Many data sets are incomplete. For correct analysis of such data, one can either use algorithms that are designed to handle missing data or use imputation. Imputation has the benefit that it allows for any type of data analysis. Obviously, this can only lead to proper conclusions if the provided data completion is both highly accurate and maintains all statistics of the original data. In this paper,...
The requirement that the models resulting from data mining should be understandable is an uncontroversial requirement. In the data mining literature, however, it plays hardly any role, if at all. In practice, though, understandability is often even more important than, e.g., accuracy. Understandability does not mean that models should be simple. It means that one should be able to understand the predictions...
Many databases will not or can not be disclosed without strong guarantees that no sensitive information can be extracted. To address this concern several data perturbation techniques have been proposed. However, it has been shown that either sensitive information can still be extracted from the perturbed data with little prior knowledge, or that many patterns are lost. In this paper we show that generating...
