A Novel Artificial Neural Network (ANN) Using The Mayfly Algorithm for Classification

open access: yes2021 International Conference on Digital Futures and Transformative Technologies (ICoDT2), 2021
Training of Artificial Neural Networks (ANNs) have been improved over the years using meta heuristic algorithms that introduce randomness into the training method but they might be prone to falling into a local minima in a high-dimensional space and have

Mayflies of the Bednja River, Croatia

open access: yesNatura Croatica, 2022
Here we present the results of a mayfly study conducted on a hydromorphologically altered lowland river in Croatia, the Bednja River. Twenty-two mayfly species were recorded, Baetis fuscatus (Linnaeus, 1761) and Serratella ignita (Poda, 1761) being the most widespread and Paraleptophlebia submarginata (Stephens, 1836) and Cloeon dipterum (Linnaeus ...
