Centroid based Tree-Structured Data Clustering Using Vertex/Edge Overlap and Graph Edit Distance DİNLER, DERYA; Tural, Mustafa Kemal; Özdemirel, Nur Evin (Springer Science and Business Media LLC, 2020-06-01) We consider a clustering problem in which the data objects are rooted m-ary trees with known node correspondence. We assume that the nodes of the trees are unweighted, but the edges can be unweighted or weighted. We measur...
Extracting the Boundaries of Clusters: A Post-Clustering Tool for Spatial Datasets İNKAYA, TÜLİN; Kayaligil, Sinan; Özdemirel, Nur Evin (World Scientific Pub Co Pte Lt, 2020-04-01) Boundary extraction is a fundamental post-clustering problem. It facilitates interpretability and usability of clustering results. Also, it provides visualization and dataset reduction. However, it has not attracted much a...
Tree-structured Data Clustering Dinler, Derya; Tural, Mustafa Kemal; Özdemirel, Nur Evin (2019-11-04) Tree-structured Data ClusteringWe consider a clustering problem in which data objects are rooted trees withunweighted or weighted edges and propose a k-means based algorithm whichrepeats assignment and update steps until c...

Tree-structured Data Clustering Dinler, Derya; Tural, Mustafa Kemal; Özdemirel, Nur Evin (2018-07-08) Traditional clustering techniques deal with point data. However, improving measurement capabilities and the need for deeper analyses result in collecting more complex datasets. In this study, we consider a clustering probl...
A matheuristic for binary classification of data sets using hyperboxes Akbulut, Derya; İyigün, Cem; Özdemirel, Nur Evin (null; 2018-07-08) In this study, an optimization approach is proposed for the binary classification problem. A Mixed Integer Programming (MIP) model formulation is used to construct hyperboxes as classifiers, minimizing the number of miscla...
