Be able to learn the parameters of a mixture model using the Expectation-Maximization (E-M) algorithm 2 Unsupervised learning So far in this course, we’ve focused on supervised learning, where we assumed we had a set of training examples labeled with the correct output of the algorithm. We’re going to
