3. The method of claim 2 , wherein the additional set is selected based on an entropy-based interaction measure.
2. The method of claim 1 , wherein the learning comprises: refining the local learning models for pairs of the data elements that are linked by the dynamic features, through one or more levels of refinement, wherein at each subsequent refinement level, estimations of assigning labels from an additional set of neighbor elements linked by the dynamic features are derived.
