Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0029] see figure 1 , the present invention provides a technical solution: a feature selection method for complex pattern classification, the specific steps of the feature selection method for complex pattern classification are as follows:
[0030] S1: The continuous features in the discretized data set D, the result is represented by D, and the sum of the Gini coefficients of each feature is Sum(D i ) is set to 0;
[0031] S2: Calculate the Gini coefficient...
