Problems solved by technology

For the data preprocessing method loaded one by one, its processing efficiency is low, and as the amount of data increases, the processing efficiency declines more obviously. In addition, this data processing method is difficult to expand; using Hadoop and other big data technologies for data processing, although High processing efficiency, but the development and operation and maintenance costs of Hadoop-based distributed programs also increase

Abstract

Embodiments of the present invention provide a method of preprocessing data. The method comprises the following steps of: extracting a characteristic variable of a source data set; Determining a feature interval of a source data set according to the feature variable; Dividing the feature interval into a plurality of sub-feature intervals; Processing data belonging to the plurality of sub-feature intervals. The invention improves the efficiency of data preprocessing and enhances the expandability of the data preprocessing module without increasing the operation and maintenance cost. In addition, embodiments of the present invention also provide an apparatus for preprocessing data, a piece of equipment, and a computer-readable storage medium.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data mining, and more specifically, embodiments of the present invention relate to a method for preprocessing data, a device for preprocessing data, a device, and a computer-readable storage medium. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Data preprocessing refers to some processing of data before the main processing. The data in the real world are generally incomplete and inconsistent dirty data, which cannot be directly used for data mining, or the mining results are not satisfactory. In order to improve the quality of data mining, data preprocessing technology is produced. There are many methods of data preprocessing: data cleaning, data integration, data transformat...
