A Copula Entropy‐Assisted Hierarchical Binary Swarm Intelligence Algorithm‐Enabled Feature Selection and Intrusion Detection for IoT Networks

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Feature selection (FS) is a critical preprocessing approach for enhancing the quality of feature sets in various real‐world applications. Due to diverse relationships among features in high‐dimensional data sets, various features exhibit differing levels of importance and correlation with the target, which makes it challenging to effectively ...

Fault Diagnosis of Power Transformer Based on Extreme Learning Machine Optimized by Improved Grey Wolf Optimization

Journal of Applied Science and Engineering
For power transformers, the gas content in oil is used as the fault input feature quantity, and the accuracy of diagnosis results is not satisfactory. The problem of low accuracy of optimized extreme learning machine (ELM) of grey wolf optimization (GWO)

Research on Nonuniform Ageing State Assessment of Oil‐Immersed Power Transformers Based on PCA–GWO–RF Algorithm

High Voltage, EarlyView.
ABSTRACT The condition assessment of oil–paper insulation is critical for oil–immersed power transformers, which are fundamental to the reliability of modern power systems. The primary limitation of traditional transformer ageing assessment lies in its macroscopic, whole‐unit approach, which fails to account for the localised effects of nonuniform ...

Hybrid coati–grey wolf optimization with application to tuning linear quadratic regulator controller of active suspension systems

Engineering Science and Technology, an International Journal
Vehicle suspension systems have become increasingly crucial for both driving safety and comfort. Active suspension systems can dynamically adjust suspension characteristics in real-time by introducing force into the system. Designing a controller for the

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

Journal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.

A Grey Wolf Optimizer for Text Document Clustering

Journal of Intelligent Systems, 2018
Abstract Text clustering problem (TCP) is a leading process in many key areas such as information retrieval, text mining, and natural language processing. This presents the need for a potent document clustering algorithm that can be used effectively to navigate, summarize, and arrange information to congregate large data sets.

Contrasting associations between parental coordination and breeding success in albatrosses across differing environmental contexts

Journal of Animal Ecology, EarlyView.
Our study demonstrates that the benefits of parental coordination in albatrosses are context‐dependent rather than universal. Coordinated parental care enhanced reproductive success in stable environments, but had little effect in variable environments, where individual flexibility may be more valuable.

Gough's Cave and biomolecular archaeology: a story of evolving interpretation Archéologie biomoléculaire à la grotte de Gough's Cave : une interprétation en constante évolution

Journal of the Royal Anthropological Institute, EarlyView.
Gough's Cave is a key archaeological site that has been at heart of British archaeology for the past century. Professor Chris Stringer, whom this special issue honours, has been a key figure in excavations and research projects at the site for many decades.
