Management has hired a team of writers to create additional targeted content. A data scientist needs to identify five customer segments based on age, income, and location. The customers&#039; current segmentation is unknown. The data scientist previously built an XGBoost model to predict the likelihood of a customer responding to an email based on age, income, and location.<br \/>\nWhy does the XGBoost model NOT meet the current requirements, and how can this be fixed?<br \/><strong><br \/>A.<\/strong> The XGBoost model provides a true\/false binary output. Apply principal component analysis (PCA) with five feature dimensions to predict a segment.<br \/><strong>B.<\/strong> The XGBoost model provides a true\/false binary output. Increase the number of classes the XGBoost model predicts to five classes to predict a segment.<br \/><strong>C.<\/strong> The XGBoost model is a supervised machine learning algorithm.
