The phenomenal rise in network traffic across various sectors, driven by advancements in network communication, has led to an explosion of connected devices. While internet-based service providers have enhanced smart environments, these environments remain highly vulnerable to security risks. Due to their resource- constrained nature, Internet of Things (IoT) systems rely on edge servers for processing. Cutting-edge machine learning algorithms have significantly improved the security of edge computing systems by enabling early intrusion detection. However, the dynamic nature of our society demands more sophisticated Network Intrusion Detection systems (NIDS) that can balance the challenge of managing the explosive growth of network traffic data with effectively responding to attacks. This paper proposes a novel NIDS that can train and learn from massive amounts of data in a centralized environment. To identify the best subset of features for improved data representation and classification, a bio-inspired algorithm, the Improved Firefly Optimization Algorithm (IFOA), is employed. Furthermore, a hyper-tuned Extremely Randomized Trees (ERT) attack detection model is developed to accurately identify malicious behavior while minimizing false positives. The experimental results demonstrate that the proposed approach achieves superior accuracy and execution speed compared to alternative solutions and its baseline versions. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

Teaching How to Select an Optimal Agile, Plan-Driven, or Hybrid Software Development Approach: Lessons from Enterprise Software Development Leaders

引用

Journal of information systems Education 2023年第2期34卷 148-178页

作者： Spurrier, Gary Topi, Heikki Department of Computer Information Systems Bentley University WalthamMA02452 United States

Over 20 years after introducing and popularizing agile software development methods, those methods have proven effective in delivering projects that meet agile assumptions. Those assumptions require that projects be small and simple in scope and utilize small, colocated teams. Given this success, many agile advocates argue that agile should replace plan-driven methods in most or all project contexts, including those projects that deviate significantly from agile assumptions. However, today’s reality is that a diversity of agile, plan-driven, and hybrid approaches continue to be widely used, with many individual organizations using multiple approaches across different projects. Furthermore, while agile advocates argue that the primary barrier to agile adoption is the inertia of traditional organizational cultures, there are, in fact, many rational motivations for utilizing plan-driven and hybrid methods based on individual project characteristics. For information systems students, this creates confusion in two ways: 1) understanding that there is no single best way to develop software in all circumstances but, rather, teams should choose an optimal project approach based on project characteristics, and 2) unpacking and analyzing the wide range of project characteristics – including multiple dimensions in functional requirements, non-functional requirements (NFRs), and team characteristics – that impact that choice. This paper addresses both sources of confusion by utilizing case studies from 22 interviews of enterprise software development leaders. The paper analyzes each case utilizing a "home grounds" model that graphically portrays key project characteristics and their impact on the optimal choice of software development project approach. © 2023, Journal of information systems Education.

Recent advancements in computer science and engineering have significantly boosted interest in and success rate of speech recognition systems. Sophisticated speech recognition systems are being developed for a variety of languages having wide-spread applications. Arabic being one of the most widely used languages in the world, augmented by religious importance, is a potential candidate in this domain, however rich vocabulary and multiple dialects open up new challenges for development of Arabic speech recognition processes. This paper focuses on development of an Arabic isolated speech recognition system for the vocabulary of Holy Quran using Mel frequency cepstral coefficients and deep neural networks. The proposed system is capable of identifying individual words from a recited verse with reasonable accuracy. It targets the 362 unique words of the first and the last 19 chapters of the Holy Quran and uses 14 hours of audio data to demonstrate the working prototype of the system. A user-friendly, web-based application has also been developed for transcription of recitations. The software is specified to make an effort in spreading the right way of recitation of the Holy Quran. The presented architecture can be extended to a complete automatic speech recognition system to help people practice recitations, mapping speech to transcription and then matching the transcribed utterance with standard templates of correct recitation to identify reciter’s short comings. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

Alzheimer’s Disease is a progressive neuro-degenerative disorder and a leading cause of dementia, marked by cognitive decline, memory loss, and behavioral changes. Despite advancements in medical imaging and Artificial Intelligence (AI), early detection and accurate prognostic modeling remain challenging, particularly in distinguishing overlapping disease stages. This study proposes a novel AI framework combining EfficientNetB0, a state-of-the-art deep learning model, with dual attention mechanisms for robust feature extraction and survival analysis using the Alzheimer’s MRI dataset hosted on the Kaggle platform. The model was trained and evaluated on a balanced dataset of 6,400 MRI images, classified into 4 AD stages: Non-Demented (NoD), very Mild-Demented (vMiD), Mild-Demented (MiD), and Moderate-Demented (MoD). The pre-processing steps, including resizing, normalization, and data augmentation, ensured robustness and generalizability. The framework achieved classification accuracies of 99. 93% (training), 93. 60% (validation) and 93. 59% (testing), with a perfect Concordance Index of 1.0 for survival predictions, demonstrating its ability to accurately rank survival times. By integrating survival analysis with deep learning, the framework addresses limitations in previous work, such as reliance on linear assumptions and limited classification capabilities, and provides actionable insights for clinical workflows, supporting personalized treatment and early intervention strategies. Future work will focus on integrating longitudinal data, exploring time-dependent co-variates, and enhancing explainability to promote adoption in diverse clinical settings. This approach represents a significant advancement in AI-driven diagnosis and progression modeling of AD, with the potential to transform patient care and outcomes. © 2013 IEEE.

This research explores the efficacy of various machine learning models in detecting network threats, focusing on their performance across known, similar, and new attack datasets. I evaluated models including Random Forest, XGBoost, Logistic Regression, and Gaussian Naive Bayes, utilizing different preprocessing pipelines such as scaling, PCA, and correlation-based feature selection. Our findings reveal that while most models achieve near-perfect performance on known and similar threats, their ability to generalize to new threats is limited, with Gaussian Naive Bayes showing the highest F1 score on new attacks. Furthermore, Logistic Regression and Gaussian Naive Bayes models demonstrate the fastest detection times. The study highlights the importance of preprocessing techniques and model selection in enhancing threat detection systems. Deployment strategies for these models are discussed, emphasizing potential online and offline applications. Despite achieving significant insights, the study acknowledges the limitations posed by dataset size and computational resources, suggesting areas for future improvement. © 2024 IEEE.
