Abstract Flood quantile estimation at sites with little or no data is important for the adequate planning and management of water resources. Regional Hydrological Frequency Analysis (RFA) deals hydrological variables ungauged sites. Random Forest (RF) an ensemble learning technique which uses multiple Classification Regression Trees (CART) classification, regression, other tasks. The RF gaining...

Imbalanced domain learning aims to produce accurate models in predicting instances that, though underrepresented, are of utmost importance for the domain. Research this field has been mainly focused on classification tasks. Comparatively, number studies carried out context regression tasks is negligible. One main reasons lack loss functions capable focusing minimizing errors extreme (rare) valu...
