Efficient Approximation, Error Estimation, and Adaptive Computation for Randomly Perturbed Elliptic Problems
... We consider the problem of approximating the probability distribution for a quantity of interest computed from the solution of an elliptic problem with a randomly perturbed diffusion coefficient. We model the uncertainty using a piecewise representation that is suited to situations in which there is ...

... items per day and counting Y, the number of defective items. If 0 denotes the probability of observing a defective item, then Y has a binomial distribution, when the number of items produced by the line is large. In other words, we can assume that Y N B(rz, 0) with n = 10. However, 0 varies from day ...

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.
