Background: Information about project tasks stored in Issue tracking systems (ITS) can be used for project analytics or process simulation. However, such issues must be classified beforehand. Considering the number of tasks stored in ITS, this task shall be done automatically. Aims: Our research aims to build an automatic recurring Jira issue classification model based on types and textual descriptions to enable the practical application of the model for software project planning and management. Method: We study a dataset from six industrial projects containing 9.6K tasks and augment it with an additional dataset of 91K task descriptions from other industrial projects to up-sample minority classes during training. We labeled the data using a semi-manual, active-learning-based method. We perform ten runs of 10-fold cross-validation for each project and evaluate classifiers using a set of state-of-the-art prediction quality metrics, i.e., Accuracy, Precision, Recall, F1-score, and MCC. Our machine-learning pipeline includes a Transformer-based sentence embedder (‘mxbai-embed-large-v1’) and an XGBoost classifier. We also study the impact of task-classification errors on project staffing issues. Results: The model automatically classifies software process tasks into 14 classes with MCCs ranging from 0.69 to 0.88. We built a confusion matrix that showed the most frequently confused task classes. We analyzed the consequences of classification errors. Conclusions: The study’s results enable the practical application of the software process model to analyze, plan, and manage software development projects. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2025.

Malware detection is one of the critical tasks of cybersecurity, especially considering the growing popularity of mobile devices. The integrity and security of mobile ecosystems rely on the capacity to identify malware quickly and precisely, as security hacks against these devices become increasingly frequent. Due to the requirement for massive volumes of data aggregation, traditional centralized machine learning (ML) techniques for malware detection face challenges with data sharing, computational complexity, and privacy. This research addresses these challenges by proposing a novel model, called "CNN-Fed", which is based on Convolutional Neural Networks (CNN) with Federated Learning (Fed). The main goal of this work is to create a global classifier for Android malware detection that is highly accurate and does not require centralised data aggregation. Using four benchmark datasets—Drebin, Malgenome, Kronodroid, and Tuandromd—the CNN-Fed model is trained across many clients in a federated setting under the suggested architecture. Then we use multi-criteria decision-making (MCDM) methodology to evaluate the number of clients and number of rounds. We use two MCDM methods such as Entropy methodology to compute the criteria weights and the CoCoSo methodology to rank the alternatives. We use the interval-valued neutrosophic sets (IVNSs) to deal with uncertainty and vague information. We use five criteria such as accuracy, F1-score, precision, recall, and FP and six of alternatives refer to the number of clients and number of rounds. The results show the best alternative has a larger number of clients and rounds. © 2025, University of New Mexico. All rights reserved.

In this work, a novel methodological approach to multi-attribute decision-making problems is developed and the notion of Heptapartitioned Neutrosophic Set Distance Measures (HNSDM) is introduced. By averaging the Penta-Partitioned Neutrosophic Distance Measures under particular conditional criteria, the suggested technique ranks the options. Additionally, we explore the fundamental characteristics of HNSDM and provide several illustrative theorems. The Heptapartitioned Neutrosophic Set Distance Measures are formulated based on the Hepta Neutrosophic Set. Lastly, a practical numerical example is provided to illustrate the efficacy of the suggested methodology. © 2025, University of New Mexico. All rights reserved.

A Novel 3D Paradigm for Target Expansion of Augmented Reality SSVEP

引用

IEEE Transactions on Neural Systems and Rehabilitation Engineering 2025年 33卷 1562-1573页

Steady-State Visual Evoked Potentials (SSVEP) have proven to be practical in Brain-computer Interfaces (BCI), particularly when integrated with augmented reality (AR) for real-world application. However, unlike conventional computer screen-based SSVEP (CS-SSVEP), which benefits from stable experimental environments, AR-based SSVEP (AR-SSVEP) systems are susceptible to the interference of real-world environment and device instability. Particularly, the performance of AR-SSVEP significantly declines as the target frequency increases. Therefore, our study introduced a 3D paradigm that combines flicker frequency with rotation patterns as stimuli, enabling expansion of target sets without additional frequencies. In the proposed design, in addition to the conventional frequency-based SSVEP feature, bio-marker elicited by visual perception of rotation was investigated. An experimental comparison between this novel 3D paradigm and a traditional 2D approach, which increases targets by adding frequencies, reveals significant advantages. The 12-class 3D paradigm achieved an accuracy of 76.5% and an information transfer rate (ITR) of 70.42 bits/min using 1-second EEG segments. In contrast, the 2D paradigm exhibited a lower performance with 72.07% accuracy and 62.28 bits/min ITR. The result underscores the 3D paradigm’s superiority in enhancing the practical applications of SSVEP-based BCIs in AR settings, especially with shorter time windows, by effectively expanding target recognition without compromising system efficiency. © 2001-2011 IEEE.

Journal of The Institution of Engineers (India): Series B 2025年第2期106卷 459-473页

Indra Department of Computer Science and Engineering RMK College of Engineering and Technology Puduvoyal Thiruvallur India Department of Computer Science and Engineering RMD Engineering College Chennai India Department of Computing Technologies School of Computing Faculty of Engineering and Technology SRM Institute of Science and Technology Tamil Nādu Kattankulathur Chennai India School of Computer Science and Engineering Vellore Institute of Technology Chennai India

The increasing use of cloud-based image storage and retrieval systems has made ensuring security and efficiency crucial. The security enhancement of image retrieval and image archival in cloud computing has received considerable attention in transmitting data and ensuring data confidentiality among cloud servers and users. Various traditional image retrieval techniques regarding security have developed in recent years but they do not apply to large-scale environments. This paper introduces a new approach called Triple network-based adaptive grey wolf (TN-AGW) to address these challenges. The TN-AGW framework combines the adaptability of the Grey Wolf Optimization (GWO) algorithm with the resilience of Triple Network (TN) to enhance image retrieval in cloud servers while maintaining robust security measures. By using adaptive mechanisms, TN-AGW dynamically adjusts its parameters to improve the efficiency of image retrieval processes, reducing latency and utilization of resources. However, the image retrieval process is efficiently performed by a triple network and the parameters employed in the network are optimized by Adaptive Grey Wolf (AGW) optimization. Imputation of missing values, Min–Max normalization, and Z-score standardization processes are used to preprocess the images. The image extraction process is undertaken by a modified convolutional neural network (MCNN) approach. Moreover, input images are taken from datasets such as the Landsat 8 dataset and the Moderate Resolution Imaging Spectroradiometer (MODIS) dataset is employed for image retrieval. Further, the performance such as accuracy, precision, recall, specificity, F1-score, and false alarm rate (FAR) is evaluated, the value of accuracy reaches 98.1%, the precision of 97.2%, recall of 96.1%, and specificity of 917.2% respectively. Also, the convergence speed is enhanced in this TN-AGW approach. Therefore, the proposed TN-AGW approach achieves greater efficiency in image retrieving than other existing

作者： Sawicki, Aleksander Faculty of Computer Science Bialystok University of Technology Bialystok Poland

In this paper, we present an approach to build a biometric system capable of identifying subjects based on gait. The experiments were carried out with a proprietary gait corpus collected from 100 subjects. In the data acquisition process, we used a commercially available perception neuron body suit equipped with motion sensors and dedicated to entertainment in the VR domain. Classification was performed using two variants of the CNN architecture and evaluated using cross-day validation. A novelty in the presented approach was the exploration of research areas related to the usage of synthetically generated samples. Experiments were conducted for two types of preprocessing—a low-pass filtering of the signals using a 3rd- or 1st-order Butterworth filter. For the first variant, the synthetic samples generated by the long short-term memory-mixture density network (LSTM-MDN) model allowed us to increase the F1-score from 0.928 to 0.966. Meanwhile, in the second case from 0.970 to 0.978 F1-score. © 2025 John Wiley & Sons Ltd.

Systems on time scales incorporate continuous- and discrete-time dynamical systems. They can serve as models of real systems from various areas. Positive systems on time scales are studied here in more detail. Such systems appear in biology, medicine and chemistry. The language of time scales allows for natural description of time discretization in continuous-time models. During such discretization some properties of the system may be lost, while other may be preserved. Invariance under discretization of positivity and uniform exponential stability is investigated, both for linear and nonlinear systems. One of the results says that if discretization preserves positivity of the system, then it also preserves uniform exponential stability. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The rapid proliferation of mobile devices has driven the integration of artificial intelligence (AI) technologies, making the efficient operation of complex deep learning models within resource-limited environments a critical challenge in AI. This study addresses this challenge by focusing on mobile applications and proposing a streamlined sentiment analysis model specifically tailored for English movie reviews. We begin by exploring the diverse applications of sentiment analysis in user feedback and public opinion monitoring, underscoring its growing significance. Subsequently, we provide an overview of the evolving landscape of related technologies. In our experiment, we utilize the bag-of-words model for data preprocessing, which we combine with a convolutional neural network (CNN) and dropout regularization to construct a lightweight model architecture. Through iterative parameter optimization, we successfully achieve a delicate balance between model performance and complexity. We trained the model on a dataset consisting of 20,000 samples and achieved an accuracy of 81.76% on a test set of 5,000 samples. Compared to traditional, more complex sentiment analysis models, our proposed approach significantly reduces computational demands, demonstrating its potential for practical deployment on mobile devices. © 2024 Copyright held by the owner/author(s).
