Understanding Machine Learning & Deep Learning

All email providers today offer a special mail category known as'Spam', but how does the email program figure out the criteria for this type of categorization? The answer lies in Machine Learning. It could also be based on certain specific/typical patterns of email releases or roll outs. So when you receive a spam email, machine learning algorithms at the backend enable the system to identify and sort such messages automatically, placing it in the Spam folder and saving you the annoyance of doing it yourself while keeping you safe online. I often receive emails that claim I have won the lottery.
