    Enhancement of standardized precipitation evapotranspiration index predictions by machine learning based on regression and soft computing for Iran's arid and hyper-arid region. by Saeid Bour, Zahra Kayhomayoon, Farhad Hassani, Sami Ghordoyee Milan, Ommolbanin Bazrafshan, Ronny Berndtsson

    Published 2025-01-01
    “…Initially, the standardized precipitation evapotranspiration index (SPEI) was calculated, and then using large-scale signals such as large-scale climate signals (the North Atlantic Oscillation, the Arctic Oscillation, the Pacific Decadal Oscillation, and the Southern Oscillation Index), along with climatic variables including temperature, precipitation, and potential evapotranspiration, predictions were made for the period of 1966-2014. Several new machine learning models including Least Square Support Vector Regression (LSSVR), Group Method of Data Handling (GMDH), and Multivariate Adaptive Regression Splines (MARS) were used for prediction. …”
