IEEE Xplore - The expectation-maximization algorithmMoon, T K
1 in the context of gene frequency estimation, the expectation maximization algorithm was analyzed more generally by Hartley2 and by Baum et al.3 in the context of hidden Markov models, where it is commonly known as the Baum-Welch algorithm. The standard reference on the expectation maximization...

This article presents two new methods for non-negative VCE that utilize the expectation maximization algorithm for the partial errors-in-variables model. The former searches for the desired solutions with unconstrained estimation criterion and concludes statistically that the variance components have indeed...
Rather than picking the single most likely completion of the missing coin assignments on each iteration, the expectation maximization algorithm computes probabilities for each possible completion of the missing data, using the current parameters θ?(t). These probabilities are used to create a weighted...
In this lecture we show how to performmaximum likelihood estimationof a Gaussian mixture model with theExpectation-Maximization (EM) algorithm. At the end of the lecture we discuss practically relevant aspects of the algorithm such as the initialization of parameters and the stopping criterion. ...

Admittedly, going through the entire algorithm is beyond the scope of this post, but hopefully you’ll see how this powerful technique can be used to examine the effects of noise in your circuits. There is a great tutorial of expectation maximization from a 1996 article in IEEE Jour...
