A Survey of Online Failure Prediction Methods
... In summary, accurate online failure prediction is only the prerequisite in the chain and each of the remaining three steps constitutes a whole field of research on its own. Not devaluing the efforts that have been made in the other fields, this survey provides an overview of online failure predictio ...

Expectation–maximization algorithm
In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
