Understanding and predicting the choices and preferences of users is a challenging task: real-world scenarios involve users behaving in complex situations, where prior beliefs, specific tendencies, and reciprocal influences

Bayesian Modeling,rate prior knowledge about the domain of .. Prior knowledge can be combined with observed data to determine the final optimal parameter set .. Rather than optimizing the likelihood, we concentrate on the probability .(.|.) and seek the set of parameters that maximizes it. By exploiting Bayes’ theorem, the likelihood can be expressed as

Conclusions,re is not the general superiority of probabilistic methods. It is well-known, e.g., from the Netflix prize, that the best approaches count an ensemble of methods that cooperate for a best prediction. Nevertheless, as also witnessed by the studies discussed in this book, probabilistic methods can play a prominent role within such ensembles.

It was seen that a firm’s strategic position should be different from its competitors’ and that competitive advantage stems from these differences. It has been shown that information systems should be designed to fit in with, and support business strategy, and that information system desi
