Title: SERVICE PARAMETER SELECTION METHOD AND RELATED DEVICE
Abstract:
A service parameter selection method and a related device introduced in the embodiments of the present application. The method comprising: firstly configuring a first candidate sample set, wherein the first candidate sample set comprises a plurality of candidate samples; acquiring an IV value of each of the candidate samples in the first candidate sample set; determining a candidate sample, in the first candidate sample set, with the IV value greater than a pre-set threshold value as a first primary selection sample, and storing the first primary selection sample in a second set of samples to be selected; using stepwise discriminate analysis and/or cluster analysis to process the second set of samples to be selected so as to obtain a target sample having a significant standard, wherein the target sample is used for determining the service parameter; using the IV value to remove an insignificant variable to obtain the second set of samples to be selected; and performing stepwise discriminate analysis and cluster analysis on the second set of samples to be selected so as to obtain a target sample having a significant standard. By means of the method, the diversity of variables is guaranteed, an existing variable selection process is optimized, and the problem of losing variable information during a dimension reduction process is reduced.
