This assignment problem is called word sense disambiguation(WSD). Many papers in the ... -
Animal sound classification using a convolutional neural network
Şaşmaz, Emre; Tek, Faik Boray (IEEE, 2018-12-06)In this paper, we investigate the problem of animal sound classification using deep learning and propose a system based on convolutional neural network architecture. As the input to the network, sound files were preprocessed ... -
Automated cell nucleus detection for large-volume electron microscopy of neural tissue
Tek, Faik Boray; Kroeger, Thorben; Hamprecht, Fred A.; Mikula, Shawn (IEEE, 2014-04-29)Volumetric electron microscopy techniques, such as serial block-face electron microscopy (SBEM), generate massive amounts of image data that are used for reconstructing neural circuits. Typically, this requires time-intensive ... -

Biclustering expression data based on expanding localized substructures
Erten, Cesim; Sözdinler, Melih (Springer-Verlag Berlin Heidelberg, 2009)Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. We provide ... -
Budding trees
Yıldız, Olcay Taner; İrsoy, Ozan; Alpaydın, Ahmet İbrahim Ethem (IEEE Computer Soc, 2014-08-24)We propose a new decision tree model, named the budding tree, where a node can be both a leaf and an internal decision node. Each bud node starts as a leaf node, can then grow children, but then later on, if necessary, its ... -
Bulanık mantık kullanılarak sese duyarlı aydınlatma
Kanburoğlu, Ali Buğra; Şaşmaz, Emre (IEEE, 2017-10-31)Sanayileşmenin ve teknolojinin gelişmesiyle birlikte, geçmişte çözülememiş olan problemler daha kolay çözülebilir hale gelmiştir. İnsan beyninin çalışma mekanizması çeşitli metotlar halinde bilgisayarlarda uygulanmaya ... -
Calculating the VC-dimension of decision trees
Yıldız, Olcay Taner; Aslan, Özlem; Alpaydın, Ahmet İbrahim Ethem (IEEE, 2009)We propose an exhaustive search algorithm that calculates the VC-dimension of univariate decision trees with binary features. The VC-dimension of the univariate decision tree with binary features depends on (i) the ... -
Chunking in Turkish with conditional random fields
Yıldız, Olcay Taner; Solak, Ercan; Ehsani, Razieh; Görgün, Onur (Springer-Verlag, 2015-04-14)In this paper, we report our work on chunking in Turkish. We used the data that we generated by manually translating a subset of the Penn Treebank. We exploited the already available tags in the trees to automatically ... -
Colored simultaneous geometric embeddings
Brandes, Ulrik; Erten, Cesim; Fowler, J. Joseph; Frati, Fabrizio; Geyer, Markus; Gutwenger, Carsten; Hong, Seok-Hee; Kaufmann, Michael; Kobourov, Stephen G.; Liotta, Giuseppe; Mutzel, Petra; Symvonis, Antonios (Springer-Verlag Berlin, 2007)We introduce the concept of colored simultaneous geometric embeddings as a generalization of simultaneous graph embeddings with and without mapping. We show that there exists a universal pointset of size n for paths colored ... -
Comparison of Turkish proposition banks by frame matching
Ak, Koray; Bakay, Özge; Yıldız, Olcay Taner (IEEE, 2018-12-06)By indicating semantic relations between a predicate and its associated participants in a sentence and identifying the role-bearing constituents, SRL provides an extensive dataset to understand natural languages and to ... -
