Bayesian classifiers such as Naive Bayes or Tree Augmented Naive Bayes (TAN) have shown excellent performance given their simplicity and heavy underlying independence assumptions. In this paper we introduce a classifier taking as basis the TAN models and taking into account uncertainty in model selection. To do this we introduce decomposable distributions over TANs and show that the expression ...

14 Convergent evidence suggeststhat the basal ganglia support reinforcement learning by adjusting 15 action values according to reward prediction errors. However, adaptive behavior in 16 stochasticenvironments requires the consideration of uncertainty to dynamically adjust the 17 learning rate. We consider how cholinergic tonically active interneurons (TANs) may endow the 18 striatum with such ...

The increasing popularity of open standards in B2B e-commerce demands more research on generalized trust. This study investigates how a country’s social trust affects the use of open and closed B2B ecommerce. The analysis based on data from 27 European and related countries shows that social trust in a country promotes the use of open B2B e-commerce, but it impedes the use of closed B2B e-comme...

Probabilistic networks (Bayesian networks) are suited as statistical pattern classifiers when the feature variables are discrete. It is argued that their white-box character makes them transparent, a requirement in various applications such as, e.g., credit scoring. In addition, the exact error rate of a probabilistic network classifier can be computed without a dataset. First, the exact error ...
