Abstract： |
The invention relates to a data digging character choosing method based on mixed inter-information in the field of data processing technology. The method comprises: assigning D attributes to form a choosing attribute integer F in the data form, arranging character attribute integer S as vacuum integer, computing the inter-information of any attribute fi of F and the class number attribute C, choosing the attribute fi of the max inter-information I, extracting the fi from the F and adding the fi into S, repeating the steps a and b until the ending condition: a) computing the inter-information HMI to any attribute fi of F; b) choosing the attribute fi of the max HMI, extracting the fi from the F and adding the fi into S, inputting the character attribute S as the input attribute of the data digging. |
