Life history induces markedly divergent insect responses to habitat loss. [PDF]

open access: yesJ Anim Ecol
This study pioneers the use of deep learning to rapidly assess over 22,000 Amazonian insects, revealing life history‐dependent winners and losers from forest loss. It shows that terrestrial insects decline while aquatic insects thrive, with body size influencing dispersal, offering key insights for biodiversity conservation in tropical fragmented ...

[Retracted] A 3D‐2D Convolutional Neural Network and Transfer Learning for Hyperspectral Image Classification

open access: yesComputational Intelligence and Neuroscience, Volume 2021, Issue 1, 2021., 2021
As one of the fast evolution of remote sensing and spectral imagery techniques, hyperspectral image (HSI) classification has attracted considerable attention in various fields, including land survey, resource monitoring, and among others. Nonetheless, due to a lack of distinctiveness in the hyperspectral pixels of separate classes, there is a recurrent
