I want to study artificial intelligence course in future show what then should I have to take in BTech either CSE or ECE
It's better if you take Computer Science engineering. Because artificial intelligence needs a well enough knolwedge of programming and coding as well. You learn lots of languages and also computer organisation and architecture in your btech CSE syllabus.
So ya you must choose CSE. And for masters you can choose Aritificial intelligence stream.
