Embodiment Construction
[0047] The present invention is described in further detail now in conjunction with accompanying drawing.
[0048] Such as figure 1 As shown, the core steps of this method are as follows:
[0049] 1. Establish a dual-objective model of the cluster number k value and the fuzzy clustering index of the data set to be tested.
[0050] 2. Set the maximum number of iterations of the optimization algorithm, and randomly generate the parent solution, and generate the offspring solution through the hybrid mutation operation of the parent solution. Then combine the child solution with the parent solution, and perform an environment selection operation on the set to obtain the current Pareto non-dominated solution, and increase the number of iterations by one. When the number of iterations reaches the maximum number of iterations, the Pareto frontier of the dual-objective model is obtained according to the clustering k value obtained.
[0051] 3. Combining the Pareto frontier correspo...
