Part time PD Diplomas/ MTech/ MS in AI ML

Hi,

I have 2 years of software dev experience (B.Tech IT) and I'm looking for part-time PG Diplomas in AI/ML:

Offered directly by IITs/NITs/IIITs/BITS

With a proper institute-issued diploma

No third-party platforms like upGrad, Great Learning, Simplilearn

Preferably 1 year or less, for working professionals

Are there any such credible programs? Would really appreciate any leads. Thanks!

If any good part time MTech and MS degree are available then let me know.
