Problems solved by technology

The logic structure of the first algorithm is repetitive and long. For classification problems with many categories, the classification efficiency will be greatly reduced, which will affect the performance of the algorithm.
For the second method, the softmax regression method is adopted, but the random factors in the sample will be ignored

Abstract

The invention discloses a data classification method, which comprises the following steps: determining the probability that a prediction data set respectively belongs to each category; Constructing probability intervals belonging to each category of the prediction data set according to the probability; randomly generating a random number between [0, 1] is randomly generated, and determining a category of the prediction data set according to a probability interval in which the random number is located. A data classification apparatus is also disclosed. This scheme is mainly applied to the multi-class classification problem in machine learning field. This method not only enriches the internal logical structure of multi-class logistic regression algorithm, but also enhances the performance of multi-class logistic regression algorithm by judging the class and fully considering the influence of training sample error.

Description

Technical field [0001] The invention relates to data processing technology, in particular to a method and device for data classification. Background technique [0002] Multi-class logistic regression algorithms in machine learning generally have two logical structures. One is to establish a corresponding logistic (logical) classifier according to each category. The other is to improve the loss function of logistic regression to meet the needs of multiple classification problems. The logic structure of the first algorithm is repetitive and long. For classification problems with many categories, the classification efficiency will be greatly reduced, which will affect the performance of the algorithm. For the second method, the softmax regression method is adopted, but random factors in the sample will be ignored. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a method and device for data classification, which can fu...
