Auxiliary function used by MLUL. For each instance in the dataset, given the neighbors structure, we compute its reverse nearest neighbors
getAllReverseNeighbors(d, neighbors, k)
A list of vectors with the indexes of the reverse nearest neighbors of every instance in the dataset
Vector with the instances of the dataset which have one or more label active (ideally, all of them)
Structure with the neighbors of every instance in the dataset
Number of neighbors to be considered
