Using chains of bottleneck transitions to decompose and solve reinforcement learning tasks with hidden states Aydın, Hüseyin; Çilden, Erkin; Polat, Faruk (2022-08-01) © 2022 Elsevier B.V.Reinforcement learning is known to underperform in large and ambiguous problem domains under partial observability. In such cases, a proper decomposition of the task can improve and accelerate the learn...
Does depth estimation help object detection? Cetinkaya, Bedrettin; Kalkan, Sinan; Akbaş, Emre (2022-06-01) Ground-truth depth, when combined with color data, helps improve object detection accuracy over baseline models that only use color. However, estimated depth does not always yield improvements. Many factors affect the perf...

To reduce the adverse effects of radio link failures’ on the user experience, mobile operators require intelligent monitoring syst...
Next-Generation Payment System for Device-to-Device Content and Processing Sharing Kihtir, Fatih; Yazıcı, Mehmet Akif; Oztoprak, Kasim; Alpaslan, Ferda Nur (2022-04-01) Recent developments in telecommunication world have allowed customers to share the storage and processing capabilities of their devices by providing services through fast and reliable connections. This evolution, however, ...
Hand-crafted versus learned representations for audio event detection Kucukbay, Selver Ezgi; Yazıcı, Adnan; Kalkan, Sinan (2022-04-01) Audio Event Detection (AED) pertains to identifying the types of events in audio signals. AED is essential for applications requiring decisions based on audio signals, which can be critical, for example, for health, survei...
Partitioning and Reordering for Spike-Based Distributed-Memory Parallel Gauss--Seidel Torun, Tugba; Torun, F. Sukru; Manguoğlu, Murat; Aykanat, Cevdet (2022-04-01)
HyGraph: a subgraph isomorphism algorithm for efficiently querying big graph databases Asiler, Merve; Yazıcı, Adnan; George, Roy (2022-04-01) The big graph database provides strong modeling capabilities and efficient querying for complex applications. Subgraph isomorphism which finds exact matches of a query graph in the database efficiently, is a challenging pr...
Targeting HIF1-alpha/miR-326/ITGA5 axis potentiates chemotherapy response in triple-negative breast cancer Assidicky, Ridho; Tokat, Unal Metin; Tarman, Ibrahim Oguzhan; Saatci, Ozge; Ersan, Pelin Gulizar; Raza, Umar; Ogul, Hasan; Riazalhosseini, Yasser; Can, Tolga; Sahin, Ozgur (2022-03-01) Purpose Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer that is frequently treated with chemotherapy. However, many patients exhibit either de novo chemoresistance or ultimately develop...
Event prediction from news text using subgraph embedding and graph sequence mining Çekinel, Recep Fırat; Karagöz, Pınar (Springer Science and Business Media LLC, 2022-2-28) Event detection from textual content by using text mining concepts is a well-researched field in the literature. On the other hand, graph modeling and graph embedding techniques in recent years provide an opportunity to re...
