.)

In this thesis, we review the use of cross-validation for model selection and propose the MultiTest method which solves the problem of choosing the best of multiple candidate supervised models. The MultiTest algorithm ...
