Ensemble models in machine learning combine the decisions from multiple models to improve the overall performance. Simple guide for ensemble learning methods | Juhi - Towards Data Science

Ensemble learning is an approach where two or more modes are fit on the same data and the predictions from each model are combined. The objective of ensemble learning is to achieve better performance with the ensemble of models as compared to any individual model. This involves both deciding how to create models used in the ensemble and how to best combine the predictions from the ensemble members. Ensemble learning is a useful approach for improving the predictive skill on a problem domain and to reduce the variance of stochastic learning algorithms, such as artificial neural networks. Some examples of popular ensemble learning algorithms include: weighted average, stacked generalization (stacking), and bootstrap aggregation (Multiclassifiers; Ensembles and Hybrids; Bagging, Boosting, and Stacking). 14 Different Types of Learning in Machine Learning | Jason Brownlee - Machine Learning Mastery
