Customer Churn Prediction

  • Machine Learning Algorithm: Gradient Boosting Machines (GBM)
  • ML Library/Module: XGBoost, specifically the XGBClassifier class

Customer churn prediction, which aims to identify customers who are likely to stop using a product or service, is a common use case of machine learning in business. Gradient Boosting Machines (GBM) are often used in churn prediction for their high performance and flexibility.

In Python, XGBoost is a library that provides an efficient and flexible implementation of the GBM algorithm. The XGBClassifier class is used for classification tasks, such as predicting whether a customer will churn (leave) or not.
