Hey Arun,

As you want to pursue BTech in the domain of artificial intelligence or data science you must choose the college which provide basically degree based on only this disciple. For example in UPES Dehradun, for this domain you need to choose BTech in computer science and engineering with specialisation in artificial intelligence, and this course include hell lot of subjects other than which we usually require for our desired subject.

While talking about Jain University (Bangalore), they do provide specialisation in these subjects under the name of BTech in computer science and engineering with these respective subjects.

And further talking about their NIRF ranking, they do depend upon many factors irrespective of just placements and campus.

You can also seek for some IIIT's(if possible) as they only provide specific curriculum related to the topics (which you want to pursue) rather than studying physics maths and chemistry all over again. 

Else you can join Jain University Bangalore.

• Jain University's NIRF ranking is 115 whereas NIRF ranking of UPES is 145.
• UPES is good only for petroleum and related branches. For branches other than petroleum it is like any other lower ranked private college.
• The median package at Jain university is around 6lpa whereas for UPES it around 4lpa.
