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 ...

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 ...

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.
