Salman Khan gloms together multiple trained models to solve a churn prediction problem:
Historically, this domain has leaned on traditional statistical models, including logistic regression and decision trees. These methodologies sift through historical customer data to identify indicators predictive of future service discontinuation. Although these methods have demonstrated resilience over time, their adequacy is increasingly being questioned. In this regard, ensemble learning emerges as a sophisticated alternative, offering enhanced precision and reliability in identifying potential customer attrition.
Ensemble learning, in turn, distinguishes itself by simultaneously employing multiple predictive models to refine accuracy. This article, thus, aims to elucidate how ensemble learning can revolutionize the approach to churn prediction: we will explore various techniques such as Random Forest, Gradient Boosting, and Stacking, illustrating their efficacy in predicting customer churn through pragmatic examples.
Read on for an introduction to ensemble learning and some high-level tips to keep in mind when ensembling.
