Quantitative Assessment of Drought Impacts Using XGBoost based on the Drought Impact Reporter. (arXiv:2211.02768v1 [cs.LG])

Under climate change, the increasing frequency, intensity, and spatial extent
of drought events lead to higher socio-economic costs. However, the
relationships between the hydro-meteorological indicators and drought impacts
are not identified well yet because of the complexity and data scarcity. In
this paper, we proposed a framework based on the extreme gradient model
(XGBoost) for Texas to predict multi-category drought impacts and connected a
typical drought indicator, Standardized Precipitation Index (SPI), to the
text-based impacts from the Drought Impact Reporter …
