Classrooms as Formal Contexts for Learningal processes. In many cases the model excludes several processes or scales which are believed to have less importance for the applications at hand. Even if the model is a perfect representation of reality, its solution will not describe reality unless we have perfect knowledge about the initial and

The focus will be on some highly nonlinear problems which cannot easily be solved using the representer method. Examples are given were instead, so-called direct minimization methods are used.

We will now derive the generalized inverse formulation for the combined parameter and state estimation problem starting from Bayes’ theorem. Further, the resulting Euler–Lagrange equations ar

Numa Markee,Silvia Kunitz,Olcay SertKF). They belong to a general class of so-called particle methods which use a Monte Carlo or ensemble representation for the pdfs, an ensemble integration using stochastic models to model the time evolution of the pdfs, and different schemes for conditioning the predicted pdf given the observations.

Many solution methods, e.g. gradient methods, search only for the minimum of the cost function, and do not provide information about the uncertainty of the solution. The uncertainty can be estimated using statistical sampling based on the Metropolis or hybrid Monte Carlo methods fr

Intercultural Teaching in the Polish Context01), the review by .. (2003), and the paper by . (2004), have developed “square root” implementations of the analysis scheme where the perturbation of measurements is avoided. The square root methods are intuitively very appealing but there are also some pitfalls as pointed out by . (2004) and .. (2
