expectation & maximization
Why Expectation and Maximization algorithm not used in Machine Learning while Gradient Descent algorithm used in Machine Learning?
I know that Newton Raphson, Expectation & Maximization, and Gradient Descent are all known to be optimization methods. Somehow, I wonder why Gradient Descent is chosen to be used in most of Machine Learning applications but I never heard that Expectation & Maximization or Newton Raphson algorithms have been applied.
