WebMaximum Likelihood Estimation Lecturer: Songfeng Zheng 1 Maximum Likelihood Estimation Maximum likelihood is a relatively simple method of constructing an estimator for an un-known parameter µ. It was introduced by R. A. Fisher, a great English mathematical statis-tician, in 1912. Maximum likelihood estimation (MLE) can be … WebMaximum Likelihood Estimation is estimating the best possible parameters which maximizes the probability of the event happening. Let us see this step by step through an example. Then you will understand how maximum likelihood (MLE) applies to machine learning. Maximum Likelihood Estimation (MLE) – Example Problem:
