Ensemble, Fusion, Combining#

Ensemble learning, fusion, and combining are techniques used in machine learning to improve the performance and robustness of models by leveraging:

  • multiple models

  • many types of data sources

  • multiple learners

Some Methods#

There are several methods for creating ensembles:

  • Bagging (Bootstrap Aggregating): Multiple models are trained on different random subsets of the training data.

  • Boosting: Models are trained sequentially, with each new model focusing on correcting the errors made by previous models.

Model Fusion

  • Voting

Simplicity and Diversity#

DiversitySymbol

  • Simplicity: Use simple models that are easy to interpret and less prone to overfitting.

  • Diversity: Ensure that the models are different from each other in terms of their predictions and error patterns. In quran:

Bayesian combination, is indeed a prominent technique among ensemble methods. It leverages Bayesian inference principles to combine predictions from multiple models or experts, incorporating uncertainty and prior knowledge to improve overall predictive accuracy and reliability.
