Model ensemble techniques of machine learning algorithms for soil moisture constants in the semi‐arid climate conditions

open access: yesIrrigation and Drainage, Volume 74, Issue 2, Page 529-540, April 2025.
Abstract In recent years, the use of prediction models based on intelligent algorithms has become widespread in soil science. However, each algorithm has advantages and disadvantages, and variable results can occur on different datasets. The evaluation of ensemble techniques for solving these problems is the current approach.

Why are there so many definitions of eutrophication?

open access: yesEcological Monographs, Volume 94, Issue 3, August 2024.
Abstract Because of the first observations in the 1900s of the oligotrophic and eutrophic states of lakes, researchers have been interested in the process that makes lakes become turbid because of high phytoplankton biomass. Definitions of eutrophication have multiplied and diversified since the mid‐20th century, more than for any other ecological ...
