Embodiment Construction

[0030] 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 creative efforts fall within the protection scope of the present invention.

[0031] see figure 1 , the present invention provides a technical solution: a sorting weight update method, characterized in that:

[0032] S01: Design sorting algorithm

[0033] score=w 1 *x 1 +w 2 *x 2 +w 3 *x 3 +...+w n *x n +b

[0034] x is the feature value, w is the weight, and b is the bias;

[0035] S02: Regularly train samples to obtain the latest weight value and save it

[0036]

[0037] It is known that the average value of the measured da...

Abstract

The invention discloses a sorting weight updating method in the technical field of weight updating. The sorting weight updating method comprises the steps of S01, designing a sorting algorithm; s02, periodically training the sample to obtain a latest weight value, and storing the latest weight value; s03, calculating scores of the to-be-sorted articles by using the latest weight; and S04, assembling and displaying the sorting results in an inverted order according to the scores. According to the method, the problems of automatic calculation and automatic updating of the sorting feature weightare solved, the sorting algorithm of the original manual weight is kept unchanged, only the weight is obtained by machine learning training instead of manual setting, different sorting scenes are supported, different weights are trained, automation is realized, and the problem of manual weight debugging is avoided.

Description

technical field [0001] The invention relates to the technical field of weight updating, in particular to a sorting weight updating method. Background technique [0002] Weight refers to the importance of a certain factor or indicator relative to a certain thing. It is different from the general proportion. It not only reflects the percentage of a certain factor or indicator, but emphasizes the relative importance of a factor or indicator. , tending towards contribution or importance. Usually, the weight can be judged and calculated by dividing multiple levels of indicators. Commonly used methods include AHP, fuzzy method, fuzzy analytic hierarchy process and expert evaluation method; two refers to contribution; three refers to rights and power. [0003] In actual business, sorting is often used. The weights of sorting features are often set manually based on experience. This method is difficult to grasp how much the specific setting is appropriate. At the same time, the ...
