What is machine learning?

Machine learning gives computers the ability to learn without being explicitly programmed. It is the ability for computer programs to analyse data, extract information automatically, and learn from it.

So basically implementing machine learning means creating algorithm which can learn and make predication on data.

What is Machine Learning

Some examples of machine learning:

·       Amazon recommendations based on the customers browsing and purchasing behaviour.

·       Googles search engine, that rank the websites by relevancy.

·       Self-driving cars

·       Email spam filters.

All of the systems above learn and improve themselves as more and more data is provide:

The more you search and purchase on amazon, the better recommendations it gives. The more emails you mark as spam the better the system filters new emails. The more situations the self-driving car navigates, the better it drives.

This is very similar to how we humans learn. A typical example is the problem of classification. For instance, the email spam filter needs to classify the spam and not spam emails. Note that this is quite user dependent if we know that a specific user is marking all the travel emails as spam we are going to classify the new emails more effectively more relevant data leads to better predictions.
