Context-Sensitive Model Learning for Lung Nodule Detection
Ogul, B. Buket; Ogul, Hasan; Sumer, Emre (2016)Nodule detection in chest radiographs is a main component of current Computer Aided Diagnosis (CAD) systems. The problem is usually approached as a supervised classification task of candidate nodule segments. To this end, ... -
Data Integration for Gene Expression Prediction
Bayrak, Tuncay; Ogul, Hasan (2018)In computational system biology, one challenging topic is predicting the exact value of gene expression for further meta-analysis. For this, a data integration approach and regression based task are proposed. To improve ... -
A deep learning approach for sepsis monitoring via severity score estimation
Asuroglu, Tunc; Ogul, Hasan (2021)Background and objective: Sepsis occurs in response to an infection in the body and can progress to a fatal stage. Detection and monitoring of sepsis require multi-step analysis, which is time-consuming, costly and requires ... -
DeepMBS: Prediction of Protein Metal Binding-Site Using Deep Learning Networks
Haberal, Ismail; Ogul, Hasan (2017)The tertiary structure of a protein indicates what vital function that protein fulfills in the cell. Prediction of the metal binding comformation of a protein from its sequence is a crucial step in predicting its tertiary ... -
Eliminating Rib Shadows in Chest Radiographic Images Providing Diagnostic Assistance
Ogul, Hasan; Ogul, B. Buket; Agildere, A. Muhtesem; Bayrak, Tuncay; Sumer, Emre (2016)A major difficulty with chest radiographic analysis is the invisibility of abnormalities caused by the superimposition of normal anatomical structures, such as ribs, over the main tissue to be examined. Suppressing the ... -
Evaluating Text Features for Lyrics-Based Songwriter Prediction
Kirmaci, Basar; Ogul, Hasan (2015)We offer an automated way of estimating the author of a song using only its lyrics content. To this end, we introduce a complete text classification framework which takes raw lyrics data as input and report estimated ... -
