Which of the following is a widely used and effective machine learning algorithm based on the idea of bagging?

A. Decision Tree
B. Regresion
C. Classification
D. Random Forest

Eplanation
The Correct Answer is D .

The Radom Forest algorithm builds an ensemble of Decision Trees, mostly trained with the bagging method.

Which of the following is a disadvantage of decision trees?

A. Factor analysis
B. Decision trees are robust to outliers
C. Decision trees are prone to the be overfit
D. None of the Above

Eplanation
The Correct Answer is C .

Allowing a decision tree to split to a granular degree makes decision trees prone to learning every point extremely well to the point of perfect classification that is overfitting.

Which of the following is a reasonable way to select the number of principal components "k"?

A. Choose k to be the smallest value so that at least 99% of the varinace is retained.
