As the name implies, the purpose of machine learning is to allow machines to have the ability to learn, understand, and comprehend things similar to human beings. Imagine how important it is for a patient's recovery if a computer can summarize and sum up a large number of cancer treatment records, and be able to give appropriate advice and advice to a physician. In addition to the medical field, financial s

Customer Churn
"Loss rate" is a business term that describes the customer's departure or stop payment of a product or service rate. This is a key figure in many organizations, as it is usually more expensive to get new customers than to retain the existing costs (in some cases, 5 to 20 times times the cost).
Therefore, it is invaluable to understand that it is valuable to maintain customer engagement because it is a reasonable basis for developing retention policies and implementing operational
