Box Plot of Standalone and Stacking Model Accuracies for Binary Classification

Stacking Ensemble Machine Learning With Python

Stacking or Stacked Generalization is an ensemble machine learning algorithm. It uses a meta-learning algorithm to learn how to best combine the predictions from two or more base machine learning algorithms. The benefit of stacking is that it can harness the capabilities of a range of well-performing models on a classification or regression task and […]

Visualization of Stacked Generalization Ensemble of Neural Network Models

Stacking Ensemble for Deep Learning Neural Networks in Python

Model averaging is an ensemble technique where multiple sub-models contribute equally to a combined prediction. Model averaging can be improved by weighting the contributions of each sub-model to the combined prediction by the expected performance of the submodel. This can be extended further by training an entirely new model to learn how to best combine […]

Box Plot of Gradient Boosting Ensemble Tree Depth vs. Classification Accuracy

How to Develop a Gradient Boosting Machine Ensemble in Python

The Gradient Boosting Machine is a powerful ensemble machine learning algorithm that uses decision trees. Boosting is a general ensemble technique that involves sequentially adding models to the ensemble where subsequent models correct the performance of prior models. AdaBoost was the first algorithm to deliver on the promise of boosting. Gradient boosting is a generalization […]

Box Plot of Soft Voting Ensemble Compared to Standalone Models for Binary Classification

How to Develop Voting Ensembles With Python

Voting is an ensemble machine learning algorithm. For regression, a voting ensemble involves making a prediction that is the average of multiple other regression models. In classification, a hard voting ensemble involves summing the votes for crisp class labels from other models and predicting the class with the most votes. A soft voting ensemble involves […]
