Abstract

The invention discloses a method and device for dynamically adjusting a feature library, and relates to the technical field of computers. One specific embodiment of the method comprises the followingsteps: receiving feature data transmitted by an upstream service component through an interface to obtain a data set based on different service types; labeling the data of all the service types according to a preset attribute label, and classifying the data into a data table corresponding to the label; calling a preset matching model, and generating a target data wide table based on the pluralityof data tables so as to store the target data wide table into a corresponding target feature pool; when a data request of an external application model is received, obtaining a feature variable in therequest, and further obtaining corresponding feature data from the target feature pool to generate a feature data set and output the feature data set. According to the embodiment of the invention, the method can solve a problem that the feature data needed by the training iteration of a conventional model is difficult to obtain and is poorer in quality.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for dynamically adjusting a feature library. Background technique [0002] Risk control technology is an important guarantee for the healthy operation and management of the banking system and even the entire financial system. Traditional risk control management mainly relies on expert business experience methods, which can no longer meet the needs of the current banking system development. The core of risk control technology lies in the development and application of risk models. The machine learning algorithm modeling method based on big data and artificial intelligence technology. The contribution and effectiveness of risk model characteristic data to the model may change over time. The feature library needs to be adjusted regularly to maintain the validity and stability of the model. [0003] In the course of realizing the present invention, the inventor...
