Question

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You are creating a new experiment in Azure Learning learning Studio. One class has a much smaller number of observations than the other classes in the training You need to select an appropriate data sampling strategy to compensate for the class imbalance. Solution: You use the Synthetic Minority Oversampling Technique (SMOTE) sampling mode. Does the solution meet the goal?

Explanation

SMOTE (Synthetic Minority Oversampling Technique) is specifically designed to handle class imbalance by generating synthetic samples for the minority class. Rather than simply duplicating existing minority samples, SMOTE creates new synthetic data points by interpolating between existing minority class observations. Azure Machine Learning Studio supports SMOTE as a sampling mode. This directly addresses the problem of one class having significantly fewer observations, making it a correct and appropriate solution.
