WitrynaThe simple naive greedy algorithm [12] adds nodes to the neighborhood until there is no further reduction in conditional entropy. This will happen when the true neigh-borhood is a subset of the estimated neighborhood. Our key observation here is that the last node to be added by the naive greedy algorithm will always be in the true neighborhood.
