I did my undergrad at U. of Michigan, and my master's at NYU. I would highly recommend both programs, although there are many great ones out there. I probably have a list of ~30 schools that I think would be excellent for a master's in CS with a focus on machine learning (although it is worth considering a master's in Data Science, as this makes sense if ML is your primary interest).

I am happy to give more targeted advice on grad school. Please send me an email at andrew [at] mrdrozdov.com.
