Deep Learning with Softmax and SVM using Worst Omega Optimization for Multi-Class Financial Prediction
type: item
description: This study proposes a hybrid framework for multi-class financial prediction and portfolio optimization by integrating deep learning-based classification models with worst-case Omega optimization. The framework employs a neural network architecture combined with Softmax and multi-class Support Vector Machine (SVM) classifiers to categorize assets into low-, medium-, and high-return classes. These classifications are subsequently utilized to construct portfolios using a worst-case Omega optimization model that explicitly accounts for downside risk and uncertainty. The empirical analysis is conducted on two benchmark datasets, BSE 30 and DOW 30, using a rolling window approach. The results demonstrate that the SVM-based classification model outperforms the Softmax model in terms of class separability and stability across varying market conditions. Portfolios constructed using SVM-selected assets consistently achieve higher returns, lower volatility, and improved risk-adjusted performance, as evidenced by superior Sharpe, Sortino, STARR, and Omega ratios. Furthermore, the worst-case Omega optimization framework provides enhanced protection against extreme losses by effectively controlling tail risk, as reflected in lower Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR). Comparative analysis with equally weighted portfolios confirms the ability of the proposed framework to generate persistent excess returns across different risk-aversion levels. Overall, the study highlights the importance of combining accurate classification techniques with robust optimization methods for effective portfolio management. The proposed approach offers a flexible and reliable solution for decision-making in dynamic and uncertain financial markets.

Cancer Detection in Breast Histopathological Images Using Extremely Randomized Trees
type: item
description: This research aimed to develop an effective machine learning-based system for the automated detection of breast cancer using histopathological images, overcoming the limitations of manual examination. The study utilized a diverse dataset of 13,347 histopathological images from three secondary sources and one primary source. The inclusion of multiple image sources was intended to enhance the model’s versatility. Initially, images underwent pre-processing to reduce noise using a median filter and were converted to grayscale. Otsu's thresholding was then applied to enhance nucleus edges and reduce background noise. A recursive feature elimination algorithm was employed to reduce the initial 98 features to these 48 key ones, focusing on the area and shape of the nucleus, color-based features, and image texture. For classification, the Extremely Randomized Trees Classifier was used. The model was trained to classify images as benign or malignant. The results demonstrated high performance, with the model achieving an accuracy of 98.95%. Further evaluation revealed a sensitivity of 99.48%, indicating a low false negative rate. Specificity was 94.67%, correctly identifying benign cases. The model also achieved precision of 98.97% and recall of 99.48%, with a Kappa statistic of 97.62%, suggesting substantial agreement beyond chance. The ROC performance was 98.67%, indicating robust performance. This study highlights the potential of machine learning, specifically the Extremely Randomized Trees Classifier, for automated and accurate breast cancer detection from histopathological images. The high-performance metrics suggest the model can enhance diagnostic accuracy and assist pathologists in clinical decision-making.

Classification of Skin Lesions with Deep Features Based on SqueezeNet Using Machine Learning Methods
type: item
description: Early and accurate identification of skin lesions is one of the most important factors that improves treatment success in dermatological diseases. Deep learning and image processing algorithms can provide promising results in diagnostic processes by learning complex texture, pigment, and structural features that are difficult for the human eye to distinguish. In this study, a hybrid classification approach based on deep feature extraction and machine learning is proposed. A total of 1,763 dermoscopic images, including eight lesion classes, selected from the ISIC 2019 skin lesion dataset were used. Deep features were extracted using a pretrained SqueezeNet model and analyzed using a 10-fold cross-validation method. The extracted features were evaluated using Artificial Neural Network (ANN), K-Nearest Neighbor (KNN), Support Vector Machine (SVM), and Logistic Regression (LR) classifiers. Experimental results show that the proposed model achieved accuracy values ranging from 96.7% to 89.6% and F1-score values ranging from 96.6% to 89.5%, successfully classifying skin lesions. The KNN model showed relatively lower discrimination capability compared to the other models. All models achieved 100% accuracy in the BCC (Basal Cell Carcinoma) class, while ANN and LR models also classified the SCC (Squamous Cell Carcinoma) class without error. Among all classes, the lowest performance was observed in the DF (Dermatofibroma) class. This study demonstrates that high classification performance can be achieved in multi-class (8 classes) dermatological analysis using lightweight architectures without requiring computationally heavy deep learning models. However, further validation on larger and more diverse datasets is required before real-world clinical applicability can be considered.

Digital Twin for Cryogenic Ejector Systems: Integrating Advanced Machine Learning and Dynamic Modeling
type: item
description: This paper presents an integrated Digital Twin (DT) framework for cryogenic ejector systems designed for Boil Off Gas (BOG) management in Liquefied Natural Gas (LNG) applications. Building on prior experimental and numerical studies, the proposed DT improves both predictive accuracy and dynamic adaptability by coupling Physics Informed Neural Networks (PINNs) with a transient dynamic model. The PINN integrates compressible flow conservation laws into its loss function, ensuring physical consistency during learning. A dataset of 1000 operating points was analyzed, revealing that the primary pressure (Pp) is the dominant factor influencing the entrainment ratio (ER). A baseline linear regression achieved an R2 equal to 0.791, while the PINN increased predictive accuracy to an R2 equal to 0.98. The dynamic model simulates the transient response of the ejector to sudden variations in BOG load, demonstrating the DT capability to anticipate system instability and enable real time control. Together, these components create a physically interpretable and computationally efficient digital framework capable of supporting the design, optimization, and operation of cryogenic ejectors. The results highlight the potential of the proposed DT to enhance energy efficiency, reliability, and safety in LNG processing systems through intelligent, physics based decision making.

Convolutional Neural Network-Based Framework for the Detection of Tuberculosis
type: item
description: Tuberculosis (TB) remains a significant public health issue worldwide, especially in low- and middle-income countries, where access to accurate and rapid diagnostic tools is limited. Early diagnosis and treatment are essential to control spread and improve patient outcomes. Traditional TB diagnosis methods, such as sputum microscopy and culture, are time consuming and require specialized laboratory facilities. In this study, we explored the application of machine learning techniques in automating and enhancing TB detection, focusing on the analysis of chest radiograph images (X-ray). Hence, a Convolutional Neural Network-based framework is presented. The framework used advanced image preprocessing and augmentation techniques to enhance feature learning and mitigate data set imbalance to support early screening and clinical decision making. The system demonstrated high precision, correctly identifying 97% of normal chest x-rays and achieving a perfect 100% precision for TB cases, which means no false positives were recorded. In terms of recall, the model correctly detected all normal X-rays but misclassified 5% of TB cases as normal, resulting in a 95% recall for TB detection. The F1-score, which balances precision and recall, was 98% for both normal and TB cases, indicating strong classification performance. Additionally, the macro and weighted averages were both 98%, reflecting consistent and reliable model performance across different case distributions. The results indicate that the proposed CNN-based framework provides a robust, scalable, and cost-effective solution for automated TB detection, offering potential integration into computer-aided diagnostic systems.

description: In agriculture, plants play a vital role in sustaining both human life and the ecosystem. However, plant diseases significantly affect crop yield and quality, making early detection essential. In this study, a dataset consisting of 458 healthy and 435 diseased plant leaf images was used for classification. SqueezeNet and InceptionV3 deep learning architectures were employed for feature extraction, and machine learning models including Artificial Neural Network (ANN), K-Nearest Neighbors (KNN), Support Vector Machine (SVM) and Logistic Regression (LR) were used for classification. Model performance was evaluated using accuracy, precision, recall, F1-score, and confusion matrix metrics. The experimental results show that the InceptionV3-based models achieved higher classification performance compared to SqueezeNet with the LR classifier providing the best overall accuracy of 98.48%. This study provides a comprehensive comparison of deep learning architectures combined with traditional machine learning classifiers and demonstrates the effectiveness of hybrid approaches for plant disease detection. The findings contribute to the development of accurate and efficient systems for early plant disease diagnosis.

Deep Learning Based Classification of Real and Synthetic Animal Images
type: item
description: This study aims to develop a convolutional neural network (CNN)-based classification framework that can distinguish between synthetic and real animal images generated by the Stable Diffusion Turbo model. Additionally, this study will evaluate the performance of different network architectures for this task. The study employed a balanced dataset of 31,995 images, including 16,000 real images and 15,995 synthetic images generated by Stable Diffusion Turbo. The dataset includes eight animal categories: dogs, cats, cows, rabbits, horses, sheep, chickens, and elephants. All images were resized to 224 by 224 pixels, and standard preprocessing techniques were applied. During the classification stage, five pretrained convolutional neural network architectures were retrained using transfer learning, including MobileNetV2, DenseNet121, DenseNet169, DenseNet201, and NASNetMobile. Model performance was evaluated using accuracy, precision, recall, the F1 score, the area under the curve of the receiver operating characteristic, confusion matrices, and training time. The experimental results demonstrate that MobileNetV2 and DenseNet201 achieved the highest classification performance, with respective accuracy rates of 99.58% and 99.56%, and perfect area under the curve values. All DenseNet variants exhibited complete sensitivity in detecting synthetic images, whereas NASNetMobile showed substantially lower performance compared to the other models. These results suggest that synthetic images produced by diffusion-based generative models can be reliably identified when appropriately designed CNN architectures and balanced datasets are used. This provides a significant methodological contribution to the discrimination of synthetic versus real images, the detection of fake content, and the verification of visual authenticity.

Classification of Obesity Levels Using Machine Learning Algorithms
type: item
description: Obesity has become a critical public health issue on a global scale due to the serious comorbidities and economic burden it brings. The aim of this study is to develop an effective machine learning model that can accurately determine obesity levels based on data including individuals' demographic characteristics and dietary habits, and to compare the performance of tree-based ensemble learning algorithms and Artificial Neural Network (ANN) approaches. In this context, classification was performed using Random Forest, XGBoost, CatBoost, and ANN (Artificial Neural Network) algorithms based on the open-source “Obesity Dataset” obtained from 1,610 participants and containing 14 different attributes. The models' performance was tested using a 5-fold cross-validation method and evaluated based on accuracy, f-score, precision, and recall using a confusion matrix. Experimental results show that tree-based ensemble models outperform the ANN approach in this dataset. The Random Forest algorithm was the most successful model with an accuracy rate of 94.34% and an F-score of 94.36, followed by XGBoost with an accuracy rate of 92.80%. In contrast, YSA remained at an accuracy rate of 82.98% and spent approximately 93 times more time in terms of training duration compared to Random Forest. When considering the obtained outputs, this study demonstrates that ensemble learning methods such as Random Forest are more efficient than ANN models in terms of both prediction accuracy and computational cost in the analysis of tabular health data, and that the developed model can be used as a reliable tool in clinical decision support systems.

CrackNet: Pavement Crack Detection and Classification Based on Deep Learning Models
type: item
description: The identification of pavement cracks is essential for reducing traffic accidents and minimizing road maintenance costs. Existing crack detection methods frequently encounter challenges related to inefficiencies and accuracy, resulting in billions of dollars spent globally on road repairs annually. This study introduces an enhanced deep learning-based network aims at improving the accuracy of pavement crack detection. The proposed CrackNet utilizes advanced geometric augmentation techniques to enhance the model performance in identifying cracks across a variety of road conditions. We introduced CrackNet, a custom-designed deep-learning classification framework for pavement images. CrackNet combines pre-trained backbone feature extractors (MobileNetV2, InceptionV4, SqueezeNet) with a lightweight classifier head and a comprehensive preprocessing + augmentation pipeline to improve generalizability and address class imbalance. We evaluated three CrackNet variants (Sqz-CrackNet, Mob-CrackNet, Incep-CrackNet), each distinguished by its backbone, and found Incep-CrackNet achieved the highest accuracy of 96.05%, surpassing the Mob-crackNet and Sqz-crackNet, which attained accuracies of 95.44% and 90.06%, respectively. These findings underscore the effectiveness of the proposed deep learning framework in accurately detecting pavement cracks, representing a significant advancement over traditional detection methods.

A Fixed-Grid Rdtm-Based Computational Strategy for Nonlinear Partial Differential Equations
type: item
description: In this study, a fixed-grid version of the Reduced Differential Transform Method (RDTM) is systematically implemented to obtain approximate solutions of linear and nonlinear partial differential equations. In this method, the solution range is divided into equal subregions and the fixed-grid algorithm is integrated into the RDTM framework. This approach provides an efficient and orderly computational process for solving complex partial differential equations. The effectiveness of the proposed method is demonstrated on the homogeneous Klein–Gordon equation (a representative hyperbolic equation) and the nonlinear Klein–Gordon equation, and the obtained approximate solutions are compared with known analytical solutions with high accuracy and consistency. Furthermore, the proposed fixed-grid RDTM (FGS-RDTM) framework offers potential integration with intelligent systems where accurate and efficient numerical solvers are required for modeling, control, and learning in dynamic environments. These results confirm the reliability and practical usefulness of the new method in addressing nonlinear partial differential equations in the context of intelligent computational systems.

Dual-Scale Transformer-Guided Attention Network for Efficient Multi-OAR Segmentation in Head and Neck Radiotherapy
type: item
description: Accurate segmentation of organ-at-risk (OARs) in head and neck CT images is crucial for radiotherapy planning, but it remains a challenging task due to anatomical complexity, low soft-tissue contrast, and the presence of small, variable structures. We propose DSTANet, a novel dual-scale transformer-guided attention network that integrates multi-resolution encoding, transformer-based global context fusion, and anatomically guided attention refinement to deliver precise multi-OAR segmentation. Unlike traditional CNN-based methods, DSTANet effectively models long-range spatial dependencies while preserving high-resolution boundary detail. On the HNSCC-3DCT-RT dataset, DSTANet achieved a mean Dice Score of 97.5% and a mean 95th percentile Hausdorff Distance (HD95) of 2.32 mm, while on the MICCAI 2015 benchmark dataset, it achieved 90.0% Dice, which surpasses several state-of-the-art approaches both in terms of overlap and geometric accuracy. These results, combined with a sub-20-second inference time, establish DSTANet as a robust and clinically viable solution for automated head and neck OAR segmentation.

type: item
description: Metaheuristic algorithms are powerful methods used to solve large and complex optimization problems. Thanks to their flexibility, they provide effective results in various fields and also have an important place in security applications such as the Merkle-Hellman Knapsack Crypto System. Aquila Optimizer is an optimization algorithm inspired by the hunting behavior of aquilas. It provides fast and effective solutions to complex problems. In this study, Aquila Optimizer is discretized using taper-shaped transfer functions. Taper-shaped transfer functions help the algorithm obtain more precise and effective results by increasing its performance. Four BinAO versions obtained in this way were tested on the Merkle-Hellman Knapsack Cryptosystem. In the tests conducted for the cryptanalysis of "CAT" and "MACRO" messages, the version achieved more successful results. Additionally, tests conducted with the algorithms in the literature clearly showed that the proposed algorithm is successful and effective.

Object Detection and Visual Intelligence in Retail Environments: A Deep Learning Approach for Inventory and Behavior Analytics
type: item
description: The integration of visual intelligence technologies in retail environments has revolutionized inventory tracking and customer behavior analysis. This study proposes a comprehensive deep learning-based framework that leverages advanced object detection models to enhance retail operations through real-time visual insights. Our method integrates state-of-the-art architectures such as YOLOv8 and Mask R-CNN to accurately identify, track, and classify products on shelves while simultaneously analyzing shopper interactions and movement patterns. By utilizing annotated datasets collected from real-world retail scenarios, the system demonstrates high accuracy in both inventory status recognition and behavioral inference, outperforming traditional sensor-based methods.

Fusion-Aware Lightweight CNN with Channel-Wise Attention for Rose Leaf Disease Classification in Multispectral Color Domains
type: item
description: The rose plant holds significant economic and cultural value, not only as an ornamental species but also due to its widespread use across various industrial domains such as cosmetics, medicine, and perfumery. In this context, the early and accurate detection of leaf diseases is crucial for ensuring the healthy cultivation of rose plants. This study presents a novel approach that integrates image processing and deep learning techniques for the detection of common leaf diseases in rose plants. The proposed method utilizes the RoseNet dataset, which consists of three classes: Black Spot, Downy Mildew, and Fresh Leaf. Input images were converted into RGB, HSV, and YCrCb color spaces and then fused at the channel level to enhance spectral diversity and improve the model's learning capacity. The developed convolutional neural network (CNN) architecture was enriched with channel attention mechanisms, namely Squeeze-and-Excitation (SE) and Efficient Channel Attention (ECA) blocks. Class imbalance issues were addressed through class weighting and label smoothing strategies. The model's performance was evaluated using multiple metrics such as accuracy, precision, recall, and F1-score. Achieving an accuracy of 95.65%, the proposed model outperformed widely used CNN architectures in the literature. Furthermore, with a low parameter count (1.03M) and a fast test time (376 ms), the model is well-suited for deployment on embedded systems. The findings demonstrate that attention mechanisms are effective in enhancing class discrimination, particularly in low-sample-size datasets. Thus, the proposed model offers a reliable, cost-effective, and AI-based solution for the diagnosis of plant leaf diseases.

Implementation of a Heuristic Algorithm for the Solution of Discrete Time Cost Trade-off Problem
type: item
description: Time cost trade-off problem aims to minimize the total project cost by crashing the critical activities. This problem is solved by mathematical programming and meta-heuristic algorithms. However, construction sector has minimum priority on the theoretical knowledge to implement robust optimization algorithms. For this reason aforementioned optimization algorithms can be hardly implemented for the private construction companies. The nature of the time cost trade-off algorithm is not challenging and can be solved heuristically. In this study, a spreadsheet application is developed by utilizing in-app excel functions to identify the critical activities of the project and the paths of the project. The construction schedule is entered to the spreadsheet application as acticity on arrow diagram and the logical relationships between the activities are defined. Forward and backward pass computations are given as formulations which includes the actual activity durations. The developed application calculates the crashing costs of the critical activities and highlights the activities with the cheapest crashing costs. Prepaperd spreadsheet application implements a heuristic solution algorithm which is based on minimum cost slope of the construction activities. The user can easily execute the proposed or user selected crashing alternative and the schedule is updated according to the selection. The application is tested on 6 activity project and the optimum solution is obtained by crashing the activities sequentially. The proposed technique can be utilized to reduce the total project cost of the construction sector.

Realising Quality Control of Metal Products Used in Industry Through Deep Learning
type: item
description: This study was carried out with the aim of detecting the defects on the surfaces of metallic products, which are frequently encountered in our daily lives and widely used in industry, with deep learning. Many metal products in the industry undergo different processes during the production phase. As a result of these processes, the detection of defects such as breakage, cracking, etc. on the surfaces of metal products is carried out by quality control personnel or production personnel. However, this error detection made by manpower both slows down production and causes overlooked errors. In order to easily detect these defects, in our study, we used a dataset consisting of 285 images in total with images of two different surface defects and images containing flawless metal parts and a CNN architecture, ResNet50 architecture, to defects. There are three classes in total in the dataset. Two of these classes consist of images of different types of defects on the surface of the metal piston part used in air conditioners, and one of them consists of images of perfect metal piston parts. Convolutional Neural Network (CNN) method was used to determine the features of the images. Precision, recall, F1-Score and accuracy metrics were used to measure the performance of the model. With the ResNet50 architecture, defects on the surfaces of metal piston parts are detected quickly and with high accuracy. As a result of the study, it was suggested that the proposed model can detect surface defects that occur in the usage areas of metal products in various sectors more quickly and accurately using deep learning. This shows that the quality control problems experienced in the industry can be reduced by using deep learning, saving time and manpower.

Emotion Detection with Pre-Trained Language Models BERT and ELECTRA Analysis of Turkish Data
type: item
description: Developments in artificial intelligence have led to positive developments in many fields. Sentiment analysis, one of these areas, has become more applicable with the models and architectures developed. In this study, emotion detection and emotion analysis were performed on the transcribed data of Turkish voice recordings. In the emotion detection phase, after the emotional states (positive, negative, neutral) of the data were detected with BERT and ELECTRA models, which are transformer-based structures, machine learning algorithms were used in the accuracy analysis of these emotional states and the Google Colaboratory platform was used in the application phase. Naive Bayes, Random Forest, Support Vector Machine and Logistic Regression algorithms were used in the accuracy analysis. As a result of the study, both Naive Bayes and Logistic Regression algorithms achieved the best accuracy rate in emotion detection with the BERT model with a rate of 70%. In emotion detection with the ELECTRA model, both Random Forest and Logistic Regression algorithms achieved the best accuracy rate of 72%. BERT and ELECTRA methods are used to provide a better understanding of understanding and classification of emotional content in Turkish texts and contribute to the development of sentiment analysis-based applications. In addition, two Turkish emotion data sets were obtained, and by using more than one method in emotion analysis, our study has been a unique study in the field, allowing the analysis of the study to be done more effectively.
