查询词典 diversity

The local decision space partitioning is given in the sense of maximum Bhattacharyya distance criterion. The optimality and the non-triviality of the partitioning scheme are proved. The reasonability of using Bhattacharyya distance as partitioning criterion is analyzed. The simulation results show that the partitioning method based on Bhattacharyya distance criterion is superior to that based on J-diversity criterion.
