Solution
The main advantage of using bagging (Bootstrap Aggregating) for a regression problem instead of a simple learning algorithm is "More accurate prediction".
Here's why:
-
Bagging is an ensemble method that combines the predictions from multiple machine learning algorithms together to make more accurate predictions than any individual model. It reduces the variance of predictions by combining the result of multiple classifiers modeled on different sub-samples of the same data set.
-
Bagging helps to decrease the model's variance, unlike a single learning algorithm. By creating subsets of the original dataset and then aggregating the results, bagging helps to reduce overfitting, which in turn increases the accuracy of the prediction.
-
The other options like "Lesser complexity", "Faster execution", and "The requirement of the smaller training dataset" are not typically advantages of bagging. In fact, bagging can be more complex and slower due to the need to train multiple models. It also doesn't necessarily require a smaller training dataset - it creates subsets from the original
