By Jason Brownlee on April 27, 2021 in Ensemble Learning 133. 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 …

Model blending -- by which I mean creating multiple sets of predictions from models that have the same dependent variable and the same or similar independent variable candidates, as opposed to model stacking -- is a popular way of creating ensembles of Machine Learning models. For example: Y = regression_predictions * .5 + tree_predictions * .5.

In conclusion, blending is an effective and straightforward ensemble technique in machine learning that offers several advantages. By combining the predictions of multiple base models, blending can …

In summary, we attempted to extend the transferability of any pretrained machine learning model across different databases by introducing the concept of feature blending. Feature blending is shown to enable the selection of features with global relevance in contrast to local scope offered by individual class features, by iteratively mixing and ...

Graph machine learning has been extensively studied in both academic and industry. However, as the literature on graph learning booms with a vast number of emerging methods and techniques, it becomes increasingly difficult to manually design the optimal machine learning algorithm for different graph-related tasks.
