Hello there. Glad to see that you have the interest in Artificial intelligence as artificial intelligence is going to be the very basic for all the technologies coming in the next few years.

Coming to what artificial intelligence is, it's as the name says when the artificial things start to have the intelligence i.e. machine are capable enough to take the decision. This can be seen in now a days day's most commonly in robotics and automobile industry where robots take decision to carry our the process.

Coming up with what to study,then let's start from very basic. Since the concept of artificial intelligence is based on Natural Language so the very first thing that comes is to know about the natural language processing. After that you need something that can help the machine to use the intelligence which is being done by the Machine learning where you can make the machine learn from the past things. Now to work in all these technologies you firstly will need a programming language that can help you to write the code and interact with machine. For that the most suitable and commonly used language is Python.

So you should be starting with these and then you can get a better knowledge of what artificial intelligence can do.

And as for the source for study, you can refer to YouTube or can buy some course from some well established source like udemy Udacity Coursera, Ed x

Hello!

Artificial intelligence is simply the intelligence displayed by the machines. It is the way by which machines are taught to copy/behave like a human brain.

There are various courses online as well as offline for you to learn artificial intelligence. Various engineering fields have this as their subject in their syllabus.

You can check 'coursera' and see the various courses provided by them.
