why converge to minimum algorithm if the estimator converges to a minimum, how do we know why is expectation maximization algorithm guaranteed to converge to a minimum, even local? why does an algorithm converge what converges the algorithm? why is expected maximization algorithm always local why is em algorithm reliable what is em algorithm can we tell if an algorithm converges to a minimum what is the purpose of em why converge to minimum what is the minimum algorithm used for machine learning when is em algorithm local why does em converge to a minimum why does the expectation maximization algorithm converge what is local minimum how does em algorithm work why is expectation maximisation algorithm why converge to minimum algorithm why is expected maximization algorithm converge to minimum
