Introduction to Ensemble Learning

CONTENTSBOOSTINGBAGGINGSTACKING

We have several classifier that classify our data well, but not great, and we had like to combine them into a super classifier that classify our data very well. This discipline is called Ensemble learning.

Reason to combine many learners togetherEnsemble learning can improve the accuracy of machine learning models as it combines multiple models to make a final prediction. This can help to reduce the errors and biases present in individual modelsEnsemble l...
