Sperm cells contain two types of chromosomes: X and Y. The sex of a child is determined by the sperm cell that fertilizes the egg containing an X or Y chromosome. The X chromosome decides the female gender, while the Y chromosome determines the gender man. To determine the type of chromosome, the process of classifying the types of chromosomes contained in sperm cells is carried out. Developing a system for classifying X and Y chromosomes using the Convolutional Neural Network (CNN) algorithm aims to classify sperm cells carrying X or Y chromosomes. This CNN algorithm was chosen because this algorithm is perfect for the object detection process in the image. The CNN algorithm in this study uses two kinds of epoch values, namely 10 and 20. And using three kinds of number of neurons, namely 16, 32 and 128. The highest accuracy obtained in testing the number of epochs is 10 and the number of neurons is 16, and the number of epochs is 20 and the number of neurons is 32, which is 75,36%. © 2022 IEEE.

Diabetes is a formidable ailment characterized by elevated glucose levels in the bloodstream. Hence, it can cause many complications if it remains untreated and unidentified. Machine learning algorithms play a crucial role in early-stage detection and prediction of diabetes. This research aims to enhance the accuracy of diabetes mellitus prediction by using several techniques within the realm of machine learning. In this regard, the Pima Indians Diabetes dataset was used. Then, different machine learning algorithms have been applied separately or using ensemble learning. As a result, Support Vector Machine achieved an accuracy of 77.89%. Moreover, an empirical assessment of ensemble learning methodology involving the voting classifier and Bagging is conducted alongside contemporary techniques and base classifiers. The ensemble approach demonstrates its prowess, with the voting classifier achieving a result of 90.11%. Notably, the Bagging Classifier emerges as the frontrunner, attaining a remarkable accuracy value of 96.69%. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

In the era of Industry 4.0, where digital transformation is crucial, developing advanced chatbot system becomes essential to revolutionize service management and bolstering business continuity. By leveraging Artificial Intelligence (AI) within such industrial frameworks, smartchatbots promise to streamline operations, ensure seamless customer interactions, and drive efficiency, thereby fortifying businesses in today's competitive landscape. This study presents an adaptable smart chatbot model designed to mimic and absorb the expertise of technical officers within a factory setting, responding to employee technical queries. This approach aims to alleviate the burden on technical personnel while enhancing response efficiency. Unlike traditional systems, this adaptive model benefits from continuous learning capabilities, enabling it to refine its responses over time based on new interactions and corrections made by technical officers. Furthermore, the chatbot's 24/7 availability and the collaborative feedback mechanism for evaluating its responses ensure that it not only meets but exceeds user expectations. Through detailed analysis and empirical evidence, we demonstrate how this chatbot significantly enhances work quality and operational continuity, setting a new benchmark for digital service management in the context of Industry 4.0. The results from conducting surveys among the technical officers regarding the chatbot's usefulness were overwhelmingly positive. All participants expressed high satisfaction, confirming that the implementation of such a smart chatbot model significantly reduces their load and enhances the user experience. © 2024 IEEE.

Knowledge Tracing (KT) aims to predict students' future performance on answering questions based on their historical exercise sequences. To alleviate the problem of data sparsity in KT, recent works have introduced auxiliary information to mine question similarity, resulting in the enhancement of question embeddings. Nonetheless, there remains a gap in developing an approach that effectively incorporates various forms of auxiliary information, including relational information (e.g., question-student, question-skill relation), relationship attributes (e.g., correctness indicating a student's performance on a question), and node attributes (e.g., student ability). To tackle this challenge, the Similarity-enhanced Question Embedding (SimQE) method for KT is proposed, with its central feature being the utilization of weighted and attributed meta-paths for extracting question similarity. To capture multi-dimensional question similarity semantics by integrating multiple relations, various meta-paths are constructed for learning question embeddings separately. These embeddings, each encoding different similarity semantics, are then fused to serve the task of KT. To capture finer-grained similarity by leveraging the relationship attributes and node attributes on the meta-paths, the biased random walk algorithm is designed. In addition, the auxiliary node generation method is proposed to capture high-order question similarity. Finally, extensive experiments conducted on six datasets demonstrate that SimQE performs the best among 10 representative question embedding methods. Furthermore, SimQE proves to be more effective in alleviating the problem of data sparsity. © 2024 Copyright held by the owner/author(s).

We present PGTNet, an approach that transforms event logs into graph datasets and leverages graph-oriented data for training Process Graph Transformer Networks to predict the remaining time of business process instances. PGTNet consistently outperforms state-of-the-art deep learning approaches across a diverse range of 20 publicly available real-world event logs. Notably, our approach is most promising for highly complex processes, where existing deep learning approaches encounter difficulties stemming from their limited ability to learn control-flow relationships among process activities and capture long-range dependencies. PGTNet addresses these challenges, while also being able to consider multiple process perspectives during the learning process. © 2024, CC BY-NC-ND.

Q-Rung Orthopair Fuzzy Sets-Enhanced FMEA for COVID-19 Risk Assessment

Informatica (Slovenia)

引用

Informatica (Slovenia) 2025年第1期49卷 81-92页

作者： Abdullah, Lazim Awang, Noor Azzah Qiyas, Muhammad Special Interest Group of Modelling and Data Analytics Faculty of Computer Science and Mathematics Universiti Malaysia Terengganu Kuala Nerus21030 Malaysia College of Computing Informatics and Mathematics Universiti Teknologi MARA Selangor Shah Alam40450 Malaysia Department of Mathematics Riphah International University Failsabad Campus Pakistan

Failure Modes and Effects Analysis (FMEA) is a widely used tool for risk analysis, primarily to identify risk factors affecting system quality. Due to the limitations of the traditional FMEA model, several recent models incorporating advanced fuzzy set extensions have been developed to enhance the reliability of risk assessment outcomes. However, most of these models limit expert flexibility in expressing preferences and often overlook the impact of unequal expert weights and the stability of risk ranking results. This study introduces a new FMEA model based on Q-Rung Orthopair Fuzzy Sets (Q-ROFSs), termed Q-ROFSs-FMEA. Q-ROFSs, an extension of intuitionistic fuzzy sets, introduce a new linguistic term. The Q-ROFSs-FMEA model considers the unequal weights of experts, enabling a dynamic representation of expert preferences. These weights and the linguistic evaluation of risk factors are integrated through an aggregation operator, facilitating consensus among experts. The model is applied to a case study on COVID-19 risk factors, revealing that ‘older age’ (risk priority number 0.000012) is the highest risk factor, while ‘gender’ (risk priority number -0.0037) is the lowest. It is found that the ranking of risk factors determined by the Q-ROFSs-FMEA model is obtained as FM1 FM3 FM6 FM4 FM5 FM7 FM8 FM2 . Furthermore, a comparative analysis indicates consistent ranking results across different models, demonstrating the reliability of the proposed model. The case study and comparative analysis validate the effectiveness and applicability of the Q-ROFSsbased risk assessment model. © 2025 Slovene Society Informatika. All rights reserved.
