Abstract

The invention relates to the technical field of computers, and provides a variable binning method, a variable binning device, terminal equipment and a storage medium. The variable binning method comprises the steps of acquiring sample data; according to preset variable configuration, determining nominal variables to be binned and feature values corresponding to the nominal variables from the sample data; storing the feature values into a preset feature value set; aiming at each feature value in the feature value set, diving the nominal variables into two bins by using the feature value as a test split point, and computing an associated index value corresponding to each feature value; using the feature value corresponding to the maximum in the associated index values as a target split pointto execute a binning operation; and removing the feature value from the feature value set; and when a binning result reaches a preset bin number threshold, stopping binning, and otherwise, continuously executing the binning operation. According to the technical scheme provided by the invention, the binning operation is automatically performed on the nominal variables based on the associated indexvalues, manual intervention and consumed time are reduced, and the binning efficiency of the binning operation is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a variable binning method, device, terminal equipment and storage medium. Background technique [0002] At present, the common binning method is equal-width binning or equal-frequency binning. Equal-width binning refers to dividing the value range of a feature into a interval of equal width, and each interval is regarded as a binning. Binning refers to arranging the eigenvalues ​​in ascending order, and dividing them into parts a according to the number of eigenvalues, and each part is regarded as a binning. However, whether it is equal-width binning or equal-frequency binning, it is necessary to manually set the number of bins in advance. If the number of bins is too small, more information will be lost. If the number of bins is too large , the purpose of binning cannot be achieved. [0003] If after equal-frequency binning or equal-width binning, manual merging is p...
