Abstract
In recent decades, the volume of information that is computerized in the databases of
data from most organizations and companies has grown dramatically. Their analysis
is a great knowledge for companies that helps when making decisions. Without
However, the dispersion of these data, in different formats and of large volume, is a challenge
that can be solved with data mining techniques and tools. With the evaluation of
AI, from VRAIN of UPV mining models are generated predictive and descriptive data,
evaluation of data mining models based on costs and adaptation/contextualisation
models for your application. Among its benefits is the optimization in the use of
data mining models and the inclusion of costs in the evaluation of models.
