Abstract

The invention relates to an automatic feature generation system, which comprises: a data table analysis unit for analyzing a data table input by a user; a user interface unit which is used for presenting an analysis result of the data table analysis unit, receiving a use field selected by a user and receiving a data table association relationship configured by the user; a data processing unit which is used for extracting data corresponding to the sample according to the data table relation structure; a feature generation unit which is used for selecting a proper feature generation algorithm togenerate features according to the data table relation structure; and a feature processing unit which is used for carrying out feature analysis on the generated feature data. The invention further correspondingly provides an automatic feature generation method. According to the method, a user is not required to have any technical ability and generation logic, only a small amount of information about which original data is used for generating features is required to be provided, and full-process processing of feature generation is automatically completed.

Description

technical field [0001] The present invention relates to the technical field of machine learning, and more specifically, to an automatic feature generation system and method. Background technique [0002] With the popularization of big data artificial intelligence technology, the method of data analysis and processing through machine learning algorithms is gradually adopted by engineers in various industries. The input data of a machine learning algorithm is called features, which are processed from raw data through a series of engineering methods. At present, there are many mature products for the automatic modeling method of features or the system of the present invention, but the system product of the present invention for automatically processing raw data to generate features is still in the research stage. The existing system products of the present invention that include feature generation are as follows: [0003] (1) A data platform that integrates manual feature ext...
