The correct answer is D: Tune the csv_weight hyperparameter and the scale_pos_weight hyperparameter by using. F1 metric combines both precision and recall which is more suitable for unbalanced datasets.
Question
An ecommerce company has developed a XGBoost model in Amazon SageMaker to predict whether a customer will return a purchased item. The dataset is imbalanced. Only 5% of customers return items. A data scientist must find the hyperparameters to capture as many instances of returned items as possible. The company has a small budget for compute. How should the data scientist meet these requirements MOST cost-effectively?
