Method and device for automatic prediction of a value associated with a data tuple

Device for automatic prediction of a current value using a weighted average of a number of current reference values, the current value being associated with a current pair consisting of a first and a second current data tuple, said device comprising

• means storing a set of pairs of first and second reference data tuples and associated reference values,
• retrieving means for selectively retrieving the current reference values from the storing means, said means for retrieving being adapted for using a set of reference pairs, each reference pair consisting of a first and a second reference data tuple and being associated with a reference value, wherein the first reference data tuples, the first current data tuple and a first metric is used for selecting,
• means for determining, for each current reference value, an associated weight using the second reference data tuples of the pair associated with the respective selected reference value, the second current data tuple and a second metric, and
• means using the current reference values and the determined weights for determining the weighted average.
