In this paper, we explored approaches that improve the performance of ensemble bagging classifiers for identifying the state of a computer system. The following algorithms are considered: Ensemble pruning, Advanced Voting Algorithms, Dynamic Voting Strategies, Confidence Calibration, Adaptation through Meta-Features and Meta-Learning, which allow improving the voting procedure of the bagging meta-algorithm. Artificial data was generated as initial data, which complicates the classification task and contains an increased amount of noise. In the Google Collab environment, software models of algorithms have been developed, and their quality has been assessed. It was found that the use of the Ensemble pruning and Adaptation through Meta-Features algorithm is the most qualitative. In addition, the Ensemble pruning algorithm reduces the number of basic ensemble classifiers, and, as a result, increases the efficiency of computer system identification. Based on the results of the study, a method for identifying a computer system was proposed through the integrated use of a bagging classifier and an optimization procedure based on the Ensemble pruning algorithm.

Fasttext is a powerful word representation method that creates word representations based on vectors of character n-grams. In this work, we propose a method that utilizes fasttext features for a novel feature engineering model for the spam detection problem. In the feature engineering method, the combination of average, mean of second derivative; mean peak and standard deviation of fasttext features are computed. Finally, tf-idf features are also considered for the modeling process. The success of each feature engineering technique is measured and reported. The combination of the five feature extraction methods, tested on two spam detection datasets, yielded promising results with an accuracy of 0.978 on e-mail spam detection and an accuracy of 0.986 on sms spam classification.

The widespread integration of robotic technology across diverse sector’s necessitates solutions that embody both adaptability and speed. However, existing systems often exhibit a trade-off between these attributes, lacking swift adaptability. This paper introduces a novel self-reconfiguration system that addresses this challenge. Employing a scissor mechanism for rapid adjustment and an intelligent binocular vision driven by computer vision and reinforcement learning algorithms, the proposed system facilitates swift reconfiguration while effectively managing workload. Real-time perception and understanding of the surroundings enable the robot to promptly identify optimal dimensions and adjust its configuration accordingly. This capability empowers the robot to rapidly respond to new tasks without manual intervention, thereby augmenting its versatility and agility. Experimental validation demonstrates the system’s adeptness in navigating passages of varying widths in under a second, underscoring the efficacy of our approach in training the robot to adeptly adapt to diverse environmental conditions.

The paper focuses on the problem of technical social engineering attacks that encompass the manipulation of individuals to reveal sensitive information, execute actions, or breach security systems. These exploits frequently capitalize on human psychology, trust, and a lack of vigilance to attain unauthorized entry to networks, systems, or data. In contrast to traditional social engineering tactics that center on psychological manipulation, technical social engineering attacks employ technological means and strategies to manipulate and beguile individuals. The paper presents an attempt to detect social engineering attacks. The approach utilized four machine learning algorithms (decision tree, random forest, K-nearest neighbor, and extreme gradient boosting). The analysis is centered on data collected from network hosts, which may serve as indicators of a potential social engineering attack. The empirical results demonstrated high detection accuracy. © 2023 IEEE.

Multimodal learning analytics have become increasingly important in enabling a deeper understanding of teaching and learning in educational research. However, in comparison to other multimodal learning data, there is a limited understanding of the trends within gaze learning data. To address this challenge, this study aims to identify latent topics in gaze learning data through topic modeling and scientometric analysis. We analyzed the abstracts of 573 peer-reviewed and conference proceeding papers that used gaze learning data, written in English, and published between 2008 and February 2024. The findings are as follows. First, three main topics were identified through topic modeling analysis: (learning analytics, multimodal learning, and inclusive learning). Second, the scientometric analysis revealed the structure in which diverse clusters in cited references and institutions are connected around the emerging topics. Based on these findings, the study would provide insights into research directions in both educational research and applications using gaze learning data. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

It has great importance to provide the highest accuracy from fingerprint identification and verification systems, which have a large number of biometric features. Fingerprint recognition systems are more widely utilized than other biometric feature recognition systems. For this reason, a fingerprint recognition system must be fast and reliable to realize the separation of the fake and live fingerprints and provide high accuracy. In this study fingerprint liveness detection system is presented using LivDet2015 dataset. SVM (Support Vector Machine), CNN (Convolutional Neural Network), CNN+SVM methods are used for classification and their performances are compared. Especially the classifying performance of CNN method is analyzed. Before the classification process is performed with SVM, edge enrichment, transformation and feature extraction steps are applied on images as preprocessing steps. The highest accuracy rate is obtained by using CNN-deep learning classifier. © 2022 IEEE.
