Class distance weighted cross entropy loss for classification of disease severity Polat, Gorkem; Çağlar, Ümit Mert; Temizel, Alptekin (2025-04-01) Assessing disease severity with ordinal classes, where each class reflects increasing severity levels, benefits from loss functions designed for this ordinal structure. Traditional categorical loss functions, like Cross-En...
TopoMaskV2: Enhanced Instance-Mask-Based Formulation for the Road Topology Problem Kalfaoğlu, Muhammet Esat; Öztürk, Halil İbrahim; Kılınç, Özsel; Temizel, Alptekin (2024-09-30)
Egocentric activity recognition using two-stage decision fusion Arabacı, Mehmet Ali; Sürer, Elif; Temizel, Alptekin (2024-01-01) The widespread adoption of wearable devices equipped with advanced sensor technologies has fueled the rapid growth of egocentric video capture, known as First Person Vision (FPV). Unlike traditional third-person videos, FP...

IR Reasoner: Real-time Infrared Object Detection by Visual Reasoning Gündoǧan, Meryem Mine; Aksoy, Tolga; Temizel, Alptekin; Halıcı, Uğur (2023-01-01) Thermal Infrared (IR) imagery is utilized in several applications due to their unique properties. However, there are a number of challenges, such as small target objects, image noise, lack of textural information, and back...
Improving the Computer-Aided Estimation of Ulcerative Colitis Severity According to Mayo Endoscopic Score by Using Regression-Based Deep Learning Polat, Gorkem; Kani, Haluk Tarik; Ergenc, Ilkay; Alahdab, Yesim Ozen; Temizel, Alptekin; Atug, Ozlen (2022-11-01) Background Assessment of endoscopic activity in ulcerative colitis (UC) is important for treatment decisions and monitoring disease progress. However, substantial inter- and intraobserver variability in grading impairs the...
Class Distance Weighted Cross-Entropy Loss for Ulcerative Colitis Severity Estimation POLAT, GÖRKEM; ERGENÇ, İLKAY; KANİ, HALUK TARIK; ÖZEN ALAHDAB, YEŞİM; ATUĞ, ÖZLEN; Temizel, Alptekin (2022-07-25) In scoring systems used to measure the endoscopic activity of ulcerative colitis, such as Mayo endoscopic score or Ulcerative Colitis Endoscopic Index Severity, levels increase with severity of the disease activity. Such r...
