A cоmpаny uses а stаcking ensemble tо predict custоmer churn. The base learners include a decision tree, a support vector machine, and a logistic regression model. During validation, the meta-learner discovers that the decision tree performs best for customers with short account histories, while logistic regression performs better for long-term customers. What is the main advantage of stacking in this situation?
