(2005)
Department of Software Engineering was founded in 2005 as the first department in Ankara in Software Engineering. The recent developments in current technologies such as Artificial Intelligence, Machine Learning, Big Data, and Blockchains, have placed Software Engineering among the top professions of today, and the future. The academic and research activities in the department are pursued with qualified faculty at Undergraduate, Graduate and Doctorate Degree levels. Our University is one of the two universities offering a Doctorate-level program in this field. In addition to focusing on the basic phases of software (analysis, design, development, testing) and relevant methodologies in detail, our department offers education in various areas of expertise, such as Object-oriented Analysis and Design, Human-Computer Interaction, Software Quality Assurance, Software Requirement Engineering, Software Design and Architecture, Software Project Management, Software Testing and Model-Driven Software Development. The curriculum of our Department is catered to graduate individuals who are prepared to take part in any phase of software development of large-scale software in line with the requirements of the software sector. Department of Software Engineering is accredited by MÜDEK (Association for Evaluation and Accreditation of Engineering Programs) until September 30th, 2021, and has been granted the EUR-ACE label that is valid in Europe. This label provides our graduates with a vital head-start to be admitted to graduate-level programs, and into working environments in European Union countries. The Big Data and Cloud Computing Laboratory, as well as MobiLab where mobile applications are developed, SimLAB, the simulation laboratory for Medical Computing, and software education laboratories of the department are equipped with various software tools and hardware to enable our students to use state-of-the-art software technologies. Our graduates are employed in software and R&D companies (Technoparks), national/international institutions developing or utilizing software technologies (such as banks, healthcare institutions, the Information Technologies departments of private and public institutions, telecommunication companies, TÜİK, SPK, BDDK, EPDK, RK, or universities), and research institutions such TÜBİTAK.

Abstract

Çevrimiçi reklamcılıkta kritik öneme sahip tıklama oranı (CTR) tahmini için geleneksel yöntemler, kullanıcı tercihlerinin dinamikliği ve reklamların alakasını kapsamada zorlanırken, yeni stratejilerin keşfini başarılı olanlarla dengeli bir şekilde sağlayan Thompson Örnekleme gibi takviyeli öğrenme (RL) algoritmaları, etkili bir çözüm sunar. Bu araştırmada, gerçek dünya reklam izlenimleri ve tıklamalarını simüle etmek için özel bir OpenAI Gym ortamını ve kullanıcı tercihlerinin ve reklamların alakasının sürekli değişimini ele alan dinamik CTR'yi tahmin etmek için bir Thompson Örnekleme uygulamasını içeren yeni bir RL tabanlı yaklaşım sunuyoruz. Bulgular, Thompson Örnekleme'nin CTR tahmininde, diğer RL stratejilerinden yaklaşık \%10 daha yüksek bir güven seviyesi ile, üstün bir performans sergilediğini ve bu sayede çevrimiçi reklam seçim süreçlerinin önemli ölçüde gelişebileceğini, böylece daha yüksek CTR'ler ve potansiyel olarak reklam yayıncıları için artan gelir sağlayabileceğini öne sürüyor.
Click-through rate (CTR) prediction plays a vital role in online advertising, influencing advertisement display and advertiser cost. However, traditional methods struggle to encapsulate user preference dynamics and advertisement relevance. To address this limitation, reinforcement learning (RL) algorithms, such as Thompson Sampling, offer a promising solution by effectively balancing the exploration of new strategies with the exploitation of successful ones. In this research, we introduce a novel RL-based approach for CTR prediction which involves a custom OpenAI Gym environment to simulate real-world advertisement impressions and clicks, and an implementation of Thompson Sampling to estimate CTR dynamically, addressing the continuous evolution of user preferences and advertisement relevance. Results showed that Thompson Sampling demonstrated superior performance in CTR prediction, outperforming other RL strategies. Notably, the algorithm exhibited a confidence level nearly 10\% higher than other methods. Our findings suggest that leveraging RL algorithms, particularly Thompson Sampling, can significantly enhance online advertisement selection processes, leading to higher CTRs and potentially increased revenue for publishers.
