Joint MK Classification of Stellar Spectra with Distance-Aware CNNs Sezen, Volga; Temizel, Alptekin (2025-10-19)
Progressive Disease Image Generation with Ordinal-Aware Diffusion Models Kurt, Meryem Mine; Çağlar, Ümit Mert; Temizel, Alptekin (2025-10-01) Background/Objectives: Ulcerative Colitis (UC) lacks longitudinal visual data, which limits both disease progression modeling and the effectiveness of computer-aided diagnosis systems. These systems are further constrained...
Towards fair decentralized benchmarking of healthcare AI algorithms with the Federated Tumor Segmentation (FeTS) challenge Zenk, Maximilian; et. al. (2025-07-01) Computational competitions are the standard for benchmarking medical image analysis algorithms, but they typically use small curated test datasets acquired at a few centers, leaving a gap to the reality of diverse multicen...
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...
