• Sampling is a technique of creating samples by extracting data from a population based on certain criteria. Samples extracted by certain criteria should represent the distribution of the population as well as prevent bias caused by a class imbalance in the population.
• The generally used technique is the Synthetic Minority Oversampling Technique (SMOTE) for preventing bias caused by a class imbalance in the population. This technique prevents bias by generating new synthetic data similar to minority class data and adding them to the existing data.
