A boosted decision tree approach using Bayesian hyper-parameter optimization for credit scoring
TL;DR: A sequential ensemble credit scoring model based on a variant of gradient boosting machine (i.e., extreme gradient boosting (XGBoost) is proposed, which demonstrates that Bayesian hyper-parameter optimization performs better than random search, grid search, and manual search.

Examining the coordination between urbanization and eco-environment using coupling and spatial analyses: A case study in China
TL;DR: Wang et al. as discussed by the authors analyzed the temporal and spatial characteristics of the coordination of urbanization and eco-environment of 30 provinces in China from 2005 to 2015, using the method of coupling coordination degree model and global (local) spatial autocorrelation.
