Which of the following statement is NOT True about ensemble methods?
Group of answer choices
Ensemble methods can be used to improve model performance
Ensemble methods create multiple data mining models on multiple training sample
Ensemble methods may include bagging, boosting, random forest and hyperparameter tuning
Ensemble methods aggregate predictions from multiple data mining models
The statement that is NOT true about ensemble methods is:
b. Ensemble methods create multiple data mining models on multiple training sample.
Ensemble methods are a set of techniques that utilize multiple data mining models to improve predictive efficiency and/or statistical power. They combine a group of models in order to generate a single superior outcome. An example of ensemble learning involves creating several decision trees and combining their outputs to make a final prediction. Another example of ensemble learning is the use of bagging methods, boosting methods, or random forests.
The following are the uses of ensemble methods:
Ensemble methods can be used to improve model performanceEnsemble methods may include bagging, boosting, random forest, and hyperparameter tuningEnsemble methods aggregate predictions from multiple data mining models.The above options are true, but ensemble methods do not generate multiple models on multiple training samples; instead, they generate multiple models on the same training sample.
Hence the correct answer is "Ensemble methods create multiple data mining models on multiple training sample" is NOT true.
