High performing ensemble of convolutional neural networks for insect pest image detection

no code implementations28 Aug 2021 Loris Nanni, Alessandro Manfe, Gianluca Maguolo, Alessandra Lumini, Sheryl Brahnam

The best performing ensemble, which combined the CNNs using the different augmentation methods and the two new Adam variants proposed here, achieved state of the art on both insect data sets: 95. 52% on Deng and 73. 46% on IP102, a score on Deng that competed with human expert classifications.

Comparison of different convolutional neural network activation functions and methods for building ensembles

no code implementations29 Mar 2021 Loris Nanni, Gianluca Maguolo, Sheryl Brahnam, Michelangelo Paci

Because activation functions inject different nonlinearities between layers that affect performance, varying them is one method for building robust ensembles of CNNs.

Neural networks for Anatomical Therapeutic Chemical (ATC) classification

no code implementations22 Jan 2021 Loris Nanni, Alessandra Lumini, Sheryl Brahnam

Motivation: Automatic Anatomical Therapeutic Chemical (ATC) classification is a critical and highly competitive area of research in bioinformatics because of its potential for expediting drug develop-ment and research.
