CS Grad courses

So Im not in jersey anymore which forces me to take the grad courses on web campus(unless yall know professors that lowkey do both). Which only leads to a few options. Machine learning with David Landaeta, Text Mining and Information Retrieval with Xueqing Liu, and artificial intelligence (no professor yet). I know crazy pool of classes. I refuse to take a duggen class. Let me know what yall think about these three. I'm leaning on machine learning but i dont want to do any math and never heard of this professor before.
