In recent years, ensemble learning methods have become popular in landslide susceptibility mapping (LSM) with varying degrees of success. Within classifier concept, decision tree based learners such as random forest (RF) (i.e. forest) and rotation (RotFor) gained a great interest due to their robustness against conventional statistical methods. This study proposes canonical correlation (CCF), new member family, the prediction for Yenice district Karabuk Turkey. To test suitability CCF...

Increasing the accuracy of thematic maps produced through process image classification has been a hot topic in remote sensing. For this aim, various strategies, classifiers, improvements, and their combinations have suggested literature. Ensembles that combine prediction individual classifiers with weights based on estimated accuracies are strategies aiming to improve classifier performances. One recently introduced ensembles is rotation forest, which idea building accurate diverse by...
