Example Embodiment
[0048] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar meanings throughout. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present invention, but should not be understood as limiting the present invention.
[0049] figure 1 It is a schematic diagram of the overall process structure of the present invention. As shown in the figure, the present invention provides a hybrid feature selection method based on harmony search. First, process the original feature set of social network users; then use the combination of information gain, Relief algorithm and chi-square statistics to select a subset of features and initialize the harmony memory. Finally, the optimal feature subset is selected using harmony search and rough dependence function. Specific steps a...
