Understanding machine learning

What is machine learning does?  It Finds patterns in data and uses those patterns to predict the future.          EXAMPLES :  Detecting credit card fraud : You can use machine learning  detect credit card fraud, Suppose you have data about previous credit card transactions. You could find patterns in that data potentially  that allows you to detect when a new credit card transaction is likely to be fraudulent. Determining whether a customer is likely to switch to a competitor :  You could possibly find the patterns in the existing customer data that will help you do that Lots more What does it mean to learn ? Yes it's something like your own learning process.
