such as the general EM strategy,as schemas.A schema combines a generic code fragment with explicitly speci,ed preconditions which describe the applicability of the code fragment. The second core element which makes automatic algorithm derivation feasible is the fact that we can use Bayesian networks...
Therefore, the variables θ = {ln a; ln b} constitute the parameters that need to be updated by the Bayesian algorithm. The PGV field is provided by the shake-map estimates at the centroid of each pipeline segment i, with a median PGV value and an error rate εi: $$\ln PGV_{...
12 We aimed to develop an algorithm to identify this subgroup of patients for clinical trial eligibility and for optimal prescription of therapies. Methods Study design This prospective study was done as a derivation cohort before validation in multiple global cohorts (named external validation cohorts...
[41] provides an easy-to-use algorithm and routine for calculating solar zenith and azimuth angles. Since now we have hourly GHI, DNI and DHI, Eq. (1) can be applied to each individual hour. For this purpose, Eq. (1) can be simplified to(3)IT=Incosθ+Id1+cosβ2+Iρs1-cosβ2...
This chapter provides a derivation of the Hessian of the error function E, which is required for the Bayesian evidence scheme of chapters 10 and 11. The derivation is based on an extended version of the EM algorithm, which allows the full Hessian to be decomposed into three additive ...
We derive an estimate-maximize (EM) formulation of a Bayesian super-resolution algorithm for reconstructing scattering cross sections from coherent images-this renders obsolete all past attempts to derive such a scheme. We extend the analysis to the case of simultaneous super-resolution and autofocus...
The expectation-maximization (EM) algorithm is well established as a computationaily efficient method for separable signal parameter estimation. Here, a new geometric derivation and interpretation of the EM algorithm is given that facilitates the understanding of EM convergence properties. Geometric ...
