Improved random forest algorithm.
Published 2025“…Additionally, considering the imbalanced in population spatial distribution, we used the K-means ++ clustering algorithm to cluster the optimal feature subset, and we used the bootstrap sampling method to extract the same amount of data from each cluster and fuse it with the training subset to build an improved random forest model. …”

An improved Grey Wolf Optimization based heuristic initialization algorithm for feature selection in P2P lending default prediction
Published 2025“…In this research, the finding used Grey Wolf Optimization (GWO) algorithm for selecting feature. However, GWO had flaw, starting with suboptimal initial solutions, which were not often the best option. …”
