                         the estimation of a W-operator from training data. The idea is to 
                         choose a subset of variables W that maximizes the information 
                         observed in a set of training data. The task is formalized as a 
                         combinatorial optimization problem, where the search space is the 
                         powerset set of the candidate variables and the measure to be 
                         minimized is the mean entropy of the estimated conditional 
                         probabilities. As a full exploration of the search space requires 
                         an enormous computational effort, some heuristics of the feature 
                         selection literature are applied. The proposed technique is 
                         mathematically sound and experimental results show that it is 
                         adequate in practice.",
