Result N new = N + 3 Σ k=2 N C k,  N new is the number of sample in the new database,  N is number of original samples  N C k is the Combination operation, 6 C 2 = 15. N new = N + 3(2 n – 1)

Conclusion & Future Work Show good promises. Merging features from parents. Weight Vector analysis.  Balance between uniqueness and realism.
