error backpropagation algorithm1
... Since the weights are adjusted in proportion to the f’(net), the weights that are connected to the midrange are changed the most. Since the error signals are computed with f’(net) as multiplier, the back propagated errors are large for only those neurons which are in the steep thresholding mode. The ...

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.
