İnci, Alperen; Temizel, Alptekin; Department of Modeling and Simulation (2022-9-2)
Many people suffer from Ulcerative Colitis (UC), which is a chronic inflammatory bowel disease. UC exhibits itself as ulcers, inflammation, and sores in the colon. In order to provide proper treatment, an expert physician ...
DETECTION OF ANOMALOUS FUND TRANSFERS BETWEEN DIFFERENT BANKS
Tunçay, Abdullah Mert; Akagündüz, Erdem; Department of Modeling and Simulation (2022-9-02)
There are various risks associated with fund transfers between banks, including frauds and abuse of the banking system. Any anomaly in a fund transfer network must be detected and learned, since unexpected messages or tran...
RANKPCSF: A DISEASE MODULE IDENTIFICATION METHOD BY INTEGRATING NETWORK PROPAGATION WITH PRIZE-COLLECTING STEINER FOREST
Eskin, Arda; Otlu Sarıtaş, Burçak; Tunçbağ, Nurcan; Department of Bioinformatics (2022-9-2)
Identification of disease modules may lead to a better understanding on the progression of diseases, finding more accurate biomarkers, and drug targets. In this study, we develop a hybrid method – RANKPCSF- combining the s...
DESIGN, DEVELOPMENT AND USABILITY OF A LOCATION-BASED GAME
Badali Naghadeh, Faraz; Çağıltay, Kürşat; Department of Modeling and Simulation (2022-9-02)
Location-based games (LBG) have been created with the aim of blending reality with the virtual world. At its core, LBGs utilize user location as the main element since they can be played almost anywhere. The LBGs have been...
A NEW FRAMEWORK TO DESIGN AND GENERATE VIRTUAL LABORATORIES FOR CIVIL ENGINEERING

One of the most common methods of communication is written communication. Written communication has been found in various forms over the years and has changed shape with technical and technological developments. Today, wri...
A comparison of deep neural network architectures for COVID-19 detection using CT chest images
Sarıoğlu, Mehmet Tunahan; Mumcuoğlu, Ünal Erkan; Department of Medical Informatics (2022-9)
Coronavirus Disease 2019 (COVID-19) has rapidly spread around the world since December 2019. Due to the low confidence in the real-time reverse transcription-polymerase chain reaction (RT-PCR) test, which is considered the...
INTEGRATION OF MACHINE LEARNING AND ENTROPY METHODS FOR POST-GENOME-WIDE ASSOCIATION STUDIES ANALYSIS
Yaldız, Burcu; Aydın Son, Yeşim; Department of Medical Informatics (2022-8-31)
Non-linear relationships between genotypes play an essential role in understanding the genetic interactions of complex disease traits. Genome-Wide Association Studies (GWAS) have revealed a statistical association between ...
Interaction of Spatial Configurations and Language: An Experimental Inquiry
Yılmaz, Naz Buse; Çakır, Murat Perit; Acartürk, Cengiz; Department of Cognitive Sciences (2022-8-31)
The perception and description of space are one of the most fundamental phenomena in human cognition and evolution. Knowing where we are and telling allies about it is vital information from an evolutionary perspective. Th...
Semantic dimensionality reduction during language acquisition: A window into concept representation
Özcan, Rojda; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2022-8-31)
We explore the dimensionality in the semantic representations derived from the Eve fragment of the CHILDES database to gain insights into whether or not semantic dimensionality reduc- tion (DR) occurs during language acqui...
ARTIFICIAL LEARNING-BASED ANALYSIS OF MOLECULAR, CLINICAL TRIALS AND PATENT DATA FOR IMPROVED DRUG DEVELOPMENT
Çıray, Fulya; Aydın Son, Yeşim; Doğan, Tunca; Department of Medical Informatics (2022-8-31)
Drug development is a costly process, especially in terms of the required time and money. Many promising drug candidates are eliminated at late development stages, e.g., phase II or III of clinical trials, due to insuffici...
Nominalization and Argument Structure: An Experiment with the NOMLEX Database
Kızıldemir, Melis; Bozşahin, Hüseyin Cem; Department of Cognitive Sciences (2022-8-31)
This study presents a method for predicting syntactic structures of deverbal event nominals that are derived from verbs used in their transitive meaning. The study takes a data-driven approach and fine-tunes pre-trained de...
