Abstract In this paper, an enhanced equilibrium optimization (EO) version named Levy-opposition-equilibrium (LOEO) is proposed to select effective features in network intrusion detection systems (IDSs). The opposition-based learning (OBL) approach applied by algorithm improve the diversity of population. Also, Levy flight method utilized escape local optima. Then, binary rendition called BLOEO employed feature selection IDSs. One main challenges IDSs high-dimensional space, with many irrelevant or redundant features. designed intelligently most informative subset empirical findings on NSL-KDD, UNSW-NB15, and CIC-IDS2017 datasets demonstrate effectiveness algorithm. This has acceptable ability effectively reduce number data features, maintaining a high accuracy over 95%. Specifically, UNSW-NB15 dataset, selected only 10.8 average, achieving 97.6% precision 100%.

An intelligent fault diagnosis model for bearings with adaptive hyperparameter tuning in multi-condition and limited sample scenarios

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Март 24, 2025

Abstract Bearing fault diagnosis under multiple operating conditions is challenging due to the complexity of changing environments and limited availability training data. To address these issues, this paper presents an advanced method using a hybrid Grey Wolf Algorithm (HGWA)-optimized convolutional neural network (CNN) Bidirectional long short-term memory (BiLSTM) architecture. The proposed model leverages CNN for extracting spatial features BiLSTM capturing temporal dependencies. Through HGWA, hyperparameters are efficiently optimized, achieving 100% diagnostic accuracy across four with CWRU dataset. Additionally, optimized CNN–BiLSTM demonstrated high when applied as pre-trained in new environments, even minimal not only improves performance but also enhances optimization efficiency, faster results within same time frame. This approach mitigates challenges manually tuning effectively addresses bearing constrained sample conditions, representing meaningful contribution field rolling diagnostics.
