    Investigating Strain Rate Effects on Damage Mechanisms in Hybrid Laminated Composites Using Acoustic Emission
    (Elsevier Sci Ltd, 2025) Gulsen, Abdulkadir; Kolukisa, Burak; Etcil, Mustafa; Caliskan, Umut; Zafar, Hafiz Muhammad Numan; Demirbas, Munise Didem; Bakir-Gungor, Burcu
    Hybrid composites, which combine distinct fiber types such as carbon, basalt, and aramid, provide a synergistic balance of strength, stiffness, impact resistance, and energy dissipation, making them appealing for critical applications in aerospace, automotive, and other high-performance industries. Monitoring damage progression in these composites is vital for ensuring structural integrity and preventing catastrophic failures. Acoustic emission (AE) serves as a powerful, noninvasive technique for real-time structural health monitoring, capturing the transient stress waves generated when damage events occur. This study utilizes AE to examine the influence of strain rate on damage modes in carbon/basalt/aramid hybrid composites under three-point bending. An unsupervised feature selection based on Laplacian scores is employed to identify the most relevant AE features with damage modes, while SHapley Additive Explanations (SHAP) are used to evaluate the correlation between AE features and strain rates. The correlation analysis results indicate that peak frequency (PF) serves as a key indicator, demonstrating significant shifts at higher strain rates. Gaussian Mixture Model (GMM) clustering is used to analyze hybrid composites by examining clustered AE signals based on selected features identified through Laplacian scores, with Silhouette scores employed to determine the optimal number of clusters. This study highlights the role of AE in understanding fiber interactions and damage evolution, offering valuable insights into the mechanical performance and optimization of carbon/basalt/aramid hybrid composite structures.

    Evaluating the Impact of Sentiment Analysis on Deep Reinforcement Learning-Based Trading Strategies
    (Institute of Electrical and Electronics Engineers Inc., 2024) Etcil, Mustafa; Kolukisa, Burak; Bakir-Güngör, Burcu
    Portfolio optimization is a form of investment management that aims to maximize returns while minimizing risks. However, the inherent complexity and unpredictability of financial markets pose a challenge. Recent advancements in machine learning, particularly in deep reinforcement learning (DRL), offer promising solutions by enabling dynamic and adaptive trading strategies. This paper presents a comprehensive evaluation of three actor-critic-based DRL algorithms-Advantage Actor-Critic (A2C), Deep Deterministic Policy Gradient (DDPG), and Proximal Policy Optimization (PPO)-applied to portfolio optimization. These strategies were implemented in both sentiment-aware and non-sentiment-aware versions, allowing for a direct comparison of their performance. The sentiment-aware models incorporated sentiment analysis using FinBERT and knowledge graphs to measure market sentiment from financial news, while the non-sentiment-aware models relied solely on stock prices and technical indicators. Our comparative study demonstrates that incorporating sentiment analysis resulted in consistently superior risk-adjusted returns and portfolio resilience during market fluctuations compared to non-sentiment-aware strategies. © 2025 Elsevier B.V., All rights reserved.

    Enhancing Breast Cancer Detection With a Hybrid Machine Learning Approach
    (2024) Etcil, Mustafa; Güngör, Burcu; Güngör, V. Cagri
    Dünya Sağlık Örgütü (WHO) tarafından belirlendiği üzere, göğüs kanseri, son beş yılda 7.8 milyon yeni vakayla en yaygın kanser türlerinden biri olarak ön plana çıkmaktadır. Bu çarpıcı istatistik, gelişmiş tanı yöntemlerine olan acil ihtiyacı vurgulamaktadır. Bu bağlamda, mevcut çalışma, göğüs kanseri tespiti için lojistik regresyon modeli eğitim sürecini iyileştirmek amacıyla klonal seçim algoritması (CSA) ile parçacık sürü optimizasyonunu (PSO) yenilikçi bir şekilde birleştiren CSA-PSO-LR sınıflandırıcısını önermektedir. Bu araştırma, geniş çapta tanınan iki veri seti olan Wisconsin Diagnostik Göğüs Kanseri (WDBC) ve Wisconsin Göğüs Kanseri Veritabanı (WBCD) kullanılarak, performans değerlendirmesi için 10 kat çapraz doğrulama ve Bayes hiperparametre optimizasyonunu içeren katı bir değerlendirme protokolü uygulamaktadır. Ayrıca, çalışma, model eğitim süresini önemli ölçüde kısaltmayı amaçlayan CPU paralelleştirme stratejilerini tanıtmaktadır. Karar ağaçları, aşırı gradyan artırma, en yakın komşular, lojistik regresyon, rastgele ormanlar ve destek vektör makineleri gibi makine öğrenimi algoritmalarına karşı yapılan karşılaştırmalı analizler, CSA-PSO-LR sınıflandırıcısının tespit doğruluğu ve F1-ölçütü açısından üstün performans sergilediğini göstermektedir. Bu araştırma, göğüs kanserinin erken tespitine yönelik yenilikçi bir yaklaşım sunarak, daha etkili tedavi planlarının kolaylaştırılmasına ve hastaların hayatta kalma beklentilerinin artırılmasına katkıda bulunmaktadır.

    Breast Cancer Detection Using a New Parallel Hybrid Logistic Regression Model Trained by Particle Swarm Optimization and Clonal Selection Algorithms
    (Wiley, 2025) Etcil, Mustafa; Dedeturk, Bilge Kagan; Kolukisa, Burak; Bakir-Gungor, Burcu; Gungor, Vehbi Cagri
    Breast cancer is one of the most widespread kinds of cancer, especially in women, and it has a high mortality rate. With the help of technology, it is possible to develop a computer-aided method for the diagnosis of breast cancer, which is crucial for effective treatment. Recent breast cancer diagnosis studies utilizing numerous machine learning models were efficient and innovative. However, it has been observed that they may have problems such as long training times and low accuracy rates. To this end, in this study, we present a new classifier that utilizes a hybrid of the clonal selection algorithm (CSA) and the particle swarm optimization (PSO) algorithm for the training of the logistic regression (LR) model, which is named CSA-PSO-LR. The proposed method is evaluated using two publicly accessible breast cancer datasets, that is, the Wisconsin Diagnostic Breast Cancer (WDBC) database and the Wisconsin Breast Cancer Database (WBCD), with 10-fold cross-validation and Bayesian hyperparameter optimization techniques. Additionally, a CPU parallelization method is applied, which substantially shortens the training time of the model. The efficacy of the CSA-PSO-LR classifier is compared with state-of-the-art machine learning algorithms and related studies in the literature. Performance analysis indicates that the proposed method achieves 98.75% accuracy and 98.27% F1-score on the WDBC dataset, and 97.94% accuracy and 97.35% F1-score on the WBCD dataset. These results demonstrate the potential of the proposed method as an effective approach for improving breast cancer diagnosis.

    Enhancing breast cancer detection with a hybrid machine learning approach
    (Abdullah Gül Üniversitesi, Fen Bilimleri Enstitüsü, 2024) Etcil, Mustafa
    According to the World Health Organization (WHO), breast cancer is one of the most prevalent illnesses, with 7.8 million instances recorded in the previous five years. As such, it poses a serious threat to world health. This alarming statistic underscores the urgent necessity for enhanced diagnostic methods. Against this backdrop, the current study proposes a novel diagnostic model, the CSA-PSO-LR classifier, which innovatively combines the clonal selection algorithm (CSA) with particle swarm optimization (PSO) to refine the logistic regression model training process for breast cancer detection. This research employs two extensively recognized datasets: the Wisconsin Diagnostic Breast Cancer (WDBC) and the Wisconsin Breast Cancer Database (WBCD), putting into practice a strict evaluation procedure that assesses performance using Bayesian hyperparameter optimization and 10-fold cross-validation. Furthermore, the study introduces CPU parallelization strategies to significantly curtail the model training time. Comparative analyses against machine learning algorithms, encompassing decision trees, extreme gradient boosting, k-nearest neighbors, logistic regression, random forests, and support vector machines, demonstrate the CSA-PSO-LR classifier's superior performance in detection accuracy and F1-measure. This investigation contributes a groundbreaking approach to the early detection of breast cancer, potentially facilitating more effective treatment plans and enhancing patient survival prospects.
