Inference of Sequential Association Rules Guided by Context
... since the first expression imposes that if an invoice occurs, then a payment would also occurs in the future. Context-free grammars have been widely used to represent programming languages and more recently, to model RNA sequences [12]. The SPIRIT algorithm exploits the equivalence of regular expre ...

... the parametric approach in Ackerberg (2009). A serious limitation is that the analysis in FKRB assumes that the R grid points used in a finite sample are indeed the true grid points that take on nonnegative support in the true F0 (β). Thus, the true distribution F0 (β) is assumed to be known up to a ...

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.
