Finding the ideal portfolio requires navigation through market uncertainties, fluctuations and fundamentals. Hence, this paper explores strategies to develop a risk-category portfolio to suit investors while adhering to Shariah guidelines. The main goals are to determine distinct clusters of Shariah-compliant stocks for construction companies in Bursa Malaysia and to categorize the cluster of stocks using selected stock indicators. K-Means Cluster analysis was employed to segment the construction stocks. Data on indicators were assessed from a finance portal from 2022 to 2024. The findings revealed three different clusters. Cluster 1 has the highest stock price and market capitalization, making it the most stable and lucrative option for long-term investors. Cluster 2, which exhibited moderate risk investment, is ideal for investors prioritizing capital preservation. Cluster 3, with 56 stocks, displayed high volatility and lower prices, appealing to risk-tolerant investors seeking growth opportunities. Based on these findings, the study aims to support investors in making informed, ethical, and strategically sound decisions in line with Shariah principles.</span></p>2025-09-01T00:00:00+00:00Copyright (c) 2025 Applied Mathematics and Computational Intelligence (AMCI)https://ejournal.unimap.edu.my/index.php/amci/article/view/1507TPOT-MLP-SVM: Hybrid Model of Multilayer Perceptron with Support Vector Machines Based on Genetic Programming for Predictive Analysis2024-12-02T02:42:17+00:00Samaila Abdullahisabdullahi2023@student.usm.mySaratha Sathasivamsaratha@usm.my<p>Nowadays, the integration of machine learning has drawn significant attention due to its effectiveness and robustness. Automated machine learning (AutoML) has transformed the field of artificial intelligence by developing an effective model to solve predictive tasks. Despite the performance of the conventional model, there is a need for improvement to achieve a better and more effective model. In this paper, we proposed TPOT-MLP-SVM, a novel hybrid model to enhance model performance that leverages genetic programming (GP) by integrating multilayer perceptron and support vector machine to improve predictive scores and robustness. The proposed method utilizes GP to automatically search and optimize the structure and parameters of both MLP and SVM variables, thereby minimizing manual input and maximizing predictive performance. Lastly, a real dataset was used to train, test, and validate the proposed model using Python software. The performance was evaluated based on accuracy, precision, sensitivity, specificity, f1-score, and ROC-AUC. Experimental results on benchmark datasets demonstrate the effectiveness and better performance of TPOT-MLP-SVM over stand-alone MLP and SVM models and other hybrid techniques. Overall, TPOT-MLP-SVM is a potential tool for predictive analysis, as it integrates MLP and SVM in a single system guided by genetic programming for early medical diagnosis in healthcare.</p>2025-09-01T00:00:00+00:00Copyright (c) 2025 Applied Mathematics and Computational Intelligence (AMCI)https://ejournal.unimap.edu.my/index.php/amci/article/view/946Detection of Diabetic Retinopathy Using a Transfer Learning Approach with DarkNet192024-12-11T05:52:11+00:00Michael Tang Tangmichaeltang@uts.edu.myAbdulwahab Funsho Atandaabdulwahab@uts.edu.myHuong Yong Tingalan.ting@uts.edu.my<p class="AbstractText" style="margin-bottom: 12.0pt;"><span lang="EN-US">The early detection of diabetic retinopathy (DR) in fundus images is crucial for preventing vision loss in diabetic patients.

There are numerous factors that contribute to the formation of GDP. Hence, this research attempts to identify the best-fit panel model for GDP among selected countries in Southeast Asia and determine the significant factors influencing their GDP. The data used is the panel data that consist of GDP, Consumer Price Index (CPI), Unemployment Rate (UR) and population growth (POP) from 2003 to 2022 for Malaysia, Thailand, Indonesia, Brunei and Singapore. The methods of pooled, fixed and random effects models are employed. The fixed effects model reveals substantial impacts of variables like UR, POP, and CPI on GDP. The random effects model, validated through the Breusch-Pagan test, demonstrates superior adaptability to country heterogeneity. The Hausman test supports the random effects model as a more reliable framework than fixed effects.

The traditional approach to blood classification involves manual analysis by hematologists. This intensive work process takes time and sometimes requires immediate diagnosis for cases that can be fatal. Therefore, to streamline this process, deep learning and image processing techniques will be utilized. This project aims to address these challenges by developing a web-based expert system for the automatic classification of blood samples using High-Resolution Neural Networks (HRNet). Inspired by the HRNet architecture originally designed for computer vision tasks, the system maintains high-resolution representations throughout the classification process. An innovative approach connects high-to-low resolution convolution streams in parallel, facilitating the preservation of high-resolution information. The exchange of information across resolutions enhances the semantic richness and spatial precision of the resulting representations. The system is capable of classifying blood samples into seven distinct categories as mentioned earlier. The proposed web application streamlines the diagnostic process, offering a faster and more accurate classification of blood samples. By automating this critical task, it supports hematologists in making more efficient diagnoses and helps prevent the progression of conditions like CML into more dangerous and acute phases. The dataset used is divided into a ratio of 8:1:1, representing the training, validation, and testing datasets. The total number of images used for training, validation, and testing are 549, 66, and 75, respectively. Thus, the total image dataset used in this project is 690. The system is targeted to achieve an accuracy rate of 99.89\%, demonstrating its effectiveness in blood classification. The HemaClassify system utilizes a REST architecture, with the frontend developed using NextJS, TailwindCSS, and ShadCN UI, and the backend implemented with a Flask API and the HRNet model. MySQL is used for database management. The user interface (UI) has been evaluated through User Acceptance Testing (UAT) conducted by Medical Laboratory Technologists (MLT) and hematologists from Hospital UKM, ensuring the system meets the requirements and expectations of end-users. The UAT results indicate a high level of user satisfaction, with most users rating the system 4/5 or 5/5 for its usability and functionality. This project represents a significant advancement in the field of blood classification, contributing to more timely and precise diagnoses, which are essential for effective disease management and treatment.</div>2025-09-01T00:00:00+00:00Copyright (c) 2025 Applied Mathematics and Computational Intelligence (AMCI)https://ejournal.unimap.edu.my/index.php/amci/article/view/1376A Review of Convolutional Neural Network-Based Automatic Lane Detection Methods on the TuSimple Dataset2025-02-25T02:57:46+00:00Ilyasa Pahlevi Reza Yuliantoilyasapahlevi@gmail.comAchmad Abdurrazzaqrazzaq.ganesha@gmail.comEsa Prakasaesap001@brin.go.id<p>This review explores and compares various automatic lane detection methods, shedding light on their strengths, weaknesses, and advancements.
