Problems solved by technology

However, when the business is complex or there are many recommended bits, it will not only cause a lot of repetitive code development and reduce the work efficiency of the algorithm engineer, but also need to modify the source code of the recommended project and re-launch the system every time a new feature is added or modified. Increase the risk of online system
In addition, because the specific recommendation business independently develops its own feature modules, it is difficult to completely guarantee data consistency even if the feature logic is consistent

Abstract

The invention discloses a feature calculation system and method, a storage medium and electronic equipment, and relates to the technical field of data processing. The feature computing system includes: a feature client, including a plurality of feature computing plug-ins for receiving a feature computing request, and the feature computing request includes a feature token; according to the feature token, the feature computing plug-in required for feature computing is obtained from the feature configuration guard module and feature calculation plug-in parameters; perform feature calculation based on the feature calculation plug-in and feature calculation plug-in parameters and based on the feature data obtained from the feature data server; feature configuration management module is used to receive feature configuration and feature configuration performed by developers through the feature configuration interface It includes a feature calculation plug-in and parameters of the feature calculation plug-in; a feature configuration watchdog module, which is used to monitor the feature configuration on the feature configuration management module, and load the feature configuration to make the feature configuration take effect. The present disclosure can realize unified management and configuration of feature calculation.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular, to a feature calculation system, a feature calculation method, a storage medium, and electronic equipment. Background technique [0002] With the advancement of technology in various industries, intelligence has become the trend of social development. As one of the core technical means of intelligence, machine learning has produced good results in various fields. For example, in the field of e-commerce, the use of machine learning can match the needs of users, improve the shopping experience of users, increase the user stickiness and activity of the website, and thus bring about the continuous growth of Gross Merchandise Volume (GMV). [0003] In the process of machine learning, feature calculation based on raw data has become an indispensable and very important step. Still taking the e-commerce field as an example, since the personalized service of e-commerc...
