For classification problems, data scientists would use historical data with predefined target variables AKA labels (churner\/non-churner)  answers that need to be predicted  to train an algorithm. With classification, businesses can answer the following questions:<br \/>\n&#8211; Will this customer churn or not?<br \/>\n&#8211; Will a customer renew their subscription?<br \/>\n&#8211; Will a user downgrade a pricing plan?<br \/>\n&#8211; Are there any signs of unusual customer behavior?<br \/>\nReference: <a href=\"https:\/\/www.kdnuggets.com\/2019\/05\/churn-prediction-machine-learning.html\" title=\"External link\" rel=\"nofollow noopener\" target=\"_blank\">https:\/\/www.kdnuggets.com\/2019\/05\/churn-prediction-machine-learning&#8230;<\/a><\/div>\n<p><\/strong><\/span> <\/div>\n","protected":false},"excerpt":{"rendered":"<p>A Machine Learning Specialist is working with a large company to leverage machine learning within its products.
