imbalanced-ensemble, abbreviated as imbens, is an open-source Python toolbox for leveraging the power of ensemble learning to address the class imbalance problem. It provides standard implementations of popular ensemble imbalanced learning (EIL) methods with extended features and utility functions. These...
The scikit-learn Python machine learning library provides an implementation of Gradient Boosting ensembles for machine learning. The algorithm is available in a modern version of the library. First, confirm that you are using a modern version of the library by running the following script: 1 2 3...
bagging,boosting,Blending,Stacking,四者都属于集成方法(Ensemble Learning) 集成方法的目标是把多个使用给定学习算法构建的基估计器的预测结果结合起来,从而获得比单个估计器更好的泛化能力/鲁棒性. 一.Bagging Bagging即套袋法 (一).Bagging的算法原理: bagging的个体弱学习器的训练集是通过随机采样得到的。通过T次的...
We propose a new supervised learning algorithm, for classification and regression problems where two or more preliminary predictors are available. We introduce exttt{KernelCobra}, a non-linear learning strategy for combining an arbitrary number of initial predictors. exttt{KernelCobra} builds on the ...
