dcterms:description
The paper is concerned with mining data which do not have uniform structure, e.g. they represent repeated measurements of different objects in the case the observation period is not fixed. The available data have to be transformed and preprocessed in such a way that uniform type of information is obtained about all the considered objects. This can be achieved e.g., by aggregation. But this process can bring in anachronistic variables, i.e., variables containing information which is not actually available in the data when a prediction is needed. The paper suggests a method how to preprocess considered type of data without falling into the trap of introducing anachronistic attributes.
