Abstract For banks, credit lines play an important role exposing both liquidity and risk. In the advanced internal ratings-based approach, banks are obliged to use their own estimates of exposure at default using conversion factors. volatile segments, additional downturn required. Using world's largest database defaulted from US Europe macroeconomic variables, we apply a Bayesian mixed effect q...

The increasing complexity of tasks addressed by humanoid robotics requires accurate mechanical models which are difficult to obtain in practice. One approach is to let the robot learn its own models. In [16], two algorithms were compared on learning the velocity kinematics model of iCub: XCSF and LWPR. This comparison was based on simulated data. In this paper, we propose to extend this study t...

A combination of recursive least squares and weighted least squares is made which can adapt its structure such that a relation between inand output can he approximated, even when the structure of this relation is unknown beforehand. This method can adapt its structure on-line while it preserves information offered by previous samples, making it applicable in a control setting. This method has b...

A standard approach in presenting the results of a statistical analysis of regression data in scientific journals is to focus on the question of statistical significance of regression coefficients. The reporting of p-values in conjunction with a description of the various positive and negative associations between the response and the factors in question ensues. The real question of interest be...

On-line learning in environments and applications with time-varying behavior pose serious challenges. Changes may lead the learning model designed with old data, to become inconsistent with the new data, so that adaptation strategies are necessary. Unfortunately, most adaptation strategies are performed only on a batch basis, i.e. after accumulating certain number of samples. This process usual...
