Embodiment Construction

[0048] In order to enable those skilled in the art to better understand the present invention, exemplary embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] In an exemplary embodiment of the present invention, automatic feature combination is performed by performing at least one binning operation on a single continuous feature to generate one or more binning features corresponding to the single continuous feature, and combining these binning Combining the binning group features composed of bin features with other discrete features (for example, a single discrete feature and / or other binning group features) can make the generated machine learning samples more suitable for machine learning, so that better predictions can be achieved result.

[0050] Here, machine learning is an inevitable product of the development of artificial intelligence research to a certai...

Abstract

The invention provides a method and a system for generating combined features of machine learning samples. The method comprises the steps: (A) obtaining a data record, and the data record comprising multiple pieces of attribute information; (B) for each continuous feature generated based on the multiple pieces of attribute information, executing at least one binning operation to obtain a binning group feature composed of at least one binning feature, and each binning operation corresponding to one binning feature; and (C) generating a combined feature of the machine learning sample by feature combination between binning group features and / or other discrete features generated based on the plurality of pieces of attribute information. According to the method and the system, the obtained binning group features are combined with other features, so that the combined features forming the machine learning sample are more effective, and the effect of a machine learning model is improved.

Description

[0001] This application is a divisional application of a patent application with an application date of July 20, 2017, an application number of 201710595326.7, and a patent application entitled "Method and System for Generating Combined Features of Machine Learning Samples". technical field [0002] The present invention generally relates to the field of artificial intelligence, and more specifically, relates to a method and system for generating combined features of machine learning samples. Background technique [0003] With the emergence of massive data, artificial intelligence technology has developed rapidly, and in order to mine value from large amounts of data, it is necessary to generate samples suitable for machine learning based on data records. [0004] Here, each data record can be regarded as a description about an event or object, corresponding to an instance or example. In a data record, there are items that reflect some aspect or nature of an event or object,...
